History Characters / ReturnOfUltraman

* {{Planimal}}: One created via science gone too far, much like its SpiritualSuccessor, Biollante. To push the point further, Biollante's designer confirmed drawing cues from Leogon in designing her, with some concept art more closely resembling the Ultra kaiju. It even appears at Lake Ashi, just like Biollante does in her first fight with Godzilla!

A peaceful alien that came to Earth to build an alliance with humanity. Befriending a boy named Yoh, Earth pollution harmed Mates' body and powers, forcing him to take human form and losing his ability to detect the location of his hidden spaceship. Unfortunately, he was killed by an angry mob when they learned he was an alien, resulting in Mates' monster guardian Muruchi appearing to ravage the surrounding village.

* CreepyGood: Despite his rather eerie appearance (black pupilless eyes and pale white skin), Mates was essentially a benevolent alien.

* HumansAreTheRealMonsters: Beaten to death by a gang of angry townsfolk trying to defend his adopted son and being an alien. Additionally, the episode makes a point of how destructive humanity is to the environment by having the Alien Mates slowly poison from the pollution we created.
* InterspeciesAdoption: Mates adopted Yoh, a human, as his son while disguised. This would become an important plot point in ''Ultraman Mebius'' when Beo learns about from a schoolteacher who met Yoh as a little girl that the boy had inherited is late adopted father's belief in the possibility of friendly relations between Earth and his people.

* TooGoodForThisSinfulEarth: And how! The first truly good alien in the franchise is killed by a mob of humans. It's revealed in ''Series/UltramanMebius'' that his adopted human son Yoh also died young, though many years after Mates and long enough for him to pass Mates' beliefs in tolerance.

A fish-like monster that Alien Mates had been storing in his spaceship as an emergency weapon in case negotiations for an alliance with humanity turned ugly. Unfortunately, things did turn ugly when a prejudiced and fearful mob killed the alien, causing Muruchi to burst out of the alien's spacecraft and rampage about.

Due to his debut episode being among the most well-regarded in the franchise, Muruchi has made many more appearances in the ''Franchise/UltraSeries''. However, most of Muruchi's appearances since ''Series/UltramanMebius'' have renamed the monster Zoa Muruchi. This version of Muruchi is, for all intents and purposes, the exact same.

* EarFins: Has two small fins in place of ears. The ear fins are more distinct in it's future appearances as Zoa-Muruchi in Series/UltramanMebius and beyond.

* RoaringRampageOfRevenge: In its original appearance as well as ''Ultraman Mebius'', where it went on a rampage to punish humans for their racism and prejudice harming Alien Mates.

* WoobieDestroyerOfWorlds: Muruchi was not destroying its surroundings in its original appearance because of it was commanded to like most kaiju controlled by aliens, but instead to punish humanity for their hatred leading to Alien Mates' death. Goh even considers not transforming into Jack and letting the villagers reap their sins.

Although Leogon has never made any appearances since its debut, it is very notable for being essentially a prototype to the Creator/{{Toho}} kaiju [[Film/GodzillaVsBiollante Biollante]], for both kaiju were created by the same scriptwriter, Shinichiro Kobayashi, who submitted Leogon's story for a contest by Creator/TsuburayaProductions when he was 16 and would later submit a similar story to Toho Studios for the ''Franchise/{{Godzilla}}'' series.

* {{Planimal}}: One created via science gone too far, much like its SpiritualSuccessor, Biollante. To push the point further, Biollante's designer confirmed drawing cues from Leogon in designing her, with some concept art more closely resembling the Ultra kaiju.

[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/king_maimai_larva_extra.png]]
[[caption-width-right:240:Larval Stage]]

A prehistoric insect-reptile monster that had been slumbering for millions of years until miners disturbed it. While King Maimai itself wasn't especially dangerous, it had an extreme flatulence problem that was behind a series of disruptive earthquakes occurring around its mountain tomb.

* AllWebbedUp: Managed to entangle Jack in his webbing spray by sneaking behind the Ultra.
* AnArmAndALeg: In his larval form, Maimai lose an arm thanks to a dropped MAT grenade.
* AttackTheTail: Not as graphic as other examples in the franchise, and unlike other Ultras, Jack didn't sever King Maimai's tail completely. But he ''did'' snap the monster's tail with his knees, with a very audible ''crunch''.

