I want to see what the other characters are like once we get posting. My main goal is interaction. In the future he'll either grow up and/or die. I haven't decided which.

Primary Role: Annoying Horse Man who makes a lot of sarcastic comments who pretty much keeps the ship Running. Perhaps a Horse A.I at some point. Marking is more off to the side I think. 
Honestly I see him as a bit of a dick. He's had a rough life. And he's part horse.

That's a jumble of info but it's what I have laid out for him.
