I'm glad you picked up on the development of Mike.
Mike started out as a sort of bumbler because that's what he was. Mike really has very little training or skills when this strip started. Over time he's started to learn from his crew who do have training and skills.
The DOC is well grounded in the many disciplines of the physics of the future. He's been around quite awhile and knows a lot more about what's really possible than most of his contemporary collegues.
Yukiro is being a trained med tech has a keen grasp of a persons physical limits and the methods to repair someone when they've gone past them. You know after they've gone splat.
Jet seems to be passing on his own military experience onto Mike. Before having meet Jet it probaly wouldn't have occured to Mike to run practice exercises like Gek and Mike did for the mission they're on now.
Mike seems to be getting the idea of just how connected things are from Gek. The engineering aspects of what he does seems to have its roots there anyways.
I very much intened for Mike to grow into a larger more active role in his own life as time progresses. Even if does mean I have to think about what's going on in more detail.
