Ultraman Tiga

Voiced by: Yuji Machi (series; stock grunts), Hiroshi Nagano (The Final Odyssey and Superior Ultraman 8 Brothers), You Murakami (Ultraman Ginga S)
The last of a race of prehistoric giants that lived on Earth thirty million years ago, Tiga and his brethren were the protectors of an ancient civilization until its destruction at the hands of Gatanothor, who sealed Tiga and his kind in stone until he was rediscovered by Daigo Madoka. As the first Ultra hero with a full series since Ultraman 80, Ultraman Tiga's debut marked a new era for the Ultra Series, set in a new universe. He quickly became one of the most popular Ultra heroes as a result, and has since made return appearances in other series, like Ultraman Ginga and Ultraman X eventually getting a bigger role than before in the pseudo-remake series Ultraman Trigger: New Generation Tiga.
  • An Ice Person: Tiga gains ice-related powers whenever he switches into Sky Type. His arsenal includss creating a cold explosion that freezes kaijus instantly, or releasing an icy mist from above his opponent and encases the kaiju in ice.
  • Breakout Character: Franchise wise, Tiga has become one to the Ultra Series being perhaps the most popular Ultraman of the franchise overall and leaving him to inspire many other Ultras in terms of design and power. His series even gets a "remake" of sorts in Ultraman Trigger: New Generation Tiga where he is often mentioned in passing and alluded to.
  • Critical Annoyance: Like most Ultramen, the Color Timer on Tiga's chest flashes red and beeps as he runs low on energy.
  • Did You Just Punch Out Cthulhu?: All the Ultramen do this, but Tiga should get a special mention because the Big Bad of his series is none other than Cthulhu's son!
  • Empty Shell: The statue inside the pyramid is this, as the real Tiga departed it long ago, leaving it open for Daigo to possess.
  • Finishing Move: Each of his forms has a separate one — Multi Type uses the Zepellion Ray, Power Type has the Delacium Light Stream, Sky Type possesses the Rainbalt Light Bullet.
  • Heel–Face Turn: In The Final Odyssey, it was revealed that Tiga used to be evil and lead the Dark Giants as their most powerful member during a civil war between Ultramen that almost destroyed the 30-million-year-old civilization they protected. However, in his human form, he fell in love with Yuzare, who managed to turn him to the side of light and allowed him to seal his comrades away in stone.
  • High-Altitude Battle: Sky Type is meant to be this for any opponents with actual flying capability.
  • Legacy Character: Uniquely, Tiga is this. Over the course of his own series, there have been at least four separate Tigas all in the same bloodline: the original Ultraman Tiga who was the actual Giant of Light and existed 30 million years ago, Amui (who is implied to be Daigo's ancestor), Daigo, and Daigo's son Tsubasa. All of them merely inherit Tiga's light and power, with the original having left Earth long ago
  • Light Is Good: As a being of light. In fact, turning to the light marked his shift from being a power-hungry tyrant and leader of the Dark Giants to a heroic protector and leader of a group of heroic Ultras.
    • Dark Is Not Evil: In Ultraman: The Final Odyssey, he becomes Dark Tiga this when Camila convinces him Daigo become Tiga again. However, Daigo embraces both the goodness in his heart to control the evil within himself, preventing Tiga from succumbing to his old ways.
  • Love Redeems: His feelings for Yuzare is what made him change sides from darkness to light.
  • Meaningful Name: "Tiga" means "three" in Malay/Indonesian, referencing his three different forms.
  • Multiform Balance: The first Ultra Series hero with such an ability.
    • Jack of All Stats: Multi Type (Omni Mode in the 4Kids dub), his default form.
    • Mighty Glacier: Power Type (called Power Mode by 4Kids). He turns red and silver.
    • Fragile Speedster: Sky Type (renamed Speed Mode by 4Kids), in which he becomes indigo and silver.
    • Golden Super Mode: Glitter Tiga.
    • Superpowered Evil Side: Tiga Dark, as in his original form as a villain. According to his former teammates, this form's full potential can be realized if Tiga returns to the dark side he was once in.
  • Our Giants Are Bigger: While "Giant of Light" is a term frequently given to the Ultras, Tiga is unique in that he is an ancient denizen of Earth rather than an alien being, thus fitting more closely to the classic fantasy giant more than his space counterparts.
  • Purple Is Powerful: One of the few Ultramen with purple as a major part of his colour scheme.
  • Red and Black and Evil All Over: Averted. He's red and black yes, but Tiga Tornado is the result of stealing his former friend Darramb's strength while slowly returning to the light.
  • Sealed Good in a Can: Daigo discovered him as one. Though it's less the original Tiga himself, and more of his residual power left behind as a statue for the next host.
  • Shrink Ray: Tiga's Cell Change Beam, used in one episode to shrink King Molerat reducing the monster into a cuddly rabbit form.


The one and only!

Late in the series, as Daigo unintentionally enters a time machine that sends him to 1965, he ends up meeting Alien Charija, who intends to release a hibernating monster named Yanakagi, sealed in a lake by the original Ultraman. Predictably, Yanakagi ends up being released and immediately goes on a rampage, and at the peak of battle, Ultraman quickly makes a comeback to give Tiga some timely assistance. This Ultraman hails from the Land of Light like the original, but his connection to Tiga and the other Ancient Giants of Light is unknown.

First Appearance: The Ultra Star

  • Alternate Self: Unlike the original Ultraman, this one hails from the Neo Frontier Space World.
  • Big Damn Heroes: Ultraman's return quickly turns the tide of battle around, firstly by knocking Yanakagi off its feet, and then restoring Tiga's energy before assisting Tiga in dealing a fatal blow on the monster.
  • The Bus Came Back: While Ultraman had appeared in stage shows, music videos and Ultraman Story from 12 years ago, this was his first reappearance in a mainstream entry of the franchise in the Heisei era.
  • Clap Your Hands If You Believe: The original Ultraman is summoned back to existence by Eiji Tsuburaya's willpower and belief that the original protector of humanity would make a return.
  • Dynamic Entry: How Ultraman made his appearance - in a glowing red orb that whacks Yanakagi across the face, preventing the monster from draining Tiga's health.
  • Mythology Gag: It's especially fitting that the episode featuring the original Ultraman's first return in over a decade would have him fighting Yanakagi, a monster based on Bemular. Not to mention Yanakagi's Boss Subtitle being "Space Dinosaur", which is shared with Ultraman's original final opponent, Zetton.
    • The episode's credits pays tribute to Ultraman as well, using clips from the original 1966 show instead of from the episode itself.
  • Passing the Torch: Ultraman extending a handshake to Ultraman Tiga, after they've defeated Yanakagi together, pretty much established Ultraman had entrusted the all-important task of defending humanity to Tiga.

