>>20496095My brain is too tired to work right now and I can't really comment on more recent legendaries.
Lugia/Ho-oh is another metaphor for yin yang (based mostly on Fenghuang the phoenix/the Chinese dragon). Their main aspect may be balance. They may fit under the creation trio for earthly balance sort of thing, and this way they don't clash with the weather 3. Taoism has five main elements instead of three, though, so they were obviously inspired by something else (according to bulba they might have combined various element-birds from different myths and just ran with it --- the thunderbird, the firebird and the arctic bird). The reason why Lugia alone resides above them might have been inspired by the story of a dragon king who had what was basically this giant pole that kept the seas in check, sort of.
Ho-oh created the beasts by merging dozens of dead Pokemon and the reason why they have those three particular elements was (I'm completely bullshitting at this point) that it was its only way of bringing them to life. There might be some other myth here. Anyway, they're all based on non-deity mythical Japanese beasts, apparently.
Celebi is the only time-traveler Pokemon in existence. It paradoxed itself so many times that there are countless Celebi, but there's only one Celebi. Revered as a local god by some people, maybe a minor deity created when Dialga was bored and decided to do something interesting.
The creation trio created Kyogre and Groudon and put the sky above them when the two began duking it out. They also created Regigigas, and Regigigas made the golems. Together the four shaped continents.
Heatran is born out of the heart of a volcano. The first Heatran was born when the earth was created.
The dream duo is below the elves in the hierarchy.
Mewtwo is humans fucking things over.
Shaymin and the Latis might be local, minor deities, Jirachi is a wishing star and one greater god's idea of a joke maybe.
M-Arcanine when?
