- Badass Pacifist: Whereas other Ultramen are warriors who usually kill the monsters and aliens they battle, Cosmos prefers not to use violence and instead usually attempts to purify or pacify his opponents.
- Blue Is Heroic: His main color is a light blue and he is a pure-hearted and kind individual who seeks harmony and the coexistance of living beings.
- Beware the Nice Ones: Cosmos is a pacifist who wants everyone to get along and rarely harbors hatred even towards his enemies, but anger him or hurt those that he cares for with malevolent intent and he will destroy you.
- Cosmic Motifs: Aside from his name being Cosmos (space), his forms are all based on celestial bodies. Luna and Corona are based on moon and sun, while eclipse is Exactly What It Says on the Tin. Also it's mentioned in the 2018 Ultraman Tiga, Dyna, and Gaia Novel that he draws his powers from the Sun and the Moon.
- Friend to All Living Things: Cosmos has dedicated his life to all creatures that seek to live peacefully with others. His only exceptions to this were Alien Nowar, Alien Waroga, Sandros, Alien Bat, Etelgar and formerly Chaos Header (before Musashi helped him find a way to redeem it).
- Gentle Giant: Even by Ultraman standards, Cosmos is gentle and kind, only killing his enemies if no peaceful solutions can be achieved. In fact, he has the lowest kill ratio of all Ultras, with only a few genuinely evil/unredeemable enemies being killed.
- Literal Split Personality: It's alluded to through All There in the Manual and eventually confirmed in Ultra Galaxy Fight: The Absolute Conspiracy that Cosmos is actually the result of Ultraman Legend splitting in two to become him and Justice.
- Martial Pacifist: Cosmos often uses defensive maneuvers when battling, as he tries to avoid provoking fights and battles only to subdue his enemies.
- Multiform Balance: Cosmos has two forms he switches between depending on the situation.
- Squishy Wizard: Luna Mode, his default blue form, uses a variety of healing, purification, and calming powers in order to pacify berserk monsters. It is powered by Cosmos' own kindness.
- Jack-of-All-Stats: His Corona Mode, where he gains lots of red in overlap with his blue patterns. This form is powered by Cosmos' strength, and is mainly used if killing is the only way to end the conflict.
- Super Mode: His Eclipse Mode, which he gains in Episode 30. It combines the powers of Luna and Corona Mode through Musashi's own courage. However, it can only be used for one minute.
- OOC Is Serious Business: In Ultraman Saga, Cosmos fought in his Luna Mode form despite the form being incapable of strong attacks.
- Earlier in his own series, when the baby Arados dies saving him from Ragstone Mechalator, who was sent to kill Cosmos so Nowar could kidnap the baby Arados, Cosmos wordlessly destroys Nowar's spaceship with him on it for it.
- In general, if he goes all-out and foregoes his usual Martial Pacifist fighting style, you know he's been absolutely pissed off and will lay a smackdown on, if not outright destroy, those who dared to provoke him far.
- Technical Pacifist: His fighting style in Luna Mode and most of his forms relies heavily on defending himself and subduing his foes rather than hurting them.
The attack team of this series, EYES is a branch of the SRC (Scientific Research Circle), an organization dedicated to studying and protecting monsters and aliens. Thus, EYES is not a military squad and prefers to deal with monsters and aliens non-violently. However, they do carry weaponry and have fighting vehicles for defense and those times when they must battle the monsters. In the series' timeline, the group was established shortly after the events of the first movie in response to the appearance of Ultraman Cosmos.
The Main Team
- Played by: Taiyo Sugiura (in the series), Kounosuke Tokai (in First Contact)
- All-Loving Hero: In a manner similar to Cosmos. See Friend to All Living Things below. Even the seemingly pure evil that is Chaos Header doesn't earns his hatred. In fact, he is perfectly happy to forgive Julie/Ultraman Justice, despite them killing him and Cosmos and almost allowing Delacion to commit planetary genocide on Earth.
- Childhood Friends: A rare non-human example with Lidorias, the two met when Musashi was a kid and have remained friends with each other ever since.
- Decoy Protagonist: It appears that the Cosmos VS Justice movie focuses on Musashi, right? Wrong. The director reveals in the magazine that the true viewpoint character is Julie, aka. Ultraman Justice, which is better exemplified by him and Cosmos getting killed by Justice early on and only being revived at the beginning of the third act, once Justice and Julie have had their HeelFace Turn.
- Friend to All Living Things: Like Cosmos, Musashi believes that all beings, whether they be human, monster, animal, or alien, have a right to live in peace, even Chaos Header. Only a few legitimately evil aliens became aversions to his view due to their cruelty.
- The Heart: Musashi just wants everyone, humans, animals, Kaiju, aliens and other things alike to live in peace and harmony. He rarely harbors negative emotions towards someone and helps his teammates and others around him grow kinder and happier.
- The Hero: The series follows his dreams in pursuit of a world where all creatures, including kaiju, can live together peacefully.
- Martial Pacifist: Believes strongly in avoiding violence and fighting, which grows stronger as the series draws to a close as he even questions if killing Chaos Header is right.
- Official Couple: With Ayano. They even have a son by the time of Ultraman Saga.
- Positive Friend Influence: To everyone else in the series, his pacifism and niceness rubs off his teammates and helps them all not only become more forgiving and kind, but also to eventually solve their personal problems. Likewise, his kindness gets Ultraman Justice to view the errors of his extremism and even Cosmos tells him that Musashi has far more of a heart than he does, and that he owes his truest kindness to Musashi's own idealism.
- Played by: Daisuke Shima
- A Day in the Limelight: "The Alternate Dimension Trap" and "Gigi vs Gon".
- Beware the Nice Ones: Piss him off and he'll show you he's no slouch in a fight.
- The Captain: Of EYES.
- Frontline General: Ocasionally participates directly in the fights of EYES'.
- Supporting Leader: He tends to direct orders from the safety of EYES' Treasure Base.
- What the Hell, Hero?: Often is the one to directly call out the JADF on their unnecessary violence and hatred of monsters, that often results in innocent monsters being hurt/dying, and is willing to get physical to get his points across.
- Played by: Kaori Sakagami
- A Day in the Limelight: "The Legend of Mt. Nibito" and "The Magic Stone".
- Action Girl: In contrast to Ayano, who's usually stationed in base.
- Number Two: To Captain Hiura, as she leads the rest of the team out in the field.
- Played by: Koichi Sudo
- A Day in the Limelight: "Monster Fishing", "The Bronze Devil", "Wrath of the Sea God", and "The Miraculous Flower".
- Fat Comic Relief: Downplayed. He often has his moments as such, but is also legitimately a very intelligent person whose ideas have proven to be key to success on many occasions. Likewise, his struggles and issues with his father are not Played for Laughs beyond a few scenes and form a serious part of his character arcs.
- The Smart Guy: He creates the various technology and strategies that EYES uses against monsters, and also plays a role in researching the anti-Chaos Header antidote.
- Smart People Wear Glasses: Always bespectacled.
- "Well Done, Son!" Guy: His relationship with his father, who he feels doesn't appreciate his achievements as an EYES scientist enough to care.
- Played by: Mayuka Suzuki
- A Day in the Limelight: "The Sleeping Girl", "Warm Memories", and "The Amusement Park Legend"
- Bridge Bunnies: She's typically stationed at EYES' computer and communications bridge.
- Genki Girl: She's a cheerful and chatty girl full of energy and good feelings.
- Mission Control: She rarely ever goes out onto the field.
- Official Couple: With Musashi. They have a son by the time of Ultraman Saga.
- Played by: Hidekazu Ichinose
- A Day in the Limelight: "Revenge of the Fireflies", "Fubuki Retires?!", "The Green Fugitive", and "Sorceress of the Sky".
- Freudian Excuse: He was born a sickly, weak child; who then grew up to believe that strength was the only way to get through in life.
- Grumpy Bear: In contrast to the more lighthearted nature of the show and most of its cast, Fubuki tends to be rather dour and cynical. This eventually starts to fade away with his Character Development and growing kindness.
- The Rival: With Musashi. Hiura likes to make them work together, but Fubuki finds Musashi's pacifistic attitude to be naive. Though this fades as the series progresses and Fubuki grows to appreciate and embrace the pacifist ideals of Musashi.
- Took a Level in Kindness: As the series progresses he goes from opposing Musashi's ideals to fully embracing them and seeing Musashi as a close and true friend, rather than a rival. Likewise, when he is ascended to the position of Captain, he maintains the pacifist ideals of Musashi.
Dr. Noboru Kawaya
- Played by: Shigeki Kagemaru
- Chivalrous Pervert: Despite his playboy attitude, Dr. Kawaya is very loyal to the women he loves. Best shown in his debut, where he takes a bullet for the Alien Srayu Lamia to save her from JADF officers.
- The Medic: He serves as EYES' doctor.
IkeyamaA close friend of Musashi who works in SRC's Monster Observation Facility on the Kapuya Islands where many of the monsters pacified by Cosmos dwell.
In GeneralAnother faction in charge of dealing with Kaiju, unlike EYES, prefer to utilize brute force and kill Kaiju outright. They often clash with EYES on how to deal with Kaiju.
Commander SaharaThe leading figure of JADF. Despite his position, he's fairly reasonable and is willing to listen to EYES' advice more often than most of his subordinates.
- Reasonable Authority Figure: Compared to most of his fellow JADF members, he takes far less convincing in order to work alongside EYES.
Vice-Commander ShishikuraSahara's right-hand man, and equally as reasonable in spite of his preferrence of violence against Kaiju.
Naval Officer SaijoAn arrogant, rude and stubborn officer under Sahara. Unlike his superiors, he dislikes having to work outright with EYES and often antagonizes them.
- Hate Sink: Like Shigemura before him. He's arrogant, rude, stubborn even when proven wrong and usually makes the situation at hand worse by employing unnecessary violence even when the situation has been de-escalated.
- Humans Are Bastards: Unlike most humans, he's straight-up unlikable with little to no redeeming qualities of any kind.
- Smug Snake: In spite of his inability to ever solve the problems of save the day, he will insist that EYES are "incompetent" and keep trying to overtake their operations.
- Suspiciously Similar Substitute: To Shigemura, being an irrational, petty and smug officer who makes things harder for EYES to solve.
- First Appearance: Reunion with the LightVoiced by: Koji Haramaki
- The Assimilator: Chaos Header believes that the fact that all living creatures have differing thoughts is the ultimate cause of conflict, thus it infects them with its own essence, assimilating their minds into its own and creating "order".
- Barrier Warrior: Its final form, Chaos Darkness, can create a purple energy barrier to block attacks.
- Big Bad: Of the series proper.
- Bishōnen Line: A good example with its purified form, Chaos Header 0, which is angelical and more humanoid looking than its previous transformations.
