Thought I'd share what I have for my character concept as of right now.

As I said earlier, might as well make a gangster. So meet Croaks. Not his real name, but that's what everyone who knows him knows him as. Croaks is part of a riverside gang, operating in one of the many slum zones and making a living out of drowning informants, making strikes at ferries (mostly public transport), hiding evidence, what have you. The Amphibians isn't a large group of people, but they do have a good spot for themselves and they've been entrenched for a good while. Not the least thanks to Lt. Davison's combat supplies.

Now he and his brother from another mother, Ribby, have come across a problem though. No more stuff. And with their little numbers and dwindling ammo counts, that's going to add up to a disaster. So better get a move on.

Which is to say, anyone who might be interested in the role of the other gang guy should bring it up with me. That could be an interesting brainstorm session.