* CurbStompBattle: The battle between Ultraman Jack and King Maimai goes completely in the Ultra's favour, with Jack effortlessly ripping its wings, severing its tail, and pummeling King Maimai so badly that it needs to resort to playing possum in order to turn the battle around.
* FakingTheDead: During his fight with Ultraman Jack he pretended to die. When Jack attempted to fly away Maimai attacked.
* {{Fartillery}}: King Maimai's farts are highly explosive.

* {{Gasshole}}: King Maimai's farts are so powerful they cause earthquakes!

* MixAndMatchCritters: Sorta looks like [[BigCreepyCrawlies a big cicada]] mixed with [[EverythingsBetterWithDinosaurs a dinosaur]].

* PrehistoricMonster: King Maimai was slumbering underground for millions of years before being awoken by miners. However, he's more goofy than menacing, given that his appearance is supposed to be a BreatherEpisode.

An alien who disguised himself as a mute and deaf boy visiting the MAT base with Captain Ibuki's daughter. He tormented Goh with telepathic taunts and threats that goaded the hero into lashing out against the disguised alien in order to discredit him, all while using his monster Plooma as a RedHerring for MAT. Alien Zelan also makes small cameos in other Franchise/UltraSeries from time to time.

* BitchInSheepsClothing: Since only Hideki Goh is able to hear Zelan's taunts and warnings, the other MAT members just see Goh bullying a little kid, which gets him briefly expelled from MAT. Only Captain Ibuki is willing to listen to Goh's accusations of the kid being an evil alien, but even he is reluctant as he doesn't want to get judgmental.
* CreepyChild: In the form of the little boy. Some of the shots they use to show of him communicating with Goh certainly make him even creepier.
* EyeBeams: He doesn't have true eyes, but he is able to fire a disintegration ray from the ridges on his face.

* KickTheDog: Kills the nurse looking after him once she finds him messing with the machine he uses to control Plooma.
* ManipulativeBastard: Spends the episode tormenting Goh and even enticing him to attack the alien in the disguise of a child.

Alien Zelan's monster of choice. The sinister invader sent out Plooma to attack Tokyo in order to distract MAT while Zelan himself concentrated on tormenting and eventually assassinating Goh completely unnoticed.

* TheJuggernaut: Able to survive the Specium Ray without taking much damage.
* OffWithHisHead: [[spoiler:Its fate.]]
* PetMonstrosity: Of Alien Zelan, who used the monster to destroy the city and distract MAT while he isolated Goh from the team to assassinate him.
* RedHerring: Plooma's purpose was to distract MAT from the real villain of the episode -- the disguised Alien Zelan. Its BossSubtitles is even "Decoy Monster".

A hermit crab monster that turned a crashed MAT space station called Space Station #5 into a makeshift shell, which proved to be a problem when Jiro decided to check out the station, disturbing the monster and putting the boy's life in danger as MAT tried to find a way to draw the creature out of its "shell".

* ImpaledWithExtremePrejudice: [[spoiler:Its fate when Jack turns the Ultra Bracelet into a lance. And then it catches on fire for a good measure.]]

* NonMaliciousMonster: Yadokarin's sole crime was making its shell out of a broken space station that Jiro happened to be wandering about inside, but MAT attacks it anyways.

An ancient beast that guarded an underwater cave full of the bones of prehistoric bison located at the bottom of a lake. However, paleontologists took bones from its lair, enraging it into coming out to rampage and attacking anyone that came close to its underwater home.

* AnimalMotifs: Oxter's primary motif is bison, although it really doesn't look anything like one.

* BrutishBulls: An ancient, rampaging kaiju based on bisons.

* HornAttack: They act as pincers too.
* OurMonstersAreWeird: A two-legged prehistoric bison who can spit acid from his mouth, has a chameleon-like tongue, and can only breathe in water.
* OverlyLongTongue: Which can be used as a whip capable of slamming a building down.
* NonMaliciousMonster: Oxter was content to dwell in its cave as long as the graveyard of the bison is undisturbed. [[spoiler:Ultraman Jack continues Oxter's duty by sealing off the cave and placing the kaiju's skeleton within.]]
* PrehistoricMonster: Oxter's the guardian of a cave full of bison fossils, so it's probably of Ice Age origin.

* StrippedToTheBone: [[spoiler:Its fate.]]

A bizarre jellyfish-like monster from the seas around Micronesia that is able to control weather in order to create massive typhoons. The creature came to Japan, travelling to the country alongside the enormous storms it created and battering every settlement in its path with them.

