I just feel that Simon's a little... Inadequate, given that he's, like, the most average out of all the other crew. A human doctor from a backwater clinic on Mars field testing experimental technology from a medical company that rules pharmaceuticals in the galaxy. Little training, next to no real field experience.

It all depends on how you write him! I mean sure having a crew of bloodthirsty killers might seem badass, but I find the average Joe type characters in a setting of powered up jerks to be supremely interesting. 

For example, you can play off the disparity by being able to drug the shit out of monsters, or do something relevant while everyone is off fighting the baddie. 

Besides, this is the first step of the journey, I'm sure there'll be plenty of situations that can pop up where your medical skills will be useful (((:
