The Chimera of Greek mythology which is where these types of dinosaur's name come from.

The Chimera dinosaurs is the name given to a huge amount of dinosaurs that are created when various mutant dinosaurs merge together to create more powerful beings alongside much more ferocious beings.

Although Firroth's allies and enemies are largely dragons and other reptiles such as alligators, he also is made to defend Earth from dinosaurs which are not related to these types of dinosaur.

The Chimera which these dinosaurs are based on are the second Greek monster on this wiki alongside the Hydras in Defenders of Earth.

Legend of the Chimera

The Chimaera was a hybrid monster in Greek mythology, child of Typhoeus and Echidna and sibling of Cerberus and the Lernaean Hydra. It had the head and body of a lion, as well as the head of a goat that was attached to its back, and a tail that ended on a head of a snake.

It resided in Lycia, a place in Asia Minor, where it ravaged the lands with its fire breath. It was killed by Bellerophon, assisted by Pegasus, when the former was asked by King Iobates of Lycia. Bellerophon rode on Pegasus' back, who could fly, and shot arrows at the Chimera from above.


The name of the species as they are described by the Space Fleet comes from the Chimera monster from Greek mythology and the dinosaurs here are called Chimeras because they have merged with other dinosaurs to become more powerful.

Unlike the dinosaurs however, the only chimera dinosaurs shown are on land and in the air. Also, these dinosaurs are almost always hostile to humanity and are carnivorous just like the animals that hostile aliens and dinosaurs are based off.