- The Corruption: Chaos Header transforms creatures into evil and twisted versions of themselves that Cosmos has to either purify or destroy depending on the situation.
- It can also create evil versions of beings it infects if it chooses to.
- Demonic Possession: Chaos Header specializes in taking over the bodies of other creatures — humans, animals, monsters, aliens, and even robots. In their corrupted forms, they become uncontrollably evil and often gain new powers or a demonic appearance.
- Eldritch Abomination: A mass of virus-like beings that seek to corrupt all beings in the universe in order to form a new cosmic order.
- Energy Absorption: In its physical forms, Chaos Header is able to drain energy from Ultraman Cosmos, which it uses in its first battle with him to analyze Cosmos' powers and combat tactics.
- Later on, it absorbs some of Cosmos' energy attacks to grow more powerful and even absorbs some of Cosmos' light to become Chaos Ultraman.
- Energy Being: Since the microorganisms that compose its body are made of a light-like substance.
- Evil Cannot Comprehend Good: As Musashi observes in Episode 26, Chaos Header is fascinated with negative human emotions like anger and sadness, but happiness and love disturb and confuse it to the point of weakening.
- Evil Knockoff: When not corrupting other beings, Chaos Header instead creates an evil doppelganger of them, which it does to Golmede, Parastan, and Eligal. However, Chaos Header need to collect their DNA to do this.
- Later on, Chaos Header absorbs some of Ultraman Cosmos' light from the Cosmos Pluck, allowing it to transform into the evil doppelganger, Chaos Ultraman (or Chaos Ultraman Calamity when it gets a power boost).
- Eye Beams: Chaos Header can fire bolts of chaos energy from its eyes in all its physical forms, which is derived from one of its abilities in its normal light form.
- Gone Horribly Wrong: As EYES learns from an alien document recovered from the ruins of a planet, Chaos Header was created by an exinct alien race to bring order to the universe. However, the entity believed order could only be achieved violently and imposed its will by devastating planets and corrupting or killing native lifeforms as a result.
- Good Hurts Evil: Positive emotions weaken Chaos Header's infections over anything that its corrupted.
- In the finale, Musashi discovers that Chaos Header's capacity for evil suggests a capacity for goodness, so as he tries to tap into the goodness in Chaos Header's heart alongside the cries of his monster friends, causing the entity to become temporarily stunned with each attempt. Though it's averted when Cosmos uses a Full Moon Rect on the weakened Chaos Header, as it purifies the entity into a being of good.
- Guardian Entity: As Chaos Header 0, as it serves as the guardian of Planet Juran, watching over both Kaiju and humans.
- Hand Blast: Chaos Darkness, possesses a number of such abilities; all very powerful.
- The Chaos Light Bullets are small energy blasts that can cause large explosions, covering several city blocks with fire.
- The Dark Destroyer charges up a massive energy ball that fire with tremendous force, pushing back whatever it hits hundreds of yards. It even shattered Cosmos' Golden Barrier!
- The Crimson Break is done with red energy blasts shot into the ground, creating a massive, explosive fissure of chaos energy.
- HeelFace Turn: After managing to find Chaos Header's hidden goodness, Musashi ultimately purifies the villain, transforming the evil entity into the angelic Chaos Header Zero. As Chaos Header thanks Musashi for the deed, even Ultraman Cosmos is left impressed by Musashi for his determination to redeem the villain — something that even he never considered.
- Taken a step further in Ultraman Saga, where Musashi reveals that the redeemed Chaos Header has become the new guardian of a rejuvenated Juran, watching over the planet-turned-monster sanctuary and protecting its inhabitants.
- I Am Legion: Whenever Chaos Header speaks, it refers himself as "we", as it's a hive mind of tiny but malevolent microorganisms. After becoming Chaos Header 0 this is no longer its way of speaking, however.
- Kryptonite Factor: The reason why Chaos Header cannot infect the same victims over and over again is because they develop an antibody that makes them immune (or at least highly resistant) to Chaos Header's corruption. As the series progresses, EYES researches the anitbodies in hopes of creating a formula that will destroy Chaos Header.
- Chaos Header is also weakened by a type of mineral found on the Moon dubbed SOAAG by EYES, which the team combines with the antibody and Mazalgas' Chaos Chimera enzyme during the events of the finale.
- Light Is Not Good: Its most basic form resembles particles of bright light, which EYES initially assumes to be some kind of marvelous cosmic spectacle when it first appears. Then said light releases a beam of energy that destroys an entire city!
- Averted with Chaos Header 0, its purified form, which is colored a bright golden and is a being of pure good, going as far as becoming a Guardian Entity on Juran.
- Mind over Matter: In its physical forms, Chaos Header can fire waves of telekinetic energy that force push whatever they hit. They get more powerful with each new form, eventually escalating to outright telekinesis.
- One-Winged Angel: Three times in the series Chaos Header take on a dark and demonic physical form to battle Ultraman Cosmos.
- The first was in "The Power to Defeat Chaos" as Chaos Header Iblis.
- Second was as Chaos Header Mebut in "Dreaming of Courage".
- Finally, as Chaos Darkness in the series finale.
- The Power of Hate: Chaos Header manifests in physical forms if it has absorbed a sufficient amount of negative emotions. If not sacrificing a living being will do instead.
- In the finale, Chaps Header its own hatred for Ultraman Cosmos to become Chaos Darkness.
- Red Eyes, Take Warning: In all its physical forms, though whenever Chaos Header forms a face in its light form, it has this trait.
- Also, those infected by it or its creations have them as well.
- Well-Intentioned Extremist: It seeks absolute order, and believes that infecting all creatures with its virus and extinguishing free will is going to achieve that goal.
- First Appearance: Reunion with the Light
- Benevolent Monsters: Like many kaiju in this series, Lidorias is a gentle creature that will help humans if necessary. Naturally, this makes it the first target of Chaos Header.
- Breakout Character: Lidorias is the most iconic monster in Ultraman Cosmos and often appears in merchandise or makes background appearances in other series whenever Cosmos makes an appearance, though obviously being a peaceful monster, she hasn't been placed against any other Ultra heroes and usually appears as a cameo alongside fellow monsters, Golmede, Mogrudon and Bolgils.
- Breath Weapon: Breathes a beam of blue energy.
- Gentle Giant: Establishing one of the major tropes for kaiju in this series, Lidorias is a purely peaceful monster that does not actively seek to attack humans and is quite friendly with Musashi Haruno.
- Giant Flyer: Like all bird kaiju.
- Homage: Lidorias is based on Litra (note the similarity of their names) from Ultra Q, another benevolent bird kaiju who is enemies with a brutish and aggressive reptilian Kaiju.
- Superpowered Evil Side: Chaos Lidorias, the first creation of Chaos Header.
- Undying Loyalty: Lidorias is extremely loyal to Musashi. A few times in the series, Lidorias will sense that Musashi is in danger and fly all the way from the Kapuya Islands in order to fight whatever monster is endangering her human friend.
- First Appearance: Chaos Header's Shadow
- Archenemy: Of Lidorias. Though that doesn't stop him from teaming up with her when the Glokers invader Earth Ultraman Cosmos vs Ultraman Justice.
- Art Evolution: The second Golmede is covered in light yellowy blothces around its neck and limbs in comparison to the original Golmede's fully brown skin.
- Breath Weapon: Breathes fire.
- Energy Absorption: Gains this ability as Golmede Beta due to the JADF's cruel experiments on it, absorbing any and all attacks and their energy to increase its strength and that of its flame breath. However, Golmede Beta must constantly replenish its energy as a result, putting the kaiju in a perpetual state of agony as its energy perpetually diminishes to near-fatal levels.
- Everything's Better with Dinosaurs: Which is a given, since he's based off the Ultra Series' very first monster, Gomess.
- Evil Knockoff: Chaos Header creates Chaos Golmede by collecting its DNA and corrupting it into a new creature.
- Homage: Of Gomess from Ultra Q, another dinosaur-like kaiju with a peaceful bird kaiju as its archenemy.
- Non-Malicious Monster: Although Golmede can be a dangerous and violent creature if aroused to anger (such as being awoken b Chaos Header or tortured by the JADF), it is content to keep to itself and prefers to stay away from humans.
- Tragic Monster: Golmede Beta, full stop. EYES is disgusted by the JADF abusing and torturing the monster into a living weapon, and Musashi is especially saddened by the monster's pain and torment, considering it to be the equivalent of a frightened and wounded animal.
- Tunnel King: Gomede prefers to stay underground, only coming up to the surface when disturbed.
- First Appearance: Fly, Musashi!
- Achilles' Heel: Has a small bright red organ on the back of its neck that is particularly sensitive to anesthetic.
- Homage: Its cone-head armour design is inspired by Gabora from the original Ultraman.
- Monster Is a Mommy: It had an egg underground near the airport, which is why it refused to leave the area despite the sounds of airplanes disturbing it.
- Non-Malicious Monster: Musashi discovers that Spittle was rampaging because the sounds of airplanes flying above it were driving it crazy, so EYES and Cosmos decide to move the monster and its egg somewhere else instead.
- Super Spit: As Spittle's name suggests, it relies mainly on its slime-like spit, which has explosive properties.
- Tunnel King: Its a very fast burrower, able to make quick u-turns and escape by digging in a matter of minutes.
- First Appearance: The Fallen RobotVoiced by: Hiroshi Ishi
- Cool Toy: And they don't get much cooler than a kaiju-sized alien robot!
- Good Old Robot: Played with. Igomas' owner got rid of him because he was completely obsolete (the batteries he needed were no longer available) and treated him as garbage to be tossed away. However, the children he befriends consider him their dear friend regardless of his obsolescence, and when Igomas "dies", they decide to keep him around and work towards making it a new battery so future generations will be able play to play with it.
- Humongous Mecha: Correction. Humongous toy mecha.
- Living Toys: Although Igomas is just a toy, he is fully self-aware, has a human-like personality, and is capable of learning and sympathizing with others.
- My Little Panzer: Justified, as his owners were absolutely gargantuan aliens, so Igomas would be mere action figures to them.
- Transforming Mecha: He spends most of the episode is a compacted form resembling a strange-looking building.
- What Measure Is a Non-Human?: Igomas was treated as replaceable merchandise by his alien owners despite being as intelligent as a human, while the kids consider him an equal and are deeply saddened by Igomas' anger at his own obsolescence. Helps that when he runs out of battery, it's treated as a death and the kids hope to eventually fabricate a battery so Igomas can be played with by future generations.

