Mega Man's 'sister' Roll. In the classic series and all other media, Roll was built as a robot after Mega Man, but in my retelling, she will be a human.
Possibly my favourite Maverick from Mega Man X 6, Infinity Mijinion is actually based on a water flea. His abilities in the game consist mainly of lasers and cloning himself. The battle itself would get extremely frustrating because there were SO many copies of himself, I feel he would make a great TV show villain!
