Foreword
Hello, and welcome to my personal headcanon of the Legendary Pokémon! *cue a dramatic "dun, dun, DUUN" sound effect*
Now, before I'm actually going to jump in and explain every single thing in this, I just want to say that some of the things that you're about to read might come across as a bit bizarre, abstract, and/or straight out just simply unconventional. However, instead of trying to bitch at me and tell me WHY some of the elements presented in here just wouldn't make any goddamn sense, at least TRY to enjoy it for what it is – and if not, just for the pure silliness behind it.
There, now that we've gotten that out of the way, how about we just jump right in, hmm?
Just like the vast majority of the people who grew up in the '90's, I was introduced to the Pokémon franchise originally through the games. I was very young, and I didn't know ANY English whatsoever, so between playing the games whose graphics actually made me feel a bit nauseated while looking at them that was only written in English, and an animated TV-series that was dubbed in Swedish, you can obviously guess that I tuned in more to the anime, despite its flaws; and ever since then, I've always had this nostalgic love for the franchise, occasionally tuning to Bulbapedia to read about recent events. Sure, I haven't actually touched any of the games since Colosseum, nor watched the anime recently, let alone having actually read the "official" manga (seriously, last time I checked, there was no official manga, but a manga that Satoshi Tajiri has said that he "liked"), but I do feel safe to say that I still enjoy Pokémon, even to this day.
This idea originally came to me when I was accidentally surfing up on some Pokémon fanfics, more specifically the ones about the Legendary Pokémon. For those of you who don't know, I love all of the Legendary Pokémon, even the ones that are so horribly idiotic design-wise, or weak stats wise (my non-Legendary Pokémon faves would have to be the Eeveelutions, most of the Fire-starters, and some other Pokémon I always keep on forgetting), and all I can say is that I'm honestly surprised that, well, not many fanfic writers have picked up on telling stories about them. Oh, don't get me wrong, there are a lot of fanfics about the Legends out there, including the occasional portion of a normally non-Legendary centric fic having them in there somewhere (one very good example is the PokéWars-series, which happens to be one of my personal fanfics of all time), but in comparison to stories that centers around non-Legendary Pokémon, or even the humans, then… yeah, the Legends almost always seems to take a backseat in that regard. Almost being the keyword. Even though from my own personal point of view, their stories are always much more fun to read about, as that's where some people can truly show how creative they can get with their personalities.
Anyway, I've been working on this document for a while now, and it's always ever-changing, ever-growing, so stay tuned for any updates I add in the future!
--------------------------------------------------------------------------------------------------------------------
Legendary Pokémon and the gender issue
As we all know, most of the Legendary Pokémon are considered genderless, despite having either feminine or masculine voices in their movies/specials/whatevs. This particular statement will stay true in my headcanon, however… all of the genderless Legends are allowed to pick just about any gender they want. Arceus and Mew are perfect examples of this in my headcanon, as they will change their genders CONSTANTLY, sometimes on a whim.
As for their telepathic voices, this is where it gets a little more interesting (or complicated, depending on your POV) – all of the Legends, including those we've never actually heard say anything in the movies/episodes/specials/whatevs that we've seen so far, has the ability to speak telepathically. The reason for why some them vehemently refuses to use this particular ability could be for various reasons – they either don't fully trust any of the humans nearby, or they just like to mess around with them by not saying anything and just let them guess… which unfortunately has the disadvantage of the humans accidentally turning on them when that was never the actual plan.
However, what's definitely noteworthy among the Legends regarding this ability is that this is where some of the Psychic Legends (along with Arceus whenever it uses the Mind Plate) truly gets to show their powers outside of battling – not only are they able to communicate with one another without dragging another human in to listen on their conversations, but they also have the ability to alter their voices to sound like a completely different gender than what one would perceive them to actually be. For an example – Lugia, a Psychic/Flying type, is notorious for using a male voice whenever it wants to talk to either humans or non-Legends, as it's come to the conclusion that everyone would only listen if it spoke in a male voice due to alleged power behind it, but prefers to use a feminine voice when around its fellow Legends, and ultimately it prefers if people do refer to it as a female.