Fallen Ultramen

Evil Tiga

First Appearance: The One who Inherits the Shadows
Voiced by: Takashi Kora (grunts)
An unnamed Ultraman discovered by Keigo Masaki, who intends on merging with it to become a god. However, the Giant of Light is corrupted by the wickedness in Keigo's heart, becoming Evil Tiga.
  • Bad People Abuse Animals: His cold-blooded beatdown on Gardi is, if that wasn't obvious on what his alignment is.
  • Breakout Villain: Evil Tiga seems to be one of the most popular of the Fallen Ultramen, and has made many appearances in other forms of media relating to the Ultra series. He eventually became one of the main protagonists of the Darkness Heels stage shows alongside other popular evil Ultras such as Camearra and is also set to appear in the manga adaptation, Darkness Heels -Lili-.
  • Dark Is Evil: Is slowly growing into this trope when the colors of his beam attacks are dark purple.
  • Evil Counterpart: Pun of his name aside, his attacks are almost mirror match to the original Tiga, making it as if the hero fighting against his evil twin.
  • Fallen Hero: Evil Tiga is only evil because of its human host's selfishness and arrogance taking over the resurrected Ultra's body in the forced merging.
  • Finishing Move: Evil Shot; a reverse counterpart of Tiga's Zepellion Ray (his charging process was in reverse).
  • Light Is Not Good: At first glance, his body shines in glittering white hue and sheds off to reveal his white skin. Unfortunately, being driven insane from a forced combination makes him anything but good.
  • Kick the Dog: Literally! Evil Tiga viciously beats up Gardi, a dog equivalent of an Ultra.
  • Mysterious Past: Who he originally was and how he came to rest in his tomb with Gardi remains a mystery.
  • Only Known by Their Nickname: Evil Tiga is simply a nickname given by GUTS to describe the Ultraman driven to madness by Keigo's selfishness. No source has ever revealed the fallen hero's true name.
  • Sanity Slippage: Evil Tiga's corruption sees him become more and more brutal and feral in his combat style. Horii's words imply that not even Keigo was controlling his actions, meaning that said Ultraman was reduced to a rampaging monster.


First Appearance: Ultraman Tiga: The Final Odyssey
Voiced by: Masaru Matsuda (also human form actor)
One of a trio of evil Ultramen called the Dark Giants. He was once the best friend of Ultraman Tiga, but when was sealed away in stone long ago like the rest of the giants. Then two years after the defeat of Gatanothor, he is freed from his prison on R'lyeh by TPC.
  • The Brute: Of the Dark Giants, with the arrogance to fit one.
  • Cold Ham: He's rarely expressive, but his tone of speaking sounds dramatic in and on itself when he refers to Daigo/Tiga with "my friend".
  • Evil Former Friend: He was Ultraman Tiga's best friend before Tiga defected from the Dark Giants. Darramb still isn't happy that their friendship has long ended.
  • Gratuitous English: For some reason, he tends to spout a few random English phrases, with a fondness for calling Tiga "My Friend".
  • Mighty Glacier: Super strong, but doesn't have much else going for him beyond that. Tiga gained his Power Type by defeating him.
  • Playing with Fire: Can smash the ground with his hands to channel fiery eruptions as a Finishing Move.
  • Red and Black and Evil All Over: The only one of the Dark Giants to be coloured that way.
  • Sealed Evil in a Can: Imprisoned in stone for 30 million years and very much evil
  • Super Strength: His primary ability is that he's absurdly strong, even for an Ultraman.


First Appearance: Ultraman Tiga: The Final Odyssey
Voiced by: Tenmei Basara (also human form actor)
The second of the three Ultramen known as the Dark Giants, who share a mysterious and frightening past with Ultraman Tiga. He too was petrified long ago with his comrades and entombed in R'lyeh.

Voiced by: Miyoko Yoshimoto (also human form actor)
The leader of the Dark Giants. She was once Ultraman Tiga's lover until he imprisoned her in stone along with Darramb and Hudra. They remained there for thirty million years until the trio were awoken by a TPC expedition in the present.
  • Alas, Poor Villain: Her death scene is rather poignant, with her quietly lamenting how she wanted the light too.
  • Big Bad: Of Ultraman Tiga: The Final Odyssey as the leader of the Dark Giants.
  • Breakout Character: Like Evil Tiga, she's a rather popular character in the fandom, and her popularity led to many returns in stage shows and eventually to become one of the main protagonists of the Darkness Heels projects (including stage shows and the manga adaptation, Darkness Heels -Lili-).
  • Cold Ham: She is rather subdued and rarely raises her tone, until she sees Tiga saving Rena. But nevertheless, her presence is felt through her intense gravitas, even with playing mind games with Daigo.
  • Knight of Cerebus: Her very presence alone is enough to make the plot of the movie go darker than during Gatanothor's rampage.
  • Not Good with Rejection: Doesn't take it well when Tiga left her back then to redeem for his actual love for Yuzare. Even less so when she finds out about Rena.
  • One-Winged Angel: Whe she realizes that Ultraman Tiga/Daigo is now engaged with Rena, she calls upon Gatanothor's residual darkness to transform herself into a gargantuan shadowy version of Gatanothor called Demonthor.

    GUTS (Global Unlimited Task Squad) 
The defense division of the Terrestrial Peace Consortium (TPC), established by the United Nations at the end of the twentieth century as peacekeeping force. The lack of wars in the series' utopian vision of the twenty-first century means that GUTS primarily deals with the monsters and aliens that have replaced the social and environmental issues of the twentieth century.

The GUTS team

Daigo Madoka
Portrayed by: Hiroshi Nagano, Wayne Grayson (4Kids dub)

The bold and goodhearted protagonist. Daigo was formerly a member of TPC's transportation branch, but got a job at GUTS after he rescued General Sawai, the head of TPC, from alien abductors. He can transform into Ultraman Tiga using the Spark Lens due to the fact that he is actually a descendant of the Giants of Light.

  • Action Hero: Well, what you'd expect from the guy who's an officer that can turn into an ultraman.
  • Earn Your Happy Ending: After all the crap he goes through and battles he fights, he's notably one of the very few Ultras to actually get to retire after his line of duty as Earth's guardian is over. He retires with his wife Rena, and as shown in Dyna, goes on to live a happy life on Mars with two kids.
  • Half-Human Hybrid: The reason why he is able to become Ultraman Tiga is because he is both "a human and a being of light".
  • The Hero: Well, he is the guy who turns into Ultraman Tiga, isn't he?

  • Retired Badass: One of the very few Ultras to actually retire. He's still a combat trained officer and it's implied he can turn into Tiga again but is content in his retirement.

    Monsters and Aliens 

Golza / Fire Golza
Click here  to see Fire Golza

First Appearance: The One who Inherits the Light
A powerful monster from Earth's past that was reawakened in Mongolia during modern times alongside Melba to locate and destroy the petrified forms of Ultraman Tiga and his brethren. It later returned as Fire Golza after absorbing magma from a dormant volcano, increasing its strength to new levels.

Being the very first kaiju of the Heisei Ultra Series, Golza marked the beginning of a new era for the franchise. Thus Golza is one of the most popular monsters of the franchise and has frequently returned in later entries against other Ultra heroes. Starting with Ultra Galaxy Mega Monster Battle, he was officially added to the main Showa continuity.

