This is Serge. Hopefully he looks a bit more like an armadillo as opposed to earlier attempts - that shell is a tricky thing to curve around his form from different angles. Bonus Internet points to whoever can say how he fits those clothes on inside the shell x)

I'm still playing around with the -roll- he's going to play, but one idea is he's stationed in a soldier's port town which serves as a hub for both naval and ground forces. Because of the population of skilled fighters, tournaments are common and one can make a decent enough living by simply providing entertainment and working the odds in the arena. Serge excels in hand-to-hand combat, often blocking or deflecting blows with his natural armour, then rushing in and retaliating with those huge backscratchers he's got!