Also, in order to make this a little bit more easy to tell what genders these Legends prefer to be called, I'll be giving you a list:
Articuno: Female
Zapdos: Male
Moltres: Female
Mewtwo: Male
Mew: Unknown, switches constantly
Raikou: Male
Entei: Male
Suicune: Female
Lugia: Female
Ho-Oh: Male
Celebi: Female
Regirock: Male
Regice: Female
Registeel: Female
Kyogre: Unknown, switches constantly
Groudon: Unknown, switches constantly
Rayquaza: Male
Jirachi: Male
Deoxys: Unknown, switches constantly
Uxie: Male
Mesprit: Female
Azelf: Male
Dialga: Male
Palkia: Female
Regigigas: Male
Giratina: Male
Phione: Female
Manaphy: Male
Darkrai: Male
Shaymin: Female (Land forme), Male (Sky Forme)
Arceus: Unknown, switches constantly
Victini: Male
Cobalion: Female. but prefers to be viewed as a male at all times
Terrakion: Male
Virizion: Female
Reshiram: Male
Zekrom: Female
Kyurem: Male
Keldeo: Male
Meloetta: Female
Genesect: Male
Xerneas: Female (for now - once the games comes out and we get to know a bit more about Xerneas and Yveltal, I'll probably come back on this particular issue and/or change some things)
Yveltal: Female (for now - once the games comes out and we get to know a bit more about Xerneas and Yveltal, I'll probably come back on this particular issue and/or change some things)
"Gijinka" forme
In my headcanon, all of the Legendary Pokémon, including those who are officially classified as genderless, are able to take on human-like forms, or "Gijinka" formes, as some like to call them.
In this form, all of the Legendary Pokémon essentially look like human copies of themselves, carrying certain traits from their original forms (like the color of their eyes (and yes, that includes the black, red, yellow, or even red parts outside of the irises); and their clothes, regardless of what style they actually wear, almost always having an identical pattern to their original forms, as the Legends seems to prefer these particular clothes over more "normal" ones). In the case of the genderless Legends, while they're in this form they're also able to switch from one gender to the next whenever they see fit; despite this, most of them prefers to keep one gender at all times.
This form is mostly used by the Legends when they want to get acquainted with one another on a more "personal" level; to them, showing off their Gijinka forme is a way of telling one another that they wish no harm. However, recently there have been instances where the Legendary Pokémon has shown to switch between these two forms around humans they know can keep their identities a secret.
Aside from the exclusion of having the ability to fly and/or hover off the ground, all of the Legends retain most of their powers, though said powers have been reportedly weakened.
Fertility
Contrary to popular beliefs, all of the Legendary Pokémon are able to reproduce; the reason why there aren't that many around is simply because of a law brought forth by Arceus following the birth of the Legendary birds (Articuno, Zapdos, Moltres). Despite this law having dictated the Legends' lives for several centuries, there has been the occasional loophole in the form of Mew. Manaphy was originally considered to have been the other exception, but after realizing that its population was proving to be "too difficult to handle", Arceus had personally altered their genes so that they would not carry any more Manaphy unless the species was facing extinction, but rather only be able to reproduce another form of Pokémon; Phione.
No one is absolutely sure why these two particular Pokémon have (or technically had, in the case of Manaphy) managed to escape from being punished by Arceus every time they did reproduce, although it's heavily rumored among some of the other Legends that the Mews are unable to keep one particular station all their lives, and thus need to repopulate. One (or even two, though that's an extremely rare phenomenon) could be "free" to roam around the world trying to find their destiny, while another would have to stick to certain posts.
Although Arceus does severely condemn the idea of its fellow Legends producing children left and right (unless they're Mew or even Manaphy), he has allowed them to seek out mates. "In return, you have to promise me that there are to be no children born from these unions." Since everything Arceus says is law, the Legends are unable to protest and just take what they can get, barely feeling grateful to the God's act of generosity.
Much like the rest of the non-Legendary Pokémon, the Legends, including the ones who do look like mammals, are only able to produce eggs. However, whereas the non-Legendary Pokémon appear to be able to lay their eggs almost a month after conception, the Legends take a much longer time to do with, with 3 months being the norm for most of them.
