Season 3 Episode 3 – Transwarped (Part 3)
Bumblebee is rescued and Sari now has a teenage body, instead of child body.
Five Autobots (Optimus Prime, Bumblebee, Ratchet, Prowl, and Bulkhead) find the fabled Allspark only to become a part of the long-lasting battle between the Autobots and their enemies, the evil Decepticons. A space battle ends up stranding the Autobots in the 22nd century Detroit where they take on roles akin to that of superheroes, fighting both Decepticons and human supervillains. The story takes place in Detroit, and the Transfomers' battle is renewed in this future city on Earth. Instead of being known as the Motor City, it has now become the Robot City due to Dr. Isaac Sumdac's non-alien robotic creations. Sari Sumdac, his 8-year-old daughter, is the main human character that the Autobots saved when they landed on Earth.
Bumblebee is rescued and Sari now has a teenage body, instead of child body.
When the Autobots left to save Bumblebee, Sari uses her Key to upgrade herself to help the Autobots, but soon she loses control of her body, so Ratchet uses EMP to knock her out.
As Sari and Professor Sumdac deal with the fallout of the shocking discovery, the Autobots try to contact Cybertron to warn them of the traitor Longarm in their midst. Meanwhile, Megatron inadvertently stumbles upon a new plan to conquer Cybertron, where an increasingly desperate Longarm/Shockwave tries to cover his tracks.