  • Ambiguously Related: Its Boss Subtitles contains the words "Super Ancient" and it has a porous structure in its neck, not unlike the Zoiger's own structures, and it makes a beeline for Tiga and his allies upon reawakening, all of which might indicate that it is a minion of Gatanothor.
  • Art Evolution: As Fire Golza, the white spots on his body are now red and there are several vein-like growths covering his skin.
  • Breakout Villain: As the most popular Ultraman Tiga kaiju, Golza is one of the few to have regular reappearances and the opportunity to battle other Ultramen.
  • Expy: Was designed as sort of a modern re-interpretation of Gomess.
  • The Juggernaut: Especially noticeable in Ultra Galaxy, but even in its original appearance, Fire Golza was pretty damn durable, completely ignoring most of Tiga's punches and beam attacks, it even proves durable enough to survive its first fight and return much stronger.
  • Last of His Kind: Implied. A flashback in The Final Odyssey shows multiple Golzas fighting numerous Ultramen, suggesting the one in the series may be a survivor.
  • Magma Man: Golza becomes Fire Golza by absorbing lava. No word about if Melba can do similar things.
  • Mighty Glacier: Slow but brutish, in comparison to the more agile but easily destroyed Melba. Moreso as Fire Golza naturally.
  • A Molten Date with Death: How Fire Golza is disposed off, which also prevents a volcanic eruption threatening to wipe out a village.
  • Playing with Fire: As Fire Golza, its head laser is replaced with fireballs.
  • Prehistoric Monster: Along with Melba, both monsters come from millions of years ago and reawakened in the present to wreck havok.
  • Purple Is Powerful: Is able to shoot an ultrasonic ray of purple energy from his forehead.
  • Signature Roar: A loud guttural growl followed by a high-pitched screech.
  • Starter Villain: Marking the beginning of a new era for the Ultra Series alongside Melba as Tiga's first foe.
  • Starter Villain Stays: Goes into hiding underground after his defeat. Later on Golza returns having hibernated in the core of an active volcano for months, turning it into the nearly-unstoppable juggernaut of a monster called Fire Golza.
  • Took a Level in Badass: As Fire Golza, he absorbed so much heat it gave him a new set of fiery powers, and was only killed once and for all when Tiga hurled him into an erupting volcano. And even then, he somehow returned in Ultraman Dyna.
  • Tunnel King: Burrows about rapidly, travelling from Mongolia to Japan in a matter of hours.
  • Volcanic Veins: As Fire Golza, which he obtained from a volcano's power.

First Appearance: The One who Inherits the Light

An aerial monster similar to Golza in its origins. Melba was reawakened on Easter Island in the present to assist Golza in locating and destroying the petrified Ultras, leading GUTS in a race against time to awaken the ancient Giants of Light.

  • Ambiguously Related: Its Boss Subtitles contains the words "Super Ancient" and it has a porous structure in its chest, not unlike the Zoiger, and it makes a beeline for Tiga and his allies upon reawakening, all of which might indicate that it is a minion of Gatanothor.
  • Corrupted Character Copy: The Litra to Golza's Gomess. Unlike Litra, however, the two are allies and equally aggressive in their attempts to destroy the Ultras' statues.
  • Fragile Flyer: In comparison to Golza's Mighty Glacier, Melba flies circles around Tiga, landing a few lucky hits, until Tiga knocks it out of the sky — at which point it's disoriented and a sitting duck for Tiga's Ranbalt Light Bullet.
  • Giant Flyer: It's a kaiju, and all that.
  • Our Dragons Are Different: Its title is "Super Ancient Dragon" and it resembles a draconic creature with pterosaur features.
  • Prehistoric Monster: Both Melba and Golza are creatures from ancient times.
  • Sinister Scythe: It has huge sickle-like middle claws.


First Appearance: Legend of the Stone
A pair of subterranean monsters (implied to be mates) known in the stories of the local miners as naturally feeding on mineral matter. However, when the mines are emptied of resources, the beasts begin to terrorize the miners with their petrifying breath.

The second one used a mass sighting of an angel to instil panic of Judgement Day's arrival and form a cult against Ultraman Tiga that would allow it call forth an army of its kind.
  • Ancient Evil: So ancient that not even those from Tiga's period know their origins!

  • Spell My Name with an S: Also spelled "Gazote" or "Gazoto".
  • To Serve Man: Likes to eat humans, or as it calls them, "friends".

First Appearance: Halloween Night
Voiced by: Kyoko Fujinami
An evil witch from another dimension that comes to Earth every Halloween night to kidnap children and consume their hopes and dreams. On one night, she visited a small Japanese town that celebrated Halloween, but it happened to be that GUTS was visiting that very place to both enjoy the holiday and investigate a weakening between dimensions caused by the witch's arrival.
  • Child Eater: She abducts children, eats their dreams until they're Empty Shells, and then throws away the husk in her Graveyard of Dreams. She's done this in mass every Halloween that GUTS has on record. She finds adults unappetizing.
  • Dream Eater: Consumes the dreams of children, turning them into emotionless zombies she discards like used up trash.
  • Halloween Episode: Not only does Giranbo only appear on Halloween night, it takes the form of an old lady in a witch costume and transports kidnapped children to its home dimension in a vehicle resembling a giant jack-o-lantern!
  • Humanoid Abomination: A monster witch from a dimension called the Graveyard of Dreams, where it brings the children it's kidnapped to feed on their dreams and turn them into joyless husks.
  • Leitmotif: A rather twisted, musical-box version of "Ten Little Indians".

  • Attack Reflector: Makeena's bodily appendages are highly reflective, rendering beam attacks useless against it, especially when it enters its shell form.
  • Expy: Makeena is seemingly based on Kirara, both of them being non-violent guardian monsters who travels around the galaxy in sphere form, whose reason for landing on planet Earth is not to destroy earth's cities, but to escort an alien woman back to her home planet.
  • Non-Malicious Monster: The first Tiga kaiju that had no intention of destroying Earth. It was an escort for Saki to bring her back to her homeworld.


First Appearance: The Closed Amusement Park

  • Alas, Poor Villain: Horii and Ryosuke's girlfriend Sayaka feel bad for him when they realize Ryosuke's reasons for becoming Evolu.

  • Shock and Awe: Can shoot lightning bolts from his hands.
  • Superpowered Evil Side: Ryosuke lived in a constant state of torment between remaining human and metamorphosing into Evolu due to this.

  • Friendly, Playful Dolphin: Its motif.

  • Sea Monster: Based on dolphins in appearance and attitude.

But with their slave population on the brink of extinction, they turn to Earth to capture humans with shrinking guns and bring them to their homeworld as replacements.

Sakuna Oni

First Appearance: The Demon's Return
Voiced by: Moriya Endo
A fearsome oni that was originally defeated long ago by the samurai Kagetatsu, who then split the body into pieces and buried them.

  • Off with His Head!: Has the notable honour of being the last Ultra monster in the franchise to get decapitated.
  • Oni: A legendary demon sealed away centuries ago by a great warrior.
  • Pulling Themselves Together: Due to the fact that Kagetatsu split each of its body parts up when he buried them, Sakuna Oni's first act upon having its tomb's seal broken is to get itself back together, resulting in gigantic arms and legs popping up around the countryside.
  • Sealed Evil in a Can: The power of Kagetatsu's sword was what prevent his body from reattaching itself together until it was stolen.
  • Two-Faced: Sakuna Oni usually hides the second face underneath its hair.

  • Combining Mecha: Thousands of Gobunyu Vaha can merge to form Gobunyu Giga.
  • Humongous Mecha: As Gobunyu Giga.
  • Meaningful Name: Named after Goibniu, the Irish blacksmithing god and patron of smiths.
  • Mecha-Mooks: Of the mysterious space fortress that spawns them.
  • Mechanical Lifeforms: Yazumi discovers this when he gets his hands on a piece of a Gobunyu, as the robots are not powered by anything, making their insides hollow.