Views on... certain types of relationships
Due to the fact that the vast majority of the council of Legendary Pokémon are genderless, same-sex relations is rarely, if ever, frowned upon. The only real reaction one might get from them is just a mere shrug and a "whatever" before they go back to doing what they did earlier before the big announcement. Despite this, some of the much younger Legendaries, such as Latios, are still a bit miffed over the whole same-sex thing, though it's nothing too serious.
Instead, the only real instance one might get mixed feelings from these Legends is when one brings up the idea of Legendary Pokémon mating with non-Legends, including humans, as even the most open-minded will turn away in disgust if the latter part is brought up (that is, unless they do have feelings for any particular humans in mind). While these particular practices aren't unheard of, most of them refuses to fully acknowledge it, with some of the Legends even asking for a law that'd outright ban the possibility of poképhilia.
--------------------------------------------------------------------------------------------------------------------
Articuno, Zapdos, Moltres
Probably one of the largest risks I'm taking in this headcanon outside of the whole gender issue-thing and the mere mention of Poképhilia: Articuno, Zapdos, and Moltres are the biological children of Ho-Oh and Lugia. While they're perfectly aware of the fact that Lugia is their mother, they've as of yet to find out that Ho-Oh is their sire, and this WILL come back to haunt Lugia later on.
I honestly don't know yet why Ho-Oh and Lugia had seemingly split up after Lugia has laid the eggs, but I honestly wouldn't be surprised if Arceus had a say in this somehow. Only after the eggs have hatched and the trio have learned how to fly and take care of themselves does Lugia leave for Ecruteak City, taking perch on what would soon be known as the Burnt Tower, and the tower duo try to start over. Unfortunately, shit happens which I'll be explaining in their section, and the Burnt Tower burns to the ground, causing Lugia to flee for Whirl Island after being threatened to be burned alive by her ex once he catches up. (again, this will be explained in hopefully much greater detail in Ho-Oh and Lugia's section) Anyway, at some point, Lugia is reunited with her children, and she starts to take up guardianship of the trio.
Of all the three, Articuno develops a very close, intimate relationship with their mother. According to Lugia herself, Articuno is the most easiest to talk to because of the ice bird's mellow demeanor and the two generally sharing rather common opinions of the behavior of many of their fellow Legends. Articuno has often been the one Lugia would begrudgingly turn to for comfort if her thoughts would get the better of her, and in turn the sea guardian has often been quick to not only give the ice bird some helpful advice in her time of need, but even defended her against Moltres whenever the phoenix would go too far. However, unbeknownst to Lugia, Articuno has developed a kind of complex for her, a fact which appears to greatly irritate Ho-Oh every time he sees the two together.
At first sight, Articuno may instantly comes across as either this total ice queen or just a downright bitch, but that's just how she behaves. Taking her status very seriously, she rarely has time to think about childish nonsense as romance and such, and instead tries to foster friendship with some of the other Legends (and non-Legendary Ice-types). In comparison to either of her siblings/counterparts and best friend Suicune, Articuno is perhaps the most down to earth, but still suffers from a bit of vanity, although it's nothing too dangerous.
Zapdos, if one wants to be very blunt, is an attention whore through and through who'll happily do everything in his power to gain just the slightest bit of that attention, no matter how dangerous that might be. Usually seen hanging out with his "bro", Raikou, Zapdos can be seen by many as a bit of a bully and a hooligan, especially when he's drunk. Which he happens to be very often. Both Moltres and Articuno has lost count on how many times they've found him drunk in some alley, beaten to a bloody pulp while laughing and/or slurring out some incoherent stuff.
Although he can easily come across as this big moron, Zapdos has been known to occasionally crack out some pretty damn insightful stuff, all mostly based around his blunt, honest outlook on life, all spoken of in a way that many has found themselves agreeing on, drunk or sober.
Whereas she had a lot easier to bond with Articuno or being generally neglectful towards Moltres, Lugia has stated on several occasions that she finds Zapdos to be incredibly difficult, as she's often forced to combat stubbornness with stubbornness, and occasionally even raw power, to make Zapdos listen, as the thunder bird rarely wants to listen to logic. However, much like the rest of his siblings, Zapdos does care immensely for his mother - in his own way of course - and has been known to get easily offended if someone does speak wrongly of her.
