Gary Mitchell, Kirk's broheim from Starfleet Academy. Mitchell appeared in only one episode of Star Trek, Where No Man Has Gone Before. In it, he gains god-like powers after the Enterprise passes through the galactic barrier. Basically, J. J. Abrams is adapting an entire episode from The Original Series into a movie.
accidentally revealing this during an interview with SFX Magazine. I have no problem whatsoever with Abrams adapting more TOS episodes to the big screen. Keep going.
