Ultraman Ace

https://static.tvtropes.org/pmwiki/pub/images/ultraman_ace.png

Voiced by: Goro Naya (series; stock grunts afterwards), Keiji Takamine (Ultraman Mebius onwards)
The star of his eponymous series, Ultraman Ace came to Earth to combat the threat of Yapool and his Choju. Unlike the first three Ultra Heroes, he took the bodies of two individuals — a man named Seiji Hokuto and a woman named Yuko Minami — to be his hosts after the two were killed in Velokron's first assault. Ultraman Ace would soon go on to recur in many other series, such as Ultraman Taro and Ultraman Mebius.
  • Bash Brothers: With Ultraman Taro, whom he is actually the adopted brother of.
  • Blinded by the Light: Can fire stunning flashes of light from his Color Timer by placing his hands over it.
  • Chest Blaster: His Timer Shot, fired from his Color Timer, as its name suggests.
  • Conveniently an Orphan: His father was killed a long time ago, so he was instead raised by his father's friend the Father of Ultra.
  • Finishing Move: His signature attack is the Metallium Ray.
  • Hand Blast: Can fire various lesser versions of these.
  • Playing with Fire: Able to shoot jets of flame from his hands by putting them together.
  • Rings of Death: His Ultra Guillotine sometimes manifests as this. Other times, it appears as a long crescent-shaped blade of energy.
  • Spell My Name with an "S": Also known as Ultraman A in older materials, as his series' title card spells it that way.
  • Sword Beam: Variant. Ace doesn't use a sword, but his Ultra Guillotine functions in the same way as one, chopping up Choju into many pieces with gruesome efficiency.
  • Warrior Poet: Literally. According to Expanded Universe materials, Ace is a poet back on the land of light, though given he rarely talks in a way humans can understand, we don't really see this.

Father of Ultra

https://static.tvtropes.org/pmwiki/pub/images/ultra_father.png

Voiced by: Tetsuya Kaji (series), Isamo Tamagawa (series; human form), Shinya Kashima (Ultraman Taro), Tokuma Nishioka (Ultraman Mebius onwards), Masao Nakasone (series with low-pitch grunts)
The Father of Ultra (or Ultra Father) is the supreme commander of the Space Garrison, the intergalactic peacekeeping force that all the Ultra Heroes belong too. A veteran of many wars, the Father of Ultra is one of the most powerful residents of the Land of Light. He has become a major part of the franchise mythos, such as being the literal father of Ultraman Taro.
  • A Father to His Men: Part of the reason why he earned his name of "Father of Ultra".
  • Action Dad: He's a metaphorical father to Ultraman Ace and many other heroes, but also the literal dad of Ultraman Taro.
  • Authority Equals Asskicking: Alien Hipporito was able to take out all the Ultra Brothers, but even while weakened due to various things, the Father of Ultra was throwing him around like a rag-doll for most of their fight, and left him weakened enough for Ace to finish off.
  • Badass Beard: One of the few Ultras to sport facial hair; in this case, sideburns.
  • Badass Cape: He often wears one, as they're a status symbol on M78. He can use it in combat to great effect as well.
  • Badass Santa: His human form is a street corner Santa Claus.
  • Big Good: The leader of the Ultra Space Garrison, with only Ultraman King being more important than him. But whereas King is largely a hermit, the Father is more actively engaged, having fought some of the Ultra Series' most powerful villains to a standstill and assigns all the Ultras on missions or to their tours of duty on Earth.
  • Cool Old Guy: He's the grandfather of Ultraman Taiga, one of the newtest Ultras from the Reiwa Era.
  • Impossibly Cool Weapon: His Ultra Array, a dumbbell-shaped object capable of emitting blinding flashes of light, as he used on Alien Hipporito and later Jashrine.
  • Special Person, Normal Name: In Mega Monster Battle: Ultra Galaxy Legends, his name is revealed to be Ken, although only his Evil Former Friend Ultraman Belial ever calls him that.
  • Horned Humanoid: His great horns are a rarity amongst Ultramen, though his son Taro inherited them.
  • Team Dad: To the Ultra Brothers, which happen to include his son and adopted son.
  • Worf Had the Flu: Lost to Alien Hipporito, barely, because he was weakened by various things at the time. We find out in later series that had the Father been at his full power, Alien Hipporito would've been squashed like a bug.

    Monsters and Aliens 

Yapool

https://static.tvtropes.org/pmwiki/pub/images/yapool.png

First Appearance: Shine! The Five Ultra Brothers!
Voiced by: Hirofumi Takada
The series' Big Bad, Yapool is an immortal entity from another dimension who creates bizarre but powerful monsters called Choju (Japanese for "Super-Beast") to destroy the world. He is a cruel and hateful being who enjoys tormenting humans and Ultras alike through his numerous powers and despises the heroes of Nebula M78 above all else.

As a sworn enemy of the Ultramen and the very first Big Bad of the Ultra Series, Yapool is considered one of the franchise's best villains and has antagonized not only Ultraman Ace, but many later Ultra heroes like Ultraman Mebius and Ultraman Ginga.


  • Archenemy: While he hates all the Ultramen with burning passion, he reserves the most for Ultraman Ace.
  • Barrier Warrior: Can create force fields around himself at will.
  • Big Bad: Of Ultraman Ace, as he creates the Choju that Ace has to stop. He's also notable for being the first one created for the Ultra Series.
  • Breakout Villain: Yapool's also popped up in several other series, such as Ultraman Taro and Ultraman Mebius, albeit suffering from Demoted to Dragon and sometimes Villain Decay.
  • Demonic Possession: One of his favourite abilities is to take over the bodies of humans or his own Choju to control them.
  • Dimension Lord: He rules his very own dimension, a sort of formless place of bright swirling colours. Travel between this dimension and ours can be done by him and all Choju, which is seen as the sky shattering like glass.
  • Eldritch Abomination: Yapool normally appears as a formless mass, though at one point, he assumes a physical "Giant Yapool" form to battle Ace one on one. Later series that feature Yapool typically have him use this form.
  • Energy Being: His normal form,.
  • Evil Is Hammy: In most appearances.
  • Evil Sorcerer: Although he usually ceates Choju through science, Yapool has displayed a knack for magic, as seen with the creations of Cowra, Mazarius, and Aprasall. Additionally, he's been able to revive others from the dead like Bemstar in Ultraman Taro and Juda in Ultra Fight Victory.
  • Hand Blast: Can shoot powerful energy beams from his hands in physical form.
  • Humanoid Abomination: His "Giant Yapool" form.
  • I Am Legion: Yapool sometimes refers himself as "we". Initially it was because Yapool was a race of beings called the Yapool (with his Giant Yapool form being a Fusion Dance), but in Ultraman Mebius, this was retconned into being the collective consciousnesses of an entire alien race.
  • Mad Scientist: As the creator of the Choju, he specializes in using highly advanced technology create (or mutate) all sorts of deranged monsters to antagonize Ultra heroes.
  • Manipulative Bastard: Loves to mess around with the emotions of heroes (both ultras and humans). To him, playing with the emotions of humans is extremely entertaining because he finds them to be pathetic creatures.
  • Mind over Matter: Has potent psychic powers, including telekinesis.
  • The Power of Hate: Yapool claims in Ultraman Ginga that this is the source of his immortality. He literally wills himself back to life with his own hatred for the Ultras every time they defeat him.
  • Resurrective Immortality: Thanks to The Power of Hate, Yapool will always return to life no matter how many times the Ultras defeat him.
  • Right Hand of Doom: In his physical form, his right arm is a vicious blade.
  • Shapeshifter: Likes to take the form of other beings to sneak around unnoticed and befriend others in order to backstab them at the last moment.

