History Characters / UltramanAce

!!Black Satan
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/black_satann.png]]

-->'''First Appearance''': Yapool, Demon of Revenge
A statue of a monster that was animated into a Choju by Yapool's latest alien agent, Space Mask. The sinister invader had commissioned a group of children he had befriended into actually constructing the statue without telling them of its true purpose, unleashing it on Tokyo when they least expected it.

!!Aprasar
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/aprasar_1.jpg]]

-->'''First Appearance''': I Saw the Phantom of a Heavenly Woman!
-->'''Played by:''' Junko Hitomi (human form actress)
A beautiful alien woman from the Virgo constellation who was mind controlled by Yapool after the extradimensional entity destroyed her homeworld. Yapool used her as an agent of his in order to sabotage TAC and then transformed her into a Choju to battle Ultraman Ace.

* BlowYouAway: Can conjure powerful winds by using her robes like the wings of flying kaiju.
* ClothingCombat: Aprasar uses her orange robes to great effect in combat, including lashing them out as a rope to grab enemies. Furthermore, the silks in her robes can entangle small objects that get caught in them.
* HumanAliens: Her true form, or how she looked before Yapool turned her into a Choju.
* {{Intangibility}}: Able to make herself ghostly so those who try to strike her will simply pass through her.
* LightEmUp: The crest of her head can fire a hailstorm of explosive bullets of light.
* MeaningfulName: Aprasar is named after the Apsaras, a race of beautiful female spirits in Indian mythology who were imported to Japan with the spread of Buddhism, becoming known as Ten'nyo. Her BossSubtitles is even "Ten'nyo Super-Beast".
* SpellMyNameWithAnS: Also called Aprasall.
* TragicVillain: Saved from her doomed homeworld by Yapool (who was the one responsible for its destruction in the first place) and then turned into one of his minions against TAC. [[spoiler:Luckily Ace manages to save her from Yapool's control and brings her to a new homeworld to live the rest of her life in peace.]]

!!Space Mask
[[quoteright:240: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. Space Mask is a silvery alien who came to Earth in the disguise of a kind-natured kindergarten teacher named Jiro Sakai, getting his students build a statue of a monster for him while he befriended TAC to spy on Hokuto and Minami.
----

-->'''Voiced by:''' Hirofumi Takada, Hitoshi Takahashi (human form)

!!Giron-Man
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/giron_man.png]]

-->'''First Appearance''': Giant Ant Choju vs. Ultra Brothers
-->'''Voiced by:''' Ritsuo Sawa
A subterranean alien recruited by Yapool to assist in conquering Earth. The alien relied upon Aribunta to dig out a complex systems of caverns and tunnels underneath Tokyo to attack people from below, hide from TAC's investgations, and trap Ultraman Ace when he came underground to pursue the invader.

* BeneathTheEarth: Giron-Man's species hail from underground, so he decides to turn the entirety of Tokyo's underground into his lair.
* BondVillainStupidity: After trapping Ultraman Ace in his lair, beneath a DescendingCeiling, Giron Man simply leaves Ace to his fate while going to the surface to join his pet monster Aribunta in destroying the city. This allows Ace to fire an Ultra Sign and summon Ultraman Zoffy, who is thankfully near Earth, to bail him out.
* DishingOutDirt: Was able to create massive stalactites and stalagmites from the ground in order to make a cage for Ace.
* {{Foreshadowing}}: At the beginning of the episode an eye looks out from the sky. This is not the eye of Yapool or Aribunta. In the third act, it's revealed the eye belongs to Giron-Man, revealing himself to an unsuspecting Ace.
* MasterOfIllusion: Giron-Man creates an illusion of Aribunta that Ace chases, battles, and quickly destroys, giving him the opportunity to create his prison around the hero.
* NearVillainVictory: Manages to trap Ace underground with no way out. If Zoffy wasn't in the area at the time he would've won.
* PowerPincers: Able to fire laser bullets from his pincers.
* PutTheirHeadsTogether: Zoffy and Ace [[spoiler:kill him and Aribunta with this method.]]
* ShockAndAwe: Was shown to be able to electrify the prison of stalactites and stalagmites he created to torture Ultraman Ace.
* TeleportSpam: Uses this ability to elude Ace when the hero pursues him through his cave network.

!!Brocken
[[quoteright:240: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 heading back to Earth and possess one of the astronauts aboard, Koyama. On Earth, the Brocken-controlled Koyama blended in with his family, intent on waiting for the perfect opportunity to strike at TAC.
----

!!Alien Metron Jr.
-->'''First Appearance''': Kaiju vs. Choju vs. Seijin
The son of the first [[Series/UltraSeven Alien Metron]], fully intent of avenging his father's death at the hands of the Ultras. 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 cataclysm.

See Characters/UltraSeven

* ArtEvolution: 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.
* AvengingTheVillain: He's the son of the original Alien Metron working with Yapool to avenge his father's death on Earth.
* BlindedByTheLight: Unlike other versions of Alien Metron (including his old man), Metron Jr. can create explosive flashes of blinding light from his hands.
* CultureClash:[[spoiler:How Metron Jr.'s cover is blown. The Metrons have no concept of wedding rings so when Yuko Minami asks Maya for it she gives it up like it's no big deal. This convinces Yamanaka that she's being controlled by an alien.]]
* DemonicPossession: The only incarnation of Metron to do this, which he does to infiltrate TAC's base.
* HalfTheManHeUsedToBe: [[spoiler:His fate.]]
* HandBlast: 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.
* KillAndReplace: Kills Maya and then takes her dead body as a disguise.
* TeleportSpam: Yet another ability not seen in other incarnations of Alien Metron (Alien Metron doesn't have a lot of unique powers, okay?).

!!Muruchi II
-->'''First Appearance''': Kaiju vs. Choju vs. Seijin
A species of kaiju previously encountered by [[Series/ReturnOfUltraman Ultraman Jack]] that suddenly appeared while Ultraman Ace was battling Doragory and Metron Jr and decided to help Ace's foes. While not referred to as such in its episode, this Muruchi is not the same individual as the first, but supplementary materials elaborated that he may in fact be directly related to his predecessor. Muruchi II angered Doragory when Ace dodged an attempted charge by the fish-like kaiju, and Doragory proceeded to rip Muruchi II apart, leaving the monster to die a painful death.

See Characters/ReturnOfUltraman

* AdaptationalVillainy: In its original appearance, Muruchi was a TragicMonster that was only rampaging to avenge the death of its benevolent master. Here, Muruchi II freely joins Metron Jr. and Doragory's fight with Ace with little provocation or motivation, seemingly for no other reason than the fact it wanted to fight Ace and saw the others as its allies.
* AnArmAndALeg: Had its leg and lower jaw ripped off by Doragory.
* CruelAndUnusualDeath / FamilyUnfriendlyDeath: Doragory dismembers Muruchi II very graphically on-screen and uncensored, tearing its jaw and leg clean off.
* DiabolusExNihilo: Muruchi II's appearance is as unexpected as it is unexplained, still baffling fans to this day.
** The ''Ultraman Encyclopedia'' aims to rectify this by stating it to have hatched from an egg laid by the original monster from ''Series/ReturnOfUltraman'', although this creates a plot hole of its own; the first Muruchi was aboard Mates's spaceship for the majority of the episode, so when did it lay the egg?
** Fans have speculated that the first Muruchi actually survived its fight with Jack and was then disturbed by Ace's battle with Doragory and Metron Jr. (even though the creature was clearly killed by a Specium Ray on-screen).
* {{Jawbreaker}}: After Doragory gets enraged, his first act is to mutilate Muruchi II by ripping off his jaw, taking off a massive amount of flesh from his neck and torso in the process. Neither this, nor [[AnArmAndALeg having his leg torn off]] kill him immediately, so it can be assumed he died slowly and in agonising pain.
* VillainTeamUp: With Metron and Doragory until Muruchi II rubbed Doragory [[FamilyUnfriendlyDeath the wrong way.]]
* WeHardlyKnewYe: Appears at the end of one episode and killed off barely minutes later in the following episode.
* TheWorfEffect: Muruchi II'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
[[quoteright:240: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 inside 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.