- Master of Illusion: Mogrudon's chest is covered in bright patterns that cause hallucinations when it rears up and flashes them at its foes.
- Non-Malicious Monster: Mogrudon was only rampaging because humans had disturbed its sleep, and is otherwise, a peaceful kaiju.
- Prehensile Tail: Its tail is five times longer than its body, allowing Mogrudon to use its tail as a rope to constrict enemies.
- Tail Slap: Mogrudon's preferred tactic. It particularly likes to hide underground with only its tail exposed, using it to slap enemies while the rest of its body remains hidden.
- Tunnel King: Since its a mole kaiju.

- Homage: The Minins are based on friendly little Pigmon while Gamoran serves as an homage to the violent Garamon, since Pigmon and Garamon were created using the exact same suit.
- Shock and Awe: The Bio Controller allows Gamoran to shoot lightning bolts from its head.

- First Appearance: Forest of Friends
- Bigfoot, Sasquatch and Yeti: Looks the part.
- Friend to All Children: Yamawarawa prefers to make itself only visible to children and likes to make friends with any children he meets in the forest. However, he has a hard time accepting the fact that when the kids grow up, they will forget about him and just consider him a fairy tale — something that both angers and saddens him.
- Hulking Out: When angered, Yamawarawa changes his size to that of a kaiju and increases the length of his horns and shoulder spikes.
- I Just Want to Have Friends: The reason why he likes to befriend children he encounters in the forest is because he doesn't like being lonely. It's also why Yamawarawa is saddened when the children he befriends grow up and forget about him.
- Invisible to Adults: According to local legend, though it seems the reality is that he simply likes to hide from adults.
- Tastes Like Friendship: Yamawarawa likes to hand out offerings of fruit to those he wishes to befriend.
- Youkai: Named after a type of mountain-dwelling spirit resembling a hairy one-eyed dwarf.
- First Appearance: The Bronze Devil
- Energy Absorption: Absorbs stress in the form of energy, but too much of it makes it violent.
- Eye Beams: When in its kaiju form, Geshot can fire out the stress it has absorbed in the form of laser blasts. They don't harm people but they do cause people to become stressful and take it out violently. They also come in a limited amount based on how much stress Geshot has absorbed.
- Gone Horribly Right: Humans sealed inside an enchanted glass container because even though it was extremely effective at removing stress, Geshot had no way relieving the stress it absorbed.
- Hate Plague: Its eye beams cause stress so intense that people hit by them become extremely angry and violent.
- Golem: Based on Dogū.
- Make My Monster Grow: Stress causes its size to increase.
- Teleport Spam: In its statuette form, but only if it has absorbed enough stress to become animate.
- First Appearance: Move, Monster!
- Dem Bones: It's a fossil skeleton animated by its own unwillingness to die without seeing its child one last time.
- Everything's Better with Dinosaurs: Though it belongs to a fictional species.
- Gentle Giant: Mudon's species is stated to be herbivorous and they live in family groups, so the kaiju is completely peaceful. However, it does go berserk in the climax as it is angry that the fossils of its child were taken from it.
- Homage: Mudon borrows heavily from Seabozu and Skydon, in its appearance and how EYES deals with it respectively.
- Horn Attack: During its battle with Ultraman Cosmos, it manages to gore him badly enough that Cosmos is forced to retreat!
- Monster Is a Mommy: Turns out to be a mother dinosaur whose child's fossils were taken away from it, so it refused to move from the site they were buried until it became angry at humans for taking away the bones and rampaged. So EYES creates a model of the child's skeleton that Cosmos brings to life.
- No Body Left Behind: Mudon dissolves into a pile of powdered stone after being united with its child.
- Punny Name: Ayano came up with its name from "Don't move" with the syllables reversed, as Mudon doesn't move out of the tunnel it was found in (at least until the episode's climax).
- Tears of Joy: Upon reuniting with her baby.
- First Appearance: The Brightness of Life
- Big Creepy-Crawlies: A mayfly, in this case.
- Gentle Giant: It is a peaceful kaiju whose only goal is to lay its egg. This doesn't stop the JADF from trying to destroy it though. Tragically, they succeed, but the egg survives and is sent to be cared for at the Kapuya Islands.
- Meaningful Name: As Fubuki explains, it's name is derived from Greek for "living for only a day".
- Non-Malicious Monster: Ephemera destroys an abandoned factory in its infant stage, but that's the only destruction it causes (with no casualties). It then proceeds to play with the rubble until it reaches adult stage, where it begins to build a nest from the wreckage for the next Ephemera.
- Shock and Awe: Can shoot lightning from its antennae if angered.
- First Appearance: The Daughter of Time Pt. 1

