The Dinobots are several teams of characters in the fictional Transformers Universe. The groups are made up of several robots, each of whose alternate mode are those of dinosaur or similar prehistoric animal. Called Dinotrons in the Japanese version, they are once more called in the Japanese dub of Transformers Animated.
The Dinobots are a group of five Transformers, part of the Autobot faction. Their exact origins and abilities vary from one version of Transformers to the next, but they are always exceptionally powerful Autobots, able to sustain heavy damage and wield heavy firepower against their foes. In all media, they are depicted as being fiercely independent and liable to break away from the main group of Autobots when the mood takes them. They are also the only known group of Autobots that can fly in robot mode very much like most Decepticons.
Due to their unique alternative modes, their memorable personalities and their fighting prowess, they are fan favorites in their cartoon, comic book and toy incarnations.
The creation of the Dinobots was almost happenstance. One particular day at Autobot Headquarters, the Autobots detected unusual seismic activity from within the walls of the cave. Ironhide investigated the disturbance and found the fossilized bones of dinosaurs. After researching more dinosaurs, Wheeljack made the suggestion that, because of their brute force and power, dinosaurs working for the Autobots would shake up the Decepticon. Ratchet agreed, suggesting robotic forms and Optimus Prime authorized the project.