* BreathWeapon: Spits explosive darts.
* BulletCatch: Was able to catch the missiles fired by TAC from their planes, and actually hurl them back at the aircraft. Ace does the same with his mouth darts.
* DeadlyDisc: Gammas is able to create razor discs from its body and toss them at foes.
* DoubleWeapon: Yapool creates a two-headed spear for Gammas during its battle with Ultraman Ace.
* ImpaledWithExtremePrejudice: [[spoiler:Gammas' fate.]]
* {{Invisibility}}: One of its powers.
* {{Ninja}}: Its BossSubtitles are "Ninja Super-Beast", although other than having abilities that enhance its elusiveness, it doesn't have much in common with ninjas.
* OurMonstersAreWeird: Even by the standards of this show, Gammas is one freaky beast.
* PhantomZonePicture: Gammas' signature ability is to hide inside photographs, allowing it to completely conceal itself from TAC and make surprise attacks as it wishes.
* SmokeOut: Does this during his fight with Ace, disappearing briefly in a puff of smoke.

!!Alien Antira
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/achira_seijin_by_guigazone_d4qj74p.jpg]]

-->'''First Appearance''': Battle! Ace vs. [[Series/ReturnOfUltraman Hideki Goh]]!
-->'''Voiced by:''' Hirofumi Takada
Another alien agent in the service of Yapool. Antira took the form of [[Series/ReturnOfUltraman Hideki Goh]] in an effort to hinder Hokuto against Zaigon and get away with it through Goh's reputation, as well as deceive [[Series/ReturnOfUltraman Jiro Sakata]], who is ecstatic to see his older brother figure/friend return.

* BitchInSheepsClothing: When the episode introduces him we are initially led to believe that he's Goh returning home but really he's an evil alien disguise
* {{Shapeshifter}}: Another of those ''Franchise/UltraSeries'' 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.
* ASinisterClue: While disguised as Hideki Goh, he uses chopsticks with his left hand. The real Hideki is right-handed.
* SpellMyNameWithAnS: Also called Achira.

!!Zaigon
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/zaigon_0.jpg]]

-->'''First Appearance''': Battle! Ace vs. [[Series/ReturnOfUltraman 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 horned Choju to attack Tokyo while he dealt with Hokuto and Minami in his disguise as the human host of Ultraman Jack.

* BullSeeingRed: 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.
* InformedAbility: Both Yapool and Alien Antira say that he's invincible, [[spoiler:but he goes down pretty easily with a simple slash attack.]]
* OffWithHisHead: [[spoiler:How Ultraman Ace kills it.]]
* RedHerring: 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.
* RhinoRampage: Although he doesn't look the part, Zaigon is modeled after rhinoceroses (with some bull thrown in). Case in point, its BossSubtitles is "Rhino Super-Beast"

!!Unitang
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/unitang_2.jpg]]

-->'''First Appearance''': The Choju is Ten Women?
-->'''Played by''': Setsuko Minami (also human form actress)
A Choju that was sent by Yapool to destroy TAC's new Choju-detecting radar system. Unitang has the ability to transform into 10 young women -- an ability that it not only used to stay out of TAC's sight, but to get the better of Hokuto and prevent him from becoming Ultraman Ace.

* BreathWeapon: Breathes sticky webbing, though it also sprays the same stuff from its claws.
* HornAttack: Like Vakishim, Unitang can launch its horn like missile. It can also create explosions by flashing its horn. Also, the horn is the leader of the collective consciousness of the monster. [[OurMonstersAreWeird Did we mention this one is weird?]]
* IAmLegion: A weird example of this trope. Each of the 10 women makes up a body part for Unitang that combined into the titular monster.
* ImMelting: [[spoiler:Ultraman Ace defeats Unitang by dissolving it with acid.]]
* MindControl: In its 10 girls form, Unitang does this to Hokuto by placing a device on his neck.
* {{Multiboobage}}: Her choju form has '''eight''' breasts.
* OurMonstersAreWeird: 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.
* ProjectileWebbing: She has the ability to fire sticky threads from her mouth. Which can explode after ensnaring targets.
* PullingThemselvesTogether: Ultraman Ace finds this out when he chops Unitang to pieces.
* SpiderPeople: Her insectoid appearance, large fangs with the ability to shoot webbing and limbs resembling insect appendages gives her an arachnid-esque appearance. Some dubs (like the Cantonese version) even calls her the "Spider-Choju".
* VoluntaryShapeshifting: Can transform itself into 10 pretty, young, bike-riding women, who are able to do a FusionDance to turn back into their Choju form.

!!Sabotendar
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/sabotendar_render.png]]

-->'''First Appearance''': The Red Flower of Cactus Hell
A cactus Choju that managed to successfully injure Ultraman Ace in their first fight, using the opportunity to then hide from TAC by disguising itself as an ordinary-looking (albeit carnivorous) cactus that was then taken in by a boy who named it "Saburoten", unaware of its true nature. Sabotendar also made a brief appearance in ''Series/UltramanTaro'', although this remains the Choju's only reappearance to date.

* BreathWeapon: It has two -- a stream of fire and a spray of acid.
* CactusPerson: It's a giant, roughly humanoid cactus kaiju with the ability to turn into a regular succulent, SpikeShooter powers, and a prehensile tongue. It can also curl itself into a massive spiked ball to execute a spiked RollingAttack.
* HalfTheManHeUsedToBe: [[spoiler:Ace slices Sabotendar up when the monster rolls up into its ball form.]]
* MeaningfulName: Derived from "saboten", which is Japanese for "cactus".
* OverlyLongTongue: Which it uses to ensnare Ultraman Ace during their fight. Ace managed to [[TongueTrauma sever the tongue]] with his dual palm laser.
* RollingAttack: Sabotendar can curl itself into a spikey ball to fly and bash enemies.
* SpellMyNameWithAnS: Sabotendar or Sabotender?
* SpikeShooter: As is expected for a cactus-themed monster, Sabotendar can launch its thorns as explosive missiles.
* ToServeMan: Eats a couple of humans when it is disguised as a regular cactus.
* VoluntaryShapeshifting: It can transform itself into a small cactus. However, in this form, Sabotendar will consume living food it's given such as insects.

!!Barabas
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/barabass.png]]

-->'''First Appearance''': Execution! The Five Ultra Brothers!
A vicious and powerful Choju sent by Yapool to overwhelm TAC and distract Ultraman Ace while he engineered a plan to lure 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.

* BlindedByTheLight: Can create paralyzing flashes of light from the sword-horn on its head
* BreathWeapon: Breathes fire.
* EpicFlail: Its right hand.
* FamilyUnfriendlyDeath / CruelAndUnusualDeath: [[spoiler: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 scythe hand and using it to chop off its head!]]
* GrapplingHookGun: In its flail hand.
* HoistByHisOwnPetard: [[spoiler: His ultimate fate, where he gets impaled by his own sword and decapitated by his own scythe courtesy of Ace]].
* HookHand: Its right hand is a spiked ball tipped with a grappling hook, while its left hand is a scythe-like weapon.
* HornAttack: Barabas has a sword-shaped horn on its head that it can shoot like a missile or use as a blade.
* KickTheDog: When he first shows up he murders a child right in front of his little brother.
* MeaningfulName: Barabas is named after Barabbas, an insurrectionary mentioned in the Bible as having been freed by Pontius Pilate over Jesus Christ at his crucifixion. The name vaguely references this story with Ace being forced to go back to Earth to deal with him instead of saving his brothers from being crucified, only to abandon the fight and return for a second battle to finish him off after Ace Killer is taken down.
* OffWithHisHead: [[spoiler: What finally, finally, ''finally'' took him down]].
* PrehensileTail: Barabas has a three-pronged tail that it uses to strangle Ace in their battle.
* RasputinianDeath: [[spoiler: His over-the-top eventual demise, which is enough to kill a regular monster multiple times over; after a violent thrashing from Ace, he ends up getting impaled by his own sword, having his eyes ripped out his socket, and finally getting decapitated]].
* SpellMyNameWithAnS: 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.
* ThrowingYourSwordAlwaysWorks: Barabas attempted to use this against Ace by firing its sword horn at him, but it ended up being used against him [[spoiler:when Ace caught the blade and threw it back into its chest, beginning its RasputinianDeath.]]
* VisualPun: [[spoiler:Appropriately for a Choju appearing in an episode themed after the Passion of Christ, Barabas gets killed by Ace using its own sword and scythe against it. In other words, it [[https://en.wikipedia.org/wiki/Live_by_the_sword,_die_by_the_sword lived by the sword, and died by the sword]].]]