- Blade Below the Shoulder: His arms end in a pair of sword-like appendages that can also shoot laser bolts.
- Hand Blast: Can shoot purple lasers from his claws.
- Invisibility: Waroga uses this in the battle against Cosmos to baffle him. However, his reflection is still visible in the lake nearby, allowing Cosmos to strike him down.
- Mind Control: Uses this on Galbas and Reni by implanting microchips in their brains. However, Reni is more of a sleeper agent, but Musashi's kindness towards her means she never turns against him.
- Red Eyes, Take Warning: His sole facial feature.
- Shock and Awe: Can shoot lightning from his eyes.
- Vader Breath: His "roar".
- Voluntary Shapeshifting: In order to fly, he can transform himself into an orb of purple energy with only his red eyes visible.

- Everything's Better with Dinosaurs: Resembles one with large ears added.
- Non-Malicious Monster: Galbas is normally a peaceful monster, but starts rampaging due to Alien Waroga's mind control, although the JADF doesn't care and will have it killed either way.
- Tunnel King: Normally lived underground, so naturally,, Galbas is a good burrower.
- First Appearance: Deep Sea Fight
- Breath Weapon: Breathes a beam of orange energy. It can also shoot that same beam from its shell.

- Superpowered Evil Side: Chaos Jelga, which has no physical differences from the normal Jelga.
- Sea Monster: Sort of a sea snail mixed with an anglerfish.
- First Appearance: The Flying Whale

- Energy Absorption: Chaos Jirak can absorb beam attacks, as Cosmos finds out when he manages to reflect its Breath Weapon back.
- Flechette Storm: Chaos Jirak can spit out a storm of glass swords from its mouth.
- Flying Seafood Special: A whale, in this case.
- One-Winged Angel: Chaos Jirak gains a more humanoid form due to being merged with Akane, with the only whale features remaining being on its backside and the ridges on its chest and shoulders (which resemble a whale's belly).
- The Power of Hate: Chaos Jirak is virtually unstoppable due to Akane's intense hatred and disillusionment at having her hopes and dreams crushed by her friends. It's only after a passionate speech by her friends about following your dreams does Akane finally become calm enough for Cosmos to purify Chaos Jirak.
- Red Eyes, Take Warning: As Chaos Jirak, since it's a Chaos Header monster.
- Shock and Awe: Chaos Jirak can channel electricity through its whip.

- Doppelgänger Spin: Their super speed can create illusions of themselves.
- Cyclops: Soldier-Type Gigi come in three variations: red-eyed, blue-eyed ones, and yellow-eyed. The former two have only one visor-shaped eye, while the latter has bulging eyes. Scientist-Types like Dr. XX01 only come in a single variation — two small magenta eyes.
- Eye Beams: Soldier-Types can fire beams from their eyes (yellow, blue, or red, depending on the colour of the individuals eyes). In giant form, the Gigi can rotate their three faces rapidly to fire a barrage of beams.

- Intangibility: They can can phase through walls at will.
- Pokémon Speak: They only say "gi-gi" unless they're wearing their translation devices.
- Samus Is a Girl: Dr XX01 is revealed at the last minute to be female. EYES didn't realize it because her translation device had a masculine voice.
- Scientist vs. Soldier: Their entire society is based on this. As Dr. XX01 explains, they are completely divided between Soldier-Type and Scientist-Type, with the two groups divided on whether their species should migrate to Earth.
- Shrink Ray: Their preferred weapon. However, it can also do the reverse if the Gigi wielding it chooses to use it that way. Dr. XX01 uses it to turn Clevergon into a giant to assist Cosmos against the Soldier-Types.
- Super Speed: They move so quickly they look like they're teleporting.
- Translator Collar: The Gigi wear these to communicate with the human characters.
- First Appearance: The Legend of Mt. NibitoVoiced by: Miho Aoyama and Tadashi Katsumata

- Tragic Monster: Case in point: When Captain Hiura explains the backstory of Renki, Ayano feels great pity for Renki, comparing the story to Romeo and Juliet. Vice-Captain Shinobu also shows great sympathy towards Renki, and it is her speech on the trials of love that puts the ghosts to rest.
- Voice of the Legion: Renki speaks in two voices at once — that of the samurai and that of the princess.

- Non-Malicious Monster: Bolgils was only rampaging because it was hungry for a particularly rich source of energy, but is otherwise a completely peaceful kaiju.

- Non-Malicious Monster: Gelworm was just trying to get back to the meteorite it came from without any intention of harming people because a female of some relation it loves (the characters ponder whether it was its mate, mother, sister, or girlfriend) is still trapped on the meteorite.
- Sizeshifter: The reason why Gelworm is able to take on the form of humans despite being so tiny that people can't even feel it crawling on their shoulder. Eventually, it goes berserk in the climax and turns itself kaiju-sized.

- Right Hand of Doom: Its left hand is a massive pincer.
- Transforming Mecha: Guinje's normal form is a spaceship.
- First Appearance: A Space Monster is Born on Earth
- Gentle Giant: Zaranga is a completely peaceful creature, so the only work EYES and Cosmos had to do was get it to the ocean safely without anyone getting hurt.
- Playing with Fire: Zaranga's body temperature increases the closer it gets to childbirth, causing it to scorch the ground with its footsteps, burn anything in comes in contact with, and gain the ability to breath fire. Because, this intense heat can be fatal to her, it needs to give birth in the ocean to cool off.
- First Appearance: Strength and Power
- Breath Weapon: Breathes a poisonous gas with explosive properties.
- Evil Knockoff: Chaos Eligal, which Chaos Header creates to battle Cosmos after Eligal is subdued. Later, Chaos Header takes on the form of Chaos Eligal to lure Cosmos into a trap.

- Dishing Out Dirt: Reycura can launch explosive boulders from its fists.
- Gaia's Vengeance: Created to punish those who pollute the ocean. However, its creators do allow those who awaken it to redeem themselves by taking the mystic conch that controls Reycura and placing it at the god's stone shrine to deactivate the monster.
- Golem: A huge statue of an ocean deity made to carry out the god's wrath and will.
- Living Statue: Since it's meant to be the civilization's sea god in statue form that's usually half-buried at the bottom of the ocean.