Which brings us to his relationship with Ho-Oh - the one Legendary Pokémon who's become a thorn on his mother's side, and who's constantly threatened to set her on fire whenever they're in the same place, or simply insult her over how "plain" and "ugly" she looks while commending himself on his own beauty. Surprisingly enough, in comparison to both of his siblings, Zapdos is generally indifferent to the Rainbow Pokémon's very presence unless he'd directly attack Lugia.
Moltres is, out of the entire trio, probably going to be a bit more controversial in her own personal storyline. Nice only when she feels like it, followed by her easily losing her temper around her siblings/counterparts, Moltres is a bit of a tough cookie to crack when meeting her for the first time, and her huge pride really doesn't help her much in the long run. Once you do get to know her better, you can truly see her for the fragile little thing with no real self-confidence in herself that she is. If anyone could tell you how being a fire-type sucks, it would definitely have to be her.
Due to her many harsh encounters with Ho-Oh and then being subjected to his many fire attacks and just generally being on edge due to his threats of setting her on fire if he ever caught up with her, Lugia has come to develop an intense fear for fire. As such, just simply being around Moltres in very close proximity has the sea guardian being nearly skittish. Even when you do take away her fire-typing, Lugia and Moltres' relationship isn't exactly the best, as the sea guardian has found Moltres to be the most difficult to deal with due to her pride and need for attention out of all her children, and often gets very frustrated trying to argue sense her. Despite this, Lugia has refused to truly give up on the girl, and is trying her hardest to keep Moltres focused, but often worries what might happen if the phoenix's pride got way too out of hand.
Whereas her siblings has been known to get out of their comfort zones and just simply hang around with the other Legends, Moltres rarely leaves hers, and seems to generally be the more withdrawn than even her sister. This, coupled with how much Lugia appears to favor the other two over her and the way they generally treat her, has her grow into a very frustrated individual, and very jealous of her siblings - a fact she makes perfectly clear whenever the two do rile her up (accidentally on Articuno's part).
So it's no real surprise that eventually, Moltres started to turn her attention towards Ho-Oh during a time when the latter's relationship with her mother was at its absolute worst.
Ho-Oh, seeing this as a way to hurt his ex-girlfriend even further and as a way to bond with at least one of his children, starts to sneak around with Moltres and not only bond with her by listening to her rambling on about her insecurities and offer her a wing and a shoulder to cry on while giving her some advice, but also teach her how to even be more of a pain in Lugia's ass than she already was. For the first time in a very long time, the phoenix could finally bring herself to smile and just be happy - at least whenever she wasn't bothering her mother or her siblings. She even started to spend some time with the other Legends, particularly with some of the other flying Pokémon.
Moltres, not knowing what her actual relations to him were nor that he was once her mother's significant other whom the latter still loved, eventually found herself falling in love with the Rainbow Pokémon, but she refused to tell him that for fear of possible rejection and the possibility of losing the one person she truly cared for outside of the family image that she knew.
Then one day, Ho-Oh had just up and left, apparently leaving for Orre to go help someone. At that moment, Moltres finally came to realize that her mother had gone missing, a fact that caused a very huge ruckus among some of the Legends. When Ho-Oh still didn't return for several months, Moltres grew insanely worried about the other, only for her to become relieved when she saw both him and Lugia returning, with only some very minor cuts on their bodies that would heal very quickly. Whereas her siblings gushed over their mother, Moltres had instead flown over to Ho-Oh's side, clinging onto him while completely ignoring the stares the two got (along with one very poignant look from her mother).
However, unbeknownst to her and her siblings, whatever had happened in Orre would eventually come to change their lives, as only three months later, Ho-Oh became Lugia's mate once more, and this time permanently.
Naturally, this did not bode well for Articuno and Moltres (Zapdos only gave out a weak protest before he sunk into obscurity, as in his mind, this really didn't bother him too much), but for obviously different reasons; Articuno because of the past the two birds shared, and Moltres simply because of the fact that she was in love with him.
