Full list of appearances
The Quantasaurus Rex, often called the Q-Rex, is the individual Zord of the Quantum Ranger. Originally a prototype Zord from Time Force, the Q-Rex was one of the first objects to be sent back in time, but it was lost in time during the Jurassic until recovered by Wes and Eric. Like the Dragonzord it can be controlled remotely, unlike it however it does not seem to have a cockpit
It is powered by Trizyrium Crystals, a technology developed in the future and manufactured from what is considered industrial waste today. Due to its unstable nature, it can often go berserk and out of control as Eric soon found out. The Q-Rex continues to serve Eric.
During the final battle against Doomtron, due to both having Trizyrium Crystals, it caused time portals to open up. During the last part of the battle, Wes, now in command of the Q-Rex due to having the Quantum Morpher, was able to neutralize its crystal to close the portals. Despite this, the Q-Rex still possessed enough power to destroy Doomtron, showing that it apparently possesses more than one power source.
For the past 12 years, Time Force kept the Quantasaurus Rex in safe keeping until the time had come. During that time period, Quantasaurus Rex was torn apart and redesigned into the Q-Rex Drill.
Dinosaur ModeIts main weapons in dinosaur mode are the Q-Rex Lasers on its back and a giant laser that fires from its mouth. The Time Force Megazord in Mode Red once rode on the back of the Q-Rex as it finished off the enemy.