Velokron

https://static.tvtropes.org/pmwiki/pub/images/velkron.png
Click here  to see the second Velokron

First Appearance: Shine! The Five Ultra Brothers!
The first Choju that Yapool unleashes upon Earth, where it quickly showed off the sheer power of Choju by completely decimating an entire fleet of Earth Defense Organization fighters, leading the the establishment of TAC. A second and drastically redesigned Velokron appeared in a later episode when Yapool (disguised as a dentist) placed a hallucinatory curse on Hokuto.

As the first Choju of the Ultra Series, Velokron has made numerous reappearances and has since become one of the series' iconic Choju trio alongside Vakishim and Doragory.


  • Achilles' Heel: The inside of its mouth.
  • Art Evolution: The second Velokron design used in Velokron's reappearance in this series (as well as in Ultraman Taro) has a longer tail, is green instead of black, and has the back coral across the whole back instead of just the shoulders. Justified by the fact that Yapool created a completely new Velokron instead of resurrecting the original.
  • Breakout Villain: As the very first Choju to appear in the Ultra Series, Velokron is Ultraman Ace's most iconic enemy.
  • Breath Weapon: A stream of flames in many appearances. The second Velokron also breathes weakening bubbles.
  • Chest Blaster: The second Velokron fires its missiles solely from its chest (and mouth).
  • Hand Blast: Velokron can fire a huge variety of energy bolts and missiles from its hands, as well as a binding rope of energy.
  • Macross Missile Massacre: Velokron's main power is the innumerable supply of missiles from its coral body that it launches en masse at enemies.
  • Mix-and-Match Critters: Coral was mixed with a space monster by Yapool to create Velokron.
  • Our Monsters Are Weird: Pretty much all Choju are an example, and Velokron is just the first taste — a dinosaur made of coral that shoots missiles from its body.
  • Power Trio: With Vakishim and Doragory.
  • Shock and Awe: Several of Velokron's appearances have displayed the ability to shoot lightning bolts from various places like the hands and nose.
  • Spell My Name with an "S": Also called Verokron.
  • Starter Villain: The very first Choju in the Ultra Series and thus Ultraman Ace's first enemy.

Chameleking

https://static.tvtropes.org/pmwiki/pub/images/chameleking_2.jpg

First Appearance: Surpass the Choju
A dragon-chameleon Choju that Yapool created from an ancient monster that had ravaged Atlantis. The creature hatched from a massive self-aware egg that Yapool planted in a construction site to be discovered by humans.
  • An Arm and a Leg: Ace tears off Chameleking's wings during the battle.
  • Blow You Away: As a flying Choju, it creates massive hurricane-forced winds by flapping its wings.
  • Breath Weapon: A blast of misty white gas, though we never get to see what it does exactly.
  • Giant Flyer: In egg form and adult form.
  • Our Dragons Are Different: Strongly resembles a western-style dragon, though it also borrows chameleon motifs as seen in its name and eyes.
  • Make My Monster Grow: Chameleking's egg grows in size by absorbing matter, including people, an airplane, and a second egg of an alien species of pterosaur that Yapool sends out, which allows the monster to hatch out as an adult.

Vakishim

https://static.tvtropes.org/pmwiki/pub/images/vakishimm.png

First Appearance: Burn! Choju Hell!
A Choju that Yapool possessed himself in an effort to take matters into his own handsnote . The monster then impersonate a small boy and go on a murderous rampage, razing down a village and killing family members.

Vakshim has reappeared many more times in the Ultra Series as the second of the iconic Choju trio (along with Velokron and Doragory). Often, Vakshim is possessed by its master Yapool in many of its reappearances in homage to the famously disturbing events of its debut episode.


  • Acrofatic: Despite Vakishim's tubby design, it is very capable of impressive jumps and swift reflexes.
  • Breakout Villain: One of Ultraman Ace's most iconic enemies and the first of the Choju trio return in Ultraman Mebius.
  • Dead Person Impersonation: The boy that it takes the form of to slaughter people is revealed at the end to have died several years ago.
  • Hand Blast: Is able to shoot laser bullets from its hands (though similar projectiles come from its nostrils).
  • Horn Attack: The horn can be launched as a targeting missile. Depending on the series, Vakshim can regenerate the horn as well.
  • Mix-and-Match Critters: Yapool created Vakishim by mixing up a caterpillar with an extraterrestrial creature.
  • Off with His Head!: Its fate.
  • Playing with Fire: Can shoot a stream of flame from its hands.
  • Power Trio: With Velokron and Doragory.
  • Spell My Name with an "S": Sometimes more literally translated as Bakushimu.

https://static.tvtropes.org/pmwiki/pub/images/garan_1_5.png

First Appearance: 30 000 Year Choju Appears
A prehistoric fish transformed into a Choju. Garan's life is connected to an obsessive manga artist named Kuri Mushitaro who had made a deal with Yapool to win Mikawa's heart by any means. However, any pain received by Garan is felt by Mushitaro as well.

Aribunta

https://static.tvtropes.org/pmwiki/pub/images/aribunta_victory.jpg

First Appearance: Giant Ant Choju vs. Utra Brothers
An ant-like Choju given to Giron-Man as a battle companion by Yapool, assisting the alien in tunneling out a massive cave network underneath Tokyo to strike from below. Aribunta is not as well-known as Vakishim, Velokron, or Doragory, but has become something of an Ensemble Dark Horse, earning it reappearances in series like Ultra Fight Victory and Ultraman Orb.
  • Big Creepy-Crawlies: Based on ants. Furthermore, it's implied that Yapool took an ant kaiju previously encountered by another defense team and further mutated the creature as TAC apparently has records of giant ant monsters.
  • Breakout Villain: In the 2010s, Aribunta increasingly became one of these, as it became used in favor of traditional choices like Lunatyx and Vakishim.
  • Breath Weapon: Aribunta can spray out a stream of nasty acid from its mandibles. Dissolved an entire subway of people in its first appearance, leaving only skeletons.
  • Meaningful Name: Aribunta's name is a combination of "ari" (Japanese for "ant") and "maranbunta" (a Latin American name for army ants).
  • Playing with Fire: Can shoot streams of fire from its claws.
  • Put Their Heads Together: With Giron-Man, which is how Ultraman Ace and Zoffy kill them.
  • Tunnel King: A very capable burrower, creating an enormous complex of tunnels underneath the city to be used as Giron-Man's hideout.

Giron-Man

https://static.tvtropes.org/pmwiki/pub/images/giron_man.png

First Appearance: Giant Ant Choju vs. Ultra Brothers
Voiced by: Ritsuo Sawa

  • Beneath the Earth: Giron-Man's species hail from underground, so he decides to turn the entirety of Tokyo's underground into his lair.
  • Dishing Out Dirt: Was able to create massive stalactites and stalagmites from the ground in order to make a cage for Ace.

