Kazuki Komon

Portrayed by: Takuji Kawakubo

"The reality one sees...if it were all a deception..."

The main character of the series. Komon is a kind-hearted, straightforward person who is always willing to help others. Throughout the series he bonds with the Deunamists and grows alongside them. This culminates in him becoming the fifth and final Deunamist, host to the true form of Nexus: Ultraman Noa.
  • 10-Minute Retirement: In episode 16, he leaves the Night Raiders but returns at the end of the episode.
  • Adorkable: Komon is a Nice Guy, but rather straight-laced. Also, there is his reaction when he gets tomato ketchup on his nose during a dinner in episode 30.
  • Alliterative Name: Kaizuki Komon.
  • Armor-Piercing Slap: Komon gets one from Nagi in episode 13. She was trying to snap him out of his grief for Riko's demise.
  • Bad Liar: This is a given, as Komon is a naturally straightforward person. He lied to Ren's boss that he was Ren's cousin, something that Ren joked about upon hearing about it. Even Ren's co-worker remarked on how Komon used honorifics when referring to his 'uncle and aunt'.
  • The Big Damn Kiss: Shares one with Riko in episode 10. Then, she dies 2 episodes later.
  • Catapult Nightmare: Has one in episode 7 where Nagi shot him.
  • Dark and Troubled Past: When he was a child he almost drowned. In episode 1, he is terrified and loses control of himself during a rescue operation taking place near a river.
  • Friend to All Children: Komon goes out of his way to rescue a girl trapped in a factory with her dog in episode 7. He meets up with her in episode 8 and proceeds to have a chat with her, but the Memory Police had already erased the girl's memory.
  • The Hero: Despite not being a Dunamist at first.
  • Heroic B.S.O.D.: Goes through one as a result as a result of Riko's death in episode 12. It is only in episode 16 when he gets back to his normal self.
  • Inner Monologue: As the main character, he has plenty of these.
  • Instant Sedation: When he wakes up in the middle of his physical examination in episode 1, he is quickly sedated before he can ask more questions.
  • It's All My Fault: For a while, he believed that Riko's death and a family being attacked by Nosferu in episode 12 happened because they cross paths with him.
  • Lotus-Eater Machine: Mizorogi conjures up an illusion of the late Riko, making Komon think that he can reunite with her.
  • Masculine Girl, Feminine Boy: Feminine Boy to Nagi's Masculine Girl.
  • The Medic: Komon used to be in a rescue team, so he was able to patch up an injured Ren in episode 27.
  • Naïve Newcomer: At first, because he is new to the fact that TLT and Space Beasts exist.
  • New Meat: Night Raiders' newest member. The start of the series highlights his unfamiliarity with the ways of the Night Raiders and TLT.
  • Nice Guy: Easily the best example in the show. He's straightforward, always willing to help others, bears no ill will towards anyone and is also quite empathetic.
  • Parental Abandonment: His girlfriend Riko's family is shown a few times, but there is hardly any mention about Komon's parents. However, he was shown on the phone with his mother in episode 13 and she seemed to care about him.
  • The Power of Hate: Nagi tries to get him to cultivate this. On the other hand, Himeya wants Komon not to give in to his hatred.
  • Say My Name:
    Komon: Riko!
  • Sensitive Guy and Manly Man: From his dialogue with Himeya in episode 15, he sees himself as the Sensitive Guy to Himeya's Manly Man.
    Komon: I'm not a strong man like you.
  • Strapped to an Operating Table: In episode 1, when TLT perfoms a physical examination on him. When he wakes up in the middle of it, he is understandably upset and confused at the situation.
  • Supporting Protagonist: Played straight, making Nexus the first show in the Ultra Series to use this trope. The story is told mainly from Komon's point of view, even though he is not a Deunamist (in other words, he does not transform into the titular hero) at first.
    • He loses his role as this when he eventually becomes the fifth Deunamist in the final episode.
  • The Lost Lenore: His girlfriend, Riko. The fact that she was Dead All Along and was actually Dark Faust shook Komon considerably. Took him quite a while to get over that.
  • This Is Unforgivable!:
    • He is visibly angry with the Memory Police for erasing the memory of a girl he rescued in episode 8. The MP leader showed him why it was needed, which gave him second thoughts.
    • This is clearly on his mind when Mizorogi taunts him about making Riko his People Puppet in episode 13.
    • In episode 25, he says it out loud to Mizorogi after witnessing a defeated Ultraman.
  • The Watson: Justified, as he is new to the Night Raiders and TLT.
  • Wrong Genre Savvy: As a character, Komon would fit nicely in a typical Ultra Series, something which Nexus is not.
    • He is fortunate enough to be the first person to encounter Ultraman. After being saved by him in episode 1, he firmly believes that Ultraman is on the side of good and is upset when the other Night Raiders, especially Nagi do not support his belief.
    • In episode 3, he is surprised when Nagi revealed to him that Space Beasts attacks are covered up and that the victims' families do not know the truth of what really happened to their loved ones who are killed by Space Beasts.
    • In episode 8, he is happy to meet up with a girl he rescued during an operation. He expected her to recognize him and to name her dog with the name his suggested, much like how a typical Ultra Series episode with a Victim of the Week would end. Instead, he finds that her memory has been erased.

