Vance Vetteroy

Vance Vetteroy is the Chicago weather man that created S.A.M. in "Monster Weather". He ends up causing S.A.M. to go haywire when he uses it to make a rainstorm occur, only for 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 have to be just another "handsome face". Vance Vetteroy has only made one appearance in the Ben 10 Series.