  • Power Pincers: Able to fire laser bullets from his pincers.
  • Put Their Heads Together: Zoffy and Ace kill him and Aribunta with this method.
  • Shock and Awe: Was shown to be able to electrify the prison of stalactites and stalagmites he created to torture Ultraman Ace.
  • Teleport Spam: Uses this ability to elude Ace when the hero pursues him through his cave network.

Brocken

https://static.tvtropes.org/pmwiki/pub/images/brocken_2.jpg

First Appearance: Pursue the Mystery of the Transformation Choju
A bizarre four-legged Choju sent by Yapool to infiltrate a spaceship and possess one of the astronauts aboard, Koyama. On Earth, the Brocken-controlled Koyama blends in with his family, intent on waiting for the perfect opportunity to strike at TAC.
  • Breath Weapon: Snorts fire.
  • Demonic Possession: Brocken takes over the body of an astronaut named Koyama. However, the possessed victim has an eye and a mouth on each of his hands and will cast no shadow, which his son discovers and reports to TAC.
  • Eyes Do Not Belong There: Look closely at those two tails. Those are actually extra eyes on long stalks. Additionally, those it possesses have one eye on their hands in mimicry of the eyestalks.
  • Mix-and-Match Critters: Yapool created Brocken by mixing an alligator and with some kind of alien monster.
  • Off with His Head!: Ultraman Ace kills him by chopping it off, along with his hands and and eyestalks.
  • Shock and Awe: Shoots lightning from its twin eyestalks and mouth-hands.
  • Too Many Mouths: Brocken's hands are mouths — something that transfers to those it possesses.

Doragory

https://static.tvtropes.org/pmwiki/pub/images/doragory.png

First Appearance: Kaiju vs. Choju vs. Seijin
A moth-based Choju sent by Yapool to assist Alien Metron Jr. in preventing TAC from successfully stopping a planet-sized asteroid called Goran from catastrophically colliding Earth in a less than a week.

Doragory is the third and final introduced of Ultraman Ace's iconic Choju Power Trio (the other two being Vakshim and Velokron). Like them, Doragory has returned many times in the Ultra Series to menace new generations of heroes.


  • Breakout Villain: Along with Vakishim and Velokron, Doragory is considered to be one of Ultraman Ace's most iconic foes and frequently appears against other Ultra heroes.
  • Breath Weapon: Fire, red lightning, or purple orbs of energy depending on the series.
  • Disproportionate Retribution: Muruchi's punishment for accidentally ramming into Doragory? One of the most gruesome deaths in the franchise ever.
  • Dumb Muscle: The greatest of the Choju Power Trio in terms of sheer physical strength, able to rip weaker monsters into shreds, but also less intelligent than the other two.
  • Eye Beams: Fires red lightning bolts from its eyes.
  • Hand Blast: Doragory is able to fire energy missiles from its hands.
  • Kick the Dog: Kills Muruchi very horrifically, even though the kaiju only wanted to help Metron Jr. and Doragory.
  • Macabre Moth Motif: Although the only obvious insectoid quality in Doragory is the compound eyes, Doragory is based on a poisonous moth as evidenced by its Boss Subtitles "Moth Super-Beast".
  • Off with His Head!: His death.
  • Power Trio: With Vakishim and Velokron.
  • Spell My Name with an "S": Doragoris and Dragory are also used.
  • Super Strength: Enough to rip weaker monsters to shreds.
  • Torso with a View: Ultraman Ace manages to punch a hole straight through Doragory in their final fight.
  • Villain Team-Up: With Alien Metron and Muruchi (well, briefly)

Alien Metron Jr.

First Appearance: Kaiju vs. Choju vs. Seijin
The son of the first Alien Metron. Metron Jr. was an agent of Yapool sent by the evil entity alongside Doragory to sabotage a TAC operation to destroy the Goran asteroid and save Earth from a colossal cataclysm.
See Ultraseven

  • Art Evolution: Metron has a more simplistic orange-and-blue colour scheme with less yellow accents. Additionally, he has a visible mouth. Justified by the fact that he's a different individual from the original Alien Metron.
  • Avenging the Villain: He's the son of the original Alien Metron working with Yapool to avenge his father's death on Earth.
  • Blinded by the Light: Unlike other versions of Alien Metron (including his old man), Metron Jr. can create explosive flashes of blinding light from his hands.
  • Demonic Possession: The only incarnation of Metron to do this, which he does to infiltrate TAC's base.
  • Half the Man He Used to Be: His fate.
  • Hand Blast: Able to shoot stun bolts from his finger tips — an ability the original Alien Metron and all subsequent incarnations of the alien have never displayed.
  • Teleport Spam: Yet another ability not seen in other incarnations of Alien Metron (Alien Metron doesn't have a lot of unique powers, okay?).
  • Villain Team-Up: With Doragory and Muruchi.

Muruchi

First Appearance: Kaiju vs. Choju vs. Seijin
A kaiju previously encountered by Ultraman Jack that suddenly appeared while Ultraman Ace was battling Doragory and Metron Jr and decided to participate against the Ultra hero. However, Muruchi angered Doragory when Ace dodged an attempted charge by the fish-like kaiju, and Doragory proceeded to rip Muruchi apart, leaving the monster to die a painful death.
See Return of Ultraman

  • Cruel and Unusual Death / Family-Unfriendly Death: Doragory dismembers Muruchi very graphically on-screen and uncensored, tearing its jaw and leg clean off.
  • Giant Space Flea from Nowhere: Muruchi's appearance is as unexpected as it is unexplained, still baffling fans to this day.
    • The Ultraman Encyclopedia tried to rectify this by stating it to have hatched from an egg laid by the original monster from Return of Ultraman (except the original Muruchi was hibernating in an alien spaceship for almost the entirety of its episode, so when did it lay the egg?).
    • Fans have speculated that the first Muruchi actually survived its fight with Jack and then awoken during Ace's battle with Doragory and Metron Jr. (even though the creature was clearly Specium'd on-screen).
  • Villain Team-Up: With Metron and Doragory until Muruchi rubbed Doragory the wrong way.
  • The Worf Effect: Muruchi's quick and brutal death at the hands of Doragory served to showcase how much more powerful Choju were than the standard kaiju of the previous series.

Gammas

https://static.tvtropes.org/pmwiki/pub/images/gamas.png

First Appearance: 10 000 Choju! Surprise Attack Plan!
A bizarre Choju that made itself a hassle for TAC with its ability to jump in and out of reality by hiding in photographs, particularly those of a plucky young female reporter named Junko who had taken a photo of the monster during its first battle with TAC.
  • Breath Weapon: Spits explosive darts.
  • Bullet Catch: Was able to catch the missiles fired by TAC from their planes, and actually hurl them back at the aircraft.

  • Impaled with Extreme Prejudice: Gammas' fate.
  • Invisibility: One of its powers.
  • Our Monsters Are Weird: Even by the standards of this show, Gammas is one freaky beast.
  • Phantom Zone Picture: Gammas' signature ability is to hide inside photographs, allowing it to completely conceal itself from TAC and make surprise attacks as it wishes.
  • Spear Carrier: Yapool creates a two-headed spear for Gammas during its battle with Ultraman Ace.