!!Ace Killer
[[quoteright:300: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 [[Series/{{Ultraman}} Ultraman, Zoffy]], Series/UltraSeven and [[Series/ReturnOfUltraman Ultraman Jack]] when Yapool successfully lured them to the planet Golgotha, where they were crucified and drained of their power.

An iconic opponent of Ultraman Ace, Ace Killer has reappeared many times in the ''Franchise/UltraSeries''. 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 [[Series/UltramanMebius Mebius Killer]] and [[Series/UltramanGinga Victory Killer.]]

* BreakoutVillain: 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.
* EvilKnockoff: Meant to resemble a demonic Ultraman, as it specifically exists to kills Ultra heroes.
* GlowingEyesOfDoom: Its only real facial features are its bright green eyes.
* TheJuggernaut: Since it was made specifically to kill Ultras, Ace Killer is highly resistant to all but the most powerful of Ultraman beam attacks
* NamesToRunAwayFromReallyFast: Never mess with a Choju with the last name ''Killer''.
* NounVerber: Victory, Mebius, Ace. You name the Ultra, Killer will be upgraded to defeat it.
* PowerCopying: 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.
* PowerParasite: Steals the powers of the first four Ultra Brothers by absorbing them through its "Colour Timer". In the case of Ultraman Jack, Ace Killer simply steals his Ultra Bracelet instead.
* RightHandOfDoom: The huge claws on the left hand.
* ShouldersOfDoom: He wears spiked pauldrons on both shoulders in all of his appearances.
* TheWorfEffect: 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.

!!Ace Robot
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/acerobot.png]]

-->'''First Appearance''': The Five Stars that Scattered Through the Galaxy
A robotic duplicate of Ultraman Ace, created solely to be a test subject for Ace Killer's stolen powers. Ace Robot is supposedly as strong as Ultraman Ace, and the machine's destruction demonstrates how much of a challenge the real Ace will go on to face against the cyborg.

* BlingOfWar: Like the earlier, Alien Salome-produced Robot Ultraseven in ''Series/{{Ultraseven}}'', this robot is equipped with numerous accessories to make it stand out from the real thing. Unlike Robot Ultraseven, Ace Robot's gear is gold in colour.
* NonMaliciousMonster: Unlike most of the other Imitation Ultras, Ace Robot wasn't built with the intention of damaging the reputation of its biological counterpart, rather being constructed as a mere test subject.
* MassOhCrap: Ace Robot's destruction induces this reaction from the Ultra Brothers, especially when combined with Yapool's [[EvilGloating boasts about Ace Killer's power]].
* RasputinianDeath: Is subject to each of the powers Ace Killer stole, with Zoffy's M87 Ray finally blowing it to pieces.

!!King Crab
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/king_crab.jpg]]

-->'''First Appearance''': Curse of the Black Crab
-->'''Voiced by''': Mahito Tsujimura
A crustacean-based Choju created by Yapool from a horseshoe crab with a vendetta against humankind. King Crab appeared out of the sea while Konno was taking a vacation to visit his niece, seeking vengeance against humanity while also assuming its original form to hide from TAC.

* ArchEnemy: A normal horseshoe crab that attempts to warn humanity of its corrupted relative’s impending attacks.
* AttackTheTail: When King Crab is on the receiving end of a NoHoldsBarredBeatdown by Ace, the monster tries retaliating by using its tail to strangle Ace. But Ace simply creates an energy ''drill'' with his hands and shreds King Crab's entire tail into bits.
* GiantEnemyCrab: Doesn't look much like one, but is based on crustaceans and horseshoe crabs (although the latter are actually more closely related to spiders).
* MakingASplash: King Crab can spray extremely slimy seawater that is capable of damaging power lines.
* PlayingWithFire: Can shoot a jet of flames from its forehead.
* ThePowerOfHate: Yapool created King Crab by using an ordinary horseshoe crab's hatred for humans.
* PrehensileTail: Possess a long and powerful tail lined with spines, using it to throttle Ultraman Ace.
* SeaMonster: Since it's based on crustaceans, King Crab first surfaces from the ocean to destroy an oil refinery.
* TailSlap: Thanks to its ridiculously long tail.
* VoluntaryShapeshifting: Can turns itself into a horseshoe crab.

!!Cowra
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/cowra_1.jpg]]

-->'''First Appearance''': Monster Story: Cow God Man
-->'''Played by''': Keizo Kanie
A Choju created by Yapool from a friend of Yoshimura named Takai, who had stolen a cattle nose ring sacred to the Cattle God. Using the legend of the Cattle God, Yapool cursed the nose ring to turn Takai into a half-bull hybrid and eventually a giant bovine monster.

* BullSeeingRed: Ultraman Ace plays a bit of "matador" with this guy during their fight.
* HornAttack: Other than the obvious goring attacks, Cowra can shoot a purple laser from between its horns.
* MasterOfIllusion: Can create hallucinations to confuse enemies.
* OurMinotaursAreDifferent: It's a cow Choju; what did you think?
* SuperSpit: Has acidic saliva.
* ToServeMan: Gorges himself on a few people during his rampage
* WasOnceAMan: 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
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/hotarunga_esu.jpg]]

-->'''First Appearance''': Ghost Story: The She-Devil of Firefly Field
A firefly Choju that was sent out by Yapool to destroy TAC's V7 Missile program after his initial to transform a paraplegic girl named Tamiko into a demon-like murderer called the She-Devil in exchange for letting Tamiko see her deceased mother was foiled by Minami.

* AcidAttack: Hotarunga can spray a highly acidic mist from its forehead. The mist also has explosive and suffocating properties for a good measure, but TAC blasts the monster's forehead to give Ace a much-needed upper hand.
* BewareMyStingerTail: Uses its tail to paralyze Ace during their fight and was about the finish Ace luckily [[BigDamnHeroes TAC had his back.]]
* BigCreepyCrawlies: Inspired by fireflies.
* BlindedByTheLight: Being a firefly-based monster, Hotarunga can emit stunning flashes of light from its body to incapacitate opponents.
* MeaningfulName: "Hotaru" means "firefly" in Japanese.

!!Black Pigeon
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/pigeon_i.jpg]]

-->'''First Appearance''': Lend Me the Pigeon
Once a boy's pet homing pigeon named Kojiro, 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 Kojiro's former owner tried to bring his pet back to its senses with some success.

* AlasPoorVillain: As an ordinary animal beloved by a child, [[spoiler:Black Pigeon's death actually saw little celebration as Kojiro remains dead after the Choju turns to normal upon defeat.]]
* AttackReflector: Black Pigeon is able to bounce beam attacks of its body by using its own chest.
* BlowYouAway: As with most flying monsters, Black Pigeon can create huge gales from the flaps of its wings.
* BreathWeapon: 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 [[https://en.wikipedia.org/wiki/Crop_milk pigeon milk]].
* GiantFlyer: As to be expected from a bird Choju.
* MusicSoothesTheSavageBeast: 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.
* PeskyPigeons: Being a pigeon monster, though somewhat more sympathetic due to the circumstances of its creation and defeat.
* SpikeShooter: Black Pigeon's got a single massive spike on its chest that can be fired like a missile.
* TragicMonster: One of the few Choju to be treated with pity due to its connection with its former human owner. [[spoiler:The fact that it doesn't get turned back into Kojiro to live the rest of its days as normal makes it even sadder.]]

