Mickey is a hot-headed individual that can easily let his temper get the better of him. Shaped by his experiences after the wasteland, Mickey appears to show little concern for other survivors, considering them a risk to his own people's safety, and tends to be rude to them. Said behavior is likely a consequence of the events surrounding his mother's death, in which he hesitated to shoot a raider leading to his mother getting wounded. His uncle was forced to mercy kill her because they didn't have any medicine to treat the wound. Mickey has forgiven Pete just enough to try and help him, but there's still resentment visible whenever they speak to each other. Typically, there interactions come off as mickey acting like a edgy teen. Mickey will often do foolish things, and attempt to gain sympathy so that you don't really blame him. He's not a bad person, just a broken one.

He and Luke are best friends, and went into business together as caravaneers.
