Nics (ニクス Nikusu) is a Reionics that first appeared in a stage show, Ultra Family Grand Assembly 2018. It was created alongside Ultraman Geed from Belial's genes by Kei, thus making Nics a sort of 'brother' to Geed, alongside Geed's other brothers.

The quartet are shown one of Honey Zelion's early results in the form of a stuff and framed honey bee enlarged to the size of a bird.
Amagi and Furuhashi duplicates
After being captured by Alien Iyros, UG agents Amagi and Shigeru Furuhashi were imprisoned in a frozen state onboard the invader's spacecraft. Using advance technology, Iyros cloned his prisoners in order to steal much-needed spaceship fuel from Ultra Guard home-base.
Despite fooling the other team members, Dan Moroboshi could tell that the duo were impostors from their subtly inhuman eyes. Shortly thereafter, Dan shoots the two duplicates during the robbery attempt, revealing their artificial origins to Captain Kaoru Kiriyama as their bodies disintegrate into a black liquid.
- The shoddy duplicates are directly spoofed in episode 15 of Patlabor: The New Files, "The Woman Who Came from the Stars", itself a dense parody of the original Ultraman and Ultraseven television series.
Sludge Master, or Venom Monster, is a jellyfish-like monster from the Return of Ultraman Voice Drama "Tokyo Crisis Hair That Came Back". According to the description given in it, Sludge Master is a small heavy weight monster that weighs 50,000 tons. It is also able to spew a corrosive brown acid

The unnamed robot clown was an agent of The Invaders and the direct servant of the disguised doll monster Kinder. Remaining mute and only communicating through facial expressions and body language, the robot clown was first employed to break into Dr. Hasunuma's home to retrieve the plans for his invention, Catcher A-1: a detection device and energy shield that could halt alien aggressors of all types. While unsuccessful in finding said documents, the robot clown manage to murder all the security guards stationed at Hasunuma's home with its unhuman strength as well as injuring Etsuko, Dr. Hasunuma's daughter, upon its escape.
Later that same day, the clown comes across Ichiro, son of Dr. Mitarai Kenichi, head of the SGM, by some vacant train tracks and gives the boy the Kinder doll. Unaware of the danger, Ichiro allows Kinder into his home where the monstrous spy locates the Catcher A-1 documents, takes photos with it doll eyes, and violently incapacitates Dr. Mitarai and his eldest daughter Asako much to Ichiro's shock.
Kinder and the robot clown reunite that night in a junkyard but are soon confronted by policemen and SGM members, leading to the robot clown accidentally electrocuting himself during the chaos against an outdoor electrical board. Just before its destruction, however, the robot tosses Kinder to safety.
The Invaders' latest operation involved the enlarging of insects into mutant monsters with the use of cosmic radiation. The giant vermin were to spread disease and impede the planet's grain supply to ultimately cause a global famine. During the height of the crisis, the SGM were swamped with reports of the monstrous vermin's activity across Japan, including big ants damaging a fruit ranch in Izu.
- While the big ants were only mentioned in dialog, they're a separate subspecies of 'big vermin' from the onscreen forms of Haebun, Gokibura, and Mothgojira, all of whom are based upon flies, cockroaches, and mosquitoes, respectively. This detail suggests The Invaders' plan involved more pest-types beyond the three.
Imitation Ultraman Leo
Imitation Ultraman Leo is a fake version of Ultraman Leo with currently unknown origins. He made his first and possibly only appearance in Primary School Hall "よいこ" in September of 1974.
Once normal everyday canines, the red dogs were brainwashed and physically transformed by Gorgo into rabid monsters who attack humans in mass while under the gorgosaurus' influence. The Izenborg team are forced to use their super-vehicles and sonic weapons to incapacitate the dogs and, later, after successfully slaying Gorgo, the mad animals return to normal.
Two hikers come across a cave deep within the mountains and quickly discover a nest of abnormally large bats alongside normal, regular-sized ones. Unfortunately for the explorers, the bats are transformed into ravenous killers by an observing Terrano, the bats quickly attacked and devoured the intruders, striping them down to a pile of bone and gore.
Under orders from Ururu, Terrano and his swarm of yellow bats destroy a radio tower and a power generator that knocks out the electricity in the nearby city: all this to disrupt a meeting between D-Force, the JSDF and government officials.