* BlowYouAway: Can spin its dome rapidly to levitate and create a tornado in the process.

* {{Cephalothorax}}: The suit actor's head is hidden in the dome.
* CombatTentacles: Its arms and tail.

* TheJuggernaut: Was totally unfazed by the Specium Ray, [[spoiler:so Jack simply defeated it by bringing it into space where it froze to death in the lack of atmosphere.]]
* MakingASplash: Varricane's presence is near-constantly surrounded by torrential downpour.
* OurMonstersAreWeird: Being a giant jellyfish that can control the weather is one thing, but every other little things about it makes it all the more bizarre.

* ShockAndAwe / ElectricJellyfish: Can deliver powerful electric shocks by grabbing enemies and create lightning storms.
* WeatherManipulation: Can conjure rainstorms and hurricanes much like Seamons and Seagorath before it.

An extraterrestrial beetle able to fire deadly laser beams from its singular antenna. Nokogirin initially arrived on Earth from a meteorite at the size of a typical insect and murdered several people. MAT subsequently went after it, but they inadvertently caused the monster to turn kaiju-sized!

* AchillesHeel: Nokogirin's lone antenna is its sole attack, so destroying it massively weakens the monster.

* DeathRay: Can shoot them from its single antenna.
* EyeScream: Thanks to MAT, allowing Jack to cut off it antenna.
* FourLeggedInsect: [[AvertedTrope Averted]] when Nokogirin’s bug-sized, but played straight as soon as he starts growing, as he loses two of his legs for no explained reason.

* MakeMyMonsterGrow: MAT's firepower somehow causes Nokogirin's size to increase from that of a standard bug to that of a Kaiju in the span of a few hours.

* ToughBeetles: An extraterrestrial stag beetle that can fire deadly laser beams and casually brush off Ultraman Jack's attacks in its Kaiju form.

An extraterrestrial monster that had been stranded on Earth. Zagoras spent its time creating a magnetic meteor-like transport to escape the planet by tearing up its surroundings to build up the vessel's size, consequently attracting the attention of MAT as its actions endangered humans.

* DeathByIrony: [[spoiler:Jack picks him up and slams him into the very meteorite he tried to leave Earth in.]]

* MagnetismManipulation: Zagoras' meteor-vessel magnetizes loose objects in its vicinity to add to its mass, so the monster smashes structures and tears up the earth in order to get large chunks of material for the meteor-thing.
* NonMaliciousMonster: Zagoras only wanted to leave Earth, and that was it. Unfortunately, its method of doing so was too dangerous for humanity, so MAT and Ultraman Jack have to kill it.

A crab-like monster from a planet in the Cancer constellation that fled to Earth in a state of madness when its homeworld was devoured by Vacuumon. Unaware of Vacuumon's slow arrival to Earth, MAT mistook Zanika for a threat and decided to destroy the terrified and maddened creature.

* AnArmAndALeg: Jack tears off Zanika's claws during the fight, forcing the monster to beg for mercy. [[spoiler:Mercy is granted, and after Zanika's homeworld is restored by Jack defeating Vacuumon, the pincers grow back.]]
* GiantEnemyCrab: From the constellation of Cancer fittingly enough.

A terrible nebula-like entity that consumes planets and other celestial bodies. The utterly colossal Vaccuumon made a slow path towards Earth that was merely hinted at for humanity by the vanishing of entire constellations in the sky and the arrival of a fleeing Zanika.

* EldritchAbomination: A titanic nebulous blob-like entity that consumes planets.

-->'''First Appearance:''' Horror! Birth of the Mansion Monster!
A peaceful little space creature that MAT took from some children and killed on the spot upon discovery as Earth had encountered far too many alien menaces to trust any extraterrestrial monsters. When one saddened boy took a piece of Kupukupu home, it attached itself to his bedroom's wall and transformed itself into the ferocious giant Kingstron.

* AdaptiveAbility: Killing Kupukupu allows the monster to mutate by merging any inanimate matter that its remains come in contact with, eventually regenerating into a completely new monster.
* ArtInitiatesLife: The surviving piece of Kupukupu slowly evolves into Kingstron by appearing as a drawing on a kid's bedroom wall that develops Kingstron's features and also gets bigger and more lifelike.

