|Voice Actor:||Derek Stephen Prince|
Tankenstein was a powerful shapeshifting mechanical entity used by Astronema. He was a humvee that tracked down and hunted the Power Rangers. When it found them, it ran them over and teleported them to a desert, resisting their blasters and weapons. It found a formidable opponent in Zhane's Galactic Rover, who destroyed him.
Astronema then ordered the Satellasers fired, and Tankenstein reconstituted. When grown, he took a robot form and the Mega Voyager jump-punched Tankenstein, took his sword, and stabbed him in the face, causing him to grab the Mega Voyager and lift off high above the city. Tankenstein exploded in a massive fireball in the sky, taking the Mega Voyager with him. The Mega Voyager was destroyed, however the Rangers managed to survive.
- Unlike its Sentai counterpart, it isn't created from the main villains ship.
- Unlike its Sentai counterpart it is not a mecha that is operated by someone, but rather an actual monster that is able to speak.
