As a whole:
- Badass Crew: Competent enough to take out the Space Beasts by themselves and fully support Nexus when he shows up.
Portrayed by: Takuji Kawakubo
- "The reality one sees...if it were all a deception..."
- 10-Minute Retirement: In episode 16, he leaves the Night Raiders but returns at the end of the episode.
- 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 BSoD: 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.
Portrayed by: Yasue Sato

- Determinator: In her crusade against the Space Beasts.
- Empowered Badass Normal: After inheriting the role of Ultraman Nexus' host.

- 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: While harsh and unfriendly, her attitude and actions are the result of her traumatic childhood and the loss of her loved ones at the hands of Space Beasts.
- 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.

- Tritagonist: After Komon and the Deunamists.
- Revenge: For her mother. It is also what drives her to be a ruthless Night Raider.

- The Captain: Of the Night Raiders.
- Reasonable Authority Figure: He's probably the most supportive member of the team towards Komon.

- The Smart Guy: His role in the Night Raiders is to set up tactics and work out strategies and the like on his computer.

- The Lost Lenore: Having lost his wife during the events of 2004, he seeks to understand more about the Light, Nexus, and the Dunamists in order to defeat the Space Beasts.

- Stoic Spectacles: He is usually quite calm, composed, and bespectacled.

Portrayed by: Tetsuya Bessho
The first Deunamist. Maki is the protagonist of Ultraman: The Next. He is a pilot in the Japanese Air Force, with a wife named Yoko and a son named Tsugumu who suffers from a congenital blood disease. He merged Ultraman the Next (the initial form of Nexus) when he collided with the Ultra's travel sphere as the hero was pursuing after the One.
- Family Man: His devotion to his wife and child are among his major traits, and have not been seen in other human hosts until the introduction of Leito Igaguri in Ultraman Geed.
Portrayed by: Yusuke Kirishima
The second Deunamist. A serious, brooding individual not given to trusting institutions, Himeya was a photojournalist, specializing in war photos. During an assignment in Southeast Asia, he befriended an orphan named Sera, who was unfortunately killed in the conflict — something that deeply haunts him to this day.
- Arch-Enemy: Dark Faust and later Dark Mephisto.
- Being Good Sucks: He risks his life to fight the Space Beasts, but TLT (except Komon) does not trust him and the general public is unaware of his heroic deeds. In episode 21, he is taken against his will by TLT as an experimental subject.

- Camera Fiend: When he worked as a photojournalist.

- Intergenerational Friendship: Forms one with Sera, a young girl who lost her family in the war and treated him when he was injured. He became a big brother figure to her.
- Irony: As noted by Sakuta, the war photos Himeya took earned international acclaim. Himeya was even nominated for a dream award overseas, but he was probably too psychologically scarred to appreciate all that.
- Leave Me Alone!: To his former colleagues, Negoro and Sakuta.
- Limited Wardrobe: He always going from place to place in the same black jacket and green shirt. Justified as he is currently unemployed and if his current living quarters environment is anything to go by.
- Offscreen Teleportation: Particularly noticeable in the first few episodes.
- Parental Substitute: For Sera, Himeya became a big brother figure.
- Past Experience Nightmare: Part of being a Shell-Shocked Veteran, he constantly suffers from nightmares where he witnesses Sera's death again and again.