Although she'd clearly lost her chance with Ho-Oh to her very own mother, Moltres still refused to fully give up, and tried to seduce him away from Lugia. Ho-Oh, being perfectly clueless to what was going on other than that he'd clearly gotten her upset over something, merely thought that she'd probably stolen some of Zapdos' booze and whatever she did was caused by the alcohol in her system. When Lugia, after listening to Ho-Oh telling her about how Moltres was behaving, tried to confront the phoenix, all she got was nothing more but pure silence and refusal to look her in the eyes. Realizing that Moltres just wasn't going to tell her, Lugia dropped her interrogation.
And then, just a few weeks afterwards, news spread among the Kanto and Johto Legends about Lugia's pregnancy.
Articuno, still not having gotten over the fact that Ho-Oh had claimed their mother just seemingly out of the blue (along with having found out about Ho-Oh's actual relations to her, Zapdos and Moltres when accidentally eavesdropping on the two), was clearly horrified at the news, but tried to behave herself by not telling Arceus about the pregnancy, whereas Zapdos was clearly ecstatic over the idea of having a younger sibling to mess around with. Moltres, on the other hand, slowly but surely entered into a depressed state. Ignoring her siblings when they for once tried to reach out to her, Moltres merely fled, screaming about how badly she wanted to be left alone. A couple of months went by before a heavily pregnant Lugia eventually decided to approach her, this time trying a much more gentler approach than before, and she barely gets an actual reaction from the seemingly emotionless phoenix before Moltres flew into an uncontrollable rage over seeing her mother's current state and attacks the sea guardian head on. In the middle of the one-sided battle, Moltres had accidentally caused her mother to go into early labor, but in her rage she had no idea and just merely assumed that Lugia was faking the whole thing. Only when Zapdos, Articuno, Ho-Oh, and Arceus decide to intervene does Moltres regain control of herself and come to the realization of what she'd just done.
After the egg has been successfully delivered, and after Arceus gave Ho-Oh the berating of a life-time for having not only broken the rule about not having any more children with anyone after the Legendary birds but also having tried to hide Lugia's pregnancy from the rest of the council, Ho-Oh harshly confronts Moltres on the assault of the sea guardian. At the mere sight of the Pokémon that she loved so dearly behaving this way in front of her, Moltres finally breaks down and confesses her love to him while also screeching at him why he couldn't have just chosen her instead of Lugia. Ho-Oh, having finally realized the mess he'd put himself and everyone else in, decides to bring in both Articuno and Zapdos and tell them the truth.
Afterwards, Moltres was not only heartbroken over being so coldly turned down by the Pokémon that she loved, but also sickened at the fact that she'd just tried to seduce her own father into becoming her mate, and this causes her to suffer from a mental breakdown. However, she doesn't get the chance to do anything truly dangerous in her half-crazied mind; a certain individual noticed that something was horribly wrong, and after a kind of messy introduction, said individual has slowly but surely helped Moltres out of her rut.
I don't know yet just exactly where I'll be going with Zapdos and Articuno in terms of story-telling, but I'll probably be thinking of something in the future.
Mewtwo and Mew
Contrary to popular beliefs, Mewtwo is not directly related to the Mew that I'll be using, but rather to another, completely different Mew who unfortunately died some time after he was born. In my fanon, Mewtwo has pretty much the same personality as his anime counterpart, with the only real difference being that he has the tendency to be rather snarky around the other Legends; in fact, to this day most of them are still baffled at the fact that both Darkrai and Deoxys can still stand actually being around him at all with the way he treats them.
Mew, on the other hand, doesn't really change much from the way other people do portray this Pokémon; playful, highly energetic, self-centered, but still having a heart of gold and can actually act a wee bit more mature than usual when the situation calls for it.
After he'd freed himself from the humans, Mewtwo was nearly executed by orders of Arceus had Mew not chosen to intervene just before the Alpha Pokémon could've dealt out the killing blow. After listening to a rather "compelling" argument over why Mewtwo should be kept alive and become accepted into the council of Legends, Arceus finally yielded, but not before giving Mew the orders to supervise the Genetic Pokémon and make sure that he causes no physical harm against anyone. Mew, having personally known Mewtwo's biological "mother" who unfortunately died from the various experiments she had gone through, was more than happy to oblige, seeing this as a way to make up for not having been able to save her. Mewtwo, feeling that his very freedom had been robbed from him, was clearly not impressed with these turns of events. Mostly because of what he'd have to stand afterwards.
