―Deathrem ~ Deathrem's Plot

Deathrem (デスレム Desuremu) is an Alien Deathre member of the Dark Four Heavenly Kings and is one of the antagonist of the penultimate arc of Ultraman Mebius. He served Alien Empera as the ruler's Strategist General (謀将 Bōshō).

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-Monsters under his servitude. As he departed, Deathrem expressed his anger for having Yapool go first despite not being his turn until Mefilas calm him down to witness his progress.

Following Yapool's defeat, Deathrem captured the Phoenix Nest and had most of the GUYS members on board as captives while letting George Ikaruga escape just to relay a message to Mebius: surrender himself to be destroyed in exchange of Crew GUYS' lives. Appearing in the sky and dropping to the city, the invader began to wreck havoc. Mebius quickly appeared, but he couldn’t attack the fiend. As the hero was thrashed by Deathrem, he revealed to the world the true fate of the Phoenix Nest, and this began to turn the people on Mebius: he’d rather protect GUYS than the civilians.

Caught in a conundrum, Mebius began to doubt himself. Leaving the rookie warrior on his own, Deathrem returned to the last three Heavenly Kings to gloat. He soon returned once again to finish off Ultraman Mebius, but the team trapped in the containment field found a way to communicate with the world. As Mebius challenged Deathrem again, they begged the warrior to protect the people and forget about them. Hearing their pleas, Ultraman Mebius attacked the vile alien. With the trust between mankind and the Ultras restored, Deathrem was furious and tried to destroy the Phoenix Nest with a storm of energy until Ultraman Jack appeared and defend it. This allowed Mebius to fully concentrate on Deathrem as his plan fell apart. Struggling and in shock, Deathrem was completely obliterated from a single shot of the Mebium Burst and Jack's Spacium Beam.

The Dark Four Heavenly Kings

Several years passed since the death of the Dark Four Heavenly Kings and the destruction of the Emperor. Deathrem remained in the legendary Monster Graveyard until he was revived with fellow members of the 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, Deathrem assaulted Ultraman Taro, but his powers were no match for the skilled hero. He was tossed to the side and with a single strike from the Strium Beam, Deathrem was completely obliterated.
