uhh...because Fire-type starters evolving is morbidly cliched and shows that the anime is dying for ratings?
It's not necessary. Frankly, part of me doesn't want it to happen so that, when it doesn't, I can rub it in like a prick. Because frankly, I hate Fire-type starters. Chimchar's interesting at least, but doesn't need to evolve. If anything, it skewers any interest built into it because it becomes a case of "liek omfg it evolved it's so flippin' awesome and liek wh0@ because fire starters are the shyte and should all be fully evolved because fire is such a BAMF type. then it should be in liek every battle because it's so effing boss and when it isn't, all us n00bs moan and whine because that fugly grass starter or that other pokemon, who's liek soooooooo weak because they're not fire-type, actually DID SOMETHING FOR ONCE, and god forbid any of ash's pokes besides his fire-types DO SOMETHING, OHLAWD WHATEVER SHALL WE DO."