Despite this very rough beginning, Mewtwo eventually comes to develop a begrudging amount of respect for Mew. Sure, every time he is confronted about this he'll always deny such allegations, but in the end it's pretty obvious what he truly feels about the smaller feline. And as time eventually passes, that respect eventually turns into love, which he just kept hiding at all times until finally being confronted by Mew in private.
Mew, obviously shocked at first that the larger Pokémon, who's constantly spouted out about how he generally didn't like it, actually has it in him to actually like it, merely tells Mewtwo to wait, claiming that it needed some time to think. A couple of days later, after some very long thinking about whether or not it'd be right to go after its deceased friend's own child in that kind of way, and before Deoxys could try to move in on the emotionally confused Mewtwo, Mew finally gave the Genetic Pokémon the answer he desired.
For a while, the two were actually quite happy (or at least as Mewtwo can get), until Mew finds out about Celebi's feelings for both of them. Mew, not wanting to lose either Celebi or Mewtwo, is obviously confused about what to do, and when Mewtwo finds out as well, the latter is just as baffled about the whole thing. After listening to the kindhearted advice of the self-proclaimed therapist of the Legendaries, Mesprit, and after a lot of convincing, the Mew duo slowly but surely started to seduce the fairy. It never went anything beyond hugs, kisses on the cheek, or a tap (in Mewtwo's case), as neither wanted her to feel like the other person they'd both see on the side. After a couple of weeks, the two finally came open about the fact that they wanted her to become their mate, with Mew trying his hardest to comfort the still-confused Celebi. Once she'd fully calmed down, the fairy looked both of the Mews in the eyes, and gave them her answer.
Her answer?
Yes.
Raikou, Entei, Suicune
Ho-Oh and Lugia
Due to their statuses as trio masters, Ho-Oh and Lugia have a slightly bit more political power than their respective trios. While the trios the masters command over are always welcome to the meetings to voice out their opinions whenever the situation arises, it is really only the masters themselves who are truly needed whenever the trios themselves are concerned.
Ho-Oh is, in short, a jerk. An irrational jerk, if one wants to go into a bit more detail, especially since the Burned Tower incident. He's easily prone to the following things; losing his temper and letting his rage generally getting the better of him at the worst possible times; becoming incredibly jealous whenever someone (unintentionally or not) tries to hit on Lugia (which causes him to fly into another rage); and becoming very full of himself when one compliments his good looks. Oh, and he's also very shallow, and will always go on these extremely long rants about how his point of view is much better than yours, or over why the storms caused either by the Weather Trio, the Kami Trio, or even by Lugia herself, can't be all pretty. Despite that last part, Ho-Oh is not stupid; many times he's shown just how witty and manipulative he can be as long as he doesn't let his rage get the better of him. He's got some generally mixed views on humans; while he does greatly admire and enjoy the pure-hearted trainers that he gets a chance to fight with, it still won't erase the fact that said trainers are so horribly few and far in-between, which just makes him lose faith in humanity. It also doesn't really help that the one human (an immortal human, yes, but human nonetheless) that works alongside the Legendaries while also living in the Hall is the one person Ho-Oh truly loathe and despise with all his being. Also worth noting is that despite his huge temper tantrums, Ho-Oh does have gentle side to himself - it's just that since after the Burned Tower (and before he finally got back together with Lugia), that side of his has rarely been shown around anyone, even to his own trio. One noteworthy relationship outside of Lugia and their children is his relationship with Dialga, as no matter what seems to happen between these two, they've always got the other's back.
Lugia is, in retrospective, nicer than her counterpart. Not much, considering the fact that she's just as willing to hurt someone if they either threaten her young, other Legendaries, or even herself, but in comparison to Ho-Oh she's like a saint. Lugia is usually considered by many who've met her to be a gentle giant, but again - hurt her babies, her fellow Legendaries, or even herself, and you're as good as dead. Lugia has an intense hate/fear of fire, obviously thanks to her many encounters with Ho-Oh (who once wasn't afraid of trying to set her on fire every time they opened their beaks to have a conversation with one another); a mere lighter is enough to make her uneasy, and being in too close of a proximity with more than one of the fire-type Legendaries is enough to nearly make her hyperventilate. As such, her inability to fully bond with either Moltres of Entei might stem from her subconscious telling her to keep a big distance from the fire-types at all times. Despite the fact that she's considered to be "ugly" by some, Lugia does have quite a lot of friends. She's also known for being very adamant about certain issues, issues that'll most likely affect her in the near future.
