I'm just hoping we get some legendary diversity, even if it means we just have area-specific guardians. A BST 580-600 Pure Bug/Poison/Ground trio would be pretty neat as localized guardians.

Or maybe it will be like the first generation, where there was no real subject for legendaries. They were just there. The used Mewtwo later for a movie, but not much of bigger plan outside of "it was created, it got out of control".

Lulz @ second post. Cresselia is the Lunar pokemon XD

I think matter. Solid, liquid, gas, then an arceus thing that has to do with plasma

Oh yeah and probably a dark regi pokemon because all regis are weak to fighting

Maybe since the games are called Black and White, maybe there could be a legendary representing Yin and a legendary representing Yang.

They made Arceus,aka "God",right?
Why not make a Pokemon whose the complete opposite of him: Satan.
I think that would be great.

I'm with GreySong on this

They had so many legends last time i thought it maght be the end :S

+ With black and white the Yin Yang thing sounds good (Zoruark seems pretty dark and evil (yang)
but i see maybe solar/outer space references with with=>sunlight and black=>night-time or eclipse. These seem pretty easy to implement.

Ive seen an official japanese site about the game... I think its Darkness and light, or divine and arcane... Ya know heaven and hell... I think one of the box legendaries was called Reshihram or something... Oh this is the site: http://www.pokemon-sp.jp/series/bw/ Mmmh yeah... The group avatar pokemon WILL be in gen 5!
