The Ultra Mode is the state of transformation in which the Rangers handle their Ultra Power. It is the strongest asset at hand to them while in the war against Warstar and is powerful enough to handle most enemies with relative ease, although Vrak, Bigs, Bluefur, Alice and Messenger have been shown on occasion to match or even slightly exceed it and both Rotox and Rico have stood up to it to some extent. The only main antagonists to not face this form are Malkor and Creepox, the most prominent among the Insectoids.