* TheJuggernaut: Kingstron was not fazed by the Specium Ray.
* HumansAreTheRealMonsters: Kupukupu was a totally defenseless and innocent monster blown up solely for being from space. MAT paid dearly when it resulted in the 60-meter-long Kingstron trashing Tokyo.
* MetamorphosisMonster: Kupukupu is a small, white, featureless quadruped, but after merging with the walls of a house, it transforms into Kingstron, a horned tortoise-like kaiju with spikes on its shoulderblades.

* StrippedToTheBone: [[spoiler:Kingstron's fate.]]

* WoobieDestroyerOfWorlds: A perfectly harmless monster turned into a not-so-harmless one by human mistrust and prejudice.

A bizarre extraterrestrial monster that broadcasts whatever it sees to televisions. It made a living out of disrupting air traffic by attacking planes and causing them to explode or collide midair, while remaining hidden from MAT through its disruption of radar signals.

A monster that lives in a garbage dump, hiding underneath the mountainous heaps of trash, driving away any humans who came into the place. Despite its appearance, it is impressively agile, and that proved to be a major annoyance for MAT and their frequent usage of missiles.

SelectiveMagnetism: Magnedon is also able to magnetize targeted objects, as it does with Ultraman Jack in the episode's fight.

* MeaningfulName: Jack is a popular name for heroes in English fairy tales, hence why the producers selected it as the characters name.

* SeeTheInvisible: While he can turn invisible, he can’t hide his shadow. Additionally, hitting Sartan will cause him to become visible again.

A docile extraterrestrial monster whose natural presence creates intense magnetic waves. Due to the amount of social disruption its power brought to humanity, MAT was forced to kill the peaceful creature, but Magnedon's slew of powers made this a lot harder than it seemed.

* FromASingleCell: Magnedon can regenerate from being blown to pieces within the course of a few hours.

* MagnetismManipulation: Its body constantly emits magnetic waves, capable of pulling a jumbo jet straight out of the sky.

* SelectiveMagnetism: Magnedon is also able to magnetize targeted objects, as it does with Ultraman Jack in the episode's fight.

A prehistoric bird-like monster that inhabited a volcanic island in the South Pacific. It caused a lot of trouble for MAT, Ultraman Jack, and the JSDF when it began to seek a place to build its nest, which results in Tokyo receiving the brunt of the attack.

* BreathWeapon: A spray of webbing that it normally uses to create its roost, though they're perfectly useful in entangling Ultramen as well. And in a slight variant, Terochilus can fire energy bullets from its nose.

* PrehistoricMonster: An ''Archaeopteryx''-based kaiju that resembles a pterodactyl.
* PteroSoarer: A kid even misidentifies it as Film/{{Rodan}}! However, Terochilus is actually based on ''Archaeopteryx'', but you have to remember that kaiju are never supposed to be realistic.

An electricity-eating turtle-like monster able to turn invisible. MAT's attempts to destroy it were hampered by a boy named Susumu who believed it did not deserve to be killed, despite the fact that the monster was responsible for the death of his father.

* EnergyAbsorption: It needs to consume elctricity in order to maintain its electrical powers. The invisibility is a separate asset.

* {{Invisibility}}: Eledortoise's main ability. Unlike Neronga, it can turn invisible at will instead of needing to consume electricity to power it.

* StockholmSyndrome: Despite the fact the monster killed his father, Susumu has a weird affection to it, seeing it as his monster to command despite the monster probably not even knowing he exists. He even mourns it when it’s finally killed.

A poisonous monster that had been consuming copious amounts of mustard gas canisters that had been illegally dumped in the wilderness by the Japanese Imperial Army during the Second World War, making the monster's toxic powers even deadlier!

* BreathWeapon: Breathes a toxic gas that has similar properties to mustard gas. However, it doesn't have much of an effect on Ultraman Jack.

* DoesThisRemindYouOfAnything: The kaiju was pretty much created by the screenwriters as a commentary on Japanese usage of chemical weapons in the Second World War, with the usage of mustard gas been treated very seriously here.

* HumansAreTheRealMonsters: While the monster isn’t shown sympathetically like most examples, the episode clearly shows that it only became as dangerous as it was because of human creation of the poisonous gas and the illegal dumping afterward by the Imperial Japanese government of World War II.

* SpikesOfDoom: Well, more like floppy quills of doom, but they're still loaded with enough deadly poison to give Ultraman Jack some trouble.

A monster that dwells in the Shirakami Mountains, but suddenly started rampaging shortly after a noisy highway started development in the area. It has mysterious connections to a landscape artist and his family who in the past spent a great deal of time vacationing in the region.