Nagi Saijyo

Portrayed by: Yasue Sato

The deputy leader of the Night Raiders. She is very strict, especially to Komon and can be quite brutal in certain situations. She is driven to fight by her hate of Space Beasts, stemming from incidents regarding her childhood and her former lover Shinya Mizorogi.

  • Anti-Hero

  • Commander Contrarian: Stubbornly refused to entertain the idea that Ultraman is not evil.
  • The Cynic: Even though she has seen Ultraman destroy many Space Beasts, she explicitly express her distrust against them. This is one reason why she does not get along well with Komon.
  • Dark and Troubled Past: The murder of her parents and seeing her former lover go to the dark side.
  • Determinator: In her crusade against the Space Beasts.
  • Empowered Badass Normal: After inheriting the Light.
  • Fatal Flaw: Wrath. Dark Zagi made sure she'd develop this. Her hatred towards him and his creations is exactly what allows him to return to full strength.
  • Fantastic Racism: Her mother's death at the hands of an inhuman being led her to have a seething hatred of the Space Beasts and anything inhuman in general.

  • Masculine Girl, Feminine Boy: Masculine Girl to Komon's Feminine Boy.
  • Parental Abandonment
  • The Power of Hate: Her immense hatred of Space Beasts is what drives her to take her job as a Night Raider very seriously. Revealed to have been invoked by Dark Zagi so that she would become a Deunamist.
  • Selective Obliviousness: She is steadfast in her belief that Jun Himeya / Ultraman is an enemy, even though there is evidence to the contrary.
  • The Smurfette Principle: Averted, as there is also Shiori Hiraki. Played straight in flashbacks, where she was the only woman in the team, the others being Captain Wakura, Ishibori and Deputy Captain Mizorogi.
  • Sour Outside, Sad Inside
  • This Is Unforgivable!: It's on her mind when it comes to the individual who murdered her mother.
  • Tomboy and Girly Girl: Nagi is the tomboy, Shiori is the girly girl.
  • Took a Level in Cynic: She was already distrusting of inhuman beings. Her former lover Mizorogi added fuel to the fire.

  • Tritagonist: After Komon and the Deunamists.
  • Missing Mom: When she was young, her mother was killed by a being resembling The One.

  • Revenge: For her mother. It is also what drives her to be a ruthless Night Raider.
  • Unfriendly Fire: Shoots at Ultraman upon her first time seeing him in episode 3.
  • Unwitting Pawn: Revealed to have been one to Dark Zagi all along.
  • You Killed My Mother:Is utterly furious at the space beasts and Dark Zagi in particular.

