From Power Rangers Universe

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. 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.

[edit] Dinosaur Mode

Its 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 has often ridden on the back of the Q-Rex as it finished off the enemy.

[edit] Megazord Mode

When the Quantasaurus-Rex transforms into Megazord form, it undergoes several changes in arsenal. Its dinosaur mode back lasers are replaced by shoulder mounted cryo-units, which are used in the Max Blizzard attack to freeze mutant enemies into stasis. It can also fire its left hand in the Q-Rex Thunder Fist attack, similar to an attack used by the Astro Delta Megazord. Its other weapon is the Q-Rex Missile gauntlet located on its right hand. The final attack, of course, is the aforementioned Max Blizzard.