!!King Kappa
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/king_kappa.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.

* AchillesHeel: Since it's a kappa monster, King Kappa needs to have water in its head at all times or else it will die.
* BreathWeapon: Breathes a white mist of unknown properties.
* CompositeCharacter: While based on kappas, its ability to eat kids' navels is taken from {{Raiju}}, who were known to eat the uncovered navels of children.
* HalfTheManHeUsedToBe: [[spoiler:After Ultraman Ace drains all the water from its head depression.]]
* HandBlast: Able to fire energy bullets from its fingertips.
* {{Kappa}}: Obviously.
* NoOntologicalInertia: After Ultraman Ace defeats King Kappa, everyone who lose their bellybuttons gets it back.
* OurMonstersAreWeird: We are dealing with a {{youkai}}-based monster that disguises itself as a swimming pool to kidnap kids, eat their bellybuttons, and turn them into kappas with the help of an android couple. Definitely one of Yapool's weirder schemes.
* RidiculouslyHumanRobots: It has two human-looking robot servants who attempt to get kids into the pool so they can be kidnapped.
* VoluntaryShapeshifting: King Kappa can disguise itself as a swimming pool, thanks to its water-filled depression.

!!Zemistar
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/zemistar_i.jpg]]

-->'''First Appearance''': The Star of Youth, the Star of a Couple
A cicada-based Choju that Yapool sent out to wreak havoc on ships arriving into Suruga Bay by levitating them into the sky.

* BigCreepyCrawlies: A cicada monster, which is largely evidenced by its BossSubtitles of "Giant Cicada Super-Beast".
* BladeBelowTheShoulder: Zemistar possesses a pair of mantis-like claws that it can use to slash at foes.
* BreathWeapon: Able to spit fire from its proboscis.
* GravityMaster: Yapool used Zemistar's ability to manipulate gravity in order to levitate ships helplessly into the air.

* BlowYouAway: Can conjure powerful winds by using her robes like the wings of flying kaiju.

-->'''First Appearance''': Yapool, Demon of Revenge
A statue of a monster that was animated into a Choju by Yapool's latest alien agent, Space Mask.

[[quoteright:240: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. Space Mask is a silvery alien who came to Earth in the disguise of a kind-natured kindergarten teacher named Jiro Sakai, getting his students build a statue of a monster for him while he befriended TAC to spy on Hokuto and Minami.

* BitchInSheepsClothing: 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.
* CameFromTheSky: 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.
* TheFaceless: 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).

!!Mazarius
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/mazarius_1.png]]

-->'''First Appearance''': Behold! A Great Transformation at Midnight!
A Choju created from the unborn child of a pregnant woman named Yoshiko when Yapool dispersed a fragment of his essence into a cursed gemstone and gave it to Yoshiko, transforming her unborn child into Mazarius and turning her into a creature named Yojo that acted as Mazarius' life source.

* AchillesHeel: The only way to defeat Mazarius is to destroy the cursed gemstone that created it, which will lift Yoshiko from Yapool's curse and cause Mazarius to cease to exist.
* BreathWeapon: Breathes a cloud of white smoke.
* FetusTerrible: 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 becomes the life source of a monster.
* HellIsThatNoise: Mazarius constantly makes ghastly wails similar to that of a human infant. Its cries grow more frantic after [=TAC=] try to fight it, in spite of the monster's intangibility.
* {{Intangibility}}: The creature itself is permanently intangible as its life force is linked to that of Yoshiko.
* MysticalPregnancy: Created from a very horrific example even more disturbing than it sounds. Yapool uses a magic gemstone to place a curse on Yoshiko that turned her unborn child into a giant monster and Yoshiko herself into Mazarius' life source.
* RetGone: [[spoiler: Mazarius is eventually erased from existance after Yapool's curse is broken]].

!!Mazaron-Man

-->'''First Appearance''': Behold! A Great Transformation at Midnight!
-->'''Voiced by:''' Rituso Sawa

* HandBlast: Can shoot beams from the tips of his fingers, as well as combined them to create an explosive punch.

-->'''First Appearance''': The Pyramid is the Choju's Nest
-->'''Played by''': Mahito Tsujimura (voice), Yoko Tadokoro (Michiru's actress)
Alien invaders who originally came to Earth thirteen 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.

* BizarreAlienBiology: The Orion aliens are only able to breathe a specialized toxic gas that contains extraterrestrial metals that are hazardous to humans. Thus, when they awake in the present to conquer Earth, they begin to fill the atmosphere with the gas to change it to their suiting.
* DeathEqualsRedemption: [[spoiler:Thanks to the kindness of Seiji and being betrayed by her people, the female spy, Michiru gives her life to save Ace by distracting Sphinx.]]
* PyramidPower: The Orion use a giant floating pyramid as their lair and their place of entombment.
* SealedEvilInACan: They had been slumbering for thirteen thousand years, waiting for the opportunity to return and take over Earth.

[[quoteright:240: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 alongside its masters until returning in present-day Japan where the Choju was awoken to ravage civilization and commanded with a mystical whistle used by the Orion agent Michiru.

* BewareMyStingerTail: Sphinx has two snakes in place of tails that allow it to attack enemies when not facing them directly.
* BlindedByTheLight: Sphinx's cobra headdress can create powerful flashes of agonizing light.
* {{Mummy}}: Keeping with the Egypt theme of the Choju, Sphinx is undead, with its design taking inspiration from the sarcophagi of pharaohs.
* MusicSoothesTheSavageBeast: The Sphnix can be pacified by a soothing musical tune played by the good Orion alien girl. It doesn't last, however, as the good Orion alien is quickly executed by her master for her betrayal.
* OffWithHisHead: Ultraman Ace lops of Sphinx's head in battle, but the creature simply continues to run about like a headless chicken due to its undead physiology.
* OurSphinxesAreDifferent: In this case, they're undead kaiju created by an EldritchAbomination long ago to help alien invaders conquer Earth.
* PlayingWithFire: Shoots a stream of flames from the cobra on its headdress.
* SealedEvilInACan: Was slumbering inside the same pyramid as Alien Orion.

!!Alien Hipporito
[[quoteright:300: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, Series/{{Ultraman}}, Series/UltraSeven, and [[Series/ReturnOfUltraman 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 ''Franchise/UltraSeries'', 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.

* ArcVillain: Takes center stage as main villain in episodes 26 and 27.
* BlindedByTheLight: Hipporito can create blinding flashes of light from his antennae.
* BreakoutVillain: 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 Creator/TsuburayaProductions wants to recycle an older alien who will put up a major challenge for their heroes.
* BreathWeapon: 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.
* ChestBlaster: Can fire lasers from his chest.
* EvilLaugh: Much of his dialogue consists of evil gloating to taunt TAC and the Ultras as he defeats them.
* EyeBeams: One of his minor abilities.
* HandBlast: Can launch heat-seeking missiles from his hands.
* InterimVillain: One of the few villains unaffiliated with Yapool. Since Yapool had been recovering from a major battle with Ace, Hipporito causes trouble for two episodes before he's dealt with, after which Yapool re-emerges to retake his role as the main antagonist.
* PlayingWithFire: Asides from the aforementioned BreathWeapon, Hipporito can also encase his fists in fire to improve his punches.
* RingOfFire: Thanks to his fiery powers, Hipporito eventually managed to trap the TAC in a burning circle. He's about to execute them, but gets interrupted by the Father of Ultra's timely arrival.
* ShockAndAwe: Shoots lightning from his antennae.
* SuperPersistentMissile: One of his missiles pursues a TAC jet for almost a minute, which TAC fpund out the hard way after spinning in circles and failing to lose the projectile. They need to jettison their ride and let their plane be destroyed.
* TakenForGranite: 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.
* TheWorfEffect: 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
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/lunaticks_data.png]]

-->'''First Appearance''': Farewell Yuko, Sister of the Moon!
A strange rabbit-like Choju sent to ravage Earth by consuming lava from the planet's mantle in order to create tectonic instability. However, it is recognized by Minami as a creature from her past, and the reasons for why, as she will reveal to Hokuto, will change the pair's relationship as Ace's dual hosts forever.