Alien Antira

https://static.tvtropes.org/pmwiki/pub/images/achira_seijin_by_guigazone_d4qj74p.jpg

First Appearance: Battle! Ace vs. Hideki Goh!
Voiced by: Hirofumi Takada
Another alien agent in the service of Yapool. Antira took the form of Hideki Goh in an effort to hinder Hokuto against Zaigon and get away with it through Goh's reputation, as well as deceive Jiro Sakata, who is ecstatic to see his older brother figure/friend return.
  • Shapeshifter: Another of those Ultra Series aliens that specializes in turning itself into an evil version of the heroes. But rather than an Ultraman, Antira impersonates one of their human hosts, knowing that their good reputation with successor defense teams will allow him to get away with his attacks on Hokuto.
  • Spell My Name with an "S": Also called Achira.

Zaigon

https://static.tvtropes.org/pmwiki/pub/images/zaigon_0.jpg

First Appearance: Battle! Ace vs. Hideki Goh!
A rhinoceros-like Choju lent to Alien Antira by Yapool. Antira used Zaigon as a decoy for his plot to deceive TAC with the form of Hideki Goh by getting the Choju to attack Tokyo while he dealt with Hokuto and Minami.
  • Breath Weapon: Breathes fire.
  • Bull Seeing Red: Although based on a rhino, Zaigon is easily provoked by the colour red and Ultraman Ace even plays a bit of "matador" with the Choju.
  • Off with His Head!: How Ultraman Ace kills it.
  • Red Herring: Antira used Zaigon as one for TAC so they wouldn't pay attention to his attempts to kill Hokuto and Minami in his Goh disguise.
  • Rhino Rampage: Although he doesn't look tha part, Zaigon is modeled after rhinoceroses (with some bull thrown in). Case in point, its Boss Subtitles is "Rhino Super-Beast"

Unitang

https://static.tvtropes.org/pmwiki/pub/images/unitang_2.jpg

First Appearance: The Choju is Ten Women?
A Choju that was sent by Yapool to destroy TAC's new Choju-detecting radar system. Unitang has with ability to transform into 10 young women — an ability that it not only uses to stay out of TAC's sight, but to get the better of Hokuto and prevent him from becoming Ultraman Ace.
  • Breath Weapon: Breathes sticky webbing, though it also sprays the same stuff from its claws.
  • Horn Attack: Like Vakishim, Unitang can launch its horn like missile. It can also create explosions by flashing its horn.
  • I'm Melting!: Ultraman Ace defeats Unitang by dissolving it with acid.
  • Mind Control: In its 10 girls form, Unitang does this to Hokuto by placing a device on his neck.
  • Our Monsters Are Weird: This creatures is as off-the-walls bonkers as its ability to become 10 girls sounds, complete with some wacky moments between Hokuto and the women.
  • Pulling Themselves Together: Ultraman Ace finds this out when he chops Unitang to pieces.
  • Voluntary Shapeshifting: Can transform itself into 10 pretty, young, bike-riding women, who are able to do a Fusion Dance to turn back into their Choju form.

Sabotendar

https://static.tvtropes.org/pmwiki/pub/images/sabotendar_render.png

First Appearance: The Red Flower of Cactus Hell
A cactus Choju that hid from TAC by disguising itself as an ordinary-looking, insect-eating cactus that was then taken in by a boy who names it "Saburoten", unaware of its true nature. Sabotendar also made a brief appearance in Ultraman Taro.

Barabas

https://static.tvtropes.org/pmwiki/pub/images/barabass.png

First Appearance: Execution! The Five Ultra Brothers!
A powerful Choju sent by Yapool to overwhelm TAC while he lured Ultraman Ace and the rest of the Ultra Brothers to the planet Golgotha in order to capture them and prepare to have Ace battle his deadliest Choju yet — Ace Killer.
  • An Axe to Grind: Its left hand.
  • Blinded by the Light: Can create paralyzing flashes of light from the sword-horn on its head
  • Breath Weapon: Breathes fire.
  • Epic Flail: Its right hand.
  • Family-Unfriendly Death / Cruel and Unusual Death: Ace kills Barabas by first stabbing it with its sword and then punching the monster so hard its eyes pop from its sockets before tearing off its mace hand and using it to chop off its head!

  • Horn Attack: Barabas has a sword-shaped horn on its head that it can shoot like a missile or use as a blade.
  • Meaningful Name: Barabas is named after Barabbas, an insurrectionary mentioned in the Bible as having been freed by Pontius Pilate over Jesus Christ at his crucifixion.
  • Mix-and-Match Critters: Yapool created Barabas by combining a vicious extraterrrestrial monster with a swallow tail butterfly.
  • Prehensile Tail: Barabas has a three-pronged tail that it uses to strangle Ace in their battle.
  • Spell My Name with an "S": Has also been spelled Baraba, Barabbas, and Barabba. Additionally, some merchandise have mistakenly called the monster Varava due to the "B-V" confusion that exists in the Japanese language.

Ace Killer

https://static.tvtropes.org/pmwiki/pub/images/ace_killerr.png

First Appearance: The Five Stars that Scattered Through the Galaxy
A humanoid Choju created by Yapool for the sole purpose of destroying Ultraman Ace. Ace Killer was given the combined powers of Ultraman, Zoffy, Ultraseven and Ultraman Jack when Yapool successfully lured them to the planet Golgotha, where they were crucified and drained of their power.

Ace Killer has reappeared many times in the Ultra Series. However, the wicked Choju has been constantly remade by Yapool and the show's producers to defeat the incumbent Ultra hero with the powers of the Ultramen, so Ace Killer has gone under several renames like Mebius Killer and Victory Killer.


  • Breakout Villain: Not as much as Vakishim, Velokron, or Doragory, but Ace Killer is quite a popular Choju often pitted against later generations of Ultra heroes.
  • Cyborg: You can't really tell from looking at it, but Ace Killer is confirmed by magazines from the period to be heavily robotic. Specifically, it was modified from an alien corpse that Yapool discovered on Golgotha and brought back to life. Whether subsequent Ace Killers featured in the franchise are also cyborgs - or all-out robots - hasn't really been explained.
  • Evil Knockoff: Meant to resemble a demonic Ultraman, as it specifically exists to kills Ultra heroes.
  • Glowing Eyes of Doom: Its only real facial features are its bright green eyes.
  • The Juggernaut: Since it was made specifically to kill Ultras, Ace Killer is highly resistant to all but the most powerful of Ultraman beam attacks
  • Names to Run Away from Really Fast: Never mess with a Choju with the last name Killer.
  • Noun Verber: Victory, Mebius, Ace. You name the Ultra, Killer will be upgraded to defeat it.
  • Power Copying: Ace Killer has no powers of its own (asides the usual Choju abilities like dimensional travel), but instead has the powers of various Ultramen, usually the one it's been designed to slay, but in its original appearance, Yapool gives it the powers of the first four Ultramen against Ace's.
  • Power Parasite: Steals the powers of the first four Ultra Brothers by absorbing them through its "Colour Timer".
  • Right Hand of Doom: The huge claws on the left hand.
  • Sai Guy: Ace Killer wields sai in its right hand. However, it is never seen in any later appearances.
  • The Worf Effect: Yapool gets to demonstrate this by siccing a robot duplicate of Ultraman Ace onto Ace Killer, who proves completely immune to the Metallium Ray and soon destroy the robot with the powers of Zoffy and Ultraman Jack.

