The Transformers battle explodes into uncharted territory when the Titans Return! To control an ancient race of giant, city-sized warriors -- the Titans -- the Autobots and Decepticons must harness the power of Titan Masters, smaller bots that give bigger bots increased abilities. Join the battle with Transformers Generations Titans Return Titan Master figures! Terri-Bull is a filthy slob. The Decepticon is one of the most vile bots there is, and he's proud of it. Even though he stinks, leaks fluids, and can't be bothered to clean his armor, other bots know not to call him on it. His mean streak is as nasty as his smell. When Terri-Bull unites with other bots, he gives them the ability to attack other bots with a corrosive rust cloud. Titan Master figures can become the head for any Deluxe Class, Voyager Class, or Leader Class Titans Return figures (each sold separately). This Titan Master Terri-Bull figure converts from robot to head mode and back in 1 step. It comes with a mini tank vehicle that converts to a weapon for Titan Wars Deluxe, Voyager, or Leader Class figures. Choose from Autobot and Decepticon Titan Master characters, unite them with other figures, and power up for battle! Additional figures are each sold separately. Subject to availability.