Although nowhere nears as recognizable as Vakishim, Velokron, or Doragory, Lunatyx is one of the most important Choju in the series due to the impact of its debut episode on the show's formula, and consequently, the monster has reappeared many times in the ''Franchise/UltraSeries''.

* ArchEnemy: [[spoiler:Of Yuko Minami, for destroying her ancestors' homeworld.]]
* BreakoutVillain: Although not as immensely popular as Vakishim, Velokron, and Doragory, Lunatyx has been appeared just as often as they have since their returns in ''Series/UltramanMebius''. Its weirdness certainly helps with its memorability.
* BreathWeapon: Two actually. The first is a standard flame breath and the second is poisonous white gas.
* EyeScream: 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.
* HairRaisingHare: Yup, Yapool will make anything into a Choju. Not that it detracts from it being an [[BewareTheSillyOnes effective threat]], though.
* KillItWithFire: [[spoiler:Its death.]]
* MagmaMan: Drinks lava.
* AMoltenDateWithDeath: [[spoiler: Ace kills the choju by dunking it headfirst into a pool of lava]].
* MoonRabbit: Based on the Eastern legend, with [[spoiler:the twist being that Lunatyx had actually destroyed the Moon's civilization long ago.]]
* OurMonstersAreWeird: A giant rabbit that eats lava and shoots its eyeballs like missiles?
* OverlyLongTongue: Which acts as a tube for sucking up magma.
* PunnyName: Lunatyx is a Moon-themed rabbit Choju whose concept could only have been conceived by ''lunatics''.
* SpellMyNameWithAnS: Lunaticks or Lunatyx? It seems to have settled on the latter name.
* TunnelKing: As a monster that feeds on lava, Lunatyx is capable of burrowing about.

!!Ungramon
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/undergroundmon_ii.png]]

-->'''First Appearance''': The Sixth Ultra Brother
-->'''Voiced by''': Osamu Saka
A subterranean humanoid who used the Choju Gitagitanga (lent by Yapool for assistance, naturally) to conquer the surface world by attacking major industrial regions and blotting out the Sun with its powers, as well as helping him fight Ultraman Ace and TAC.

* AchillesHeel: His chest is his most vulnerable point.
* BeneathTheEarth: Ungramon hails from underground and seeks to conquer the surface world by enslaving humanity and blotting out the Sun.
* BreathWeapon: Breathes a blue beam of restraining energy.
* ChestBlaster: Can fire a blue energy beam from his chest.
* {{Expy}}: Of Giron-Man from earlier, another pincer-handed subterranean humanoid who commands a Choju to attack humanity. The main difference is that Ungramon is a native of Earth whereas Giron-Man was an alien.
* EyeBeams: Able to shoot red lasers from his eyes.
* SpellMyNameWithAnS: Sometimes called Undergroundmon.
* WouldHurtAChild: Tries to hurl a child off a cliff after his cover is blown.

!!Gitagitanga

-->'''First Appearance''': The Sixth Ultra Brother
A subterranean, burrowing Choju given to Ungramon by Yapool to allow the strange underground humanoid creature 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 ''Series/UltraSeven'', being another tunneling monster.
* MadeOfExplodium: While DefeatEqualsExplosion applies to 99% of monsters throughout the franchise, Gitagitanga took it to the extreme by exploding after being ''thrown atop a building''. It's one of the few monsters who blows up despite ''not'' being hit by beam-related or missile attacks.
* PoisonousPerson: 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.
* TunnelKing: Being in the service of Ungramon makes Gitagitanga a proficient burrower. Its BossSubtitles is even "Subterranean Super-Beast".

!!Red Jack
[[quoteright:240: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 appeared to attack Tokyo, using its ability to appear at will in a smoke cloud. During its rampage, it killed a young girl's mother and sister, getting Hokuto into trouble for his irresponsibility leading to their deaths.

* HandBlast: Able to fire electrical beams of energy from its palms by putting them together.
* SmokeOut: 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 BossSubtitles is even "Black Cloud Super-Beast".

!!Baktari
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/baktari.png]]

-->'''First Appearance''': From [[Series/UltraSeven 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 not only is it difficult for TAC to track the Choju as it appears and disappears, but whenever they harm the Choju, the tapir sustains injuries as well.

* AcidAttack: Able to spray acid from the bulbous tube-like organ above its head.
* MeaningfulName: Baktari's name is derived from "{{Baku}}", a creature from Japanese folklore said to resemble a tapir.
* PlayingWithFire: 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. [[spoiler:Fortunately, Ultraseven arrives to help Ace restore the tapir to normal.]]
* VoluntaryShapeshifting: Can switch between tapir and Choju form as it pleases.

!!Coakes
[[quoteright:240: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 attacked TAC by piloting a spaceship, using its mind disruption abilities to get Hokuto framed for the damage. After escaping, it took on the form of a boy named Akira Hoshino to befriend Dan Umezu and continue to harass Hokuto.

* AnArmAndALeg: [[spoiler:Ace defeats Coakes by ripping off both of its arms.]]
* BrownNote: 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.
* CreepyChild: Coakes' human form, Akira Hoshino.
* HandBlast: Able to shoot red laser bullets from its hands, although similar projectiles are fired from its forehead as well.
* ItCanThink: 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. Its BossSubtitles "Humanoid Super-Beast" further support this.

!!Bad Balloon
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/bad_baalon_0.jpg]]

-->'''First Appearance''': Shoot Down that Hot-Air Balloon!
An incredibly weird balloon-based Choju that is able to disguise itself as a man-eating hot-air balloon. Using this innocuous form, Bad Balloon consumed any children that took a ride inside of it, literally draining them of their ability to have fun in the process.

* BalloonOfDoom: It's a man-eating balloon-like Choju whose main power is to disguise itself as a normal hot-air balloon.
* BewareTheSillyOnes: It's a weird balloon-based monster that looks like a fat elephant cyclops. It also has one of the more horrifying powers among Choju, preying exclusively on [[WouldHurtAChild children's emotions]] and draining their lively joy until they're almost catatonic.
* BreathWeapon: Can fire some kind of white mist from its trunk.
* {{Cyclops}}: Has only a single red eye.
* EmotionEater: Bad Balloon feeds on children's sense of fun, leaving them as joyless zombies. Disturbingly, the parents of its victims found this to be an ''improvement'' over their usual rowdy selves and set up campaigns rallying for the balloon to come to their neighbourhoods.
* HalfTheManHeUsedToBe: [[spoiler:Sliced in half with Ace's Ultra Guillotine, releasing hundreds of normal balloons and all the consumed children when it falls apart.]]
* LivingGasbag: A sentient hot-air balloon that is alive and can transform into a monster.
* MonsterClown: In keeping with the balloon motif, its true form has elements of this, being a brightly-coloured, rotund creature with horns resembling a jester cap.
* NoOntologicalInertia: [[spoiler:The children who lose their emotions to Bad Balloon gains them back after Ace defeats the monster]].
* OffWithHisHead: [[spoiler:Ace slices its head off, before bisecting it vertically.]]
* OurMonstersAreWeird: This show is full of crazy kaiju, but Bad Balloon is a good contender for being among the craziest. It's a ''man-eating hot-air balloon'', for crying out loud!
* SpellMyNameWithAnS: Also called Bad Baron and Bad Baalon.
* VoluntaryShapeshifting: Can transform into a perfectly normal hot-air balloon; well, normal until it eats whoever's riding it.

