Hybrid T-Rex

Hybrid T-Rex is a genetically modified clone of T-Rex because there totally aren't enough variants of T-Rex yet.

Appearance

History
After T-Rex finished filming Jurassic World, the amusement park or whatever it was was left in ruins. They attempted to rebuild, but clearly didn't learn their lesson from the debacle with the Indominus Rex. So, they began working on genetically modifying a clone of T-Rex they had created from his DNA, after T-Rex received an injury during filming. Experimenting with the clone and adding the DNA of various other dinosaurs to the mix, the scientists ended up creating Hybrid T-Rex, whom they though would be an exciting new attraction. However, the process of his creation left Hybrid T-Rex mentally broken, confused by conflicting memories and programming from the scientists. He broke out of the lab he was created in and killed all of the scientists in his rampage, using his flight abilities to escape the island after laying waste to the park and made it to mainland America. He rampaged further, killing everything in sight, until T-Rex, who had seen the attack on the news, showed up to put a stop to his clone. He even called his friend Indominus Rex to come deal with the clone. The two joined forces against Hybrid T-Rex and managed to defeat him after a prolonged battle.

Hybrid T-Rex was thought dead, but he turned out to be alive and the GDF had the brilliant idea of relocating him to Monster Island. He was no less aggressive, and would often fight several Kaiju on the island, including T-Rex himself.

Trilopod Invasion
Hybrid T-Rex was able to let out some rage during the Trilopod invasion.

Trumpzilla vs the World

T-Rex: Final Final Wars: Giant Clusterf*** All Out Attack!
