Vance Vetteroy is the Chicago weather man that created S.A.M. in the episode Monster Weather. He ends up causing S.A.M. to go haywire when he uses it to make a rainstorm occur, only for purple lightning to strike S.A.M. and drive it crazy. He later tries to smash S.A.M.'s CPU with a pipe while it's incapacitated to make up for what he's done, only to be captured by his own creation. After Ben makes S.A.M. explode, Vettroy accepts he'll just have to be another "handsome face".