!!Kaiteigagan
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/kaiteigagan.png]]

-->'''First Appearance''': A Choju Dances on an Open Rainbow
An aquatic Choju created from seashells that suddenly appeared to wreck ships off the Japanese coastlines.

* BreathWeapon: Kaiteigagan has no less than three such abilities!
** Its first Breath Weapon is a simple spray of some kind of misty white gas, which we can presume is poisonous.
** Breath Weapon #2 is a large multicoloured ray of energy that stuns opponents it hits.
** Finally, Kaiteigagan possesses a Breath Weapon consisting of hailstorm of purple energy bolts.
* HomeFieldAdvantage: Inverted - it's a water-based choju, but somehow chose to take the fight onto dry land, where Ace doesn't suffer any penalties of fighting underwater and quickly tears Kaiteigagan a new hole. Incidentally, another water-based choju in the following episode (see below) would play this trope straight.
* SeaMonster: An aquatic seashell-based Choju that Yapool sends out to destroy ships.

!!Dreamgillas
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/dreamgillas.png]]

-->'''First Appearance''': A Gift from Zoffy
A bizarre Choju that terrorized the nightmares of a boy named Yukio, forming from the stains caused by his bedwetting problems. Thanks to these dreams, Dreamgillas eventually began to manifest in the real world from a lake when Yukio starts daydreaming.

* AchillesHeel: Dreamgillas needs a source of water to sustain itself, such as a lake, so simply draining the water will render the monster powerless.
* BreathWeapon: Dreamgillas is able to spew a nasty red liquid with explosive properties.
* EarFins: To complete the monster's seahorse-inspired appearance, Dreamgillas has fins in place of ears.
* EmbarrassingDampSheets: It's a nightmare that comes into being when Yukio wets the bed, complete with the stains being in the shape of the Choju itself. Yeah, this show is weird, okay?
* GigglingVillain: As if it isn't bizarre enough, Dreamgillas' roar is a series of childish giggling.
* HomeFieldAdvantage: Being a water-based choju fought near a lake, Dreamgillas utilizes the environment to it's advantage by dragging Ultraman Ace underwater, with the fight turning towards the choju's favor until Zoffy drops the Ultra-Array to give Ace some much-needed assistance.
* LivingDream: Specifically formed from the kinds of nightmares that cause kids to pee in their beds.
* MakingASplash: 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.
* OurMonstersAreWeird: Another contender for most deranged Choju in this series -- Dreamgillas is a LivingDream formed from the bedwetting stains of a kid! And even then, just ''look'' at that thing!

!!Soundgillar
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/sound_gillar.jpg]]

-->'''First Appearance''': This Choju has 10 000 Phones?
An incredibly bizarre-looking Choju that manipulates sound and feeds on the massive soundwaves created by loud noises. Soundgillar manifests wherever there is sound, requiring TAC to call upon the participation of all of Tokyo in order to overcome the Choju's sound-based abilities.

* HandBlast: Soundgillar can fire a variety of energy attacks from its hands, including a blast of shockwaves from its palms and organic missiles from its tube-shaped fingertips.
* MakeMeWannaShout: Soundgillar's specialty. Not only does it sustain itself through loud noises, but it is able to spontaneously manifest wherever sound is occurring, fire sonic shockwaves from its hands, and even create a binding ring of energy from its forehead that mutes enemies.
* OurMonstersAreWeird: 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".
* SpellMyNameWithAnS: Soundgillar or Soundgillas?

!!Machless
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/machless_0.png]]

-->'''First Appearance''': The Star of Friendship Forever
A reptilian Choju that attacks anything going faster than the speed of sound due to its intense hatred of loud noises. In particular, Machless targets extremely fast vehicles such as Japan's famous bullet trains and a racecar driven by an old friend of Hokuto.

* BreathWeapon: Breathes an explosive white gas.
* HandBlast: Can shoot electrical lasers from its claws.
* PunnyName: Machless attacks anything that goes at the speed of sound or above; in other words, it wants to have eliminate ''mach'' speed -- created a Mach-less world!
* SensoryOverload: It has very sensitive hearing, and for this reason, it hates loud noises and will attack anything it finds too loud.
* SpellMyNameWithAnS: Machless? Machles? Machres?
* TunnelKing: Mainly gets about by burrowing.

!!Snowgiran
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/snowgiran.png]]

-->'''First Appearance''': Resurrection! The Ultra Father!
A snowman-like Choju that Yapool lends to Namahage to terrorize Japan on Christmas Eve and punish the country for its adoration of a western tradition. More importantly, the icy monster's appearance marked the return of the Father of Ultra after his brief incapacitation at the hands of Alien Hipporito.

* BlindedByTheLight: Can emit blinding flashes of light from its forehead. Compared to other monsters that can do this however he straight-up severely damages the eyes.
* BreathWeapon: Breathes freezing mist from its trunk.
* EyeScream: Has the power to permanently destroy the eyeballs of people with a flash of light. Luckily [[DeusExMachina the Father of Ultras brings Yuko, who somehow has the ability to heal eyesight now.]]
* AnIcePerson: As its name suggests, Snowgiran is able to manipulate ice and cold temperatures, such as creating a blizzard at will.
* VoluntaryShapeshifting: Snowgiran is able to disguise itself as a human-sized snowman in order to surprise passerbys and attacks them.

!!Namahage
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/namahage.png]]

-->'''Voiced by''': Ritsuo Sawa
A {{youkai}} who is given control of Snowgiran by Yapool on Christmas Eve. Namahage used the Choju in order to punish Japan for their adoration of the western holiday of Christmas, which the youkai perceived as a sign of Japan abandoning its native traditions.

* TheGrinch: Namahage hates Christmas because he sees its foreignness as an offense to Japanese culture.
* UsefulNotes/MisplacedNationalism: He hates Christmas because he sees it as the ultimate embodiment of western values corrupting Japan.
* {{Youkai}}: Namahage is a notorious boogeyman from northern Honshu folklore who shows up on New Year's Eve in search of naughty children and ne'er-do-wells to punish.

!!Alien Fire
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/alien_fire.png]]

-->'''First Appearance''': The Life of Seven! The Life of Ace!
-->'''Portrayed by''': Goro Kataoka (human form actor)
An alien invader given control over the Choju Firemons by Yapool. He disguised himself as Dan Umezu's late uncle in order to get close to him and Hokuto while he got Firemons to battle Ultraman Ace and prevent the construction of a new TAC weapon called the Silver Shark.

* EyeScream: That little nareow slit in his face appears to be where his eyes would be located. [[spoiler: It's also the same spot Ace would stab through with Firemons' own sword at the conclusion of their fight]].
* FlamingSword: [[spoiler:After Firemons is destroyed,]] Fire takes Firemons' flaming sword to battle Ultraman Ace in the episode's final showdown.
* PlayingWithFire: As his name suggests, although he really doesn't display any fire powers. His BossSubtitles is "Fire Man" though.

-->'''First Appearance''': The Life of Seven! The Life of Ace!
A Choju given to Alien Fire by Yapool in order to sabotage TAC's latest weapons project. Firemons wields a deadly flaming sword that it uses to great skill, successfully killing Ultraman Ace with it in the hero's first battle against the monster!