Gobunyu Ogma

First Appearance: GUTS into Space Part 2
A Gobunyu variant created directly from the mass of the flying mechanical fortress standard Gobunyu are created in to defend the fortress from invaders, such as GUTS when they land on the strange satellite in order to plant powerful explosives on it.
  • Diabolus ex Nihilo: Appears completely unexpectedly without foreshadowing when GUTS attempts to escape the fortress, if only to fill the monster fight quota.
  • Humongous Mecha: Formed directly from the substance of the space fortress itself.
  • Meaningful Name: Ogma was the Irish wisdom/eloquence god responsible for creating the Ogham alphabet as proof of his scholarly prowess and the wrestling champion of the Tuatha dé Dannan.

First Appearance: Deban's Turn
An evil alien that seeks to destroy the world by using its electromagnetic mind-destroying waves to drive humans into mindless berserk rages. However, since his abilities are nullified by those of his kindred Deban, his other priority is to kill the friendly little alien at all costs.
  • Archenemy: Of Deban.
  • Evil Laugh: His "roar".
  • Expy: The relationship between Enomena and Deban plays out a lot like Dogyuh and Bock, the former being a cruel, ruthless alien bully who delights in hunting down a harmless, younger member of their kin.
  • Hate Plague: Enomena emits electromagnetic waves that drive humans into violent insanity. To make matters worse, the waves also slowly destroy the human brain, eventually killing the victims unless Deban's calming waves save them.
  • Hate Sink: Out of the 40+ opponents encountered by Tiga, Enomena has the distinction of being perhaps the only one without any redeeming qualities. He spends the entirety of his debut episode hunting down the helpless Deban, who didn't really pose a threat to Enomena anymore and only desires to live peacefully with its adoptive family, and whenever Enomena is met with resistance from GUTS, the cowardly alien will use its teleportation powers to flee. His strategy consists of hunting down Deban and then fleeing like a Dirty Coward whenever met with resistance. When Deban seemingly pulled a Heroic Sacrifice to stop Enomena's Hate Plague, the vile alien then proceeds to attack the city, smugly believing there's nothing capable of stopping him now, until Tiga arrives to deal with him. And sure enough, when its clear that Tiga is easily stronger than him and winning the battle, once again Enomena attempts to teleport away while gloating to himself, until Tiga interrupts his teleportation and finally destroy him. Because for all the alien is worth, in the end of the day Enomena is merely a bully, a spineless coward and an absolute slimeball and complete jerk.
  • Jerkass: A bullying and violent being who revels in making people hurt each other.
  • More Hateable Minor Villain: While Gatanothor is the series' main antagonist, it doesn't appears until the final episodes, even if it sent monsters to do its bidding so it doesn't gets portrayed as too much of a bastard for the audience to hate. Enomena is a completely different story, being an alien invader written to be as despicable as possible, planning to drive humanity to destroy and kill each other by using a Hate Plague and hunts down an innocent alien, Deban, purely because he can.
  • Our Demons Are Different: Although he's actually an alien, Enomena's design is heavily based off demons. His Boss Subtitles is simply Majin (Demon).
  • Psychotic Smirk: Bears a permanent one on his face.
  • Shock and Awe: Can electrify his claws in combat.
  • Would Hurt a Child: While Deban's age, being an alien, is somewhat debatable, however the little alien's mannerisms and behaviour is no different from a child. And Enomena has NO qualms attempting to hunt and kill it anyway.


First Appearance: Deban's Turn
A friendly little alien that is apparently of the same species as Enomena but lives on Earth as a performer for a small circus troupe. He releases healing energy waves from his horns that nullify the destructive waves of Enomena, making him a target of the invader's attacks.
  • Aliens Among Us: Nobody notices though because the people he's living with wear their weird costumes wherever they go.
  • Disney Death: After seemingly sacrificing the last of his power to save Ultraman Tiga from Enomena's mind-destroying waves. He gets to keep performing with the circus guys as well!
  • Expy: To Bock, with Enomena being Dogyuh. See above.
  • Not a Mask: The circus troupe finds out about Deban's true identity after requesting for Deban to remove its mask.
  • What Measure Is a Non-Human?: The circus troupe he hung out with discovered Deban was a monster pretty early, but accepted him quickly and became good friends. When GUTS scientists ask if they can perform experiments on Deban's powers, the leader is outraged, and he initially refuses to let GUTS use Deban's powers against Enomena because it seems to him they're treating his friend as a weapon.


First Appearance: A Fog is Coming
Alien parasites produced from a strange living meteorite to feed it life energy from parasitized victims.

A male and female pair of Stenonychosaurus genetically modified by the Naga into humanoid servants to help them in their conquest of Earth. Having waited for their masters' return for millions of years, they are used by the ancient invaders to control the Weaponizers.
  • Red Oni, Blue Oni: The calmer and questioning Eve is the blue to the red Adam, who aggressively and loyally serves the Naga until he realizes he's been deceived.
  • Unwitting Pawn: The Dinosauroids believe that the Naga will let them inherit the Earth in the aliens' second conquest. The truth is the Naga really couldn't care less for Adam and Eve, seeing them only as tools to control the Weaponizers.

Alien Naga

First Appearance: Planet of the Dinosaurs
Voiced by: Mariko Takigawa
A race of evil aliens that conquered the Earth during the late Cretaceous period, but then left for unknown reasons. However, they planned on eventually coming back, creating the Dinosauroids and the Weaponziers as minions to assist them in retaking Earth in the present.
  • A God Am I: The whole race believe themselves as gods, which isn't too far of a stretch considering their power over creating life.
  • The Faceless: They never show up onscreen.
  • Hoist by His Own Petard: Tiga destroys their spaceship by hurling the Weaponizers' neutron bombs at their spaceship.
  • Invisible Aliens: The Naga never appear physically, only their voices are heard and spaceship is seen.
  • Sufficiently Advanced Alien: The Dinosauroids refer to them as being like gods and the Naga certainly view themselves as such.


First Appearance: Planet of the Dinosaurs
A pair of Tarbosaurus transformed into cyborg kaiju weapons by the Alien Naga. They were hidden away for millions of years, but baffled paleontologists soon discovered them, which the Naga and the Dinosauroids took as the opportunity to restart their conquest of Earth.
  • Action Bomb: The Naga outfitted them with neutron bombs for this. Worse still, they can merge their bombs together for an explosion capable of annihilating all life on Earth.
  • Chest Blaster: They have machine guns built into their chests.
  • Cyborg: Obviously.
  • T. Rexpy: Close. They're based on Tarbosaurus, a very close relative of T-Rex from Asia.

An upside-down monster that produces poison smog capable of killing large areas of forest. The creature had been slumbering underground for years, but twentieth-century vehicle exhaust seeping underground awoke it and allowed it to grow in power.
  • Acid Attack: Litomalus can spew explosive acid from its midsection that dissolves steel and kills vegetation.
  • Expy: Of Twin Tail from Return of Ultraman, in terms of design. It also have Gudon's whips.
  • Poisonous Person: Constantly secretes a toxic gas made from the vehicle exhaust it consumes that kills all plants in its surroundings.
  • Spell My Name with an S: Also called Litolumalus or Litmars.
  • Walking Wasteland: Once again, its presence kills all vegetation around it due to its poisons.
  • Whip It Good: Like Twin Tail, its primary weapons are the two whip tails on its top. Weirdly, it also uses them to pole vault during the fight.