The third Deunamist. Outwardly, cheerful, and optimistic, Ren is a human created through genetic engineering under the flag of the Prometheus Project. However, Ren ran away from his creators after a discovering a terrible secret about his creation, and now he works at an amusement park, seeking to bring smiles to the faces of every visitor.
- Artificial Human: A 'child' of the Prometheus Project.
- Broken Hero: At first glance, would anyone think that this cheerful, carefree young man was actually a runaway test subject who does not have long to live?
- Dramatic Drop: Drops and breaks a cup when Mizuo mentions the word 'Raphael' to him in episode 30.
- Foil: To Jun. A cheery, energetic young man to Jun's own stoic, quietly miserable exterior.
- For Happiness: His ultimate goal is to make as many people happy before his inevitable premature death.
- Friend to All Children: A distinctive trait.
- Good Is Not Soft: He may be far cheerier than Himeya, but Ren is every bit as competent of a human host as him and determined to battle the Space Beasts.
- Keet: Can be rather hyperactive at times.
- Love at First Sight: With Mizuo.
- Nice Guy: In contrast to the more cynical Himeya, Ren is on good terms with almost everybody and greatly lightens up the series as well.
- Stepford Smiler: Underneath his desire to make as many people happy as he can is a deep sadness that his death is the result of a falw in his creation.
- Your Days Are Numbered: A genetic imbalance in his DNA cuts his lifespan to only 17-18 years. A drug called 'Raphael' is his only hope of survival.
Ultraman Nexus/Ultraman the Next/Ultraman Noa
A being of light from space, while on Earth he lends his powers to the Deunamists to face the Space Beasts. He is the same Ultraman from Ultraman: The Next, and unique in that he hops from host to host multiple times throughout his series. He came to Earth while chasing the One (as Ultraman the Next), and stays here in the hope of finding the one behind the Space Beast attacks. He has since made several appearances in much more kid-friendly Ultra Series material alongside other Ultra heroes.
- Adaptive Ability: As noticed by Illustrator in episode 5, Ultraman Nexus' ability is to adapt his body to his surroundings and grow stronger from each battle. In fact, after his battle as The Next, Ultraman Nexus is the former's adapted form to better suit with the Earth atmosphere. His multiform balance also embodied the trope, as he started as Anphans but later on becomes Junis and the Junis Blue is a variation of the former. Coupled with his constant bond with different Deunamist over the series' run, he eventually regained his long lost form, Noa.
- Brought Down to Badass: Ultraman the Next is actually a weaker form of Nexus, who is in turn a weaker form of Noa, due to him losing most of his power when trying to stop the One from reaching Earth.
- The Chooser of The One: Due to the fact that Nexus changes between human hosts, allowing him to decide which human is most worthy of holding the Evolthruster.
- Contrasting Sequel Main Character: Made explicitly to be everything Ultraman Cosmos was not.
- Finishing Move: Unique in that which one he uses depends on which host he has.
- In every form, his Anphans form uses the Cross-Ray Storm, your classic "+"-styled Hand Blast used by most Ultras.
- His Junis form uses the Over-Ray Storm, which is an "L"-shaped version of the Cross-Ray Storm, similar to some Ultras.
- Junis Blue has the Arrow-Ray Storm, which allows him to create a giant bow of energy with his right arm that fires a cutting blade of light.
- Godzilla Threshold: Nexus' true power is Core Final, which has his Energy Core on the chest releasing a burst of energy. This is only used during emergency occasions and so far, each Dunamists used it once with varying effect:
- Himeya used it to partially revive Nexus from the dead.
- Komon used it in a director's cut of episode 31 to escape Banpira's strong webbing, releasing a stream of energy ray from his chest.
- Komon used it in final episode to shuffle every available forms of Nexus up to that point before regaining his lost form, Ultraman Noa.
- Hand Blast: Asides from his Finishing Moves, Nexus can toss out small bolts of light called Particle Feathers.
- Heart Is an Awesome Power: As narrated by Sera in episode 24, Nexus fights by choosing his Deunamists, whose desire to protect others becomes the source of his power. The official website proclaims that Nexus operates in the concept of bonds, but the constant meddling of TLT in filtering the information of Ultraman and Space Beast in the public severely drains him from his strength.
- Meaningful Name: Anphans is a mutation of "enfance", the French word for "childhood", while Junis is from "jeunesse", or "youth". And Ultraman Noa is named after the Noah of the Bible.
- Multiform Balance: Like many Heisei Ultras, Nexus is able to shift modes, but unlike most, his alternative forms are based on his current human host.
- Jack-of-All-Stats: Anphans, the default form of Nexus, which is gray.
- Lightning Bruiser: Junis, the form used by Jun Himeya. It's the traditional red color of almost all Ultramen.
- Fragile Speedster: Junis Blue, the form used by Ren Senjyu. It's blue, like Cosmos.
- Super Mode: Ultraman Noa, his true form. The most powerful Ultra in the franchise, behind Ultraman King. The only reason why the series even began in the first place is because Nexus lost that form when battling the One.
- Mysterious Past: He's something of a legend, even amongst other Ultramen, as he was an Ultraman before the other Ultras even existed. Rumor has it he was birthed from a supernova.
- Non-Standard Character Design: Due to the fact that Nexus was at first meant to be a complete reimagining of the original Ultraman, his design drastically differs from any Ultra before or after.
- Physical God: His true form Ultraman Noa is one of only two Ultras to be classified a god, the other being Ultraman King.
- Phantom Zone: The Meta Field, a subspace created by Nexus to fight the Space Beasts without risk of civilian casualties or of being discovered. It puts considerable stress on the user's body after three minutes of continuous use.
- Time Abyss: The oldest Ultra in existence at over 350 thousand years old.
- Unwitting Pawn: Alongside Nagi, Nexus silently becomes this to Ishibori in order to revive Dark Zagi to glory. His bonding with Deunamist and constant battles with Space Beast/Dark Giants was to empower him before Nagi becomes his latest host and for Ishibori to harvest Nexus' powers.

