[@The Jest] Just as you mentioned space pirates I thought of John Silver from treasure planet. My character is heavily inspired from him although his bio and personality are original and believe it or not I always write a new bio for every new character I make.
I used the weapons that he also used in the animated movie since it wouldn't feel right to play any other ones, it would lose the feel.

Edit: I vote for Pirates! Stay true to the title of the RP!!!
