A quantum surge rips across the Beast Wars world, altering Megatron, evil genius and leader of the Predacons, into a metal-armored T-Rex. New turbine-powered V.T.O.L. (Vertial Take-Off and Landing) engines extend from his body, providing blazing atmospheric flight and the ability to "drop in" on unexpecting Maximals with his whiplash cutlass! Fused reptilian musculature enhances his power in an organic robot mode. The result: the creation of a supreme tyrant.
