W.A.R.S. was the name of one of the Autobot Spy Changers. The Spy Changers are a team of six Autobot espionage specialists. The team can drive over any surface, even water, in defiance of gravity, and have optical camouflage powers that render them invisible at will. Despite their radically different personalities, the Spy Changers are a perfectly functioning unit, often relying heavily on teamwork tactics. His tech spec described him as an aggressive and battle hungry warrior. Heavily armoured, he is a good fighter, but his violent actions unnerve even his fellow Autobots. His Takara tech spec even described him as one of the few pro-war Autobot. (From Wikipedia)
