A deceptive robot monster created from scrap parts by Klank and Orbus. He was to make friends with the Power Rangers, aiding the Rangers on Earth with different situations. He even saved a little girl's dog from being run over by a car on the street. Later, King Mondo and an army of Cogs and Quadrafighters launched an attack on the Rangers and Defector. Klank then arrived to cause pain to Defector with a remote control. Rocky went to check on him, and he responded by attacking the Rangers. Rocky then went on the attack, and soon afterwards Tommy called on the Defender Wheel. Rocky, who felt responsible for the whole thing, volunteered to pilot the Defender Wheel, destroying him.