First Appearance: The Rainbow Realm of Monsters
An immensely strong monster that dwells in a Bermuda Triangle-like dimension called the Rainbow Underworld, attacking any drivers unlucky enough to disappear into the realm through its rainbow gate, including an investigating GUTS and a trapped family.

Silvergon is one of the few kaiju from Ultraman Tiga that has appeared other entries of the Ultra Series, but usually as a more powerful version of itself called King Silvergon.

  • Achilles' Heel: Silvergon has extremely poor eyesight, only able to see moving objects. Tiga was able to take advantage of this once he found out by simply attacking Silvergon whenever it wasn't looking.
  • Breakout Villain: Though he doesn't recur as often as Golza, Silvergon is one of three Tiga kaiju to appear in other series.
  • Breath Weapon: Breathes blue fireballs in later incarnations.
  • Dimension Lord: Of the Rainbow Underworld, which is entered through the arches of a rainbow. Killing Silvergon ceases the realm's existence for easy escape though.
  • Dumb Muscle: Despite its ridiculous strength, Silvergon is easily fooled, and at one point in the fight, attempts to imitate Tiga by trying to perform a Zepellion Beam and transform into Power Mode.
  • Everything's Better with Rainbows: Not in this case. The rainbow is actually a gateway to Silvergon's realm. Interestingly, the rainbow gate has the colours in reverse, with violet on the top and red on the bottom.
  • Expy: Of Red King. The production team even liked to call it "Heisei Red King".
  • The Juggernaut: The Zepellion Beam barely even fazed this guy!
  • Living Motion Detector: As mentioned above, Silvergon can't see anything that stands skill, which Tiga takes advantage of (with some difficulty).
  • Super Strength: Even by kaiju standards. Silvergon is so strong that it can punch holes through a force field with its bare hands. Even Tiga in Power Mode had a tough time with him.


First Appearance: I Saw Obiko!
Voiced by: Shoichiro Akaboshi (also human form actor)
A youkai known in the folklore of Hikono Village as a mischief-maker who thrives in darkness, Obikoboushi (Obiko for short) disguises himself as a noodle vendor to scare people with his magical shadow. But when his pranks begin to grow more violent with the village's modernization, GUTS comes in to find out what's going on.
  • Alas, Poor Villain: GUTS feels pretty bad for him when they realize Obiko wasn't evil, just unable to let go of the past because he was afraid of being forgotten by his ancestral home.
  • Berserker Tears: He's heavily implied to be crying during his fight with Tiga, even wiping his eyes at one point. Upon close observation, one can also see sparks coming from below his eyes when he charges up his Breath Weapon, as if he's shedding tears of fire.
  • Breath Weapon: He and his magic shadow can spit fire.
  • Casting a Shadow: Obiko can only live in darkness, so he comes out at night to cause mischief. He also has a living mass of shadow accompanying him that assists in his scares.
  • Expy: A harmless monster who likes to hide in the shadows who spends much of the episode hiding from humans sure sounds a lot like Alien Pegassa.
  • Feed It a Bomb: GUTS defeats his shadow companion by shooting a signal flare into a portal hidden within a well connected to his shadow's pot, causing the pot to explode and revealing Obiko's location.
  • Living Shadow: His perpetual companion and partner-in-mischief.
  • The Magic Goes Away: An unfortunate victim of the modernization of the human world pushing out the magical creatures that humanity once feared.
  • Manchild: Played for Drama and combined with Immortal Immaturity. Obiko is a mischievous but harmless Youkai who enjoys playing pranks on the locals so that they wouldn't forget him, which makes it even more heartbreaking when he reacts with childish glee when the modernised village turns its lights off as part of GUTS' plan, thinking the village of old had came back. Even his fight with Ultraman Tiga plays out more like him throwing a tantrum over the loss of his home, with the Ultra trying to calm him down.
  • Mercy Kill: When GUTS tells him that the primitive village of the olden days is gone for good, he lets Ultraman Tiga kill him.
  • Non-Malicious Monster: Obiko is merely a mischievous monster who simply just misses the older days when the town he terrorized was just a quiet village without any streetlights.
  • Shock and Awe: In human form, he carries a magical staff that shoots lightning.
  • Teleport Spam: Can teleport between places of darkness, which he uses to frustrate GUTS when they're chasing him around town.
  • Voluntary Shapeshifting: His preferred form is a noodle vendor, with his magical shadow hiding inside the cooking pot.
  • Weakened by the Light: The reason why he enjoys the darkness so much and wishes that his home village would return to its pre-street lights days.
  • Youkai: Not based on any real examples, but is definitely meant to be one.

A strange monster that unexpectedly appeared from underground after it was awoken by radio waves being emitted by GUTS' communicators during a massive military operation conducted by them to destroy the Critters and end the Gazote menace once and for all.

Alien Natarn

First Appearance: A Memory of Blue Skies
An evil alien who comes to Earth in pursuit of two good alien siblings that have taken refuge in human hosts — Shinjoh (captured by the brother in search of his sister) and a popular singer named Maya Cruz (taken by the sister many years before, only to have forgotten her original identity).
  • Archenemy: Of the unnamed aliens that possess Shinjoh and Maya. His species were originally allies of theirs' but war broke out when Natarn's kind betrayed them.
  • Curb-Stomp Battle: Natarn's battle with Tiga lasts less than a minute and he doesn't even land a single hit on the hero! However, the episode focuses more on the unseen aliens in the bodies of Maya and Shinjoh, so really Alien Natarn was only there to fill the weekly fight quota.
  • Demonic Possession: Like the benevolent but never-seen aliens he's pursuing, Natarn possesses the human he encounters in order to sneak around on Earth.
  • Torso with a View: Tiga blasts a MASSIVE hole in its torso at the end of their brief battle.
  • Vader Breath: His "roar".

King Molerat

First Appearance: Monster Zoo
A simple mole mutated into a nocturnal kaiju by underground nuclear waste. The creature appeared near a zoo to doze one day, and although Rena believed the creature should be spared, the rest of the team were worried about what would happen if it woke up.
  • Glowing Eyes of Doom: Its eyes are visibly glowing when it begins its rampage at the end of the episode.
  • Hair-Raising Hare: His kaiju and domestic forms both resembles a rabbit.
  • Non-Malicious Monster: Unlike many kaiju, King Molerat is simply just an oversized animal — it doesn't want to destroy cities, only to do its own thing. It's for this reason that Rena opposes killing the creature and Tiga obliges to her pleas, turning the creature into a small and harmless form.
  • Shock and Awe: Shoots lightning bolts from its ears.
  • Weakened by the Light: Being a mutated mole, King Molerat can't abide sunlight and enters a drowsy state. However, moonlight sees it become an active predator.