King Crab

https://static.tvtropes.org/pmwiki/pub/images/king_crab.jpg

First Appearance: Curse of the Black Crab
A crustacean-based Choju that suddenly appeared out of the sea while Kono was taking a vacation to visit his niece. King Crab has the ability to transform into an ordinary horseshoe crab to hide from TAC.
  • Giant Enemy Crab: Doesn't look much like one, but is based on crustaceans and horseshoe crabs (although the latter are actually more closely related to spiders).
  • Making a Splash: King Crab can spray extremely slimy seawater that is capable of damaging power lines.
  • Playing with Fire: Can shoot a jet of flames from its forehead.
  • The Power of Hate: Yapool created King Crab by using an ordinary crustacean's hatred for humans.

A Choju created from a friend of Yoshimura from Okayama named Takai, who was cursed by Yapool (using a sacred cattle nose ring that Takai stole) into becoming a half-bull hybrid and eventually a giant monster.
  • A Load of Bull: It's a cow Choju; what did you think?
  • Bull Seeing Red: Ultraman Ace plays a bit of "matador" with this guy during their fight.
  • Horn Attack: Other than the obvious goring attacks, Cowra can shoot a purple laser from between its horns.
  • Master of Illusion: Can create hallucinations to confuse enemies.
  • Was Once a Man: Used to be an ordinary farmer named Takai, who was first turned into a Minotaur-like creature by Yapool before becoming Cowra. This is due to the curse Yapool placed on a nose ring Takai stole from a sacred hilltop, which Cowra wears on its arm.

Hotarunga

https://static.tvtropes.org/pmwiki/pub/images/hotarunga_esu.jpg

First Appearance: Ghost Story: The She-Devil of Firefly Field

  • Blinded by the Light: Being a firefly-based monster, Hotarunga can emit stunning flashes of light from its body to incapacitate opponents.
  • Hollywood Acid: Hotarunga can spray a highly acidic mist from its forehead. The mist also has explosive ad suffocating properties for a good measure, but TAC blasts the monster's forehead to give Ace a much-needed upper hand.

Black Pigeon

https://static.tvtropes.org/pmwiki/pub/images/pigeon_i.jpg

First Appearance: Lend Me the Pigeon
Once a boy's pet homing pigeon named Kajiro, Black Pigeon was created by Yapool from the poor bird to bring terror from above. However Yapool quickly found out that Black Pigeon was difficult to command as Kajiro's former owner tried to bring his pet back to its senses.
  • Achilles' Heel: Due to originally being a pet, Black Pigeon is pacified by the sound of its owner's pigeon whistle, which ends up hindering Yapool's attempts to get Black Pigeon to do his bidding.
  • Alas, Poor Villain: As an ordinary animal beloved by a child, Black Pigeon's death actually saw little celebration as Kajiro remains dead after the Choju turns to normal upon defeat.
  • Attack Reflector: Black Piegon is able to bounce beam attacks of its body by using its own chest.
  • Blow You Away: As with most flying monsters, Black Pigeon can create huge gales from the flaps of its wings.
  • Breath Weapon: Asides from the jets of flame common to Yapool's Choju, Black Pigeon can spit some kind of white paralytic substance, which might be a mutated form of pigeon milk.
  • Feathered Fiend: Being a pigeon monster, though somewhat more sympathetic due to the circumstances of its creation and defeat.
  • Giant Flyer: As to be expected from a bird Choju.
  • Spike Shooter: Black Pigeon's got a single massive spike on its chest that can be fired like a missile.
  • Tragic Monster: One of the few Choju to be treated with pity due to its connection with its former human owner. The fact that it doesn't get turned back into Kajiro to live the rest of its days as normal makes it even sadder.

King Kappa

https://static.tvtropes.org/pmwiki/pub/images/king_kappa_i.png

First Appearance: Mystery of the Kappa's Residence
A Kappa-like Choju that disguised itself as a swimming pool that would capture kids and turn them into kappas by eating their navels. It was assisted by a pair of Yapool-sent androids disguised as a couple who owned the pool to lure Hokuto in to investigate.

Space Mask

https://static.tvtropes.org/pmwiki/pub/images/space_mask.png

First Appearance: Yapool, Demon of Revenge
Voiced by: Tomiotto Tomikawa (also human form actor)
Yapool's newest extraterrestrial minion, coming to Earth in the disguise of a kindergarten teacher named Jiro Sakai. Space Mask had his students build a statue of a monster while he befriended TAC to spy on Hokuto and Minami.
  • Bitch in Sheep's Clothing: He makes himself seem like a kind and lovable teacher who wants to let children have fun and makes friends with TAC (even inviting them to visit his students), but as an agent of Yapool, his friendliness is all part of a dire scheme.
  • Came from the Sky: He arrives on Earth in the form of a comet that is reported to TAC, only for him to kill the witness and quickly elude the investigation.
  • The Faceless: As his name suggests, Space Mask's face is concealed by a silvery tinfoil mask (though for all we know, it could be his actual face).
  • Healing Hands: Uses these on Yamanaka and Mikawa, showing the strength to even revive the dead, after getting them into a car accident when they are initially searching for him.

A Choju created from the unborn child of a pregnant woman named Yoshiko when Yapool dispersed a fragment of his essence in a cursed gemstone and gave it to Yoshiko, causing her to become pregnant with and give birth to Mazarius.
  • Achilles' Heel: The only way to defeat Mazarius is to somehow lift Yoshiko from Yapool's curse, which will cause Mazarius to cease to exist.
  • Breath Weapon: Breathes a cloud of white smoke.
  • Fetus Terrible: Befitting of one of the most nightmarish episodes of the show, Mazarius is an unborn baby transformed by Yapool into a monster while still inside its pregnant mother, so she gives birth to a monster. Its roar is even the modified screaming of an infant.
  • Intangibility: The creature itself is permanently intangible as its life force is linked to that of Yoshiko.
  • Mystical Pregnancy: Created from a very horrific example even more disturbing than it sounds. Yapool uses a magic gemstone to place a curse on Yoshiko to make her pregnant with a Choju, thus turning her into the source of Mazarius' life force.

Played by: Mahito Tsujimura (voice), Yoko Tadokoro (Michiru's actress)
Alien invaders who originally came to Earth 13 thousand years ago, but were forced to slumber inside a giant pyramid after a great flood. However, they returned in the present, sending out their Choju Sphinx to destroy Tokyo and a female agent disguised as a girl named Michiru to interfere with TAC.

  • Sealed Evil in a Can: They had been slumbering for thirteen thousand years, waiting for the opportunity to return and take over Earth.