- First Appearance: The Magic Stone
- Cyborg: As Ragstone Mechalator.
- Cyclops: Has only one orange eye.
- Emotion Eater: Ragstone consumes the emotions of those it mind controls, turning them into pseudo-robots that gain increased intelligence or athleticism in return. It becomes more powerful the more emotions it consumes and its spaceship can gather emotion energy to further power up Ragstone.
- Eye Beams: Shoots a beam of energy from its eye that drains emotions and mind controls people.
- The Juggernaut: It was completely unfazed by Cosmos Eclipse Mode's Naybuster Ray!
- Mind Control: What it does to humans in order to feed on their emotions.
- Our Monsters Are Weird: It's a one-eyed alien rock monster that feeds on emotions and turns people into mindless zombies!
- Rock Monster: An extraterrestrial one.
- Villain: Exit, Stage Left: Cosmos manages to purify Ragstone, driving out all the emotions it has consumed back into its victims bodies, forcing the monster to go back into its spaceship and leave Earth. Ragstone does end up returning when Alien Nowar turns it into a cyborg though.
- Voluntary Shapeshifting: It can disguise itself as a small orange stone with a single eye and small spikes, allowing it to still fire its eye beams. Its spaceship disguises itself as a bizarre-looking temple for its "worshipers" as well.
- You Have Failed Me: After Ragstone flees Cosmos, Alien Nowar uses the same torturous methods of creating cyborgs he does on other monsters to create Ragstone Mechalator as punishment.
- First Appearance: The Mountain of Youkai
- Archenemy: Of Yamawarawa.
- Badass Normal: Despite possessing no powers, Mahagenom was strong enough that Ultraman Cosmos and EYES needed help from Yamawarawa to defeat him, and even then, the best they could do was simply imprison it again.
- Red and Black and Evil All Over: Almost completely red and black, and indeed, very much evil.
- Sealed Evil in a Can: Was imprisoned by Yamawarawa long ago underneath a mountain near Hidaka Village, but eventually escaped to rampage again. However, only Yamawarawa knows the ritual to re-imprison Mahagenom.
- Youkai: Dosn't seem to be based on any examples from real-world folklore though.

- In a Single Bound: Able to leap good distances, almost like a frog.
- Non-Malicious Monster: Although Taildas is first seen rampaging without any explanation, the kaiju is not a malevolent creature — just a panicked one.
- Superpowered Evil Side: Chaos Taildas.
- Red Eyes, Take Warning: The sole difference of Chaos Taildas from the normal one is its red eyes

- A.I. Is a Crapshoot: Hellzking Revised remembers the purpose of the original Hellzking, causing the robot to go rogue.

- Organic Technology: Doigaki's analysis of the monster's composition reveals that Hellzking is less of a machine and more of a living being with robotic qualities.
- Transforming Mecha: Hellzking's usual form is a three-pronged spaceship. However, to transform, it completely restructures itself rather than sprouting limbs and a head lie most examples.
- First Appearance: Old Man AlienVoiced by: Shoichiro Akaboshi (also human form actor)
- Aliens Among Us: The problem for Musashi is he doesn't know who's the alien!

- Starfish Aliens: Their true form is a bizarre floating creature with tentacles of energy.
- Trademark Favorite Food: The Beryl aliens really love takoyaki.

- Whip It Good: In an attempt to defend herself from Exter Raider, she creates a green energy whip with her hands, though it does little to heed the android bounty hunter.
- First Appearance: The Green FugitivePortrayed by: Koichi Sugisaki
- Bounty Hunter: The unseen Exter aliens hired him to kill all their enemies.
- Deceptively Human Robots: Technically Human Alien robots, but for an advanced killer android, he's completely emotionless and unquestioning in orders like a lesser robot.

- Summon Bigger Fish: Immediately calls Sidebackter to Earth upon his death.

- He Who Must Not Be Seen: He and his father wear robes that conceal their bodies for the episode, and all shots of him are from behind or the side. Only at the very end does he finally remove his hood, revealing white hair and pointy ears, but we see very little beyond that.
- First Appearance: Puppet MonsterVoiced by: Tetsu Inada (also human form actor)
- Lack of Empathy: Alien Nowar cares nothing about the horrifying pain that is inflicted upon the monsters he turns into cyborgs. In fact, he is legitimately baffled at the fact that humans have not considered doing this to their planet's kaiju.

- The Mirror Shows Your True Self: In his human disguise, he still takes on his true form in front of a mirror. Also, shooting his reflection will harm him.
- Vile Villain, Saccharine Show: In a show that's notably Lighter and Softer, Alien Nowar stands out as one of the darkest antagonist in the franchise. Enslaving, torturing, eventually killing hundreds of innocent monsters for their own personal gain.

- Aliens Among Us: It turns out in the end that Mugera is actually an alien and his species has come back to Earth to to pick him up with the closing of the amusement park.

- Brainwashed and Crazy: As a result of his flowers being tainted by the meteorite's dust, he briefly becomes a rampaging giant whenever he gathers from them.
- Hand Blast: Can shoot purple lasers from his hands capable of causing fairly large explosions.
- Mercy Kill: He begs Musashi to turn into Cosmos and kill him to put an end to his insanity episodes, but Musashi refuses, saying that Cosmos cannot kill other beings without reason. Instead, Cosmos purifies both Kyulia and his flowers, allowing him to remain as village doctor for many more years to come.
- Nice Guy: He had actually just landed on Earth by accident, but came to love the people of the planet as much as Ultraman Cosmos does,. He is also more concerned about what his berserk episodes will do to the villagers than him.
- Really 700 Years Old: He's been living among the villagers for 300 years.
- First Appearance: Sorceress of the SkyVoiced by: Junichi Kawamoto (male), Nami Ishibashi (female)
- Bizarre Sexual Dimorphism: Let us make this as clear as possible — the male is the Ultraman-like humanoid with the pointed chest and the female is the bloodsucking pair of wings with the red eyes, and they are the same species.
- Brains and Brawn: The female is the brains (she does much of the communication with the human characters) and the male is the brawn (he mainly does the fighting with Ultraman Cosmos).
- Driven to Suicide: The original male dies this way
- Eye Beams: The female has this ability.
- Hand Blast: The male can shoot laser beams from his claws.
- Mind Control: The female possesses the ability to hypnotize humans into doing her bidding, although taking the form of their loved ones certainly helped out.
- Our Vampires Are Different: The female drinks blood to survive (by biting the victim's neck) and can impersonate other people to get around on Earth, all while acting as a symbiote with the humanoid male.