Instead of being a protector, he chose to slaughter them in droves to the point they blew up their own planet to be rid of him. This failed, and he created an army of Space Beasts to conquer the galaxy.

    Space Beasts 

The various monsters that Nexus and Night Raiders battle throughout the series.

The One

First Appearance: Ultraman: The Next


First Appearance: Night Raid
Slug-like Space Beasts attracted to ethanol, a small population of Pedoleons hid out in the woods eating people and doing their best to avoid Night Raider notice. Komon was nearly eaten by one before Nexus crushed it under his gigantic fist. Later, the Pedoleons began to change tactics when they realized that Night Raiders was interested in human safety. They merged into giant form and held some humans hostage. Nexus returned and would have killed the Space Beast if Nagi hadn't attacked him. Later, the Pedoleons merged again when Night Raiders attempted to lure them into a trap, but this time Nexus destroyed the Space Beasts in his Meta-Field.
  • Asteroids Monster: Played straight and reversed as Pedoleon is a mass of small monsters that can split and merge into giant form as needed.
  • Blob Monster: A slug-like creature capable of turning into liquid and merging into a kaiju form.
  • Combat Tentacles: In giant form.
  • Expy: As a Blob Monster that feeds on ethanol, has a flight form, and can split, the similarities to Hedorah are not hard to notice.
  • Gratuitous German: In each form, its name is Pedoleon ___ with a German word fitting the form. "Kleine" in its base form, "Groß" when kaiju-sized, and "Fliegen" in flight form.
  • It Can Think: When Night Raiders begins to hunt down the Pedoleons, they discover that the monsters are changing tactics to gain an advantage over Night Raiders, including holding humans hostage and merging themselves into giant form.
  • Overly Long Tongue: Used for snatching unlucky humans and eating them in its small form.
  • Starter Villain: For Komon, as it's the first Space Beast he encounters.


First Appearance: Dunamist
Bugbuzun was an insectoid Space Beast that lived in the Japanese countryside, eating people. Himeya encountered the monster and battled it as Nexus. Night Raiders arrived and attacked both giants, allowing Bugbuzun to wound Nexus and escape underground. Bugbuzun proceeded to start eating people again, but Night Raiders drew it above ground and killed it with Freezer Shots and a well-aimed explosive round.
  • Beware My Stinger Tail: Has a large pincer on its tail.
  • Big Creepy-Crawlies: Resembles an oversized mix of a locust, a cockroach, and a cicada.
  • Combat Tentacles: When it burrowed underground, it would use tentacles to snatch victims from below.
  • Giant Flyer: It's first appearance, where it snatches cars straight out of desolate highways.
  • Tunnel King: After escaping the Night Raiders the first time, it spends the rest of its story arc underground.


First Appearance: Relic
Shortly after Himeya encountered Nexus, Galberos came to Earth and became Himeya's first opponent in his career as Ultraman. Although defeated, Galberos returned later under Dark Mephisto, using its illusion abilities to confuse Night Raiders. Nexus fought the three-headed Space Beast and Night Raiders gave support, but Galberos tricked the team into harming Nexus, allowing it and Mephisto to escape. Then, Mephisto came back with Galberos when he trapped Night Raiders and Nexus in his Dark Field. Nexus killed Galberos and Mephisto fled. However, Unknown Hand revived Galberos again to assist Mega Flash. Nexus killed the wolf-like Space Beast once more.

Arguably the most iconic Space Beast, Galberos has reappeared many more times in the franchise. It is often under control of a sinister alien too, just like in its original appearances.


First Appearance: Warning
A flower-like Space Beast, Rafleya terrorized humans with its incinerating pollen. Night Raiders came to assist Nexus against the monster and its master Dark Faust. However, they realized that killing Rafleya would create a deadly combustion from its pollen, so Nexus was left to handle it. Rafleya escaped with its master though. Later when Nexus was fighting Faust and Rafleya again, Night Raiders entered the Meta-Field and helped even the odds for the silver hero. Rafleya was destroyed in a fiery burst, but Nexus saved Night Raiders from potential incineration.


