Biff was one of the first members of GLADIUS Squad. A born leader, Biff was slightly frustrated when Caesar was put in command of the squad. But he still is in command of the 2.0 half, so he is (usually) satisfied. His alpha male personality often puts him at a disadvantage, overlooking or missing opportunities while trying to prove that he would be a better leader than Caesar. This and his short temper make him the perfect agent and public figure for his squad.
Sorry about the bad lighting, my camera settings were all messed up.