Surrounding the governmental building where the meeting is held, Terrano issues an ultimatum of surrender to the humans while the killer bats attempt to enter inside. However, the invading bats meet resistance by Ai Tachibana from within and the rest of the D-Force Izenborg team from without. Many of the yellow bats are killed in the conflict but the survivors fly back home after Terrano's own destruction, having been freed from the monster's mind-control.
After King Moa accidentally blew Mutusmi off an islet's cliff, causing her to fall into the ocean below, a giant shark circled the woman as she attempted to swim back to the rocky formation, before breaking the surface with a roar. King Moa swooped down and knocked the shark away, saving Mutusmi.
- While there seems to be unintended scaling issue with the creature animation, the shark ultimately appears to be twice as big as 77-meter-tall King Moa during their brief encounter.
- In episode 6 of the original Ultraman series, it was mentioned that a giant great white washed up on shore covered in wounds, thought to be caused by Guesra.
Prehistoric sauropod-like beast
While Amia shares the ancient history of humanity and their link to the Ultra People with the still recuperating Choichiro Hikari, the visual archives of U40's computers briefly shows a giant sauropod-like creature with red eyes and sharp teeth being speared by ancient U40 immigrants. According to Amia, this beast was just one of many prehistoric hazards that their respective ancestors contended with alongside extraterrestrial menaces like the Bader Group.
Unnamed trophy monster
Briefly appearing in episode 42 of The☆Ultraman is an unnamed alien monster of whom the space hunter Hatari had slain; the only one of his trophies that doesn't appear to be a prehistoric Earth animal. It's never made clear if this is a statue made in the monster's likeness or the stuffed and mounted beast itself. The trophy monster's design is a reworked Jinario.
In order to take direct control of Gerukadon, Gudis lured and entrapped Jimmy, Gerukadon's human friend, within a large glowing green pod made from his own genetic cells and projected a psychical yet soulless clone of the boy. The Jimmy clone guided Gerukadon's path of destruction and battle with Ultraman Great using a crystalline device also created by Gudis. With telepathic encouragement from Jack Shindo, the real Jimmy eventually broke free from Gudis' hold. Jimmy then took control of his own clone, forcing the copy to shatters the crystal and thus destroying itself and its influence over Gerukadon in the process.
The One Who Sleeps Below
Shortly after UMA launches a specialized satellite created to repair holes in the ozone layer, a mysterious red algae covers the oceans, killing all life it comes across. Jack Shindo and Jean Echo discover that the sea monster Kodalar is connected to the killer algae, having emerged to defend the Earth and take revenge on humanity for bringing devastation to the oceans. Additionally, UMA discovers an ancient metal disc near Kodalar's underwater lair, covered in mysterious inscriptions which reads: “One that was bound to the deep, One that was born to the sky, One shall be called from its sleep, and the darkness shall follow the cry”. The 'One that was born to the sky' soon reveals itself as the spacefaring dragon Kilazee, first seen from deep-space observation satellites. The identity of The One Who Sleeps Below, however, remains a mystery. Days later, Kilazee enters Earth's orbit, destroying cities from high above, while Kodalar began attacking coastal areas after successfully defeating Ultraman Great in battle.
As the chaos continued to escalate, UMA activated the ozone repair program as an attempt to calm the two monsters and ease their attack, but a massive energy pulse took place in the vicinity of the satellite system in charge of the operation, causing the skies across the world to flash in many bright colors and hum a strange rumbling noise. From this bizarre chain reaction, Colonel Arthur Grant of UMA realized who the third creature is: The One Who Sleeps Below is the very Earth itself. A sentient organism in its own right, the Earth has summoned Kilazee and Kodolar to serve as its apocalyptic avengers against the harmful presence of humanity.
- Heavily inspired by the Gaia Hypothesis, the concept of the planet Earth having living sentience and using created or conjured agents (giant monsters or otherwise) to protect itself from harmful elements like humanity has been explored in numerous fiction the world over. This same concept would later be revisited in the 23rd and 24th episodes of Ultraman Z, where a set of five monsters (King Guesra, Takkong, Demaaga, Gomess, and Pagos) were summoned by the Earth in an attempt to destroy Ultroid Zero.
- It's hinted in the start of Ultraman Max that humanity has over populated the Earth and it's now sending monsters to re-balance nature.
This one unnamed pink-skinned triclops appeared briefly in issue one of Nemesis Comics Ultraman: Towards the Future miniseries. As Ultraman Great flashes back to his past battles, the three-eyed monster is shown fighting the hero and alongside Majaba and a crawling Barrangas: an event that never occurs in the television series proper.
