"Mebius, you're too naive. Only the strongest one will dominate the universe, don't you think?"
"No, that's not the true power you seek.

―Mechazam & Mebius

Mechazam (メカザム Mekazamu) was a robot (cyborg due to Empera's essence) that appeared in Ultraman Mebius Gaiden: Ghost Rebirth. Originally a wandering swordsman that try to seek for an ultimate power, it was later revealed that he is actually a vessel of Alien Empera, named Ghost Rebirth (ゴーストリバース Gōsuto Ribāsu).

He was built after the famous swordsman Zamsher, sharing same traits such as speaking in Keigo and portrayed tsundere-like attitude, even showing a power hungry personality.


  • Mechazam: Toughening Dark Machine (暗黒機靭 Ankoku-ki Utsubo)
  • Ghost Rebirth: Kagemusha Mecha (影武者メカ Kagemusha Meka)



Built by the Alien Empera's forces, Mechazam's true purpose is to become a spare body for the ruler should he died. Since he is created with the technological knowledge of the Empera Army, the warrior possessed the same regeneration technology that the Inpelaizers used, enabling him to constantly self regenerate/repairing himself. As time passed, Mechazam became a wandering swordsman without knowing his past life and his original purpose, bearing the goal to become the strongest warrior in the universe.

A long time ago, a disturbance was detected at the Ultra Zone in the Monster Graveyard, where deceased monsters came to life. The Dark Four Heavenly Kings were revived as well and lead an army of monsters against the Ultra Brothers. Mechazam joined forces with the Ultra Warriors in hopes of finding a challenging opponent but as the battle ended, he disappeared after his wish did not go on as expected.

Ultraman Mebius Gaiden: Ghost Rebirth

The Dark Four Heavenly Kings reunite and make an attempt to revive the Emperor by uniting Mechazam and the Giga Battlenizer. Before they try to achieve their goal they lured Ultras Ace and Taro into a trap in order to blackmail Ultraman Mebius into going in to the Valley of Flames in his Mebius Burning Brave form. Mechazam, who Mebius meet minutes before and had saved Mebius before this, and wanted to understand why Mebius would risk his live to save "comrades" and goes with Mebius into the Valley of Flames to retrieve the Giga Battlenizer. Seconds after entering they are confronted by EX Zetton. After a short scuffle with the guardian, Mechazam and Mebius were able to retrieve the Giga Battlenizer and destroy Zetton but the mechanical being sacrificed himself to save Mebius from a falling magma. Mebius then took Mechazam back to the surface, they were then attacked by the Dark Four Heavenly Kings, and Ultraman Hikari (whom had seemingly betrayed them earlier). Mechazam then died due to his wounds but was revived by Alien Mefilas, who reawakened his true potential as Ghost Rebirth.

When all seemed lost Hikari freed Ace and Taro revealing he "betrayed" the Inter Galactic Defense Force to get close enough to the Dark Four Heavenly Kings so Mebius would have an ally when the time was right together the four Ultras defeat the Dark Four Heavenly Kings, but Ghost Rebirth was still active after a long struggle until Mechazam's true programming resurfaces. A dying Mefilas took this chance to shove the Giga Battlenizer, starting the revival process. What left of the real Mechazam begged Ultraman Mebius to destroy him so Empera would never return. Followed by the explosion of the Burning Mebium Dynamite, Mechazam's Sword Zamber left intact, standing still as if it was his own grave marker.


  • Voice actor: Hideyuki Hori, Koji Kawakami (Super Hero Generations)
  • True to being the revival apparatus of Alien Empera, Mechazam shares the same height and weight as the former ruler himself.
  • Mechazam's original design is actually revealed to be that of Alien Empera and was originally named Inpelaizer Ghost but Bandai demanded him to be based on Zamsher, due to the initial design is based on a samurai. Of course, his cold traits (which resembles Zamsher himself) is something coincidental.
  • Although claimed to be a robot, his possession of Alien Empera's essence made it clear that he is a cyborg, to the point that Empera's clothing envelops his body during the dark emperor's rebirth.
  • Due to his true nature as Ghost Rebirth (Empera's minions), he had a role as a pure villain in Ultraman Festival 2009 as one of the villains sought to revive Empera. At the end of the stage-show, his transformation into Mechazam in the stinger was meant to promote the Gaiden he appeared in.
  • His suit is finally converted into Renki (Guren Equestrian) in Ultraman Orb. Interestingly, Renki is in fact a ghost.