First Appearance: Marionette
A horrible rodent Space Beast, Nosferu had killed Riko and her family many years ago. Faust revived Riko and took her body for a host, but her time with Komon was starting to weaken Faust's power over her. Soon when, Nexus battled Faust and Nosferu, the Space Beast attempted to kill Komon, but Riko, now in full control of Faust, sacrificed herself. Nexus destroyed Nosferu, but it soon regenerated and attacked a happy family, killing the parents and reviving them as minions to feed their former children to it. It managed to imprison the young daughter (also named Riko) in its head and Nexus refused to kill it for fear of the loss of human life. Night Raiders, unaware, did the blow, injuring the girl. Nosferu regenerated again and attacked Night Raiders. It escaped when Komon lost the courage to kill it and soon grew back to its full size. This time, Night Raiders knew its weakness and Nexus helped them out. They destroyed its regenerative organ and Nexus destroyed the horrid Space Beast permanently. Nosferu has the notable of honor of being the Space Beast to appear in the most episodes at 6 in a row.


First Appearance: Apocalypse
Smaller than most other Space Beasts, 2 Arakunias attacked workers at a factory and Night Raiders headed in. Mizorogi and Nagi killed both creatures. Arakunia also appeared in a Bonus Episode where one attacks Shiori, but she is saved by Night Raiders and soon recruited.


First Appearance: Apocalypse
A "small" amphibian-like Space Beast, a single Frogos was in the same factory as the 2 Arakunias. Nagi killed the monster with a slew of shots. Despite Frogos' extremely minor appearance, it has reappeared several more times in the franchise (all of them just as brief). However, it received a size boost to match it up with standard Ultra monsters.
  • Breath Weapon: Green fireballs.
  • We Hardly Knew Ye: Only appeared very briefly in a flashback in Nexus. His reappearance in Ultra Galaxy Mega Monster Battle was equally brief.
  • Your Size May Vary: In Mega Monster Battle, Frogos' sized is boosted from 10 meters to 40 meters. Justified as the majority of Ultra monsters are around that size or larger, so the producers needed to equal the odds for Frogos.


First Appearance: Cross Phase Trap
The rocky Space Beast known as Golgolem ate people in the Japanese mountains, catching Night Raiders attention. The problem was it was able to phase through various sub-spaces and Nexus, injured from his battle with Galberos, was unable to stop the monster. When Golgolem began to take interest in a nearby town, Night Raiders set up a trap that would disable its phasing powers. It worked, but the presence of some journalists photographing the monster forced Night Raiders to change tactics. Nexus came in, and although he destroyed Golgolem's Nested Mouths, it fled. Night Raiders used the time to create a plane with Golgolem's phasing abilities. They drew it out and Nexus fought it. He killed the monster, but the hero was no longer fit to fight anymore.


First Appearance: Cure
The vile Space Beast Kutuura was used by Dark Mephisto to attract the attentions of the Night Raiders and the wounded Nexus. It opened up portals to its home, the Land of the Dead, at six specific locations to form a code which the Night Raiders cracked. Nexus entered the portals and battled the horrid monster. However, Kutuura overpowered the weakened hero, but the Night Raiders entered the scene, annihilating the lord of the Land of the Dead with their new weapon - the Ultimate Vanisher.


First Appearance: Prophecy
Sort of a mix of a crab and a scorpion, the Space Beast Grantella rampaged in the Japanese countryside. Night Raiders entered to battle and were surprised to see Nexus alive and well. The hero had been reborn with a new host - Ren Senjyu! Nexus fought the monster in his Meta-Field, but before he could kill it, Unknown Hand took Grantella to safety. Later, Night Raiders discovered Grantella had been conserving its true strength to study the new Nexus and the Space Beast returned, now with the full extent of its power. Nexus still managed to slay the monster though.


