He was created by Seth using a fossil of a Tyrannosaurus stolen from a dig site in Full Scheme Ahead, and had been revived by the end of Tricks of the Traitor. In One Final Move!, he was unleashed on the D-Team's city. He withstood Lightning Spear and Volcano Burst without being affected, forcing the D-Team's dinosaurs and Terry to retreat, but Seth called him back because his energy was running lower than expected after the test run. Seth supercharged him using the Stones from the D-Team's Dino Holders and set him out against the D-Team and Alpha Gang again after Saurophaganax's defeat.
