|Episode:||A Line in the Sand|
|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.
- Tankenstein's boots were later recycled for the alien criminal "Parsnippity" where it was combined with the head of Deviot and the body of Mirai Sentai Timeranger villain Boribaru (unused in Power Rangers Time Force).
