Gatanothor (ガタノゾーア Gatanozōa?)[1] is a powerful kaiju, and the final antagonist who appeared in Ultraman Tiga. Its alternate names are Gatanothoa or Gatanozoa, with the latter being the most well-known and still in common use.

Anicent Times

The Ruler of Darkness, Gatanothor is responsible for the annihilation of the ancient humans that roamed the planet millions of years ago, having surfaced from the mythical city of R'lyeh. After covering the world with perpetual darkness, Gatanothor's reign of terror affected all life on the planet. But when the age of darkness neared its end, Gatanothor, along with its followers (called Zoiger) went into the ancient city of R'lyeh island and hibernated.

Ultraman Tiga

During modern times Gatanothor and its brood awoke once more. The Ruler of Darkness sought to have Earth revisit its dark past. But unlike the last time, a titan stood in Gatanothor's way: Ultraman Tiga. The Warrior of Light defied Gatanothor's rule and pledged to fight for humanity. After dismembering one of the Zoiger, Daigo summoned his courage, and the love he had for the entire human race. Ultraman Tiga arrived to face Gatanothor, but the Warrior of Light only had Daigo's light to power him, and he was easily defeated, despite the usage of the Delcalium Light Stream and a modified Zepellion Ray in his Power Type. Gatanothor then used a beam which turned Tiga back into a stone statue. Bellowing in triumph, Gatanothor struck the statue with one of his tendrils, knocking it down and leaving it to sink deep into the ocean.

Gatanothor now stood unopposed and allowed its darkness to sweep across the globe. There was nothing that could stop it or the Zoigar from ruling supreme. But the Ruler of Darkness didn't expect GUTS to band together to help stop the horrific beast. GUTS had enlisted Keigo Masaki, ex-host of Evil Tiga to help with Tiga's revival. His plan failed, but caused the people to unite. With humanity taking up arms and uniting, their hopes manifested into the forms of pure light, and poured into Ultraman Tiga's Color Timer. Ultraman Tiga was revived & later confronted Gatanothor in the ancient city. With great power never before seen, Tiga succeeded in easily sending the Ruler of Darkness to oblivion with a combination of Tiga's Glitter Bomber, two Glitter Vanishers, Glitter Zeppelion Ray, and finally the Color Timer Flash. The Earth and humanity was saved and the Spark Lens disintegrated into dust soon after.


  • Gatanothor is based on the Cthulhu Mythos deity, Ghatanothoa, whose name is spelled (in Japanese) the same way as Gatanothor. Like Ghatanothoa, Gatanothor has petrifaction ability. Its role, however, as well as fact that Gatanothor's resting place is the submarine ancient city R'lyeh, is derived from Ghatanothoa's father, Cthulhu.
  • Gatanothor is the first kaiju that managed to end Tiga's life, reverting the Ultra into a stone statue.
  • Gatanothor's name is never mentioned in the narration of the episode. It is referred to as the "Master of Darkness" to play on his omnipotent nature.
  • The porous texture that covers Gatanothor's shell are shared features with Golza, MelbaGalra and the Zoiger, as all of them are related as Super Ancient kaiju by nature. Unlike Gatanothor, their main reason is to act as a disguise for peepholes for the suit actors to use.
    • Gatanothor's curved shell also means that he resembles a combination of various Nautiloids and other sea creatures, including the extinct Ammonite.
  • Gatanothor's roar is a reused and slightly modified Desghidorah roar, which in turn was made of modified elephant trumpets.
  • Gatanothor is the first kaiju in the Ultra Series that has his head upside down.
  • Although not physically seen, Gatanothor is one of the monsters that makes up Beryudora's body in Mega Monster Battle: Ultra Galaxy Legend The Movie.
  • Gatanothor has instant kill and unblock special attacks in Ultraman Fighting Evoultion 3, similar to Ultraman Legend.
  • Both episodes were later featured in episodes 16-17 of Ultraman Retsuden.
  • Gatanothor shares some similarities with Mururoa from Ultraman Taro.
    • Both of them defeated an Ultra on their first try. However, Gatanothor managed to end an Ultra's life, Mururoa didn't.
    • Both hate light.
    • Both are accompanied by their servants to aid them in attacks.
    • Both of them are able to cover the Earth's sky with their darkness/black smoke.

