The Nemesis

The Nemesis is the Decepticons' immensely powerful battleship armed with heavy weaponry against the Autobots from the Transformers franchise. Headed by the giant robot dictator, Megatron, the Nemesis has been portrayed in many different ways over the course of the Transformers fiction.

In the original cartoon, the Decepticons jump into the flagship and chase the Autobots down through space, who are piloting the Ark. The Nemesis is lost once the Decepticons board the Ark as it crashes into Earth. In the Cybertron games, the Nemesis is actually the Decepticon Trypticon in a comatose state programmed to permanently stay in his vehicle mode. This was done both to help the Decepticon catch up with the retreating Autobots and to punish Trypticon, who was a complete failure despite his power in the first game. In Prime, the Nemesis serves as the Decepticon's main base of operations and in Revenge of the Fallen, it is crashed into a unidentified moon, acting as both the currently weakened Decepticons' only safe location and their younglings' hatching grounds.
