cyber professor

First-round of sketches of the character for a fighting game. his name is the professor, he is half man, half cyborg, anabolic musculature, the brain flows inda a transparent container, one hand is a mechanical prosthesis. That's it, no story behind, either background, no style of martial arts. IMHO it is not cool design brief at all, and not a good way to create video games.

My ideas: transparent tank is too fragile, have to be protected somehow (hide into body, have additional bumpers and etc), why he has such name? Probably he was a professor before, or the shape of the cover of his container reminds someone of a professor's hat, or he has a photo of Einstein stuck to tank with his brain. How chassis could very on his fighting manner. What if his hand have a lot of tools for R&D behind the heavy armor? Here is what I've got after answering for all those questions :)
