Tunnel Rat is a member of Sigma Six. He really loves being a part of a team, especially his role which is infiltration and sabotage. He loves the thrill of being somewhere he's not supposed to be, something he experienced as a child sneaking into rated R movies. He's well versed in mechanical and electrical engineering as well as plumbing. He learns a lot from the things he has to destroy. Occasionally he is so awestruck with the ingenuity of an opponent's contraption that he will leave a note for them to tell them how much he respects them and what they might improve in the future so he wouldn't be able to destroy it. He writes these notes on his wrist-integrated labelmaker.
