The Autobots are upgrading their security system while the Dr. Fujiyama asks the Autobots to attend the unveiling of the most technically advanced robot ever built by man and to protect it from the Decepticons. Optimus Prime agrees and the Autobots attend the unveiling, though Wheeljack and Ratchet doubt how "advanced" a robot built by humans could possibly be. During it´s presentation to introduce Nightbird, the Decepticons attack and steal her. At a temporary base of the Decepticons, Bombshell brainwashes her to obey Megatron, who sends her to infiltrate into the Ark and steal the World Energy Chip; a database on all the world's energy resources.
The Autobots tries to stop her, but due a promise with DR. Fujiyama, they can´t hurt her. Due her performance, Megatron considers her to replace Starscream, who freaks out and Megatron tosses him into a cage. The Autobots finally stop Nightbird with an energy field, but the Decepticons come to rescue her and the World Energy Chip. Starscream escapes from his cage and sneaks into the battle. He blasts Nightbird with his null ray and the Autobots recover both her and the energy chip. Angrily, Megatron and the Decepticons chase after the traitorous Starscream. The Autobots return Nightbird to Dr. Fujiyama, who seals her away in a metal coffin, vowing never to reactivate her. Inside the metal coffin, Nightbird's eyes glow and appears to still be functional as she is sealed.
