Mega Man

Kills bosses and uses their power. Knows how to charge Atomic Fire, the Mega Buster, and a few other weapons.

Capcom has put Mega Man into many game series, and they build off each other by harnessing the power of sequels. The least successful series is the sports one(you think Battle and Chase is bad? Try Mega Man Soccer!). Some players prefer the old school games (Mega Man, Mega Man X) to the new ones (what the hell IS the new stuff).
