Still don't know the details, but I sort of called it. Around Generation IV, I was working on fanart for something I made up called "Tetra Pokemon" (tetra- meaning "four"). They were a fourth (or technically third) evolution stage that gave weak fully-evolved Pokemon a chance to rank evenly with the more powerful ones. They are event Pokemon that are caught in the wild at lv. 100. Coincidentally, Ampharos and Blaziken were part of my fanfic. Never got around to making the artwork, though. NOW I WANT POKEMON Y!!!!!!