- Wolverine Claws: The male is equipped with these.
- First Appearance: The Snow of Space
- Big Creepy-Crawlies: Resembles a giant firefly.
- Breath Weapon: Breathes fire.
- Female Monster Surprise: After Alukela dies, it turns out to have been a mother as its body releases thousands of Snow Stars (the creature's larval stage) that fly into space.
- Non-Malicious Monster: Alukela does destroy a few buildings and attack EYES, but only because the team attacked it. In fact, as Alukela is dying, its cells suddenly begin to evolve, leading EYES to try destroy it out of fear of it metamorphosing into something worse and consequently causing the monster to regain all its strength and begin rampaging again.
- Spell My Name with an "S": Also called Alkela.
- First Appearance: Monster Smuggling!?
- Everything's Better with Dinosaurs: At the very least, it strongly resembles one.
- Make My Monster Grow: Vadata is only about 50 centimeters tall when first discovered by the smugglers, but by injecting it with powerful tranquilizers, it ends up growing to 59 meters! Unfortunately, it also makes him more violent.
- Non-Malicious Monster: Vadata is a peaceful monster, but poisons or drugs in its body cause it to become berserk, especially if they're very strong chemicals. Cosmos thus defeats Vadata by purifying the tranquilizers out of its system.
- First Appearance: Enemy of Chaos
- Breath Weapon: Mazalgas can spit blue orbs of energy that explode in the air, sending a shower of smaller energy orbs raining toward the ground and exploding. As Chaos Mazalgas, these are switched out for bolts of chaos energy.
- Energy Absorption: Mazalgas' most potent power is its ability to absorb any form of energy by opening up the top of its head to suck it in. It used the ability to consume EYES' energy net, but more significantly for the team was its ability to even consume Chaos Header's essence without being corrupted, thanks to its Chaos Chimera enzyme. However, this power is weakened when Mazalgas is fatally weakened by the JADF's attacks.
- Non-Malicious Monster: Mazalgas is described by Musashi as "Chaos Header's natural enemy", but the creature is solely interested in finding food, not in the battle between good and evil. Otherwise, the worst Mazalgas does is smash a JADF ammunitions plant when Chaos Header lures its predator over in order to frighten the JADF into attacking the monster.
- Rolling Attack: Can curl itself into a ball-like form in order to fly through space.
- Superpowered Evil Side: Chaos Mazalgas, the result of the monster being injured to the point of being unable to use its Energy Absorption powers, thus letting Chaos Header possess it.
- Tail Slap: Liked using this ability in combat.
- First Appearance: Transformation Impossible!?
- Barrier Warrior: Like June, Zageru can produce a force field, but this ability is nullified by Earth's atmosphere.
- Breath Weapon: Breathes fire.
- Non-Malicious Monster: Most of the rampaging that Zageru does is solely because it is easily scared.
- Pet Monstrosity: Of June
Alien Koise June
- First Appearance: Transformation Impossible!?Portrayed by: Shiori Kanzaki
- Barrier Warrior: Her species has the natural ability to produce force fields, though this is rendered null by Earth's atmosphere.
- Human Aliens: Or at the very least, we never see her in her true form.
- First Appearance: Future Monster
- Gentle Giant: Arados are peaceful monsters that wander through time in family herds.
- Gigantic Adults, Tiny Babies: The infant is only about a meter tall, but the adults stand at around 40 meters.
- Time Master: Arados' primary powers, which are all concentrated in its shell patterns. It can open up portals to travel through time, freeze time in a single area, warp other creatures through time, and even reverse time on a target to bring them back from the dead!
- First Appearance: Human Transporter
- Doppelgänger Spin: Tablis' sole ability is to create an intangible illusion of itself from any distance, meaning the monster doesn't have to take actions, only the duplicate.
- Gentle Giant: A completely peaceful creature that only seeks to be reunited with a human it befriended so long ago. However, it (or rather its illusion) does begin to rampage when EYES attempts to use a hologram of Kana to fool the monster.
- First Appearance: The Final TestPortrayed by: Hitomi Akimoto
- Forced Sleep: She can shoot out a beam of yellow energy from her hands that puts targets to sleep. She uses this to quiet Lidorias when the bird monster becomes alarmed by her presence.
- Human Aliens: It's not clear if this was a form she had taken or not though.
- The Man Behind the Man: Her species had turned the Minins into Gamorans sent them to Earth to test if humans could solve problems peacefully, but since Ultraman Cosmos had interfered with the previous test, it needed to be done again.
- First Appearance: The Kappa's Village
- Friend to All Children: While his closest friend of all the villagers was actually an old man, Kawanoji loves to play with the children in sumo wrestling games.
- Hulking Out: Kawanoji can turn himself giant-sized when angered, though during the fight he makes a deal with Cosmos that if the hero wins, he will shrink himself back to normal size.
- Kappa: There have been a few kappa-like kaiju in the franchise, but Kawanoji is an example of the real deal. He even sumo wrestles Ultraman Cosmos!
- Non-Malicious Monster: Kawanoji is a very peaceful kappa, only going on a rampage when provoked by the human characters.
- First Appearance: The Door of Snow
- An Ice Person: Gruanfan's arrival when the Door of Snow opens is foretold by sudden heavy snowfall, even in the summer.
- Gentle Giant: Gruanfan is a completely peaceful monster that does no fighting or attacking. The only reason why Musashi turns into Cosmos is to help Gruanfan go back through the Door of Snow.
- Time Master: Gruanfan freezes time when it enters the physical world because of the incompatibility with the Memory World. While present time is frozen, the Memory World appears to whoever summoned it, replaying past time for them and turning the summoner into a memory once Gruanfan goes back through the Door of Snow. It is possible to avoid being frozen by Gruanfan though, if one closes their eyes the moment the monster enters the physical world.
- First Appearance: Cry of the Earth
- Breath Weapon: Breathes fire.
- Giant Flyer: Amazingly, Dolba is able to fly, despite its tiny wings.

