Gene Zaroothian, a former bounty hunter found in Blim City, is homeless and had lost his legs before the game begins. He offers you his bounty hunter suit in exchange for your house, which you accept, and stays on the couch in your house for the rest of the game. Gene is also a little bit more of a dick than most of his peers, as he is constantly trying to get you to help him out. This is a good thing, because you are not the type of person who will just sit back and do nothing, but you will help Gene out, no matter how much of your time he takes. You will not be able to do this all of the game time, however, so you should try to make the most out of every moment you spend with Gene, especially in the beginning of this game, when you have no reason to trust him. If you do, then Gene will be very helpful.