Ultraman Tiga: The Final Odyssey

Although Gatanothor did not appeared physically in the movie, his hatred and anger of Ultraman Tiga is transfered to Camearra and the unification of the dark energy from Ri'lyeh allowed her to transform to her monstrous form, Demonothor after knowing Tiga/Daigo had fallen in love with another woman.

Ultraman Ginga

Gatanothor's Spark Doll was seen in Dark Lugiel's collection room inside Furohoshi Elementary School, meaning a version of him fought in the Dark Spark War. It is assumed that he returned to space in his original form after Ultraman Ginga defeated Dark Lugiel.


  • An actual Spark Doll of Gatanothor was sold as part of Premium Bandai in 2016, packaged alongside Spark Dolls of petrified Tiga Strong Type and Glitter Tiga.[2]

Ultraman X

Gatanothor appeared as a Cyber Card In the final episode of Ultraman X. After Ultraman X spoke out to Gomora and striked Greeza right in the center of his chest, Gatanothor, along with all of the other Cyber Cards, traveled to X and united with him. Cyber Gatanothor's power was used to help form the Hybrid armor and power up the Ultimate Xanadium to defeat Greeza once and for all. Gatanothor, along with the numerous other Cyber Cards and Spark Dolls, then appeared and thanked Daichi as he thanked them.Land of the Rainbow

Ultraman Orb Chronicle

Chapter 4: "Fierce Battle! Ishtal Civilization" arc

Gai arrived on Earth after recieving his mission to stop the revival of the King Demon Beasts, and the first was Magatanothor (マガタノゾーア Magatanozōa?), who was the King Demon Beast of Darkness, sealed away by Ultraman Tiga a long time ago near Ishtal Civlization. Jugglus Juggler, whom dressed up as the mummy under the alias Nuru Ra Hotep, as the leader of the religion Magacism (マガ教 Maga Kyō? Maga-Teachings) (a cult that praises Magatanothor) told Ishtal people about their impending doom. Magatanothor was freed through Dodongo's card which Juggler obtained after Ultraman Orb had defeated it earlier, wreaking havoc and destruction to the buildings of Ishtal. Gai transformed into Orb and fought it in an intense battle that released so much heat the nearby sand turned to glass. Orb defeated it after a tough fight but the battle causes Ishtal to turn into a place known as Kemati Buki (Hill of Death) (ケマティ・ブキ (死の丘) Kemati Buki (shi no oka)?), as well as the theory of an ancient superscience war by archaeologists 4000 years later. Juggler took off his disguise and collected Magatanothor's Kaiju card while Gai receives Ultraman Tiga's card.

Chapter 6 "The Wandering Sun" arc

Although he's not physically seen in this series, Magatanothor's card is shown to be in possession by Jugglus Juggler, whom he obtained 4000 thousand years prior to the series. The card of Magatanothor was used alongside other King Demon Beasts to unveil Maga-Orochi's egg. In the finale, Magatanothor's power is used alongside other King Demon Beasts by Magata no Orochi in its rampaging spree.


