Created by Elsa from the Ruby Dragon card which is part of the game called Dragon War, and the most powerful card. Unfortunately for Ethan, Principal Randall takes the card from him, when she catches him and Devin playing on school grounds. As Elsa, she uses the Geno Randomizer to bring the Ruby Dragon to life. The Ruby Dragon's first mission is to defeat Trent, then he battles the other Rangers. The White Ranger shows up to take him down, but the Ruby Dragon knows Trent's keeping Mesogog's true identity from the other Rangers. The Ruby Dragon uses this to his advantage, but the Power Rangers are able to come together and defeat him with the Z-Rex Blaster, Super Mode. It takes the Thundersaurus Megazord, the Mezodon Megazord, and the Dino Stegazord's combined efforts to destroy him completely.
