Am I the only one who gernuinely thinks Arceus is supposed to be an all-powerful, yet benevolent god? Even the fight that we never see strikes me as "You, who would dare make an attempt to capture me… I accept your offer. Best me in combat, and I shall bless you with my presence" or something like that.

Wish the anime didn't take the piss out of him, like it does with ALL the good damned characters/pokemon, in favor of that shitlord and his dumb half-developed rat.

I think Anime!Giratina is a nice subversion of a traditional satanic archetype, though. Not evil and even tolerant of trespassers (Graceland and Zero's early expeditions), just very much not a fan of its siblings wrecking shit and not cleaning up after themselves.
