The character is an engineer in a dystopian futuristic world. He isn't physically strong and is initially shocked to be chosen for a space colonization mission. As players conquer more planets, he grows from being terrified to being more confident and determined.

Think "anxious-but-brilliant". He has a bit of that frantic, high-energy Shaggy (Scooby-Doo) quality, but he needs to sound like a real person surviving a dystopian world, not a caricature. I'm looking for a collaborator who wants to "own" this character for the long term.
