A Sprite Comic on the Bob and George Web site that retells the Mega Man (Classic) storyline, incorporating obscure characters from the Game Boy, PC and WonderSwan games as well as original characters. It starts from the beginning collaboration between Wily and Light, details the creation of two prototypes (only one of which is Super) and Mega Man's battles to bring down Wily. tvtropes webcomics » MS Paint Masterpieces
Just found this by looking up a completely different thing on tvtropes.
It's been around since 2000 and the website never changed its design across the years, and it's actually nice!