- Played by: Ikkei Watanabe
- Adults Are Useless: The shinning example. To say Commander Shigemura is useless is like saying the Artic has snow. Its a fact.
- Armchair Military: Mostly commands his armies of drones and fighters from inside his office or in a military vehicle.
- Armies Are Evil: "Evil" may be a bit of a strong word to describe Shigemura and the JADF, but their hyper-militaristic approach to all monsters is always portrayed as stupid at best and heinous at worst.
- Armies Are Useless: More often than not Shigemura and the JADF make things worse against the weekly monsters, thanks to their highly aggressive natures.
- Dirty Coward: After realizing his direct assault on Baltan has resulted in the alien waking up and retaliating by attacking the city, Shigemura's next actions would be to turn tail and flee into a nearby military truck while Cosmos deals with Baltan.
- Expy: He's the closest audiences would get to a live-action Kent Mansley.
- Hate Sink: And how! He's an Obstructive Bureaucrat and General Ripper, who repeatedly insists that Violence Is the Only Option (despite the SRC proving him wrong more than once) and interferes the SRC's attempts to peacefully subdue harmless monsters, by ordering his army to launch missiles indiscriminately. He tries to humiliate Haruno Musashi in public, and confiscates the blue stone given by Ultraman Cosmos' for no reason. His approach of using violence in all situations ultimately instigates Basical Baltan - already subdued peacefully by SRC - into retaliating, forcing Ultraman Cosmos to eventually kill the alien. Shigemura eventually crossed the line when he tries launching a nuke on Ultraman Cosmos (who just killed Baltan and saved the city) while muttering "aliens should all be destroyed"... in a Taking You with Me last-ditch attempt, which overlaps with Too Dumb to Live, because Cosmos at the time is right in the middle of the heavily-populated city. He would very likely end up being court-martialed for his actions, which seems more like a Karma Houdini for this hopelessly incompetent Smug Snake.
- Humans Are the Real Monsters: In a movie containing giant monsters and alien invaders, the greatest threat to human life is still this lousy excuse of a human whose actions, from instigating peaceful, non-violent monsters into attacking the city to trying to launch a nuke on Ultraman Cosmos, provides majority of the conflict in the film itself.
- Jerkass: A very good one-word description for him.
- Lethally Stupid: Sadly, his idiocy causes more harm to innocent civilians than to himself.
- The Millstone: His sole contribution to the story includes interfering with the SRC, attacking a non-violent monster causing it to go on a rampage, launch an attack on Baltan (which has been proven to be dangerous, but doesn't have hostile intentions as of yet) convincing Baltan to retaliate and invade Earth, and trying to blow up Ultraman Cosmos with a nuke.
- Put on a Bus: He's absent in the sequels, likely from being demoted or expelled by the military from his actions in the first movie. Good, nobody is going to miss him.
- Sinister Shades: Wears sunglasses. Even in daytime. Makes the audience want to kick him in the face even more than they already do.
- Played by: Hidekazu Akai
- Big Fun: A large, muscular man with a very jovial personality.
- Boisterous Bruiser: A huge brute of a man, but also a fun-loving person and all-around supportive husband and father.
- Family Man: To both his wife and stepson.
- First Father Wins: Originally, Haruno only pins for his biological father and doesn't care much for Sergeant Haruno, but gradually the boy warms up to his stepdad.
- Good Stepmother: A Gender-inverted version, he's a (very) good and supportive stepfather to his stepson.
- Papa Wolf: Cares for his stepson Haruno Musashi as much as a biological one, even pummeling Commander Shigemura for threatening the boy.
- Put on a Bus: He's somehow absent in the later two movies.
- Reasonable Authority Figure: A police sergeant who is dedicated to his job.
- "Well Done, Dad!" Guy: He knows that he can never replace Musashi's late biological late father, but tries to live up to be a good stepdad to his son. By the end of the movie, Musashi had since decided to make peace with his depression and recognize Yujiro as a father.
- What Happened to the Mouse?: While the second movie explains his absence by stating he's retired, he's completely absent and not even mentioned in the third.
Musashi's childhood friend, who gets caught up in the plot of the Baltan Shirubyi. She returns in Ultraman Cosmos 2: The Blue Planet, as an adult where she befriends the Aliens Gyashi Jin and Shau, and in Ultraman Cosmos vs. Ultraman Justice: The Final Battle, to help EYES rescue Musashi.
- The Bus Came Back: She's absent in the TV series, but comes back in the second movie.
- Cheerful Child: Always optimistic and smiling as a kid, compared to Musashi who spends most of the film being upset over his missing father.
- Girlish Pigtails: Has cute, girlish pigtails as a child.
- Ironic Echo: During the night where Mari and the boys stays up late to watch an eclipse, Mari jokingly tells the boys not to get accidentally abducted by aliens. She ends up being the first of her class to meet the Baltanians when Baltan Shirubyi borrows her body as a vessel.
- Nice Girl: Possibly the nicest of the human supporting characters.
- One of the Boys: Usually hangs out with Musashi and other boys in school.
- People Puppets: Was used as a vessel by Baltan Shirubyi.
- She Is All Grown Up: When she returns and meets Haruno and the boys for the first time in the sequel movies, ever since 8 years ago.
- Tomboy with a Girly Streak: Is slightly tomboyish and more active than the other boys in her class, but wears a dress and feminine pigtails.
Alien Baltan Basical
- Voiced by: Daisuke Gōri
For tropes applying to the Baltans in general, see the Ultraman TV Series character sheet
- Alas, Poor Villain: Everyone feels pretty bad for him when he dies, including Ultraman Cosmos and the human characters (well, except Commander Shigemura), as they sympathize with his motives for trying to take over Earth and realize that with his death, the Baltan children are effectively leaderless and defenseless. Cosmos even helps the Baltan children with taking his body back to his homeworld for burial. To push the point further, Basical cries in his dying moments, fearing for the future of his people with his death.
- An Ice Person: Can shoot freezing beams from his claws that cause several fighter jets to shatter into pieces.
- Anti-Villain: Ultimately, he had the future of his species' children in his heart and mind when he decided to invade Earth.
- Art Evolution: Being an updated version of the classic Ultraman foe, Basical has larger horns resembling those of a stag beetle, as well as a more armored body, meant to resemble an insect's exoskeleton. He also sports cicada-like wings tucked onto his sides, sharp-ended feet, and insect-like joints. His proboscis also sticks out unlike other Baltan suits.
- Big Bad: Of Ultraman Cosmos: First Contact.
- Blade Below the Shoulder: As Neo Baltan, he gains a massive sword in place of his right arm. Said sword can also hurl glass blades.
- Healing Factor: When Ultraman Cosmos first enters Corona Mode, he tears off Basical's blade arm, only for it to regrow into a claw.
- Last of His Kind: He's the last remaining adult Baltan.
- Music Soothes the Savage Beast: As correctly deduced by Team SRC, they can pacify Baltan with music played from loudspeakers, and then attwmpt a peaceful communication with it. It works, until Commander Shigemura orders a drone attack on the sleeping Baltan.
- Mythology Gag: His backstory borrows many elements from Baltan's appearance in the second episode of Ultraman, such as having destroyed his own world and deciding to replace it with Earth, as well as having a spaceship with millions of smaller Baltans on board following behind him.
- One-Winged Angel: For his final battle with Ultraman Cosmos, he transforms himself into the monstrous Neo Baltan, gaining a more metallic appearance and a slew of new abilities.
- Planet Spaceship: His home, and the home of millions of Baltanian children.
- Shock and Awe: Can create lightning storms, but in Neo Baltan form, his energy whip can channel electric shocks.
- Spike Shooter: As Neo Baltan, Basical can create shoot out a storm of flechettes from his shoulders.
- Tragic Villain: Despite his ruthless determination to destroy the human race and seize Earth for his own people, Basical is ultimately a victim of circumstance, as it was his generation's selfishness and idleness that led to the destruction of his homeworld and forced him to bring the Baltan children in search of a new home.
- Vader Breath: His roar sounds like that. It's literally the first thing audiences hear right at the start of the film.
- Weather Manipulation: He appears to have this ability in the opening battle in the stratospher, when his electrical attacks clashes against Cosmos' beams, unintentionally summoning a thunderstorm that drenches Musashi, Mari, and their friends which are out camping.
- Well-Intentioned Extremist: Basical never considered that humanity and the Baltans could coexist peacefully, as he believed humanity was doomed to the same fate as his species unless he stopped them.
- Whip It Good: As Neo Baltan, he can create an energy whip from his left hand.
Alien Baltan Shirubyi
- Voiced by: Rina Mogami
For tropes applying to the Baltans in general, see the Ultraman TV Series character sheet
- Invading Refugees: Like all the other Baltan children, she was just a refugee leaving a devastated world for a new one.
- Punny Name: Shirubyi is a play on "Chibi", which describes her design.
- Super-Deformed: Her design is meant to be a chibi version of the original Baltan.
- Super Speed: Although possessing bodies is not a new ability for the Baltans, giving the host super speed is.
- X-Ray Vision: An ability not seen in any other incarnation of Baltan.
A legendary dragon associated with the god of medicine. He was awoken by Basical to grab the attention of humanity, making him the first monster to appear in the series' timeline. Don Ron also appears in Ultraman Cosmos Vs Ultraman Justice: The Final Battle, where he, Lidorias, Golmede, and Bolgils battle some Gloker Pawns attacking Japan.
- All Myths Are True: His existance is supposed to be the stuff of ancient myths, until he awakens from his hibernation. A passing civilian even exclaims that the Dragon exists only in legends.
- Armless Biped: Doesn't stop him from being able to burrow though.
- Breath Weapon: Breathes fire.
- The Bus Came Back: Absent in the series and second movie, but comes back in the third.
- Non-Malicious Monster: Like many kaiju in this series, Don Ron is a peaceful creature that prefers to be left alone. The only reason why it awakens and goes on a rampage is due to Basical taking over its body.
- Our Dragons Are Different: An armless biped associated with the god of medicine and with a head combining the features of Japanese Dragons and Chinese Lions.
- Panthera Awesome: Due to the lion motifs on its head.
- Voiced by: Daisuke Gōri
- Big Bad: Of Ultraman Cosmos 2: The Blue Planet.
- Blade Below the Shoulder: Sandros forms these after he cloaks Earth in darkness in order to slash at the blinded Ultraman Cosmos.
- Breath Weapon: Sandros can open up his jaw three ways in order to spit out a red orb of explosive energy.
- Casting a Shadow: Sandros can produce a black smoke from his body that cloaks the planet in pitch darkness, rendering enemies completely blinded. He also travels through space by cloaking himself in the smoke.
- Evil Sounds Deep: Thanks to being voiced by Daisuke Gōri, Sandros has a low and menacing voice.
- Hand Blast: He can shoot energy blasts from his hand ranging from missile-strength to being able send opponents flying for hundreds of yards.
- It Can Think: While its minions the Scorpis are mindless monsters which only knows of destruction, Sandros on the other hand have some degree of intelligence, capable of communicating and taunting the Ultras in the battle.
- Mind over Matter: Displayed telekinetic abilities.
- Monster Lord: He commands the Scorpis.
- Omnicidal Maniac: Sandros seeks to reduce the entire universe to nothing more than a lifeless wasteland of endless deserts.
- Red Eyes, Take Warning: Has two red eyes that are among the few things visible in his darkness during the battle with Cosmos.
- Social Darwinist: Espouses his philosophy when he first meets Cosmos.Sandros: The strong will destroy the weak, that is a universal rule!
- Walking Wasteland: Sandros' black smoke that disintegrates non-organic material in a similar manner to the Scorpis' withering orbs.
- Villainous Legacy: Dead by the third movie but his action weighs heavily on Justice because he didn't kill him 2,000 years ago when he had a chance out of mercy. Making him willing to join the Delaxion in destroying the earth when the earth is seen as a threat like Sandros.
Sandros' minions, the Scorpis are alien kaiju that travel across the universe with the sole purpose of transforming any planet they encounter into a lifeless desert under the bidding of their master.
- Beware My Stinger Tail: They possess long pincer-tipped tails they use to wound opponents in battle.
- Breath Weapon: The Scorpis breathe a red beam of energy that instantly withers and disintegrates whatever it hits.

