Doomtron
From Power Rangers Universe
Doomtron is an evil giant robot created by Frax. It is also powered by Frax, who is able to board it and control Doomtron.
Doomtron's energy comes from a Trizirium crystal, which is kept inside Frax when he is wired to Doomtron's systems. Doomtron proves a hard Robot to defeat, as he beats the Q-Rex Zord in battle and wreaks havoc across the city, opening large vortexes in the sky, until the Time Force Rangers are finally able to Neutralize Doomtron's crystal and destroy the robot.
