Voiced by: Ryōhei Kimura (Japanese, anime and motion comic); Josh Hutcherson (English), Daniel Cruz (Latin American Spanish, season 1), Daniel Vargas (Latin American Spanish, seasons 2-3)

The protagonist and new Ultraman.

---

• All-Loving Hero: Shinjiro cares for the well being of the innocent and even when he must fight his enemies, he still shows empathy for them. Just don't push him to the brink of anger. See Berserk Button below.
• Berserk Button: Never hurt an innocent or anyone close in front of Shinjiro or he will go into a rage-filled state. Bemular learned this the hard way.
• Blade Below the Shoulder: As Ultraman, Shinjiro uses the Specium Blades, a pair of energy blades underneath his forearms to use slashing attacks or to deflect projectiles such as lasers.
• Classical Anti-Hero: Shinjiro wants to help people, human or alien, but is often plagued by doubts over his performance as Ultraman and whether or not he's doing the right thing.
• Deadly Disc: The Specium Slash are a pair of energy rings that can be used in hand or thrown to slash through things, similar to the classic Ultraman's special attack Ultra Slash.
• Does Not Know His Own Strength: Shinjiro's attempts to stop a bully from harassing Rena Sayama end up with the bully's leg being broken unintentionally since the bully tried to kick Shinjiro, only for Shinjiro to catch his leg and accidentally crushed it, sending the bully to the hospital and in a cast afterwards.
• Expy: Of Daigo Madoka, both having similar backstories of being descendants of Ultramen and both sharing a Love Interest named Rena.
• Flying Brick: Was born with Super-Strength, Super-Toughness and later develops Flight.
• Good Feels Good: After saving a civilian from a fuel tanker car accident during his trial run as Ultraman, he starts to accept and enjoy the feeling of being the new Ultraman, saving and protecting the people in need. After all, his father, the original Ultraman, was his inspiration to becoming a hero.
• Heart Light: The Color Timer, a traditional piece that applies to many Ultramen. Shinjiro wears this on his suit and it can indicate when the suit's Specium energy levels are running low and glows when his limiters are released.
• Martial Pacifist: As Ultraman, he tries to reason with his enemies rather than jumping straight into battle. Moroboshi scolds him for this.
• Nice Guy: Shinjiro is a genuinely friendly guy since childhood who stands up to protect the innocent and to fight for what's right.
• Power Source: Shinjiro uses Specium, a natural energy source from his body's Ultraman Factor, as the power source to activate the Ultraman suit.
• Powered Armor: Unlike his father's Ultraman form, Shinjiro's Ultraman suit is an advanced suit of powered armor developed by the SSSP and designed to tap into his Ultraman Factor.
• Saying Too Much: He almost lets slip to Rena that he's Ultraman, twice, barely catching himself the first time and doing a poor job of trying to deny it. The second time, he catches sight of Moroboshi shooting him a Death Glare and quickly clams up. However, Rena becomes suspicious and figures it out when he says he's going to call Ultraman but forgets his phone.
• Superman Substitute: To a point. Shinjiro's honestly got more in common with Superboy, being a half human son of Ultraman with similar, if weaker abilities, but also still a Flying Brick.
• Superpowerful Genetics: Shinjiro inherited his father's abilities.
• Super Mode: When Shinjiro releases the limiters in his Ultraman suit, he is able to use the powers of his Ultraman Factor to its fullest extent, allowing him to reach incredible speeds and gain greater strength, also enhancing his special moves. It even gives him a Power Up Full Color Change, making his Ultraman suit give a red glowing effect.
• Wave-Motion Gun: Shinjiro's Ultra Beam is called the Specium Ray, a laser blast of energy that is activated from his forearms.

Shin Hayata / Ultraman I

Shin Hayata

^{Click here to see his Ultraman suit} 

Voiced by: Hideyuki Tanaka (Japanese); Takayuki Sugo (motion comic); Fred Tatasciore (English), Gonzalo Rojas (Latin American Spanish)

The "original" Ultraman and Shinjiro's father.

