Ultraman Wiki

Deathfacer (デスフェイサー, Desufeisā) was a robot servant of the Alien Monera. Originally a TPC battleship Prometheus, it was manipulated by the said aliens to become their ultimate weapon.

Ultraman Tiga & Ultraman Dyna: Warriors of the Star of Light[]

A huge robotic weapon created by TPC as the Prometheus battleship, the robot revealed itself back on base after being "mollusionized" by the Monera Aliens. When challenged by Ultraman Dyna, the robot dominated the hero, blocking his attacks and decimating the area with its Gatling gun. After the hero turned into his Miracle Type and its attacks were reflected due to the machine's shield, Deathfacer drifted into the sky and prepared to fire the Neo Maxima Cannon! Dyna managed to escape the blast, but the whole island was reduced to a smoldering crater.

Not long after, Deathfacer was unleashed on Japan. Super GUTS attacked it with little effect. One of the crafts was lodged in a skyscraper. The machine prepared to fire an energy beam, but just before it could get a direct hit, Asuka called on Ultraman Dyna for the rematch.

The hero arrived in his Strong Type and lifted the alien war machine up. The robot still managed to fight back, matching Dyna's strength to its fullest. After its other attacks failed, Deathfacer tried to use the Neo Maxima Cannon. Before he could fire again, Dyna thrust his hand right through its body! Stunned and half-destroyed, the powerful robot was helpless as he was hoisted into the air and thrown into the sky where its body exploded from the damage it sustained.

  • The Deathfacer was originally named the Genocyber (ジェノサイバー, Jenosaibā) in the early design stages.[1][2]
    • No thought was put into how the Prometheus was transformed into the Deathfacer. Heavy panel linings were added onto the design to present how extensive the ship was transformed.[2]
    • There was originally an orb object in between the head horns. The designer Hiroshi Maruyama intended it to be constantly moving with the use of CG and later changed to the use of a motor, but it was ultimately scrapped.[2]
  • The sound effects made by Deathfacer are a combination of those made by Zamu Revenger and Alien Reguran.
  • Deathfacer's costume would be reused years later to make the robot, Beatstar.
  • The Prometheus is a prop modified from Mydo's battleship, Sky Shark.
  • A schematic of the Prometheus is visible on the front page of a Team EYES TECCH Thunder's operations manual.[3] Warm Memories
  • In Dark Lugiel's collection in Ultraman Ginga, Deathfacer was visible as a Spark Doll along with Ace Killer, Mecha Baltan, Alien Hipporit, Alien Babarue, Ghighi, Mochiron, Gatanothor, Goldras, Birdon, Gan-Q, Twin Tail, Dada, and a lot of other monsters and aliens.

Ultraman Dyna[]

Deathfacer was one of the hallucinations experienced by the Super GUTS members before morphing into Evil Tiga and later Moravia. The Power of Thinking of You

Mega Monster Battle: Ultra Adventure[]

Raybrad possessed Deathfacer

The Reiblood-possessed Deathfacer.

In the manga, the Prometheus battleship is said to be created by mankind to be an invasion warship. Alien Reiblood recreated the Reionics Battle to gather all Reionics in one place, at the same time using Prometheus to collect the combat data of Io and his Gomora. Reiblood then took the battle to Io's planet Earth, wherein he destroyed the monsters to absorb their energies and further empowering his own being. Io summoned his Gomora and Vittorio's EX Gomora to fight against the possessed robot. Despite the possession of Gomora's combat data, Deathfacer fails to calculate EX Gomora and in the end defeated by both monsters when combining their finishers: W Ultra Oscillation Wave (Zero Shoot).

The manga itself is also adapted into the game premise of Mega Monster Battle: ULTRA MONSTERS (predecessor of RR) where the player took control of Io himself and their monsters being optional to their choice. As Deathfacer, since Bemular's part was omitted due to the nature of the game, Vittorio blocked the Neo-Maxima Cannon and survived but heavily exhausted, he gave the player his Battlenizer to perform Double Monsload, therefore defeating Deathfacer.




Main article: Prometheus
  • Length: 154 m[4][5]
  • Width: 72 m[4][5]
  • Weight: 1920 t[4][5]
  • Origin: Coreomeos Island, Earth
  • Flight Speed: Mach 3.3 (in-atmosphere)[4][5]
Powers and Weapons
  • Neo Maxima Cannon (ネオマキシマ砲, Neo Makishima-hō)[6]: A high energy weapon powered by the Neo Maxima Engine. It is far more powerful than the Maxima Cannon such as the one used by the Artdessei. At maximum output, the cannon is capable of destroying entire asteroids. The Prometheus has one concealed in the lower hull at the front. When in use, the barrel would extend out as it begins the energy charging sequence.
  • Twin-Barrel Gun Turret: Eleven are scattered around the ship's hull.
  • Autocannon: The ship's multi-barrel rapid-firing armament.
    • Casemate Type: Five are mounted on both sides of the wing hull parts, totaling ten.
    • Fixed Type: Two are mounted in front of the rear bridge tower. They can only fire forward.
  • Brainwave Scanning Capsule: Located inside the center of the Main Bridge, this human-sized machine reads a person's memories and converts them into data. The data would then be used to train the ship's main computer.
Ultra Adventure
  • Transformation: The Prometheus can independently transform into Deathfacer. This is presumably as a result of Reiblood possessing the ship, or as he stated, the ship was already modified by the invaders (hence implying that "Deathfacer" is a hidden feature to it).

Ultraman Tiga and Dyna Deathfacer render
  • Height: 77 m
  • Weight: 96,000 t
  • Origin: Earth
Powers and Weapons
  • Gatling Gun (ガトリングガン, Gatoringu Gan)/Gatling Gun Indiscriminate Firing (ガトリングガン乱射, Gatoringu Gan Ransha)[7][8][9]: A rapid-firing multiple-barrel weapon restructured from the Prometheus’ left wing and long-barreled autocannons. It serves as Deathfacer’s left arm.
  • Death Scissors (デスシザース, Desu Shizāsu): A pincer claw restructured from the Prometheus’ right wing. It serves as Deathfacer’s right arm. It can be launched out and quickly retract, dragging its opponents in close.
    • Death Scissor Ray (デスシザーレイ, Desu Shizā Rei): After targeting, Deathfacer can charge and fire a powerful ray from the top of the wrist.
  • Neo Maxima Cannon (ネオマキシマ砲, Neo Makishima Hō): Deathfacer has the highly destructive Neo Maxima Cannon loaded into its chest. The beam it fires is powerful enough to obliterate an island and could theoretically overpower Ultraman Dyna’s Solgent Beam and destroy the Ultra.
  • Geno Mirror (ジェノミラー, Jeno Mirā): Deathfacer can generate a black energy barrier when its arms are crossed. The barrier can block and reflect energy attacks back to their source.
  • Knowledge: After scanning Asuka’s brain, Deathfacer possesses all known information of Ultraman Dyna.
  • Flight: Deathfacer can travel in the air with the use of the thrusters on its legs.
  • Burrowing: Deathfacer can burrow underground and pierce through the surface.
Mega Monster Battle series
  • Life Force Absorption: While under possession of Alien Reiblood, Deathfacer can absorb the life force of defeated opponents to empower its own being and Reiblood's spirit even further.

Spark Doll[]


Deathfacer became a Spark Doll in the conclusion of the Dark Spark War due to the Dark Spark's powers. His Spark Doll was kept in Dark Lugiel's collection.
