S.A.M.

S.A.M. is the name of a villain in Ben 10. S.A.M. appears in'' "Monster Weather". ''

History
S.A.M. is a robot designed to help the local TV weatherman, Vance Vetteroy, with his broadcasts. His name stands for Sounding Autonic Meterograph. Vance attempts to redesign S.A.M. in the hopes of giving it control over the weather, not just report it. During the test run, S.A.M. is struck by purple lightning and develops a somewhat HAL-like personality, albeit with more emotion. For some reason, S.A.M. decides to use his new abilities to wreak havoc(why is never explained, though such events would certainly be newsworthy). Ben is able to take S.A.M. offline with help from Grandpa Max and Gwen by using a sound frequency at the end opposite of the spectrum from the hum S.A.M. gives off.

Water Form
The Water Monster is an entity that is created S.A.M. When S.A.M. first created it, it caused a torrential downpour at the concert. He was turned to steam by Heatblast.

Cloud Monster
Another form of S.A.M. is the Cloud Monster, a thunder cloud. When S.A.M. first created it, it reigned down thunderbolts all over the city. He was shorted out by salt.

Different Elements Monster
S.A.M also turned into a monster made up of different weather entities and had Vance Vetteroy trapped on him. It was his final form before being destroyed by Fourarms playing some electric guitars.