Ho-Oh and Lugia were originally born and raised in Ecruteak City, with Lugia being the only one who ever bothered trying to find a second home over at Whirl Island. As time eventually passed by, two towers were eventually erected, each on their own opposite site; Lugia perched atop the Brass Tower (aka the Burned Tower), while Ho-Oh perched atop the Tin Tower. Their towers, and the balance they created, was said to be a testament to the balance between humans and Pokémon.
As for the two birds in question, they were very, VERY close. Originally having seen each other as nothing more but very good friends, these feelings eventually grew into love, and the two agreed to become mates. Two weeks after confessing, and one "unusually crazy" night over at the Hall following the mandatory bi-monthly meetings, the two had managed to conceive. Other than the fact that they were still considered "young" by Legendary Pokémon standards, everything seemed to be going just fine.
That is, until an enraged Arceus found out about their little predicament, and ordered Ho-Oh to stay away from the chicks once they were hatched, merely stating that the two birds were "too young" and "irresponsible" to raise them (especially Ho-Oh, who even then was known for having quite the temper). A few days later, Arceus started to push for the law that stated that none of the Legendaries should have any more offsprings (it was eventually passed after the legendary birds were born).
Enraged, Ho-Oh nearly tried to attack the goddess, but is pulled back by Lugia, and is forced to begrudgingly agree to such terms. The two mostly spend the rest of Lugia's pregnancy separated from one another (Ho-Oh in Ecruteak City, and Lugia over at Navel Rock) until the day she delivers the eggs, and Ho-Oh is forced out of his moping by Mew to go see her. The two briefly share a couple of affectionate moments throughout the whole delivery, and once everything is said and done Ho-Oh is forced to leave before Arceus would appear in front of Lugia and the eggs. Both the mother and the eggs are left unschathed, with Arceus promising Lugia that the chicks will earn a place in the Legendary council -- but only if Lugia refused to tell them who their sire was.
For almost an entire year, Lugia had resided at Navel Rock, raising the Legendary bird trio all on her own at least until they're able to fend for themselves. At that moment, Lugia returns to Ecruteak City, where Ho-Oh is still waiting for her, hoping to help her through whatever depression she might be feeling over the entire ordeal. Rather than accepting his advances immediately, Lugia at first tried to stay as far away from Ho-Oh as possible. Only on the day before the Burned Tower incident does she finally smile in his presence, nuzzling him affectionately.
When lightning struck her tower late one night, Lugia fled and left the tower to burn thinking that she was the only one inside, not realising that three individuals perished in the fire, later to be resurrected by Ho-Oh, who blamed Lugia for their deaths. Ho-Oh declared Lugia a coward for fleeing her post, but instead of trying to kill her right then and there, he let her off with a warning; the moment the Rainbow Pokémon finally would find her, he'd set her on fire.
With her roost now gone, and the threat of her now ex-mate looming over her head, Lugia fled to the sea. She'd eventually come across her three chicks while there and become their trio master, completely unbekownst of Ho-Oh having come to regret his wordings but too afraid to seek her out.
As the years went by, whatever good relationship the two birds had detoriated, and they found themselves constantly fighting back and forth. Ho-Oh would constantly snub her both in front of her very face, and behind her back, and would constantly look at her like a bug that needs to be crushed. Lugia was no better, as she'd throw back whatever insults her former mate would deal out, only much more cutting and oh so true. In return, Ho-Oh would physically attack her with his fire, which would serve to further develop her ever growing pyrophobia until their own children would try to interfere. However, underneath all of that hatred, a small part of them still wanted to try and reconcile, but due to their big prides and/or stubbornness to see things the other way around, they refuse to come around.