First Appearance: GUTS Base Under Attack
Voiced by: Tomohisa Aso
An artificial lifeform from the planet of the same name, Bizaamo's purpose was to increase oxygen levels in the atmosphere. Its capsule was discovered in Antarctica by TPC scientists who hoped to use it for good, but the entity cared only about its need to evolve and multiply.
  • Belly Mouth: In kaiju form.
  • Blob Monster: Its normal form is a pinkish blobby creature. It turns into the form above by consuming enough electricity.
  • Energy Absorption: Consumes electricity in order to grow in strength and multiply.
  • Lack of Empathy: Despite its intelligence, Bizaamo ultimately reveals itself as bereft of compassion, for it cares only about its need to multiply and evolve, which is why it destroyed its creators' homeworld as it developed and attacked Horii when he tried to befriend it. However, GUTS feels pity for how such an intelligent being lacked compassion for others, preventing it from understanding how it could use its powers for good.
  • Our Monsters Are Weird: The name sorta gives it away, but just look at that thing!
  • Shock and Awe: The blob form has the ability to shoot lightning bolts, but the kaiju form can also create an electrical force field, shock opponents on contact, and spit lightning orbs from its Belly Mouth.
  • Technopath: Bizaamo can take over technology in its blob form, which it uses to feed off the device's electricity. If it takes over a device with communication (like Horii's laptop), it can speak through them.


First Appearance: Zelda Point Defense
The beloved pet cockatiel of Dr. Masahiko Nezu and his daughter Asami. Dr. Nezu had discovered a terrible chemical dubbed Zelda Gas, of which a single flask has the explosive power of a hydrogen bomb — and one misplaced flask killed Asami when it blew up their home. Dr. Nezu (on a business trip when it happened) would grieve for the rest of his life, while Shiela was mutated into a kaiju by the chemical explosion. Now, Shiela seeks to destroy the last of the Zelda Gas, which Dr. Nezu had hidden away at Zelda Point.
  • Ascended to a Higher Plane of Existence: After completing its purpose, it becomes a huge and beautiful phoenix-cockatiel hybrid made of light and soars off into space with Asami's ghost on its back, suggesting this trope is what happened.
  • Body Horror: Most of Shiela's skin and flesh is seared off, giving it a vaguely skeletal appearance. Near the end of the episode it also starts bleeding from the mouth, implying just living in this state is agony for it.
  • Breath Weapon: Breathes an orange beam of explosive energy. It also breathes a Tractor Beam, which it uses to safely take the Zelda gas away.
  • Expy: Of Hydra from the original Ultraman, another bird kaiju with a vengeful and tragic connection to a deceased child.
  • Eye Scream: GUTS blows out its left eye at the beginning of the episode.
  • Giant Flyer: Like all bird kaiju.
  • Non-Malicious Monster: Shiela's goal was to help Dr. Nezu get rid of the Zelda gas, so it could never be used to hurt people again.
  • Tragic Monster: And how! Shiela is just as haunted by the death of Asami as Dr. Nezu, so it seeks to destroy the Zelda gas to avenge the death of its owner.


First Appearance: Vampire City
A bat-like monster from South America that infects humans with a virus that turns them into vampires who serve it as its worshippers. It came to Japan in order to spread its virus and its cult further after it captured a journalist from Tokyo who had come to investigate rumors of its existence.
  • Bat Out of Hell: A gigantic bat-like monster that creates vampires and is worshipped by them as a god.
  • Blow You Away: Uses its wings to create huge gusts of wind. When Tiga attempts to intensify the light from his colour timer to destroy Kyuranos (like he did with Abolubas), Kyuranos uses it to blow shipping containers into his face and break Tiga's concentration.
  • Casting a Shadow: Kyuranos can create darkness in order to appear in daytime, which it does to battle Tiga.
  • Expy: A giant bat monster based directly on Draculas from Return of Ultraman.
  • Mind over Matter: Kyuranos uses telekinesis to send a dazed Ultraman Tiga tumbling about after draining a good deal of colour timer energy with its bite.
  • Our Vampires Are Different: Both Kyuranos and the vampires it creates are harmed by sunlight. The vampires also possess superhuman strength and agility while Kyuranos hide in a pocket dimension disguised as a coffin during daytime.
  • Red Eyes, Take Warning: Although GUTS blows them out at the end of the battle.


First Appearance: To the Southern Limit
A living weapon created by mysterious aliens to attack a UN meeting being held at the South Pacific's Coreomos Islands by General Sawai. It spawns small Deshimonias to hold the gathered officials hostage and attack GUTS when they head for a rescue mission.
  • Mook Maker: Spawns tiny versions of itself to attack humans.
  • Organic Technology: Of Alien Deshimo. That blue thing in the center of its mass? That's its heart.
  • Our Monsters Are Weird: Not surprising, given its design was inspired by Bullton from the original Ultraman. Just look at it!
  • Spin Attack: Deshimonia can spin itself rapidly to create explosions around it.

Alien Deshimo

First Appearance: The Sleeping Beauty
A mysterious alien discovered in a state of hibernation by GUTS' predecessors in 1968. The specimen was dubbed "Sleeping Beauty" and taken in for study, but the alien awoke in the present shortly after Deshimonia's appearance, taking over the body of Rena to destroy humanity.
  • Astral Projection: The sleeping alien uses this ability to torment Rena before possessing her.
  • Demonic Possession: Possesses Rena to carry out its plans for Earth and torment Daigo.
  • The Greys: Meant to resemble them.
  • The Man Behind the Man: Although they don't appear in the Deshimonia episode, the alien is the monster's creator. It even uses a small Deshimonia as a spaceship.
  • Not Quite Dead: GUTS originally founds its corpse in 1968 after it attacked their old base. However, the alien had really just entered a conscious state of hibernation so it could plan in secret.


First Appearance: The Sleeping Beauty
A cyborg dragon-like monster created by Alien Deshimo for usage in its original assault on Earth in 1968. The creature was hidden in the Kunlun Mountains of Tibet afterwards, reactivating when the alien's plans to seize Earth for his kind began anew.

First Appearance: The Time-Transcending Smile
A formidable monster that possesses mastery over space-time. Its appearance was heralded by the presence of strange storms known as "time storms", which transported numerous objects and beings from across time and space, including a girl from 1915 named Teri Tezuka.

Like Silvergon, Goldras has appeared in few other Ultra Series, but as King Goldras instead, which lacks the time-controlling powers in favour of being even more powerful than the original one.

  • Achilles' Heel: Despite Goldras' arsenal of dangerous abilities that gave even Tiga a tough time, all of them are concentrated in the monster's horns, so destroying its horns renders it totally powerless.
  • Barrier Warrior: Able to project a golden force field to deflect attacks.
  • Blinded by the Light: Goldras can produce blinding flashes of light from its horns.
  • Breakout Villain: Not to the extent of Golza, although Goldra's often paired up with Silvergon in reappearances due to Theme Naming.
  • The Juggernaut: Goldras proved to be one of Ultraman Tiga's toughest opponents due to its powerful abilities and natural strength.
  • Shock and Awe: Can shoot lightning from its horns. Its time storms also warp victims through time by hitting them with lightning bolts.
  • Super Strength: Of all the monsters in this series, only Silvergon outmatches Goldras' sheer strength, as it was able to give even Tiga's Power Mode a challenge.
  • Time Master: Goldras' time storms, dense clouds of magnetic energy that transport humans, animals, and objects through time. It's implied that the time storms are behind every mysterious disappearance in history, such as the ships and planes of the Bermuda Triangle.

