Can we get a headcanon thread going? I've had something running through my mind recently

Pokemon war mentioned by Surge was between Kanto (or all of the Japanese regions) and Unova (or any other US based regions) a la WWII. Maybe Kalos was in there too as an ally to Unova, but the kicker here is mewtwo. I'm into the idea that maybe it was some sort of weapon of mass destruction attempt gone horribly wrong. Maybe there were bombings too, and they resulted in, i don't know, the sevii islands. This could be fleshed out quite a bit, i reckon.

Anyway, i'm sure the buzzwords will come out here but it's all in good fun, lads. What're your autistic stories made up in place of logic?
