Ultraman Wiki

Zaigorg (罪業苦ザイゴーグ Zaigōgu lit. "Sin Suffering") is a Kaiju that first appeared in Ultraman X The Movie: Here He Comes! Our Ultraman as the main antagonist.

Subtitle: Inferno Demon Monster (閻魔獣 Enma-jū)



Zaigorg's name comes from the Japanese word Jigoku (地獄"hell"), also romanized as Zigoku.


Zaigorg is designed by Masayuki Gotoh to emphasize a monster as a movie villain in contrast to the humanoid Etelgar. In addition to the Toho monster Varan for its body spikes and Arch Belial's eyes, Zaigorg's design incorporates the elements of appearing Kaiju in Ultraman to commemorate the Ultraman Series's 50th anniversary and elements of hell in Japanese culture to complement Zaigorg's origin.

  • Eyes: Alien Baltan
  • Face: Neronga
  • Chest: Greenmons
  • Tentacles and tail: Suflan (Additionally in real life, the props used to portray Zaigorg's tentacles were modified Suflan props made for attraction purposes.)
  • Arms: Red King

  • Horn: Oni's horn. The Oni is a vile creature in the Japanese mythology and is also syncretized with Hindu-Buddhist creatures such as yaksha and rakshasa as wardens of hell.
  • Right hand mace (Gorg Regjis): Oni's Kanabō
  • Tail: Jigsaw, referring to the Hell of Sawing from the 18 levels of hell.
  • Mouth: Chinoike Jigoku (血の池地獄“Blood pond Hell”), one of the Hells of Beppu.
  • Eyes: Refers to Avici (known in Japanese as abijigoku (阿鼻地獄) or mukenjigoku (無間地獄)), one of the Eight Great Hells where prisoners spent in eternity tormented by a fire-breathing 64-eyed demon.
  • Back: Mountains of needles, referring to the Hell of the Mountain of Knives from the 18 levels of hell.


Ultraman X The Movie: Here He Comes! Our Ultraman

Long ago, Zaigorg was sealed away by a team of ancient giants (including an alternate Tiga) in the ancient Baradhi ruins in Area A2 and he stayed that way until a greedy treasure hunter named Carlos Kurosaki took the ball that sealed the monster, believing it to be a priceless treasure, and unintentionally freed the monster from its prison. After rampaging throughout the countryside near the ruins, he was immediately met with opposition by Ultraman X, but he held the upper hand against him due to his mace hand and tough hide. X then transformed into his Exceed X form to try to relinquish all of the negative energy from the monster with his Exceed X Slash, but Zaigorg batted him away with his tail at the last minute and fired his Bloody Flooding at him, causing Daichi to separate from X, the Ultra to break down, and his X Devizer infected, preventing him from transforming. With that chore done, Zaigorg burrowed underground to fight another day.

Zaigorg travelled underground and reappeared in Area S-2 to destroy Carlos Communications and the stone that imprisoned him in the first place to avoid being imprisoned ever again. Once again, the monster was met with opposition after being forced to emerge from underground thanks to Cyber Gomora and he had to deal with him and the Xio Musketty systems. After enduring attacks from the powered vehicles (With Red King and King Joe powered attacks), the cybernetic monsters' attacks, and the electrical field meant to contain him, Zaigorg used his spines to defeat Cyber Gomora and summon his minions, Gorg Antlar and Gorg Fire Golza, at the same time. With those obstacles taken care of, all three of them proceeded to rampage throughout Tokyo but Xio refused to give up and continued to attack him from both the air and the ground, but even when having his mouth stuffed with cotton candy, Zaigorg just kept on rampaging throughout the night with his minions.

But suddenly, the three of them came face to face with not only the recently revived Ultraman X but also Ultraman and Tiga, the Ultras who sealed him in the first place. The two forces then collided with each other in an all out brawl with the Ultras received assistance from Xio. While Antlar and Golza were destroyed by Tiga and Ultraman respectively, X countered Zaigorg's techniques with his own and seemingly destroyed the monstrosity with the Xanadium Beam. He then got back up, revealed his chest mouth and tendrils, and used them to suck the energy out of all three Ultras to become stronger, all the while sending five Tsurugi Demaagas to major cities all across the planet.

Just when all hope seemed lost for Daichi and the others, the Cyber Cards of Ultraman and Tiga appeared in front of Daichi and he loaded them with his X Deviser, turning them into the the X Beta Capsule and X Sparklence respectively, and combining them to form the Beta Spark and debuted his new Beta Spark Armor. X used his new powers to gain the upper hand over Zaigorg by cutting off his tendrils and his mace hand and even using his Cyber Wings to give Ultramen Zero, Max, Nexus, Victory, and Ginga (who were somehow transformed from their Cyber Card forms) the strength they needed to kill all the Demaagas they fought. Zaigorg then prepared to fire a more powerful Hell's Relieve from his chest mouth as a last resort, but X survived the attack without a scratch and fired his Beta Spark Arrow at the ancient monstrosity's chest, ending his reign of terror for good.


  • Zaigorg is the second Kaiju whose Cyber Power is the maximum 25/25 rating, the first being Greeza. Like the former monster, Zaigorg also shares the same motif to Ultraman X, as its chest mouth opens to reveal an "X"-shaped formation.
  • Director Kiyotaka Taguchi stated the Xlugger is ineffective against Zaigorg as Daichi's emotions are beyond comprehension, relating to his stated origins (that being hell).

Ultraman Geed


Zaigorg was summoned by Kei Fukuide via his Riser in a Kaiju Capsule to take on a Dada in his own personalized Legionoid. While he was overwhelmed by the robot at first with his close quarters combat, Zaigorg quickly fought back and overwhelmed it with his own moveset. Eventually, Zaigorg bit on the robot's drill, knocked him away with a punch from his club, and destroyed it with his Bloody Flooding, subsequently killing the Dada in the process.

Things got worse when Kei joined Zaigorg by his side by becoming Thunder Killer. Riku Asakura then transformed into Ultraman Geed in his Primitive form to fight them. Throughout the fight, Geed managed to hold his own against the two Kaiju with his experience, skill, and athleticism at first, even though they outnumbered him, but the two of them ganged up on Geed and held on him on the ropes with their teamwork. In order to stack up to their levels, Geed transformed into his Royal-Mega Master form.

While he was in this form, Geed was able to hold both Kaiju at bay with his sword while swiftly and majestically dodging their attacks. The Ultra then defeated Zaigorg by utilizing Ultraman Jack's Ultra Capsule with his King Sword, and firing his Lance Spark at the latter, destroying him in the process. Inheritor of the Dream


  • Zaigorg is the first monster out of Kei's Kaiju Capsule summons not to be a robot.
  • As of Geed, the Ultras who defeated Zaigorg are users of two Ultramen powers combined into a single form, and defeated by an energy beam that penetrated its chest.
  • Zaigorg's suit would be modified into Snake Darkness.[1]
