Transformers Animated

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 mid-21st 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.