- Walking Wasteland: Like Sandros, the Scorpis leave only blasted ruins behind on any planet they visit.
Alien Gyashi Jin and Shau
- Played by: Mai Saito (Shau), Masatoshi Matsuo (Jin)
- Anti-Hero: Jin, who was very distrusting of humans to Fantastic Racism levels, despite also opposing Sandros and the Scorpis like Musashi and SRC were. He does eventually realize his misguidedness though.
- Hand Blast: Both Jin and Shau were able to fire energy bolts from their fingers. These bolts can do a variety of things, but Jin mainly used them to try kill humans.
- Human Aliens: Unlike humans though, they're primarily an aquatic race. Shau is actually seen transforming into a mermaid a few times, so it's possible that was her true form.
- Our Mermaids Are Different: As mentioned earlier, Shau can turn her legs into a fish's tail at will. Musashi actually mistakes her for one when he first spots her, and considering her species' association with the ocean, it could be said that they're essentially alien merpeople.
- Red Oni, Blue Oni: The humorless and skeptical Jin is the blue to the more sympathetic and cheery Shau's red.
A species of stingray-like kaiju that dwells in the oceans around Saipan Island. They befriend Jin and Shau, gaining the ability to merge with them in order to battle the Scorpis.
- Breath Weapon: They breathe explosive orbs of red energy.
- Flying Seafood Special: Is based on manta rays.
- Fusion Dance: Jin and Shau can call forth a Reija and merge with them, gaining control over the monster and giving it legs to move on land and arms to battle enemies.
- Gentle Giant: Reija are completely peaceful monsters that eagerly assist the humans and Gyashi against the forces of Sandros and his Scorpis.
- Giant Flyer: The Reija can fly in both normal form and limbed form.
- If It Swims, It Flies: Is an aquatic monster with flight abilities.
- Sea Monster: Based on stingrays.
- Portrayed by: Osamu Ryutani (voice of Ultraman Justice), Kazue Fukiishi (as Julie)
- Above Good and Evil: An extremely rare Ultraman example. Ultraman Justice is better described as a protector of order rather than of a warrior for goodness, willing to battle both villains like Sandros and heroes like Cosmos if they pose a threat to peace of a universal scale. However, he does eventually learn the importance of protecting life.
- Aloof Dark-Haired Girl: His human form.
- Anti-Hero: In contrast to the more messianic Cosmos and most obviously shown in the third movie.
- Bash Brothers: With Ultraman Cosmos. Helps that both of Justice's modes have at least one combination attack with Cosmos. They might actually be literal 'brothers' in a sense, as they're confirmed to be two halves of Ultraman Legend.
- Character Development: In the third movie, Justice spends from The Stoic enforcer of Delaxion to finally understanding what it means to protect.
- Comfort Food: Seems to enjoy eating the sweets that he received from a human girl.
- Easily Forgiven: Kills Cosmos at the early of the third movie, but when said Ultra revived, the first thing he did is replenishing Justice's energy. Even the red Ultra was astonished at his forgiveness.
- Expy: To Ultraman Agul's human host, whose racism towards humanity stems from the influence of a great cosmic entity. Yet the two eventually joined the titular Ultraman in facing said antagonist.
- Foil: Whereas Ultraman Cosmos is a Friend to All Living Things who values life above all else, Justice is more likely to kill his enemies, and also care not for life — he destroys anyone who disrupts cosmic peace regardless of whether they are good or evil.
- Gender Bender: The only male Ultra to have a female human identity. This is because he views justice as above gender, so he doesn't consider what gender he appears as to be important.
- Hero of Another Story: Is the true main character of Ultraman Cosmos vs. Ultraman Justice: The Final Battle.
- In a Single Bound: Julie can do this quite easily during a fight against several thugs.
- Informed Ability: His Standard Mode has lots of it.
- It's All My Fault: He spares Sandros for 2,000 years back when he was harmless, only for the monster to become what he is today. He is still affected by this mistake.
- Kick Chick: Subverted that it was his female human form, but nonetheless managed to do so by moping the floor against several thugs at night.
- Literal Split Personality: It's alluded to through All There in the Manual and eventually confirmed in Ultra Galaxy Fight: The Absolute Conspiracy that Justice is actually the result of Ultraman Legend splitting in two to become him and Cosmos.
- Multiform Balance: Like Cosmos, although he has less forms.
- Redemption Promotion: His understanding of true justice and determination to stop Delaxion's forces allows him to gain Crusher Mode.
- Telepathy: Julie's Establishing Character Moment has her communicating with Musashi.
- Took a Level in Kindness: As noted above, Justice begins as an Anti-Hero interested only in protecting the cosmic order, but his interactions with Cosmos and humanity led him to realize the importance of protecting life.
By the time of the third film, the original members of EYES have been transferred to different branches of SRC, leaving Fubuki as the captain of a new team in the battle against Delaxion and its forces. This new team is made of Eiichi Kashima, Natsuki Kuramoto, Kazuomi Watarai, and Ryojiro Shiyoda.
- Voiced by: Chisako Hara
- Anthropomorphic Personification: Of universal law.
- Anti-Villain / Hero Antagonist: She's somewhere between both, as although she serves as the movie's Big Bad, her causes are just (if lacking in empathy for living beings). She was responsible for sending Justice to destroy Sandros in the previous movie, but ultimately she cares more about universal order than good and evil.
- Big Bad: Of Ultraman Cosmos vs. Ultraman Justice: The Final Battle.
- Energy Being: She is essentially a gigantic white orb of light surrounded by an almighty aura.
- Well-Intentioned Extremist: She prophesied that the inhabitants of Earth (humans, animals, and monsters) would become cosmic threats in the future. So while she does have a justification for her sending her Glokers and Ultraman Justice, she ultimately failed to realize their potential for goodness, to make themselves better, and the fact that many of them really just want to live their lives in peace.
An immense and all-powerful superweapon robot created by Delaxion to annihilate all life on Earth.
- Mook Maker: The Gloker Mothers come from its hold.
- Names to Run Away from Really Fast: It's a gigantic superweapon designed to end life on Earth.
- Shock and Awe: Can fire powerful lightning bolts as a defense mechanism.
- Spell My Name with an "S": Also known as Giga Ender.
- Wave-Motion Gun: Given that its purpose is to raze planets of life, it's equipped with one so powerful that it almost killed Cosmos.
- Weapon of Mass Destruction: It's a gigantic and nigh-invincible robotic superweapon able to fire a beam from its core that can annihilate every living creature on a planet in a single shot.
The robotic legions of Delaxion spawned from the Gloker Mother to prevent Earth's inhabitants from opposing Delaxion and Giga Endra. Multiple Gloker Pawns are able to merge into a single Gloker Rook.

- Fusion Dance: Multiple Gloker Pawns reassemble their structures to merge together as a Gloker Rook.
- Blade Below the Shoulder: The Glokwer Pawns' laser wrist cannons are replaced with wrist blades.
- Elite Mook: Only one Gloker Rook appears, when a squad of Gloker Pawns get overwhelmed by the attack of Lidorias, Golmede, Bolgils, and Don Ron and determine the best course of action is to become something that would defeat all four monsters.
- Humongous Mecha: Giant robots created by a cosmic entity as footsoldiers to enforce its order upon Earth.
- Mecha-Mooks: As the title of "Pawn" indicates, they serve as Delaxion's footsoldiers produced from the Gloker Mothers en masse.
A spaceship that spawns Gloker Pawns, but is able to transform into the formidable Gloker Bishop robot if needed.
- The Juggernaut: These things are damn nigh-invulnerable in both spaceship and robot form!
- Mook Maker: Gloker Mothers produce the Gloker Pawns to attack Earth.
- Transforming Mecha: A Gloker Mother can transform into a Gloker Bishop.
- Cyber Cyclops: Like the Gloker Pawns, they have a single red eye.
- Elite Mook: Even moreso than the Gloker Rooks, as Delaxion only calls them forth when Ultraman Justice decides to join Cosmos in protecting Earth from Giga Endra.
- Hand Blast: The Gloker Bishop fires powerful orbs of explosive energy from its hands.
- Madness Mantra: The Gloker Bishop constantly says "Remove All Obstacles!"
