12화: 괴물 용왕과 아틀란티스 패턴 발견
On Jungle Planet, Overhaul is rescued by Backstop, meets his apprentice Snarl, and plans to bring peace to their world. On Earth, Scattershot reveals he's afraid of being under water, so Optimus says they should just jump in. The Autobots jump into the water, only to find out they have no idea how to swim. Bud gives them a quick swimming lesson. The Autobots locate the Atlantis pattern at the base of an undersea mountain. Vector Prime opens a door there and heads in to investigate with the Mini-cons and kids. Atlantis turns out to be a massive ancient Cybertronian spaceship that crash-landed into the sea. Megatron, Starscream, and Thundercracker have been tailing the Autobots, and soon the Autobots and Decepticons are battling outside the ship. Inside the ship, Vector Prime, the Mini-cons, and kids find the control room. Vector Prime is forced to warp the craft away to keep it out of the Decepticons' hands. The mysterious Transformer Sideways makes his appearance. (Source: Wikipedia)