Sphinx

https://static.tvtropes.org/pmwiki/pub/images/sphinx_1_8.png

First Appearance: The Pyramid is the Choju's Nest
An ancient Choju lent by Yapool to the Orion aliens thousands of years ago. The creature was sealed in a pyramid in ancient times until returning in present-day Japan where the Choju was awoken to ravage civilization and commanded with a mystical whistle.
  • Beware My Stinger Tail: Sphinx has two snakes in place of tails that allow it to attack enemies when not facing them directly.

  • Playing with Fire: Shoots a stream of flames from the cobra on its headdress.

Alien Hipporito

https://static.tvtropes.org/pmwiki/pub/images/hippyrito.png

First Appearance: Total Annihilation! The Five Ultra Brothers!
Voiced by: Isao Yatsu
An evil alien unaffiliated with Yapool who came to Earth to defeat the Ultramen. He easily overwhelmed Ace, Zoffy, Ultraman, Ultraseven, and Ultraman Jack with his petrification powers, forcing the mighty Father of Ultra to make his grand debut in order to help TAC save the day.

Infamous as one of Ultraman Ace's most powerful enemies, Alien Hipporito has reappeared a few more times in the Ultra Series, complete with his deadly petrification abilities. However, the original Hipporito design above hasn't been used in decades in favour of a more menacing one dubbed Super Alien Hipporito.


  • Arc Villain: Takes center stage as main villain in episodes 26 and 27.
  • Blinded by the Light: Hipporito can create blinding flashes of light from his antennae.
  • Breakout Villain: Hipporito is notorious as being one of the most formidable opponents of any Ultra hero in the Ultra Series, making him a very popular choice whenever Tsuburaya Productions wants to recycle an older alien who will put up a major challenge for their heroes.
  • Breath Weapon: Breathes fire, as well as explosive smoke, from his trunk-like mouth. Some manga of the series have depicted him being able to spray a tar-like fluid as well — an ability never displayed in the show.
  • Chest Blaster: Can fire lasers from his chest.
  • Eye Beams: One of his minor abilities.
  • Hand Blast: Can launch heat-seeking missiles from his hands.
  • Interim Villain: One of the few villains unaffiliated with the Big Bad. Since Yapool is recovering, Hipporito causes trouble for couple episodes before he's dealt with, allowing Yapool to re-emerge.
  • Playing with Fire: Asides from the aforementioned Breath Weapon, Hipporito can also encase his fists in fire to improve his punches.
  • Shock and Awe: Shoots lightning from his antennae.
  • Taken for Granite: His most dreaded ability, the Hipporito Capsule. Hipporito can create a transparent canister around any victim he chooses. The canister then fills with a strange gas that turns its victims to jade. In later incarnations, the gas turns victims to bronze instead.
  • The Worf Effect: He defeats no less than five Ultramen in a row with his petrification powers. Naturally when the Ultra Father steps in to save the day, the evil alien gets his ass kicked hard.

Lunatyx

https://static.tvtropes.org/pmwiki/pub/images/lunaticks_data.png

First Appearance: Farewell Yuko, Sister of the Moon!
A rabbit-like Choju sent to ravage the world by consuming lava from the Earth's mantle to create tectonic instability. It is recognized by Minami though, and the reasons for why, as she will reveal to Hokuto, will change their relationship forever.

Arguably the fourth Choju in the Velokron-Vakishim-Doragory Power Trio, Lunatyx has reappeared many times in the Ultra Series due to the significance of its debut episode for Ultraman Ace.


  • Arch-Enemy: Of Yuko Minami, for destroying her ancestors' homeworld.
  • Breakout Villain: Although not as immensely popular as Vakishim, Velokron, and Doragory, Lunatyx has been appeared just as often as they have since their returns in Ultraman Mebius. Its weirdness certainly helps with its memorability.
  • Breath Weapon: Two actually. The first is a standard flame breath and the second is poisonous white gas.
  • Evil Is Not Well-Lit: As expected from a Moon monster, Lunatyx is nocturnal.
  • Eye Scream: An incredibly weird variation. Lunatyx's eyes can be fired straight from their sockets like missiles. Don't worry though, Lunatyx can regenerate them instantly to launch a rapid succession of them.
  • Hair-Raising Hare: Yup, Yapool will make anything into a Choju.
  • Kill It with Fire: Its death.
  • Magma Man: Drinks lava.
  • Moon Rabbit: Based on the Eastern legend, with the twist being that Lunatyx had actually destroyed the Moon's civilization long ago.
  • Overly Long Tongue: Which acts as a tube for sucking up magma.
  • Our Monsters Are Weird: A giant rabbit that eats lava and shoots its eyeballs like missiles?
  • Punny Name: Lunatyx is a Moon-themed rabbit Choju whose concept could only have been conceived by lunatics.

  • Tunnel King: As a monster that feeds on lava, Lunatyx is capable of burrowing about.

  • Achilles' Heel: his chest is his most vulnerable point.
  • Beneath the Earth: Ungramon hails from underground and seeks to conquer the surface world by enslaving humanity and blotting out the Sun.
  • Breath Weapon: Breathes a blue beam of restraining energy.
  • Chest Blaster: Can fire a blue energy beam from his chest.

  • Eye Beams: Able to shoot red lasers from his eyes.
  • Spell My Name with an "S": Sometimes called Undergroundmon.

Gitagitanga

https://static.tvtropes.org/pmwiki/pub/images/gitagitanga_i.png

First Appearance: The Sixth Ultra Brother
A subterranean Choju given to Ungramon by Yapool to allow the underground humanoid to destroy surface civilization. Gitagitanga was responsible for the death of Dan Umezu's father when it attacked the factory he was working at.
  • Expy: Gitagitanga's head was modeled after that of Giladorus from Ultraseven, being another tunneling monster.
  • Poisonous Person: The horns of Gitagitanga's head spray a poisonous white gas that intoxicates those who inhale it, allowing the monster to easily destroy its surroundings. They also have explosive properties.
  • Tunnel King: Being in the service of Ungramon makes Gitagitanga a proficient buurrower. Its Boss Subtitles is even "Subterranean Super-Beast".

Red Jack

https://static.tvtropes.org/pmwiki/pub/images/red_jack_0.jpg

First Appearance: The Ultra Star That Even You Can See
A dinosaur-like Choju that unexpectedly appears to attack Tokyo, killing a young girl's mother and sister and getting Hokuto into serious trouble for his irresponsibility leading to their deaths.
  • Breath Weapon: Breathes fire.
  • Everything's Better with Dinosaurs: Red Jack is definitely one of the more normal-looking Choju in the show, given its saurian appearance.
  • Hand Blast: Able to fire electrical beams of energy from its palms by putting them together.
  • Smoke Out: Red Jack's signature ability is to conjure a cloud of black smoke that allows it to vanish and reappear as it wills. The Choju's Boss Subtitles is even "Black Cloud Super-Beast".

Baktari

https://static.tvtropes.org/pmwiki/pub/images/baktari.png

First Appearance: From Seven to the Hand of Ace
A perfectly ordinary zoo tapir that was given the ability to transform into a Choju at will, thanks to Yapool's meddling. The result is that whenever TAC harms the Choju, the tapir sustains the injuries as well.
  • Hollywood Acid: Able to spray acid from the bulbous tube-like organ above its head.
  • Meaningful Name: Baktari's name is derived from "Baku", a creature from Japanese folklore said by many to resemble a tapir.
  • Playing with Fire: Can shoot fire from its claws.
  • Synchronization: Injuries that Baktari sustains as a Choju carry on in tapir form, notably a bandaged shoulder. This allows TAC to eventually track down the monster to the local zoo where they try to kill the tapir. Fortunately, Ultraseven arrives to help Ace restore the tapir to normal.
  • Voluntary Shapeshifting: Can switch between tapit and Choju form as it pleases.