* BreathWeapon: Breathes fire. Additionally, it shoots laser bullets from its nostrils.
* FlamingSword: Firemons' weapon of choice is a sword wreathed in fire that was not only able to burn Ace with even a light slash, but also ''kill him'' when the Choju stabbed him through the chest with it.
* GlassCannon: [[spoiler:Despite its swordsmanship skills and successfully killing Ace, Firemons is ultimately brought down by human weaponry.]]
* HeroKiller: [[spoiler:Don't worry, Seven brings Ace back to life.]]
* MythologyGag: Much like Zetton from ''Series/{{Ultraman}}'', Firemons appears in the 39th episode of his show, kills the main Ultra, and was defeated by human weaponry at the end.
* PlayingWithFire: Mostly in the name, as Firemons really doesn't have any other fiery powers except for fire-breathing and its sword of flame.
* PunnyName: Firemons is a fire monster...

!!Alien Steal
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/steel.png]]

-->'''First Appearance''': Give Back the Panda!
-->'''Played by''': Toshiya Sugita (voice), Chikichi Okamura (human form actor)
An extraterrestrial thief who came to Earth to steal panda-themed toys and merchandise, as well as the beloved panda of a local zoo, in order to turn pandas into his homeworld's next big cash cow craze.

* DastardlyWhiplash: His human disguise is this, complete with bowler hat, cape and cartoonish scheme.
* OutsideContextProblem: With the sole exception of Alien Hipporito, he's the only opponent in the series who has absolutely nothing to do with Yapool's schemes, with his plan being considerably less grand and much more self-serving.
* PlayingWithFire: Can shoot jets of flame from his antennae.
* PunnyName: An alien thief named Steal who looks like he's made of ''steel''
* ShockAndAwe: Able to fire red bolts of lightning from his antennae.
* StickyFingers: Steal's quite the kleptomaniac, and makes full use of his powers to allow him to steal as much merchandise as he can get his hands on. He'd probably have gotten away with it if Ace didn't intervene.
* SuperSpeed: Steal can run at speeds of 60 kilometers per hour in both his human disguise and his true form.
* WeaponizedTeleportation: Steal used this ability in order to rob stores and gather everything he's taken into one area.
* WouldHurtAChild: After being denied of having a living panda for himself, he turns himself into kaiju form intending to crush two kids, but thankfully Ace arrived just in time to beat him off.

!!Kaimanda
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/kaimanda_i.jpg]]

-->'''First Appearance''': Ghost Story: The Lion Drum
A Choju that manifested from a statuette of an evil god being used by a man who wanted to punish modern day Japan for not respecting the ancient tradition of the Lion Dance.

* AchillesHeel: The flaming wheel on Kaimanda's back is the source of the monster's pyrokinetic abilities. Destroying it will render Kaimanda powerless.
* BreathWeapon: Breathes fire.
* GodOfEvil: Said to be the manifestation of one, as it is formed from said deity's statue. Its BossSubtitles is even "Evil God Super-Beast".
* MultipleTailedBeast: Has two tails.
* PlayingWithFire: Kaimanda is stated to have numerous fire-based powers, although the only one we see is its fiery breath weapon.
* TailSlap: Kaimanda's twin tails allow it to bash its enemies quite effectively.

!!Shishigoran
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/shishigoran_1.jpg]]

-->'''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 Shinta, transforming him into the Choju to help Kaimanda punish all of Japan.

* BlindedByTheLight: Shishigoran is able to flash its eyes to create explosive light that blinds enemies as well.
* BreathWeapon: Breathes fire, just like Kaimanda.
* DemonicPossession: Since Shishigoran is normally just a traditional Lion Dance mask, the Choju has to physically appear by taking over the body whoever wears it.
* EvilMask: Manifests from one, specifically base don those used in Lion Dances like [[https://commons.wikimedia.org/wiki/File:Hasedera_monzenmachi_Sakurai_Nara_pref_Japan06bs.jpg this one]].
* PantheraAwesome: Modeled after lions, or more accurately the kinds featured in the traditional Lion Dance of many East Asian cultures.

!!Iceron
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/iceron.png]]

-->'''First Appearance''': Mystery! Resurrection of the Monster Woo!
An icy Choju that Yapool used to try freeze all of Japan. It appeared at a ski resort in Idatoge Valley while TAC and the Umezus were taking a winter vacation there, but soon had to face the wrath of not only Ultraman Ace, but the legendary guardian spirit Woo.

* AnArmAndALeg: Ultraman Ace rips off one of Iceron's arms before finishing him off.
* BreathWeapon: Breathes freezing mist.
* BuriedAlive: [[spoiler:Ultraman Ace defeats Iceron by entombing the Choju in a gargantuan avalanche created with his Metallium Ray.]]
* ExtraEyes: Has three red eyes.
* AnIcePerson: As its name suggests, Iceron's a Choju with winter-based powers, notably the ability to create a massive blizzard around itself.

!!Woo II
-->'''First Appearance''': Mystery! Resurrection of the Monster Woo!
A snow spirit first encountered by the original Series/{{Ultraman}} and born of the ghost of a deceased human parent. This second Woo was the ghost of a child's late father, who sought to protect his offspring from Iceron and assist Ultraman Ace in defeating the Choju.

See Characters/UltramanTVSeries

* ArtEvolution: Compared to the previous Woo seen in the original ''Series/{{Ultraman}}'', this one is more of a grayish colour.
* GenderFlip: The original Woo manifested from the spirit of a mother, but this Woo appears from the ghost of a ''father'' instead.
* PapaWolf: Whereas the first Woo was a MamaBear.

!!Fubigilara
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/fubigirara_0.jpg]]

--->'''First Appearance''': Ghost Story: Cry of the Yeti
A yeti-like Choju created by Yapool from an alien monster hailing from an icy planet. It makes itself at home in the Shiozawa skiing region, attacking resorts and villages while TAC and the Umezus are still vacationing in the area after their battle with Iceron.

* BigfootSasquatchAndYeti: As the episode's name suggests, Fubigilara is a Yeti-based Choju.
* BreathWeapon: Breathes a freezing mist, successfully freezing Ultraman Ace with it for a brief moment. Fubigilara really didn't count on Ace being able to thaw himself out.
* EyeBeams: Able to fire a thin red laser from both of its eyes.
* HalfTheManHeUsedToBe: [[spoiler:Its fate.]]
* AnIcePerson: Thrives in extremely cold regions due to having originated from an ice planet. Its BossSubtitles is even "Blizzard Super-Beast".
* SpellMyNameWithAnS: Also called Fubigirara, Fubugirara, and Fubugilara.

!!Oni-Devil
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/onidevil.jpg]]

-->'''First Appearance''': Setsubun Ghost Story: The Shining Bean
An {{Oni}}-inspired Choju that appeared on [[UsefulNotes/JapaneseHolidays the Setsubun holiday]] to attack TAC and Ultraman Ace after Hokuto and Konno had eaten red beans that were cursed by Yapool to make their arms go numb and thus unable to help battle the monster.

* AchillesHeel: Destroying Oni-Devil's big red horn will vastly weaken the Choju and render it powerless.
* AimForTheHorn: Ace managed to weaken Oni-Devil by kicking its middle horn off.
* BlindedByTheLight: Can emit blinding flashes of light from its main horn.
* CastingAShadow: 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 ''Franchise/UltraSeries'' based on these infamous Japanese demons. Perhaps fittingly, it appears in an episode revolving around a holiday dedicated to dispelling evil spirits.
* SpellMyNameWithAnS: Also called Onidevil.

!!Gasergon
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/gasegon.jpg]]

-->'''First Appearance''': Big Pinch! Save Ace!
An atomic-powered Choju mutated from some sort of extraterrestrial monster. Gasergon's arrival from space gave TAC and Ultraman Ace a serious challenge because its highly radioactive body made it into the equivalent of a walking nuclear bomb that would be devastating if killed improperly.

* ActionBomb: 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.
* AtomicSuperpower: 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.
* BreathWeapon: Has two breath weapons; the first is a standard stream of fire, and the second is a deadly cloud of toxic gas.
* CameFromTheSky: 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.
* SpellMyNameWithAnS: Also called Gaseron, Gasgegon, and Gasegon.

