The Nemesis Crew was an army of Decepticons stationed aboard the Decepticon warship Nemesis who unanimously serve to their master; Lord Megatron. They serve as the main antagonists of Transformers: Prime.
The crew was initially formed after the fall of Cybertron, with Megatron rallying his armies to board the Nemesis to intercept the Autobot Ark and destroy it.
The Nemesis eventually managed to catch up to the ship and the Decepticons stationed aboard attempted to board the Autobot ship. However, their battle was interrupted when both ships entered a black hole, resulting in the Autobots and Decepticons being split up.
The Nemesis Crew eventually found its way to Earth, hoping to conquer it and kill its native inhabitants. However, they were opposed by the Autobots and their human allies.
Later, while the Autobots were battling against Unicron, Starscream attempted to retake control of the ship with Knock Out and several Vehicons. However, they were defeated by the Autobots, with Starscream being betrayed and knocked out by Knock Out, who joined the Autobots soon after.