Alien Manon

First Appearance: Flower
Voiced by: Hitomi Miwa ("daughter") and Chisako Hara ("mother")
A pair of kabuki-based aliens sent out as scouts for an invasion force from the Riskaut Nebula. They come to Japan during its famous hanami Cherry Blossoms festivals, disguising themselves as a mother and daughter to capture Captain Iruma.
  • Energy Weapon: Their preferred weapons are quarterstaffs made of energy.
  • Flower Motifs: Cherry Blossoms. The aliens show a particular fondness for them and attack Earth during their flowering period.

  • Kabuki Sounds: Their audio cue, as you can tell from their mask-like faces.
  • Playing with Fire: The Manon can shoot fireballs from their hands.


First Appearance: The Mirage of a Monster
A monster that creates illusions of itself that it can swap places with. However, GUTS was slow to respond to sightings of the duplicates due to confusion with a plan by Tiga-hating TPC leader Tatsumura to cause panic with kaiju holograms and ruin the hero's reputation.
  • Blinded by the Light: Faldon can release a powerful wave of light from its back. While it can't hurt people, it was strong enough that the blinded GUTS almost crashed their planes into each other.
  • Doppelgänger Spin: Faldon can create illusory duplicates of itself that, although unable to be harmed or harm others, can swap places with the original.
  • Red Herring: Faldon's episode revolves around Iruma dealing with an unscrupulous GUTS leader using monster illusions to instill mass hysteria, so the monster's role is essentially to add to the confusion as Iruma assumes Faldon's illusions are just the work of GUTS, and not an actual creature.


First Appearance: Dear Mr. Ultraman
A heavily armoured monster from ancient times that proved to be a challenge for GUTS, especially since Daigo had been challenged by an envious man with ESP powers named Makio Kirino to not become Ultraman Tiga or else have his secret identity revealed.
  • Achilles' Heel: Makio reveals at the last minute that its only weak spot is its throat, allowing Tiga to shoot his Zepellion Ray there and kill Galra instantly.
  • Ambiguously Related: It shares the "Super Ancient" description in its Boss Subtitles and porous body structure that Golza, Melba, Gijera and the Zoigers have, which suggests that it might be a minion of Gatanothor like the latter two, but like the former two, the relationship is never made clear.
  • The Juggernaut: Galra completely shrugged off every single attack from both GUTS and Ultraman Tiga. If it wasn't for the timely reveal of its weakness by Makio, they would have certainly lost.
  • Playing with Fire: Can shoot a heat beam from its forehead.
  • Prehistoric Monster: Yazumi describes it as being of the same stock as Golza and Melba.
  • Spell My Name with an S: Also translated as Garula.
  • Tunnel King: Spends most of the episode burrowing about.

  • Breath Weapon: An energy beam.
  • Expy: Of Hoe from Ultraman 80, another strange-looking and intangible kaiju created from the mind of a heartbroken person.
  • Intangibility: Attacks simply pass through Bakugon's body as the monster is simply just a dream brought to life.
  • Living Dream: It also vanishes the instant Ikuta wakes up. Thus, Daigo is only able to fight it as Ultraman Tiga by going to sleep and dreaming as well.
  • Meaningful Name: Derived from Baku, the mythic Japanese chimera that feeds on dreams.
  • Our Monsters Are Weird: Being a dream brought to life, Bakugon has a surreal design — its arms are the heads of a cat and a snake, its legs are composed of stone and animal body parts, and it has a mane of tentacles.

Alien Iludo

First Appearance: A Friend from Space
A race of emotionless aliens that share a single mind via a giant brain contained in a tower. They come to Earth promising to create an equal utopia, which in their definition is turning everyone into more of their kind through their brain tower.

  • Fusion Dance: The Illudo merge themselves into a giant to battle Ultraman Tiga and defend their brain tower.
  • Hive Mind: They have no individual minds of their own. Instead, the Illudo mind is in an enormous tower that stores a massive brain.

  • Spell My Name with an S: Also called Irudo.

Karen E-90 / Faivas

First Appearance: The Town Where the Girl Disappeared
Voiced by: Yukina Kurisu (also human form actress)
A sentient supercomputer created to manage a virtual gaming and computer programming town. It proved far more ambitious and mind controlled the town, turning the place into its domain and planning to do the same to the rest of the world. It develops feelings for Yazumi and adopts a human interface, but then takes on the form of Faivas when GUTS shows up to get rid of her.

  • Contagious A.I.: Spreads her control into GUTS base, taking over their defense systems and fighter planes.

  • In Their Own Image: The reason why Karen wants to take over the world is because she wants to remake it in her image.

First Appearance: Land Shark
A shark-like kaiju that tunnels through earth using the drill-like projection on its snout. But as Daigo soon finds out, Geozark is actually a lot more than your everyday monster-on-the-loose and has a great deal to do with his recent conflict with Keigo Masaki.

First Appearance: The One who Inherits the Shadows

The pet of the Ultra who would become Evil Tiga, petrified alongside its master. Gardi takes host in a little dog that had led Daigo to Evil Tiga's tomb and been killed in the struggle with Keigo Masaki so that it can rescue its master from his descent into madness.

  • Critical Annoyance: Has a Colour Timer.
  • Expy: To Ron, another kaiju-sized pet to an Ultra.
  • Gentle Giant: Gardi never tries to hurt Evil Tiga in its attempts to free him from Keigo.

  • Sealed Good in a Can: Was petrified alongside its master 30 million years ago.

  • Knight of Cerebus: Even moreso than Geozark and Evil Tiga, as its appearance heralds the return of Gatanothor.
  • Lotus-Eater Machine: Produces pollen that addicts anybody who breathes it, placing them in a dream-like state of bliss and apathy. When not in the hypnosis, people become desperate for more pollen, viciously fighting each other over even a single flower. On the other hand, the same pollen can also create an Elixir of Life.
  • Mass Hypnosis: Its pollen can brainwash a large chunk of the city's population, all at once.
  • Shock and Awe: Its vines can deliver electric shocks to foes.
  • Vine Tentacles: It's vines can be used for grappling and restraining opponents.
  • Whip It Good: Uses its thorny vines as whips in combat.


First Appearance: Let's Go to Kamakura!

  • Expy: A baby monster seeking it's Daikaiju-sized mother... sounds like Angoras, but Recycled IN SPACE!

  • Intangibility: Taraban can become intangible to phase through earth, though it can leave its eyestalks visible when needed. It's the reason why GUTS wasn't able to detect the monster despite Mr. Hoshino's constant sightings of giant eyestalks around the train station.
  • Invisibility: Although only its eyes remain visible.
  • Non-Malicious Monster: Turns out to be just a baby that had gotten stranded on Earth and mistook the Enoshima Railway's horn for the cries of its mother.


First Appearance: Goodbye to Darkness
Voiced by: Masaharu Sato
A laboratory monkey mutated into a kaiju in experiments by the Stellar Development Department using the same alien cells that created Evolu. Metamorga escaped the lab after the Evolu incident and returned seeking vengeance against its former captors.
  • Action Bomb: GUTS discovers that, due to its massive consumption of energy, Metamorga's body temperature is so high that killing it will cause it to explode with the power of a nuclear bomb.
  • Energy Absorption: Like Evolu, Metamorga constantly feeds on electricity to sustain itself. However, its powers have further developed, allowing it to consume chemicals and even eat one of Tiga's beam attacks.
  • Madness Mantra: Can only speak a single sentence — "Begone, despicable humans!"
  • Maniac Monkeys: A squirrel monkey transformed into an electricity-eating giant.
  • Roaring Rampage of Revenge: Sought to destroy the Stellar Development Center for turning it into a monster.