First Appearance: Calling
A horrible spider-like Space Beast, Banpira made a life in the mountains, striking hikers and campers from the safety of its fog and making sure survivors were without memory of its attacks. Night Raiders suspected right though when they believed a Space Beast was behind the amnesiac attacks and managed to clear out its fog. Nexus came in and Night Raiders assisted it. However, Banpira got away, but not before its fog-generating organ was destroyed. Changing tactics, Banpira marched for civilization, but Nexus came back and trapped it in the Meta-Field, killing the spider monster in it. Banpira has reappeared several more times outside of Nexus.

Lizarias/Lizarias Golar

First Appearance: The Watcher
The saurian Space Beast Lizarias terrorized the Japanese countryside until Nexus came and blew the monster to pieces. However, the cleanup crew failed to notice a single scale, and soon Lizarias Golar was born from it! Lizarias Golar was soon attacked by Nexus and Night Raiders. When the Meta-Field came down on it, Unknown Hand turned it into a Dark Field and Lizarias began to overpower Nexus. However, Night Raiders and Nexus managed to kill the monster.

Mega Flash

First Appearance: A.D. 2004
The flying Space Beast Mega Flash first appeared over an urban region and it began to cause chaos. Ren was forced to transform into Nexus in front of the whole world and Night Raiders came in. However, Unknown Hand called Mega Flash away. Later Mega Flash returned again and Nexus fought it in the eyes of thousands. Mega Flash escaped underground, but soon burst back out. This time assisted by a revived Galberos, Mega Flash put up a difficult battle for both Nexus and Night Raiders. However, Mega Flash was destroyed by Night Raiders. Galberos followed its ally into death suite.


First Appearance: Farewell
Out of monsters, Unknown Hand unleashed all the deceased Space Beasts in the form of a monstrous chimera named Izmael. Izmael rampaged through the city and Ren, on the brink of death, became Nexus once more. The Night Raiders helped out, but it took more than everything the forces of good had to slay the ultimate Space Beast. By the time the battle was over, the light was to be passed down again.

Bugbuzun Golar and Bugbuzun Brood

First Appearance: Ultraman Nexus EX
A more powerful variant of the original Bugbuzun, Bugbuzun Golar spawned dozens of Bugbuzun Broods to eat humans and in turn be eaten for what the Broods gained from their hunts. Night Raiders was unable to detect the Broods due to their modified Space Beast signals. However, one Brood made the mistake of attacking Night Raiders. As Night Raiders hunted them down, Ren encountered a Brood and it was transformed into a giant by Unknown Hand. Nexus was summoned and the two fought in the Meta-Field. Nexus killed it easily while Night Raiders managed to injure another one's face, altering the Space Beast signal and finally letting them find the Golar. The Golar burst from the earth and attacked Night Raiders. Ren called forth Nexus and killed the monster.

The Bugbuzun Broods made a surprise return in the Ultraman X episode "Bond Unite", a Homage to Ultraman Nexus celebrating the 10th anniversary of the series' end, featuring a guest appearance from Nexus as well as re-explorations of the show's themes and concepts. They even invited Nexus' director to produce the episode! Oddly, Bugbuzun Golar is never referenced in any way.
  • Big Creepy-Crawlies: As per the original Bugbuzun.
  • Breath Weapon: The Broods breathe confusion gas.
  • Combat Tentacles: Used by the Golar in the same way as the normal Bugbuzun.
  • Make My Monster Grow: The human-sized Bugbuzun Brood always gets turned giant-sized whenever it appears.
  • Mook Maker: Bugbuzun Golar creates Bugbuzun Broods to search for human prey. The Broods eat the humans and go back to their mother who eats them! Frighteningly, only the Bugbuzun Broods are seen when they return in Ultraman X, suggesting the Golar is still out there...
  • Tunnel King: The Golar hides underground while the Broods do the dirty work.