It was obviously no surprise that at around this time, Lugia tried to search for another mate. Her first few tries were usually met with disaster, either because of the fact that the ones she chose turned out to be not as compassionate as she'd wished them to be, or the fact that Ho-Oh would always try to pull her away from her dates with them in his jealousy. Usually, it was the latter. Realizing that she was only going to put others in even more danger than her abilities to call forth powerful storms, Lugia quickly pulled herself out of the dating world.
That is, until Latios appeared in front of her, confessing his love to her.
Lugia, not wanting to hurt the smaller dragon, merely told him that they could just try it out. However, unbeknownst to her, Latios, being a repressed homosexual who refused to recognize it, was unintentionally using her just to merely convince himself that he wasn't gay. In fact, his negative attitude towards being called gay was so strong that he'd actually try to jump Lugia once he'd found her, regardless of her protests. Eventually, as time passed on, Lugia finally figured it out, but instead of giving him the bitch-slap of his life for just using her like this, she just went along with it - sooner or later, he would spill the beans, and she could just return to being single, as even after she'd gotten together with him she never felt the same kind of love or passion that she once felt for Ho-Oh.
And Ho-Oh? He just merely watched, just shaking his head before he went to hang around with either his Legendary beasts, or with his daughter. Deep down, however, he was seething, but due to a promise that he'd made to never harm any of the other Legendaries over something that just happened to involve his feud with Lugia, he never acted out on that rage.
Then one day, Latios died, having sacrificed his own life to protect a city, leaving behind a grieving Latias. Instead of grieving over the loss of her now deceased "lover", Lugia merely acted calm, only briefly giving Latias a well-needed hug before she'd fled, not knowing that Ho-Oh, after giving the younger Legendary words of condolence, chose to follow her into the hallways.
The two former mates shared a very brief conversation, in which Ho-Oh accused Lugia for wishing Latios dead, including dealing out an insult or two about the fact that she had been used by an insecure homosexual who needed to cover up his deepest desires of a male pounding into him, or that that is all she's been good for either way. Lugia, obviously ticked off at the way the other acted, just merely threw back some hurtful comments to him, saying that if that had been the case, then he must fit any of those categories.
Instead of trying to set her on fire, much like every other time the two have gotten into these kind of arguments, Ho-Oh merely gave her a look of sorrow, before imparting some very mind-scratching words.
Wishing to get away from all of the sympathetic looks both she and Latias got from the rest of the council, Lugia traveled to Orre, where she was subsequently captured by Cipher and turned into a Shadow Pokémon. Most of the things that the actual Shadow Lugia had done in the game pretty much stays the same as in Pokémon XD, but the "rescue" goes slightly different.
After the rest of the Legendary council had discovered her fate at the hands of the crime syndicate, a rescue mission was to be set into action. The two Pokémon that originally were supposed to go to Orre and help the humans turn her back to normal were Zekrom and Yveltal, who were also going to be accompanied by Celebi to see if she could help out.
Instead of letting the three Legendaries do the job, Ho-Oh immediately flew to Orre on his own free will, removing his dampeners and ready to fight his former mate, completely disregarding the orders of Arceus to stay out of this. Once he finally came across Lugia - or "XD-001", as the others called her - a fight immediately ensued. While Lugia was still able to land some pretty decent attacks on him, Ho-Oh still came out the victorious one of the two, but not before collapsing in pain.
Michael, the human who had originally been sent on a mission to bring down Cipher and purifying all of the Shadow Pokémon, had chosen to temporarily capture both of them before heading back to Krane's Pokémon lab. Ho-Oh was immediately taken to a Pokémon Center afterwards, which is where Lugia came to meet him after being fully purified. The two quickly engage in some hostile banter while she tries to replace his old bandages with new ones, especially when he started to complain about her roughness. Lugia, having found out from Celebi that Ho-Oh had saved her on his own will, not forced by either Arceus or by anyone else, merely gave him an off-handed thank you once they'd both calmed down. Ho-Oh, shocked by the fact that she for once had acted a bit more civil around him, merely nodded in return, but neither chooses to say anything afterwards.
After they'd both made a full recovery, both of them flew back to the Hall of Origins, where they were pretty much ambushed by their respective trios - even though Moltres turned all her attention to Ho-Oh and not her actual trio master, causing Lugia to give him a glare.