!!Daidarahoshi
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/daidarahoshi_by_14doranc_d4pxufw.jpg]]

-->'''First Appearance''': Ride Beyond the Time Machine
A bizarre-looking Choju able to travel through time and space whenever it wills itself to. Daidarahoshi used this ability to evade TAC through the space-time continuum and appear in both past and present as part of a plot by Yapool to destroy a sacred statue.

* BreathWeapon: Breathes fire.
* FightingClown: 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.
* MeaningfulName: Named after the Daidarabotchi, a mountain giant in Japanese folklore.
* OurMonstersAreWeird: 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.
* PlayingPossum: Pretends to be taken down for good by Ace, only to sneak back up when Ace tries getting near for a closer look.
* TimeMaster: 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
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/hanzagiran.png]]

-->'''First Appearance''': Curse of the Salamander
A [[https://en.wikipedia.org/wiki/Japanese_giant_salamander Japanese giant salamander]] that was turned into a Choju by Yapool using the anger an elderly man held towards his village for their disrespect to the environment. The old man used a special flute to command the salamander (which he kept as a pet) to become a Choju as he willed.

* BreathWeapon: Hanzagiran breathes a spray of acid that while ineffective against steel, is able to dissolve stone and flesh.
* HumansAreTheRealMonsters: Hanzagiran is the sole surviving Japanese giant salamander from the village's nearby river when all the other animals in the river were killed by pollution. The old man wants revenge for all the wildlife that were killed by the village's callousness.
* MeaningfulName: Hanzagiran's name is derived from "Hanzaki", a type of salamander {{youkai}} that has become the informal name of the Japanese giant salamander.
* PetMonstrosity: 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).
* ThePowerOfHate: 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
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/univerlages.jpg]]

-->'''First Appearance''': The Flying Jellyfish
A malefic jellyfish-like alien from the Aquarius constellation who sought to conquer Earth with the help of Yapool's Choju Aquarius. His scheme was to make the people of Earth worship him, tricking some superstitious villagers into believing that he was a god by blotting out the Sun.

* FlyingSeafoodSpecial: The episode's name is ExactlyWhatItSaysOnTheTin.
* GodGuise: 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.
* SpellMyNameWithAnS: This guy's Japanese name (Yunibaragesu) is quite hard to translate, so variations include Univerlages, Univergales, Univarges, and so on and so forth.
* StarfishAliens: One of the few alien races in the ''Franchise/UltraSeries'' played by a marionette instead of a man in a suit.

!!Aquarius
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/aquariuss.jpg]]

-->'''First Appearance''': The Flying Jellyfish
-->'''Played by:''' Hirose Takako (human form actress)
A humanoid bird Choju created from an alien native to the namesake constellation. Yapool lent Aquarius to Univargles, with the mutated alien helping the jellyfish-like creature manage and enforce his cult in the form of a priestess and get the cultists to kill TAC for them.

* AlasPoorVillain: [[spoiler:TAC feels pretty bad for Aquarius after Ace kills her. Ace even gives her a proper burial and pays his respects before leaving.]]
* BirdPeople: Her true form is a bird-headed humanoid with a highly asymmetrical fashion sense.
* HighPriestess: Her human form, as a priestess ruling over a village.
* MeaningfulName: In her human form, Aquarius carries a communication device disguised as a water jug, in reference to the constellation she's named after.
* NeckSnap: She's killed when Ultraman Ace lands an empowered high kick into her cranium, breaking her neck in the process.
* ShoulderCannon: The flower on her left shoulder can act as one, able to fire deadly bolts of explosive energy.

!!Alien Revole
[[quoteright:160: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)
An alien invader who was given control of the Choju Signalion by Yapool. Revole's evil schemes revolved around using Signalion to cause massive amounts of destruction in Tokyo by creating vehicle accidents with the monster's traffic light manipulation powers.

* DefiantToTheEnd: The last Revole warns TAC that he's not finished with the humans yet, even after his death, before he succumbs. Turns out he's right, with all the Revoles dead their monster Signalion is now free to wreak havoc the following day.
* HackTheTrafficLights: Revole's entire scheme was to do this by using Signalion. It actually works quite well, as he causes several fatal car crashes in the episode and turns Tokyo into a driver's nightmare.

!!Signalion
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/signalion.jpg]]

-->'''First Appearance''': Mass Chaos in Tokyo! Traffic Signals Gone Haywire!
A very unusual Choju that possesses the ability to manipulate traffic lights and make them go haywire. Revole used this creature's powers in order to cause all sorts of chaos in the streets of Tokyo by having the Choju mess around with the city's traffic.

* BlindedByTheLight: Can flash brights lights in the colours of traffic signals from its head to blind enemies.
* ExtraEyes: 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.
* EyeBeams: Signalion can fire three of these from each of its eyes, with the beam's colours matching those of the eyes.
* HackTheTrafficLights: Signalion's signature ability is to make traffic signals go haywire in order to wreak massive havoc. Furthermore, Signalion can ''weaponize'' traffic lights
* OurMonstersAreWeird: Seriously, just ''look'' at this guy!
* SmokeOut: Signalion can emit three types of smoke from its body -- a superheated red one, a yellow one that causes it to go berserk, and [[UsefulNotes/GreenIsBlue a blue one]] that allows it to vanish in thin air.

!!Geegon
[[quoteright:240: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, despite his mother's demands he take violin lessons. Yapool took advantage of this situation in order to create a monster that was able to suck the life out of anyone who hears its music.

* AchillesHeel: Destroying Geegon's strings renders it powerless.
* MakeMeWannaShout: Being an instrument-based monster, Geegon is able to emit a terrible high-pitched screech from its body to incapacitate foes.
* MakeMyMonsterGrow: Starts off the size of an average violin, but grows as it steals more lives with its music.
* MusicalAssassin: 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.
* OurMonstersAreWeird: 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!
* ShockAndAwe: Shoots paralyzing lightning bolts from its pegs.
* VoluntaryShapeshifting: Can assume the form of an animated violin that plays music by itself.

!!Jumbo King
[[quoteright:240: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 that had been defeated by Ultraman Ace into the most powerful Choju so far in one final attempt to destroy the hero once and for all.

* BreathWeapon: Has two breath weapons -- a stream of fire and a hail of laser bullets.
* EyeBeams: Fires yellow laser beams from its eyes.
* FinalBoss: While not the final Choju ever (other Choju would appear in subsequent series, such as Oil Drinker in ''Series/UltramanTaro'' and the below-mentioned U-Killersaurus in ''Series/UltramanMebius''), Jumbo King is Ace's final opponent in his series.
* HybridMonster: The first one of the ''Franchise/UltraSeries''. Yapool specifically used the parts of Unitang, Mazaron-Man, Cowra, and Mazarius and merged them together into a form approximate to that of Brocken.
* TheJuggernaut: As expected by what is supposed to be Yapool's ultimate Choju (at least until ''Series/UltramanMebius'' introduced U-Killersaurus), Jumbo King is incredibly strong and highly resistant to the majority of Ultraman Ace's attacks.
* OffWithHisHead: [[spoiler:How Ace defeats it.]]
* SeriesContinuityError: Cowra and Mazarius are two of the Choju composing Jumbo King's body despite the fact neither of them technically ever died [[spoiler:(they were only reverted back into their original forms)]].
* SuperStrength: Every bit as physically powerful as you would expect for a creature with the combined might of four Choju.

An extraterrestrial thief who came to Earth to steal panda-themed toys and merchandise, as well as the beloved panda of a local zoo, in order to turn pandas into his homeworld's next big cash cow craze ([[WidgetSeries this show can get pretty wacky, okay?]]).

* BodyHorror: Applies to humans possessed by Brocken. An arm and a mouth will grow on each hand, for starters.

* GlowingEyesOfDoom: Not in it's choju form, but on Brocken's human host. Seconds before his transformation, Koyama's eyes glows bright orange.
