S.A.M.

From Wikitrix

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 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 SAM gives off. S.A.M. appears in "Monster Weather".