Coakes

https://static.tvtropes.org/pmwiki/pub/images/coakes_0.jpg

First Appearance: With a Prayer Upon the Ultra Star
Portrayed by: Hitoshi Takahashi (human form)
A Choju that unexpectedly attacks a JSDF base and TAC, using its mind disruption abilities to get Hokuto framed. After escaping, it takes on the form of a boy named Akira Hoshino to befriend Dan Umezu and continue to harass Hokuto.
  • An Arm and a Leg: Ace defeats Coakes by ripping off both of its arms.
  • Brown Note: Coakes' signature ability is to emit a flash of sound that disrupts human brainwaves, confusing the enemy and disorienting their senses. It was this ability that it used to get Hokuto into trouble.
  • Creepy Child: Coakes' human form, Akira Hoshino.
  • Hand Blast: Able to shoot red laser bullets from its hands, although similar projectiles are fired from its forehead as well.
  • It Can Think: Unlike every other Choju so far, Coakes is indicated to be fully sentient, as it interacts with the human characters quite normally in its human form (unlike Vakishim's human form, who simply went on a vicious killing spree) and actually launches its attack on TAC by piloting a spaceship.

Bad Balloon

https://static.tvtropes.org/pmwiki/pub/images/bad_baalon_0.jpg

First Appearance: Shoot Down that Hot-Air Balloon!

  • Voluntary Shapeshifting: can transform into a perfectly normal hot-air balloon; well, normal until it eats whoever's riding it.

    • Finally, Kaiteigagan possesses a Breath Weapon consisting of hailstorm of purple energy bolts.
  • Sea Monster: An aquatic seashell-based Choju that Yapool sends out to destroy ships.

https://static.tvtropes.org/pmwiki/pub/images/dreamgillas.png

A Choju that terrorizes the nightmares of a boy named Yukio, formed from the stains caused by his bedwetting problems. Dreamgillas eventually begins to manifest in the real world from a lake when Yukio starts daydreaming.

  • Living Dream: Specifically formed from the kinds of nightmares that cause kids to pee in their beds.
  • Making a Splash: Due to being formed from wet stains on a bed, Dreamgillas not only relies on water to sustain its power, but is able to spray a high-pressure gush of water from its mouth.
  • Our Monsters Are Weird: Another contender for most deranged Choju in this series — Dreamgillas is a Living Dream formed from the bedwetting stains of a kid! And even then, just look at that thing!

https://static.tvtropes.org/pmwiki/pub/images/sound_gillar.jpg

First Appearance: This Choju is 10 000 Phones?

  • Our Monsters Are Weird: Yeah, at this point, you might be noticing that Yapool's monsters are getting a lot wackier. One reviewer described it as looking like "a giant toe with a satellite dish on its head".

Played by: Toshiya Sugita (voice), Chikichi Okamura (human form actor)

First Appearance: Ghost Story: The Lion Drum
A Choju formed from a cursed Lion Dance mask being used by the same man controlling Kaimanda. The mask was given to his son Shinda, transforming him into the Choju to help Kaimanda punish all of Japan.
  • Blinded by the Light: Shishigoran is able to flash its eyes to create explosive light that blinds enemies as well.
  • Breath Weapon: Breathes fire, just like Kaimanda.
  • Demonic Possession: Since Shishigoran is normally just a traditional Lion Dance mask, the Choju has to physically appear by taking over the body whoever wears it.
  • Evil Mask: Manifests from one, specifically base don those used in Lion Dances like this one.
  • Panthera Awesome: Modeled after lions, or more accurately the kinds featured in the traditional Lion Dance of many East Asian cultures.

First Appearance: Mystery! Resurrection of the Monster Woo!
An icy Choju that Yapool uses to try freeze all of Japan. It appears at Idatoge Valley while TAC and the Umezus were taking a winter vacation there, but soon has to face the wrath of not only Ultraman Ace, but the mythic Woo.

https://static.tvtropes.org/pmwiki/pub/images/onidevil.jpg

An Oni-based Choju that appears on the Setsubun holiday to attack TAC and Ultraman Ace after Hokuto and Kono eat red beans cursed by Yapool to vastly weaken their upper body strength.
  • Achilles' Heel: Destroying Oni-Devil's big red horn will vastly weaken the Choju and render it powerless.
  • Blinded by the Light: Can emit blinding flashes of light from its main horn.
  • Casting a Shadow: The same horn that creates the blinding flashes can create a cloud of darkness to cloak its surroundings.
  • Oni: The first of several monsters in the Ultra Series based on these infamous Japanese demons. Perhaps fittingly, it appears in an episode revolving around a holiday dedicated to dispelling evil spirits.
  • Spell My Name with an "S": Also called Onidevil.

Gasergon

https://static.tvtropes.org/pmwiki/pub/images/gasegon.jpg

First Appearance: Big Pinch! Save Ace!
An atomic Choju mutated from some sort of extraterrestrial monster. Gasergon's arrival from space gives TAC a serious challenge as its highly radioactive body making it into the equivalent of a walking nuclear bomb.
  • Action Bomb: The immense amount of radiation in Gasergon's body makes it similar to a living atomic bomb, so TAC and Ultraman Ace have to be extra careful in dealing with it.
  • Breath Weapon: Has two breath weapons; the first is a standard stream of fire, and the second is a deadly cloud of toxic gas.
  • Came from the Sky: Descends upon Earth by crashing into a satellite in the form of a black cloud before entering the atmosphere as a glowing red orb of fire.
  • I Love Nuclear Power: Gasergon's big theme. The Choju is highly radioactive and can produce thermal radiation from its body at will, which also means that killing Gasergon could cause the monster to go through a disastrous nuclear meltdown.
  • Spell My Name with an "S": Also called Gaseron and Gasegon.
  • Whip It Good: Gasergon's arms are a pair of powerful whips.

Daidarahoshi

https://static.tvtropes.org/pmwiki/pub/images/daidarahoshi_by_14doranc_d4pxufw.jpg

First Appearance: Ride Beyond the Time Machine
A bizarre Choju able to travel through time, using its ability to evade TAC through the space-time continuum and appear in both past and present in order to destroy a sacred statue.
  • Breath Weapon: Breathes fire.
  • Fighting Clown: The Choju's battle with Ultraman Ace is quite silly. Notably, the two engage in a mock swordfight by using trees to fence each other until Daidarahoshi fakes its death when being struck to the chest.
  • Meaningful Name: Named after the Daidarabotchi, a mountain giant in Japanese folklore.
  • Our Monsters Are Weird: Daidarahoshi definitely ranks among Yapool's more insane creations, with its gibbering cackle-like roar, ability to travel though time, and an appearance that was once described as looking like something straight out of a Dr. Seuss book.
  • Time Master: Daiadarahoshi possesses the ability to travel through time as it pleases, so TAC actually has to borrow a primitive time machine from some scientists in order to pursue the crazy-looking monster.

