T-rex is an anjanath and Krim's pet. He has purple skin and fur and small yellow eyes.

T-rex lived in the baroness desert. He is first seen being attacked by a territorial barroth. When Krim is separated from the Rangers, she single handedly attacks the barroth and saves the purple dino-looking creature. At first, T-rex is aggressive towards Krim but later calms himself after realizing she had saved his life. The anjanath bonds with the young elf and assists her in returning to the other rangers.

T-rex has powerful jaws that allow him to lift up large creatures and throw them around and even rip apart foes, along with a powerful nose used for smelling out prey. He also has the ability to breathe fire from his mouth utilizing an organ in his throat. He is a relentless predator that will chase down anything that dares attack him or his friends. Once he's been provoked, T-rex won't let an enemy get away easily. When enraged, T-rex will breathe heavily and reveal his nostrils. He will also occasionally flash small fins from his back in an effort to threaten his target, making him seem larger in appearance.

T-rex a prideful, but mischievous, anjanath. While he is cool-headed, calm and quiet, he is also hotheaded, fiery and aggressive. He does have a sense of humor, as he laughed at Quark stumbling off Ice Blister's back in an attempt to ride him.