* AssholeVictim: The first victim of his rampage? A couple of perverts messing with the artist's daughter.

* OurGhostsAreDifferent: It's implied that Shugaron is in fact the vengeful spirit of an artist who liked to come to the region to paint its beautiful scenery, coming back as a monster to punish humanity for disturbing the landscape.
* TragicMonster: In some ways, Shugaron's rampage is justified, as the episode goes to great lengths to emphasize the SceneryPorn of its home that is being taken down for a busy highway. Made even more tragic by how it kills the artist's daughter in its rampage.

The female of a mated pair of sea monsters that devastate Japan and overwhelm Ultraman Jack using their ability to control the weather and the seas after being disturbed by ships passing over their home. She was the first of the two to battle Jack and MAT, calling forth her mate Seagorath when things got too intense for her.

* BattleCouple: With Seagorath. She proves to be easily overwhelmed by MAT firepower alone, but when she calls in her mate, the tables are turned.

* SeaMonster: A rhinoceros-like monster that spent its time attacking ships.

* WhatHappenedToTheMouse: [[spoiler:Seagorath dies of his injuries shortly after Ultraman Jack blows off his horn, hence being revived by Alien Nackle, but Seamons' fate is left unanswered, with her last appearance being fleeing with her mate back to the sea.]]

The second of two sea monsters that attack Tokyo using their ability to control the weather and the seas, appearing to assist his mate Seamons when MAT's firepower began to overwhelm her. Seagorath would later be brought back by Alien Nackle (via StockFootage) to battle Ultraman Jack again and allow the wicked invader to study Jack's weaknesses.

* AimForTheHorn: The MAT managed to blast off Seagorath's nasal horn in their second battle.

* SeaMonster: A dragon-like monster that spent its time attacking ships.

A monster with chameleon-like powers that inhabited the Japanese mountains, living its life in obscurity. Gorbagos was spotted by Jiro when he accidentally caught it on camera, but the hard part for MAT was figuring out a way to counter its camouflage.

* NonMaliciousMonster: Gorbagos was just sorta minding its own business, but MAT attacked it anyways when Jiro's camera spotted it.

An Earthtron-like monster that got an extremely powerful MAT weapon called the X-Bomb Missile stuck on its tail in a botched solo attempt by Goh to kill it.

* BewareTheSillyOnes: Despite Dangar's goofy appearance and behaviors (it has dreadlocks and moves by dancing!), it's still by no means a friendly monster.
* DreadlockRasta: Whatever the hell those things on Dangar head are they resemble dreadlocks

An undead sauropod-like kaiju awoken by a construction site. Unhappy about having its eternal rest disturbed, Stegon goes on a rampage, but while MAT is finding ways to destroy the monster, Jiro and his friends instead take pity on the creature.

* DemBones: The animated skeleton of an already dead prehistoric kaiju.
* EverythingsBetterWithDinosaurs: Undead dinosaurs!

* KarmaHoudini: [[spoiler:Stegon's punishment for killing people, smashing buildings, and causing general destruction? Nothing! And, why? Because a bunch of kids begged Ultraman Jack to spare it!]]
* NinjaZombiePirateRobot: It's an acid-spitting zombie brontosaurus, what more could you want?

* {{Stellification}}: In the end, Jack [[spoiler:turns it into a constellation because several children pleaded for Jack to hold back from killing it]].

* MissFanservice: In one episode, due to her wearing a miniskirt.

The final extraterrestrial of the series to try their hand at taking over Earth. Alien Bat's plan was to resurrect the infamous Zetton and use its dread reputation amongst the inhabitants of the Land of Light to intimidate Ultraman Jack into surrendering without a fight.

** Ultraseven saving Jack, who's about to be incinerated by the sun. After giving Jack a pep talk, Ultraseven then gives Jack a new backup weapon in case the situation gets too difficult to handle - the Ultra Bracelet, which becomes Jack's iconic weapon ever since.

The former's appearance in episode 38, "When the Ultra Star Shines" is a notably important moment in the franchise's history - it disproves the public's notions at the time that Ultraman Jack is the original Ultraman by a different name, establishing that Ultraman and Ultraman Jack are, ''in fact'', two separate individuals. As the series goes on, with more and more different Ultramen introduced with each series, it can be pretty much said that the establoished distinction between Ultraman and Ultraman Jack serves as a stepping stone in allowing the franchise to grow and grow.