Hanzagiran

https://static.tvtropes.org/pmwiki/pub/images/hanzagiran.png

First Appearance: Curse of the Salamander
A Japanese giant salamander turned into a Choju empowered by the anger of an elderly man towards his village for their disrespect to the environment. The old man used a special flute to command his pet salamander to become a Choju as he willed.
  • Breath Weapon: Hanzagiran breathes a spray of acid that while ineffective against steel, is able to dissolve stone and flesh.
  • Meaningful Name: Hanzagiran's name is derived from "Hanzaki", a type of salamander youkai that has become the informal name of the Japanese giant salamander.
  • Pet Monstrosity: While its Choju origins make it clear Yapool had a hand in its creation, Hanzagiran is mainly loyal to the old man whose hatred and flute empower it; not to mention that he keeps its normal salamander form as his pet (though it's actually illegal in Japan to keep a Japanese giant salamander as a pet).
  • The Power of Hate: Yapool granted the old man's pet giant salamander the ability to become a Choju using his own hate towards his fellow villagers for polluting the local rivers.

Univargles

https://static.tvtropes.org/pmwiki/pub/images/univerlages.jpg

First Appearance: The Flying Jellyfish
A malefic jellyfish-like alien who enslave Aquarius and uses her to help him take over Earth by tricking some superstitious villagers into believing he and Aquarius were gods by blotting out the Sun and promising the bring it back.
  • Flying Seafood Special: The episode's name is Exactly What It Says on the Tin.
  • God Guise: His plan to take over the world was to assume this by blotting out the Sun and then telling people that only he had the divine power to save them. Of course, it also served to turn people against TAC and Ultraman Ace.
  • Spell My Name with an "S": This guy's Japanese name (Yunibaragesu) is quite hard to translate, so variations include Univerlages, Univergales, Univarges, and so on and so forth.
  • Starfish Aliens: One of the few alien races in the Ultra Series played by a marionette instead of a man in a suit.

Aquarius

https://static.tvtropes.org/pmwiki/pub/images/aquariuss.jpg

First Appearance: The Flying Jellyfish
Played by: Hirose Takako (human form actress)
An alien from the namesake constellation who was enslaved by Univargles to help him with managing a cult to worship the two of them and get said cultists to kill TAC for them.
  • Alas, Poor Villain: TAC feels pretty bad for Aquarius after Ace kills her. Ace even gives her a proper burial and pays his respects before leaving.
  • Bird People: Her true form is a bird-headed humanoid with a highly asymmetrical fashion sense.
  • Blinding Bangs: Over her right eye.
  • The Dragon: To Univargles, making her one of the few aliens in this series to be serving an alien other than Yapool. However, she's portrayed more sympathetically than her master.
  • God Guise: Like Univargles, Aquarius pretends to be a deity to deceive gullible villagers and turn them against TAC, though her ability to assume a human form lets her communicate directly to their cultists.
  • Meaningful Name: In her human form, Aquarius carries a communication device disguised as a water jug, in reference to the constellation she's named after.
  • Shoulder Cannon: The flower on her left shoulder can act as one, able to fire deadly bolts of explosive energy.

Alien Revole

https://static.tvtropes.org/pmwiki/pub/images/revole.png

First Appearance: Mass Chaos in Tokyo! Traffic Signals Gone Haywire!
Portrayed by: Eiichi Kikuchi (voice), Toya Takanobu (human form)
The alien who is given control of the Choju Signalion by Yapool, intending to use the monster to cause massive amounts of destruction in Tokyo by creating vehicle accidents with Signalion's traffic manipulation powers.
  • Hack the Traffic Lights: Revole's entire scheme was to do this by using Signalion. It actually works quite well, as he causes several fatal car crashes in thee episode and turns Tokyo into a driver's nightmare.

Signalion

https://static.tvtropes.org/pmwiki/pub/images/signalion.jpg

First Appearance: Mass Chaos in Tokyo! Traffic Signals Gone Haywire!
A Choju that possesses the ability to manipulate traffic lights, which Alien Revole uses to cause all sorts of chaos in the streets of Tokyo by having the Choju.
  • Blinded by the Light: Can flash brights lights in the colours of traffic signals from its head to blind enemies.
  • Extra Eyes: Has a third eye smack on the top of its forehead. Appropriately, whereas its two main eyes are green and orange, the third eye is red.
  • Eye Beams: Signalion can fire three of these from each of its eyes, with the beam's colours matching those of the eyes.
  • Hack the Traffic Lights: Signalion's signature ability is to make traffic signals go haywire in order to wreak massive havoc. Furthermore, Signalion can weaponize traffic lights
  • Our Monsters Are Weird: Seriously, just look at this guy!
  • Smoke Out: Signalion can emit three types of smoke from its body — a superheated red one, a yellow one that causes it to go berserk, and a blue one that allows it to vanish in thin air.

Geegon

https://static.tvtropes.org/pmwiki/pub/images/geegon.jpg

First Appearance: Life-Stealing Sound
A Choju formed from the violin of a boy named Haruo who refused to play it, to which Yapool took advantage of to create a monster able to suck the life out of anyone who hears its music.
  • Achilles' Heel: Destroying Geegon's strings renders it powerless.
  • Make Me Wanna Shout: Being an instrument-based monster, Geegon is able to emit a terrible high-pitched screech from its body to incapacitate foes.
  • Make My Monster Grow: Starts off the size of an average violin, but grows as it steals more lives with its music.
  • Musical Assassin: Geegon's signature gimmick is that in its violin form, it plays music that drains the life out of anyone who hears it, causing the violin to grow to kaiju-sized proportions.
  • Our Monsters Are Weird: Behold! One of the strangest monsters in the series, as well as the entire Ultra Series up to this point! Simply put, Geegon is a giant violin who can steal the life force of those who listen to it, eventually transforming into a half violin, half bird Choju who can fire beams from its pegs!
  • Shock and Awe: Shoots paralyzing lightning bolts from its pegs.
  • Voluntary Shapeshifting: Can assume the form of an animated violin that plays music by itself.

Jumbo King

https://static.tvtropes.org/pmwiki/pub/images/jumbo_king_render.png

First Appearance: Tomorrow's Ace is You!
A chimera Choju formed when Yapool (in the disguise of a friendly alien boy named Simon) merged the spirits of a few of the previous Choju in one final attempt to destroy Ultraman Ace.
  • Breath Weapon: Has two breath weapons — a stream of fire and a hail of laser bullets.
  • Eye Beams: Fires yellow laser beams from its eyes.
  • Hybrid Monster: The first one of the Ultra Series. Yapool specifically used the parts of Unitang, Mazaron-Man, Cowra, and Mazariusnote  and merged them together into a form approximate to that of Brocken.
  • The Juggernaut: As expected by what is supposed to be Yapool's ultimate Choju (at least until Ultraman Mebius introduced U-Killersaurus), Jumbo King is incredibly strong and highly resistant to the majority of Ultraman Ace's attacks.
  • Off with His Head!: How Ace defeats it.
  • Super Strength: Every bit as physically powerful as you would expect for a creature with the comined might of four Choju.