- The pink-skinned triclops is one of several original monsters who erroneously appears in the comics' flashback sequences to the television series, including Unidentified Aquatic Kaiju and Giant Shark.
- While this minor monster lacks an official name, online artist EarthBaragon has given it the fan-made moniker of Tridevo (tri as in three + devastation).
Plague of giant ants
A plague of monstrous ants are summoned by the evil will of a gigantic oni-like entity from space, menacing the countryside until their master's defeat at the hands of Ultraman Great where the ants' die off in mass. These creatures appeared briefly in only two panels of Ultraman: Negative One but little else is given in the actual story beyond said visuals.
UMA security robots
In an attempt to reach an oni-like enemy in space who's attacking the Earth below with his vast demonic powers, Jack Shindo and his martial artist friend Ace break into a UMA air force hanger at night in order to steal orbital jet fighters for their mission. After fighting off the hanger's armed guards, the two are then confronted by a pair of imposing security robots, twice their height and armed with laser-shooting visors. Narrowly dodging one of the robot's deadly eye-beams, Ace quickly disables the mechanical sentries with his shuriken.
Unlike the intelligent and heroic paramilitary group seen in the main television series, the UMA organization featured in the American comic spin-off is a vast worldwide military force undermine by totalitarianism and corruption, hence the presence of the fearsome robot guards and Shindo and Ace's need to steal from UMA after failing to receive help through official but otherwise antagonistic channels. This uncharacteristic take on UMA likely resulted from a lack of understanding of the source material and the grim and gritty story trends of comics back in the 1990s.
Clowns from the dream world
This sinister team of clowns were sentient hallucinations created by the monster Dazzlba and served as henchmen for Kahn Digifer and Takeshi Todo within the dream world that the three antagonists held dominion over. While looking human, the clowns were more bestial in nature, incapable of speech and making high-pitch grunts instead. They were extremely acrobatic in their fighting skills while also being armed with various handheld weapons.
After Gridman and his allies destroyed Dazzlba within Cyberspace, a dream world version of Gridman, imprisoned and awaiting execution, broke free from his restraints and battled the clowns, each of them fading away upon their defeat.
Takeshi Todo's computer
While present from the very first episode of Gridman the Hyper Agent, the personal computer of Takeshi Todo is forcefully transformed into a series of plant-like vines by Kahn Digifer in episode 38 after the two have a falling out with the greater villain taking extreme measures. Growing gigantic in mass, the monstrous computer breaks out of Takeshi's room and reaches for the stormy skies above, opening a dimensional portal between Earth and the Computer World so that Khan Digifer may invade the former realm. Fortunately, Gridman and his human allies, including the now reformed Takeshi, were able to vanquish Khan Digifer, causing the berserk machine-creature to deactivate and disappear.
Gigan appeared in a 1996 Children's Day stage show, taking sides with Alien Baltan, Alien Pitt, Alien Bado, and Bemstar to fight an assortment of heroes, including Ultraman. The suit was made in 1993. Gigan was also part of the Godzilla Megapowers in the 1993 Famicom game, Battle Baseball, along side fellow Toho Kaiju and aliens, crossing over with Ultraman's Ultra Starlights.
Reanimated animal corpses
In addition to creating the Deents, the mysterious green rain that showered the Hayami, Kanagawa region also reanimated several animal corpses including an accidently exposed butcher shop's chicken. While the undead creatures are never seen, nor their ultimate fates ever revealed, the KCB news crew attempted to reenact the butcher's encounter with the chicken however crudely with marionette-style puppetry.
Unnamed silhouetted monster
Appearing briefly as a silhouetted figure in flashback from episode 33 of Ultraman Cosmos, this destructive creature was responsible for the death of Junya Nagare's sister during a rampage, leading the former SRC member to become an independent hunter of monsters regardless if said creatures were malevolent or benevolent. The monster is a reused Algona suit from the otherwise unconnected series Ultraman Gaia.
The Merliger (マーライガー Māraigā) is the manifestation of the Merlion's spirit and the guardian deity of Singapore that first appears in the web miniseries Ultraman: A New Power of Singapore. It aided Ultraman in defending Singapore against Red King, Gubila and Neronga.
- Merliger's suit is slightly modified from Gukulushisa's.