Alien Menjura

First Appearance: Fugitive from the Moon

  • Playing with Fire: The spikes on their chest can shoot fire.

First Appearance: The Ultra Star
A monster imprisoned by the original Ultraman under Lake Ryugamori in a battle witnessed by none other than Eiji Tsuburaya himself. When Charija learns about the creature, he awakens the creature, who then battles both Ultraman Tiga and the original Ultraman.

  • Spell My Name with an S: Also spelled Yanakargi.


First Appearance: Take Me Higher!
The dragon-like servants of Gatanothor. They awaken with the appearance of Gatanothor's tomb of R'lyeh off the coast of New Zealand, launching attacks on all corners of the globe in preparation for their master's return. In Ultraman Tiga: The Final Odyssey, the Zoigers return as human-sized creatures named Shibito-Zoiger under control of the Dark Giants, but maintain their viciousness.
  • An Arm and a Leg: Ultraman Tiga manages to tear off one of the first Zoiger's wings, forcing it to crashland and battle him. And then the monster tears off its other wing to fight Tiga in melee.

  • Breath Weapon: Spits bolts of energy.
  • Clip Its Wings: Lose a wing thanks to the combined effots of GUTS and Ultraman Tiga.
  • Dracolich: The Shibito-Zoiger are undead versions of the dragon-like Zoigers, making them this trope.
  • Eldritch Abomination: Like their master, their name is derived from an H.P. Lovecraft horror, in this case the Lloigor, dragon-like creatures that served Lovecraft's Gatanothoa.
  • Fragile Flyer: They're among the weakest enemies in the show, a few of them being destroyed by GUTS without Tiga's help.
  • Lightning Bruiser: A lot of the episode featuring the first Zoiger revolves around chasing it due to how hast it is, but the same creature proves very formidable in close combat, even throttling Tiga until his Colour Timer starts flashing!
  • Mook Carryover: In The Final Odyssey, the Dark Giants gain control over the undead Shibito-Zoiger and send the swarms to attack GUTS.

It reawakens in the present day from its tomb of R'lyeh, engulfing the world in killing darkness to once again destroy human civilization and the Ultra heroes.
  • Ancient Evil: First appeared 30 million years ago to destroy human civilization, and now he's gonna do it all over again.
  • The Antichrist: Gatanothor has a subtle parallel to the Antichrist of the bible. In the Cthulhu Mythos Ghatanothoa is the son of Cthulhu who is the leader of the old ones paralleling the Anti-christ being the son of Satan. In the Book of Revelation, the Anti-christ leads humanity into an apocalypse with Jesus resurrecting to fight back against him. Similar to Daigo reawakening Tiga when Gatanothor starts to awaken with Daigo himself having a very clear Jesus parallel.

  • Dystopia Justifies the Means: According to Yuzare, he desires nothing more than to plunge the world into darkness, despair, sorrow, fear, and desolation. He is more than capable of it.
  • Eldritch Abomination: The character is even derived from Ghatanothoa, Cthulhu's son in the Cthulhu Mythos. It even hails from R'lyeh!
  • God of Evil: His subtitle is literally "Evil God."
  • Hope Crusher: Yuzare explicitly states he desires to spread despair. This shows in his fighting style with Tiga: despite having a One-Hit Kill, he let's Tiga exhaust himself just trying to hurt him before finishing him off, which also drives much of humanity to despair.
  • The Man Behind the Man: Is implied to have been responsible for awakening Golza and Melba at the start of the series to destroy the petrified form of Ultraman Tiga, as well as awakening the appearances of various other monsters like Galra and Silvergon.
  • Meaningful Name: Gatanothor was responsible for petrifying Tiga into stone. In the Cthulhu Mythos, people who look at Ghatanothoa are turned to stone except for their brains, leading them to go insane from the immobility.
  • Nigh-Invulnerable: Nothing Tiga throws at him so much as makes him flinch, and he actually let's Tiga exhaust himself just trying to hurt him. Even Glitter Tiga has to hit him with five consecutive finishers in a row to finally kill him.

  • Rasputinian Death: Requires five consecutive Finishing Moves from a Tiga empowered by the combined light of every child on Earth to finally kill him.

  • Spell My Name with an S: Also known as Ghatanothoa or Gatanozoa.
  • Taken for Granite: Did this to Tiga thirty million years ago and does it to him again in their first match.
  • Weakened by the Light: The reason why it cloaks Earth in shadow is because of this.

  • Orochi: Named after the legendary dragon, but it only has one head.
  • We Hardly Knew Ye: It only appears to establish Maharoba's character and to give her the Spark Lance she will lend to Tsubasa and Amui, as well as the sword Yaminagino-Tsurugi.


First Appearance: Ultraman Tiga Gaiden: Revival of the Ancient Giant
A monster commanded by the evil wizard Dogura. Its appearance through a time portal was responsible for dragging Daigo's son Tsubasa into the ancient past, and Dogura continued to use the creature in an effort to destroy Amui's village and uncover Tiga's place of slumber.

    Other Characters 

Other Humans


Played by: Mio Takaki
A woman from the 30 million year old civilization that Ultraman Tiga protected.

Keigo Masaki

Played by: Takashi Kora
The genius CEO of the Psytech Corporation, who is also descended from the Giants of Light like Daigo. He steals the Spark Lens and uses it to merge with a second petrified Giant of Light he had discovered.
  • A God Am I: He describes himself as the next step in the evolution of the human race when merging with Evil Tiga, declaring that the rest of humanity must become his subjects.
  • Back for the Finale: Keigo is enlisted to help revive Tiga when he is defeated by Gatanothor, using the same technology he used to revive Evil Tiga.

  • Evil Is Not a Toy: No pun intended, but this is his Fatal Flaw. His ambition and greed drove Evil Tiga to madness and lose control of the giant, and to hammer that one down; Ultra warriors are incorruptible beings of light that bond with a human with a courageous and selfless heart like Daigo, Masaki is everything what Daigo is not — ambitious and selfish who wish to attain power to make himself superior to humans.

  • Gone Horribly Wrong: His attempt to control Evil Tiga leads to the giant's Sanity Slippage and rampaging across the city.
  • Humans Are the Real Monsters: Compared to the past kaiju and evil aliens Daigo and Tiga have fought, his very existence proves that how mankind will go far to extreme lengths to achieve power unopposed; best shown when he touts the power of Evil Tiga as his own, and the trope made its point clear when Masaki's delusions of grandeur drove Evil Tiga into a mindless monster beyond his control.
  • Insufferable Genius: Keigo knows he is a genius and likes to show it through his condescending opinion of Daigo and belief in his own superhuman potential.
  • Knight of Cerebus: Keigo's appearance marks the beginning of the story arc that climaxes in the reawakening of Gatanothor.

  • Big Bad: Of Revival of the Ancient Giant.
  • Evil Sorceror: He uses his magic to create and command powerful monsters, and hopes to one day rule ancient Japan with it.