  • Magata no Orochi's tentacles (which was from its blood vein-like features) is confirmed to be from Magatanothor by Kiyotaka Taguchi in his Twitter account.[3]
  • Many believe that Magatanothor's name is a spelling error, thus preferring to call it as Maga-Gatanothor (マガガタノゾーア Maga Gatanozōa?). The change of original name is due to the repetition of the Katakana letter "Ga" (ガ?), thus making the Gatanothor part being redundant.
  • In the original toy catalog release, Magata no Orochi was mistaken by many fans to be a combination of Maga-Orochi and Magatanothor, due to their names.
    • Magata no Orochi's name was previously written as Maga Tano-Orochi by fans before the airing of episode 24.
  • Alongside Maga-Pandon, Magatanothor is largely identical to its original variant, with the Maga Crystal being the only differences as well as the addition of purple colourings on its shell.
  • In the commercial for Juggler's Dark Ring, Magatanothor's Kaiju Card bears Tiga's crest, however the official website for Ultraman Fusion Fight depicted the card with Orb Origin's crest.[4]
  • Despite appearing as a card in the original series, an actual design of its suit does exist in addition to the study of Magatanothor's coloration.
  • Alongside Maga-Zetton, Magatanothor was never mentioned in the Pacific Records. This may be due to the fact that they never set foot in Japan.
  • In a similar fashion to its predecessor, Magatanothor had also destroyed a civilization, Ishtal.
  • Unlike predecessor, Magatanothor does not come from or fights an Ultra on the sea, instead it comes from and fights an Ultra at a desert as evidence from the melting of sand to glass.


  • Height: 150 m[5]
  • Length: 200 m[6]
  • Weight: 200,000 t
  • Origin: R'lyeh in the South Pacific → The super ancient civilization on R'lyeh Island (First sighted in modern times) (Neo Frontier Space Timeline)
Powers and Weapons
  • Petrifaction Ray (石化光線 Sekka Kōsen?): Gatanothor can fire a purple beam of energy from the portion of shell above its head. This beam actually pierces through the opponent's body and turns them into stone in just few seconds. It is alternatively called as Penetration Lazer (貫通レーザー Kantsū Rēzā?) in Fighting Evolution 3.
  • Tentacles: Gatanothor has many tentacles located around his head. It can have these tentacles stretch out to great lengths to ensnare distant foes. It can also use these tentacles to lash out as weapons.
  • Pincers: Gatanothor has four giant pincers on the end of its longest tentacles. These pincers can be used effectively in melee combat.
  • Shadow Mist (シャドウミスト Shadō Misuto?): Using its unnatural powers, Gatanothor can cause never-ending darkness to plague the earth. When spreading, the darkness takes the form of black clouds that can kill small beings, like humans, on contact. And for the larger beings, it causes explosion when come into contact.
    • In Fighting Evolution 3, Gatanothor was able to shroud the entire screen. Players need to use Cheat Machine to change the value to 37 in Custom Mode and you can see the there is two selection, Black Gas and Power Up in the R1/L1 section.
  • Shell: Gatanothor is protected by a gigantic shell that can withstand all but the most powerful attacks. It proved effective against the Delacium Light Stream and Zepellion Ray, but was helpless against Glitter Tiga's attacks.
  • Length Increase: Gatanothor can increase his length by showing his bottom part of his body, even it can only tower an Ultra. It will also show his Pincers as hands and lots of his tentacles. Doing so, Gatanothor's eyes will turn to red and he becomes more brutal.
  • Combined Assault: Gatanothor can use both his pincers and his tentacles at the same time, used to ensare Tiga's both hands before turning him into a statue with his Petrification Ray.
  • Giant Claw Knockout (巨爪叩きつぶし Kyosō Tataki Tsubushi?): An attack which involves hitting the opponent with its pincers.
  • Evil Genocider (イーヴィルジェノサイダー Īviru Jinosaidā?): A tag-team attack with Evil Tiga. Evil Tiga jumps onto Gatanothor's back while the monster exhales Shadow Mist to confuse the opponent. The former soon attacks the disoriented opponent until Gatanothor launches Petrifaction Ray to freeze them. Evil Tiga absorb Gatanothor's Shadow Mist to empower his own Evil Shot towards the petrified opponent.

Gatanothor's weakness is light, being the main reason why he covered the Earth's sky with Zoigers and clouds of darkness.
