Tyrant the Tarbosaurus is an evil tyrannosaur bent on world domination and is an enemy of The Velociraptors, he's also their equivalent to Dr. Blowhole.
As a tyrannosaur he is large, by about 46 feet, though as a tyrannosaurid he has puny arms with two fingers but they are stronger than they look.
He is the leader of a cult comprised of robotic dinosaur soldiers.
Tyrant is power-hungry and is willing to commit any form of villainy to satisfy his quest, but unlike most villains he understands forgiveness and doesn't mind failure very much, even if his subordinates feel that they deserve to be punished.
He has been the archenemy of the Velociraptors for decades but doesn't feel like he'll ever defeat them.
