"It's finally my turn. I'll defeat Ultraman Mebius head on and show him what true strength really is. I'll offer Earth as a gift to the great emperor."

―Grozam, The Immortal Grozam

Grozam (グローザム Gurōzamu) is an Alien Groza and was a member of the Dark Four Heavenly Kings and is one of the antagonist of the penultimate arc of Ultraman Mebius. Self-proclaimed as the "Immortal Grozam" (不死身のグローザム Fujimi no Gurōzamu) for his regenerative factor, he served Alien Empera as the ruler's Battalion General (豪将 Shōgo).

Pre-Ultraman Mebius

Grozam and Deathrem were long ago participants of the Ultimate Wars as part of Alien Empera's army. During that time, the two were accepted into a group called the Dark Four Heavenly Kings, although their fourth member were expelled by Empera for his rebellion.

Ultraman Mebius

In the present day, the Dark Four Heavenly Kings were joined by Yapool, who took the fourth place and succeeded their former member Ark Bogarl. Glozam was incapable of believing this, until Yapool silenced him by threatening to turn his fellow members into Terrible-Monster under his servitude.

Following Yapool and Deathrem's defeat, Glozam offered his turn to perform. In oppose to the former two's use of mind games, he prefers heading against Mebius face-to-face in personal. He froze the dam of Takakura City to lure and challenge Mebius. Facing the Ultraman at the nearby dam, Grozam displayed his ability to regenerate, resisting against Fire Windom and Mebius Burning Brave easily before pinning the latter to the dam and froze him. Confident in his victory, he broadcast it to the citizens before vanishing.

Returning to the base, Mefilas warned him that even if Mebius frozen, he is still alive and that the Ultra Brothers and humanity can rescue him. While assuming humans as small hindrance, his encounter with the Ultra Brothers would be easy with his regenerative factor. The next day when GUYS tried to rescue Mebius, he stopped them in the middle of the progress until Seven delay him enough for Marina to revive Mebius. The two Ultra Warriors blow Grozam into pieces but like before, he regenerated himself again until Konomi used the Maxwell Tornado to trap him within a gigantic tornado of super-heated air, vaporizing the regenerating alien and ending his twisted attack on Mebius and the Earth.

Ultraman Mebius Gaiden: Ghost Rebirth

The Dark Four Heavenly Kings

Several years passed since the death of the Dark Four Heavenly Kings and the destruction of Alien Empera. Grozam remained in the legendary Monster Graveyard until he was revived with fellow members of Heavenly Kings.

They lured Mebius, Ace, and Taro to the graveyard after capturing Hikari and set a trap for Mebius. When Mebius finally arrived, Hikari announced he had joined the four kings and the group ordered Mebius to retrieve the Giga Battlenizer or the captured Ace and Taro would be killed. When Mebius returned with the ancient artifact, Hikari quickly snatched it from Mefilas and reveal his trickery just to rescue his fellow brothers in arms. During the fight between Ultra Brothers and the Heavenly Kings, he was betrayed by Armored Mefilas, deeming the former weak. Ultraman Mebius Gaiden: Ghost Rebirth

Mega Monster Battle: ULTRA MONSTERS NEO

Armored Grozam's card in the game.

In the 2007-2010 arcade game, Grozam appeared as one of the enemies, tag-teaming with a Kyrieloid.

In episode 3, both of them encountered the player/protagonist and Kanegon (both of which are Reionics) and challenged them. Grozam as well summoned the help of an Inpelaizer until he was killed by the timely arrival of Ultraman Tiga

In episode 11, he was revived and bestowed by the powers of his former master's Armored Darkness into Armored Grozam (アーマードグローザム Āmādo Gurōzamu). He fought against the protagonist and died once more in an explosion.


Ultraman Mebius

Mega Monster Battle: ULTRA MONSTERS NEO



  • The episode of Ultraman Mebius with Grozam is inspired by the two parter in Ultraseven where Seven was crucified and had to be rescued by his human allies. Mebius was even locked in ice in a similar position as Seven was when he was placed in his crystal cross.
  • Unlike other members of Heavenly Kings, he prefers on brute strength and face-to-face with his enemies, due to his own confidence in his regeneration ability.
    • However as confirmed by Alien Mefilas, the reason of Grozam's defeat is due to his reliance on his brute strength and for underestimating the earthlings.
  • Unlike the Reionics Mefilas who acquired his Armored form by using the salvaged Darkness Broad, Grozam was bestowed by the sentient armor himself. In other words, he obtained blessings from the armor whereas Mefilas seemingly took the power against the armor's own will.
