When the Autobots recieve a signal from a starship which has entered the Earth's Solar System the owner of the starship is intentified as Wheeljack. Wheeljack is Bulkhead's best friend back on Cybertron. Bulkhead and Wheeljack went on many adventures together and were part of the Autobot warrior fighting group The Wreckers. Meanwhile, Starscream sends a Decepticon named Makeshift on a mission, to pretend he is Wheeljack in order to locate the Autobot Base. When Wheeljack arrives somewhere on Earth he is attacked by Vehicons. The Autobots pick up his signal, once again and Arcee, Bumblebee and Bulkhead Groundbridge to where Wheeljack is to save him. But, Wheeljack defeated all the Vehicons before the other Autobots could help him. Then, it is shown that the real Wheeljack has been captured by Starscream and is held personer. Later, Bulkhead and Wheeljack (who is Makeshift) party. When Bulkhead and Wheeljack play a game of ball they acciently destroy the Groundbridge. Wheeljack asks Ratchet how long it would take for the Groundbridge to be repaired. After, Bulkhead tells stories about his adventures with Wheeljack. To Bulkhead for some reason Wheeljack doesn't seem like himself. Miko takes Wheeljack on a tour of the base. He asks Miko where is the Autobot Base is located. She tells him the correct answer, outside Jasper, Nevada. Bulkhead thinks something's wrong with Wheeljack so he tells him to tell the story about Darkmount Pass. Wheeljacks tells the story correctly, except for one thing he said Bulkhead was there and Bulkhead wasn't. Makeshift's cover is blown and he threatens if the Autobots do anything he'll kill Miko. The real Wheeljack escapes and he defeats some of Starscream's army that he has prepaired on Groundbridge to the Autobot Base. He Groundbridges to the Autobot Base and has a fight with Makeshift. Makeshift loses and is sent back to the Nemisis. Just before he tells where the Autobot Base is he realizes there is a bomb on him and he blows up. The next day, Wheeljack leaves, but asks Bulkhead if he wants to come with him. Bulkhead says no and the last scene shows Miko taking a picture of Wheeljack and Bulkhead.
