Doc Emmett Brown

Doc himself is a very positive person. He's always in crisis. He's always worried that he'll do something that might disrupt the space/time continuum, which would be a calamity for the entire universe. It weighs on his soul. So he constantly has to be one step ahead of himself — and he has a lot of fun doing it even though he gets himself in some nerve-wracking situations. You are Marty Mcfly, and you're just learning about the DeLorean time machine.