Hiroyuki Misawa / Dark Mephisto Zwei
Portrayed by: Yoshito Takeuchi (live)
An officer for the Memory Police who fell under the influence of Unknown Hand. The enigmatic entity turned him into a clone of Dark Mephisto, sending out the corrupted man to kill and replace Mizorogi after he is arrested by TLT during the Banpira incident.
- Evil Counterpart: He's already a copy of the original Mephisto, but his possession of several new powers and demonstrate the ability to be faster makes him a match of Nexus Junis Blue, the red Junis' evolution. Whereas Senjyu has several days to live, his host's first transformation is also his last before dying from defeated.
- Evil Doppelgänger: Of Dark Mephisto. They are essentially the same, only Zwei is far worse.
- Red Eyes, Take Warning Zwei's sole physical difference from the original Dark Mephisto.
- Superior Successor: Is even stronger than the original Mephisto, with the exact same attacks.
- We Hardly Knew Ye: Only lasts for one episode.
The true mastermind behind everything in the series, under the alias Unknown Hand. An evil clone of Ultraman Noa, created by the Visitors to be their own counterpart to Noa. 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 assembled an army of Space Beasts to conquer the galaxy.
- Big Bad: Whether only a presence or as the Unknown Hand, he is the true mastermind and ultimate evil behind all the events of the series.
- Demonic Possession: If he didn't outright kill Ishibori when he took him over, it was this.
- Evil Counterpart: To Ultraman Noa. The extracanonical sources elaborate on this even further by giving them mirroring attacks.
- Evil Knockoff: Notably not made this way, just chose this.
- Gone Mad From The Revelation: He was created to defend his creators from the Space Beast attacks. Unfortunately he becomes rogue after discovering his true nature as an impostor to Ultraman Noa. The 2016 novel Ultraman F played this further just by revealing Noa's name triggers his Berserk Button.
- Greater-Scope Villain: He orchestrated all the Space Beast attacks, from The One to Izmael.
- Healing Hands: His Dark Field G already heals any Space Beasts back to health, but extracanonical magazines confirm direct healing with his hand as part of his abilities. In the 2016 novel Ultraman F, he did this to his Dark Giants.
- Kill and Replace: What he did to Hajime Yamaoka, or as Night Raiders know him as: Mitsuhiko Ishibori
- Monster Progenitor: Is the one who spawned all the Dark Ultras. While not the creator of Space Beasts, his mere presence cause them to arise.
- The Mole: He killed Ishibori before the series even started and took his form like a parasite.
- Puppeteer Parasite: It's deliberately ambiguous but he either killed and replaced Ishibori or took him over altogether. Ishibori is definitely dead once Zagi regains his true body.
- Primal Stance: Is noticeably more feral than Noa.
- Red and Black and Evil All Over: Think of it as like a prototype to Ultraman Belial.
- The Sociopath: Cares nothing for his servants or creations, only wants power.
As a whole:The various monsters that Ultraman Nexus and Night Raiders battle throughout the series, the Space Beasts are a race of nightmarish extraterrestrials from the Scorpius constellation that travel from planet to planet, consuming all life. They come in a variety of gruesome forms, but all of them specialize in capturing prey in terrifying manners.
- Always Chaotic Evil: All of their kind are evil and malevolent. Not a single one is either a Gentle Giant, Benevolent Monster or even a Non-Malicious Monster.
- Eldritch Abomination: A race of horrific alien creatures from another galaxy that specialize in spreading terror and devouring sentient beings in the most frightening ways possible.
- Emotion Eater: The Space Beasts feed on the fear of intelligent beings, hence their tendency To Serve Man. The more humans fear them, the more powerful and numerous they become. Thus, TLT established the Memory Police — you can't fear what you don't know about.
- Gratuitous English: Just so we're clear, they're not called "Uchu-ju" in Japan. "Space Beast" is actually what the characters use.
- Kaiju: Most (but not all) of them.
- Monsters of the Week: Averted. Unlike most Ultra Series, the kaiju of this series can last for anywhere between 2-6 episodes before the next threat is introduced.
- Super-Persistent Predator: Sometimes, a fight between a Space Beast and Nexus can just be Nexus struggling to keep it away from its prey.
- To Serve Man: They specifically target and devour humans, usually in the most nightmarish ways possible. However, they don't actually gain any sustenance from humans...
