Sorry for taking so long with updating this carp.
This is Mister Malkin, AKA Catboy, Kyle Whyte (AKA Speed)'s partner in crime fighting.
Catboy's memories aren't all...there, he remembers that a scientist combined his body, mind, and soul with that of a cat, and as such, he has very few memories from before the incident, but what he does remember is a combination of the memories of the Cat and the Boy.
He remember's the boy's surname was Malken, but he doesn't remember the boy's first name, and as such, tends to call himself by a new name everytime he introduces himself to someone in his human form (pictured to the right)
This image depicts him way back when Kyle was Speed and the two fought together as a team, and way back before I remembered that he was supposed to have a tail before he became BA, back when he was adorable.
His superpowers consist of the ability to change from his natural form to near fully cat or human, as well as the fact that, in a way, he has a type of immortality. As long as he doesn't die from natural causes or suicide, his consciousness and abilities will be inputted into the nearest cat, this process gives him a maximum of nine lives, as evident with the semi-cat test subjects before him.
He eventually becomes BA, but let's just enjoy his period of innocence while it's here.
He is currently on his first life, and is a tabby cat, his spandex suit-thingy is green, as is the hat he wears in his human-y mode.
