Tankenstein is a powerful shape-shifting mechanical entity used by Astronema, he serves as the primary antagonist of the penultimate episode of Power Rangers in Space " A Line in the Sand". 

Excluding the three minor monsters that appear in the two-part series finale episode of Power Rangers In Space and the entire Zordan Era, "Countdown to Destruction", he is not only the final monster Astronema sent to fight the Power Rangers, he is also the final monster of the entire Zordon Era as a whole.

Character History

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 with its energy beam, resisting their blasters and weapons. It found a formidable opponent in Zhane's Galactic Rover, who destroyed him by ramming straight through his side..

Astronema then ordered the Satellasers fired, and Tankenstein reconstituted. When grown, he takes a robot form and the Rangers summon the Mega Voyager to battle this monster, it is more powerful than any monster to be fought by the Rangers and he badly damages the Mega Voyager, but with the last of its strength, it jump-punches Tankenstein, takes his sword, and stabs him in the face, causing him to grab the Mega Voyager and lift off high above the city. Tankenstein explodes in a massive fireball in the sky, taking the Mega Voyager with him. The Mega Voyager is destroyed, however the Rangers managed to survive.

In his Humvee form, Tankenstein doesn't have much in a way of personality, only speaking in motor roars.

In his Robot form, Tankenstein is shown to be an arrogant droid who likes to boast how "invincible and powerful" he is, and thinks that he can not be stopped by the Power Rangers. He was also shown to be impatient to a fault  as when the Rangers finally landed one good hit, rather than see the battle to its end, despite the fact he was winning, he immediately grabbed the Mega Voyager, flew into space with it held captive, and self-destructed with the intent of killing the Rangers (who survived, even though the Mega Voyager didn't).

Powers and Abilities

Being the final monster that Astronema summons, Tankenstein is one of the strongest monsters in Power Rangers in Space, and is one of the strongest and most powerful monster in the entire Zordon Era, he posses far greater strength then any of the monsters fought by the Rangers before hand, and can easily stand up to the Mega Voyager.

Behind the Scenes


  • Tankenstein is voiced by Derek Stephen Prince.
    • His voice is almost the exact same as Elgar and Staroid . His voice sounds identical like Staroid (who already sounded like Elgar) but with a heavier echo effect added.


  • Tankenstein is very similar to Goldgoyle, as they're both the final monsters to be summon by the main villain of that show, have arrogant personality of how strong they are, both monsters have jet thursters under their feet, both monsters have firepower, both have the ability to launch electrocution cords from their shoulders. Their also adapted from Sentai villains who would be the last opponents against their respective Sentai foes for the season, while in Power Rangers, they are the Final-Monsters-of-the-Week, albeit, stronger ones.
    • Despite their similarities, they are opposite in some way.
      • Goldgoyle is a living monster with only one form, lacks any weaponry, has lighting beams for firepower, can absorb his enemies' attacks, manages to defeat not one, but two megazords at the same time and is defeated by the Rangers' weaponry.
      • Tankenstein on the other hand is a mechanical monster that has two forms, has weaponry, has lasers for firepower, does not have the ability to absorb his enemies' attacks, only defeated one Megazord and actually self-destructed himself.
  • Unlike his Sentai counterpart, he isn't created from the main villain's ship.
    • Similarly, he is not a mecha that is operated by someone, but rather an actual monster who is able to speak.
  • Tankenstein name comes from the words Tank and Frankenstein.
  • He also sounds similar to Elgar as Derek Stephen Prince provides his voice
  • Tankenstein's boots were later recycled for the alien criminal Parsnippity in Power Rangers S.P.D., where he was combined with the head of Deviot and the body of Mirai Sentai Timeranger villain Boribaru (unused in Power Rangers Time Force).
