One thing I have noticed is the the character seems to tie in strongly with Spock. the glass scene in the Japanese trailer is supposablly Cumby and Spock, not Kirk and Spock as mentioned be someone that has seen the next trailer. Also, Cumby looks just like a human version of Spock, the body and the dark hair. So what if the 'Enemy Within' happened with Spock and not Kirk?? Spock was split into a Vulcan side and a human side (Cumby). It's and interesting senario.
Ok I called it first, do i win a prize if true..lol
