description to be added
A robotic T-Rex monster created and piloted by Moltor. It can bite, shoot lasers from its cannons, and it also has the ability to launch swarms of Lavadactyls. Moltor asked the Fearcats for a gyro to power it, but the gyro somehow doesn't work. Then Moltor and the Fearcats plan to capture Ronny to drain her energy as an alternative power source. Once powered, it proves itself powerful enough to counter attack and defeat the DriveMax Ultrazord. It was running out of power as the Battlefleet Ship appeared and Moltor retreated. During the second fight, it was easily destroyed at hands of the Battlefleet Megazord.

The zord can fire an assortment of blasts from its cannons and mouth. It also has incredibly durable armor powered by one of Flurious's Gyros, allowing it to take a beating from the Drivemax Ultrazord.
- The Cybernetic Rex resembles the Quantasaurus Rex from Power Rangers Time Force, the reason for this is because Cybernetic Rex's Boukenger counterpart, Evil Mechanic Dragon Grand, as with each primary antagonist and each individual monster of the week was visually designed as an homage to the various robots and other mecha piloted by the protagonists of the 29 previous Super Sentai Series (except for J.A.K.Q. Dengekitai), as Boukenger was the 30th anniversary series. Evil Mechanic Dragon Grand's look was based on the Quantasaurus Rex's counterpart, the V-Rex of Mirai Sentai Timeranger.