---

• Amnesiac Hero: After Ultraman left him, he forgot everything about his time as the Giant of Light's host up until Shinjiro and Ide jogged his memories.
• Asskicking Leads to Leadership: Known to be the Japanese Defense Minister and a major figure in the SSSP.
• Beta Outfit: He initially wore a grayscale helmetless armor when he first went back into action. The anime shows him wearing a silver version of the Ultraman armor before receiving the Zoffy upgrade.
• Comic-Book Fantasy Casting: Somewhat obviously, he's modeled after the actor who played him in the original series, Susumu Kurobe, down to wearing the same kind of glasses in the manga.
• Composite Character: His second Ultraman suit has a chestplate design not unlike Ultraman Zoffy's. This is downplayed by the fact that Ultraman Zoffy is implied to exist somewhere in this universe since the events of Ultraman still occurred. Zoffy is later given a proper introduction in the Anime's second season as a suit upgrade.
• Cool Old Guy: 60 years old and still kicking ass.
• Dented Iron: Shin's still a badass, but his powers have weakened due to his age.
• Experienced Protagonist: Known as the first Ultraman in his younger days with the SSSP.
• Hero of Another Story: As the first Ultraman.
• Living Legend: His younger days as Ultraman have earned him fame and many of the people still recognize him as a hero in the present day.
• Papa Wolf: He will destroy anyone who threatens his son.
• Powered Armor: He intervenes in Bemular's attempt to kill his son wearing a black suit of powered armor that gives him a slight resemblance to an Ultra, but isn't quite enough to let him beat an actual Giant of Light.
• Powers via Possession: Shin was the host of the original Ultraman, and still has superhuman strength and durability from his time as the alien's host, which he then passed on to Shinjiro.
• Sizeshifter: In his younger days as Ultraman and as the alien's host, Shin was able to change his size to a larger stature to fight the giant monsters who attacked the city.

Dan Moroboshi / Seven

Dan Moroboshi

^{Click here to see his Ultraseven suit} 

Voiced by: Takuya Eguchi (Japanese); Tomokazu Seki (motion comic); Liam O'Brien (English), Didier Rojas (Latin American Spanish)

A high-ranking SSSP agent as well as Shinjiro's handler.

---

• Anti-Hero: Moroboshi is one of the good guys, but also very cynical in his job as Ultraseven.
• Badass Boast: Moroboshi says these to some of his opponents.
  (Episode 6) "Oh come on, you're joking right, that wasn't really maximum power, was it?"
  (Episode 13) "When I said you could actually fight, I wasn't saying you could actually win."
• Badass Normal: Unlike the other Ultras, Dan doesn't have any innate superpowers and must rely on Powered Armor in combat.
• Clean Cut: Moroboshi's experience with the sword allows him to cut through his opponents with ease.
• The Cowl: While he's not an Ineffectual Loner, his use of gadgets and non-powered status make him come off as the Batman to Shinjiro's inexperienced Superman Substitute.
• Death Glare: Moroboshi constantly sports a stern scowl, but when he catches Shinjiro almost letting slip to Rena that he's Ultraman his glare is so intense that Shinjiro interprets it as a furious rant and is intimidated into clamming up.
• Expy: Of Reiji Moritsugu from Linebarrels of Iron, also written by Eiichi Shimizu. Both were senior members of the defense organization and the main character's senior, both wore Stoic Spectacles, and both used katanas.
• Flash Step: His Ultraseven suit is fast enough to zoom past opponents and use a swift single slash from his sword to disarm his opponents in battle.
• General Ripper: He is a firm believer that the only way to stop an alien from being a threat is to kill the alien, and you're an idiot if you believe otherwise.
• Green-Eyed Monster: It's subtle, but there's more than a few hints that he's honestly jealous of Shinjiro's abilities.
• Good Is Not Soft: Sure, he's one of the Ultramen and he fights to protect the Earth, but that doesn't mean he'll show mercy to the enemies that threaten the planet and its inhabitants.
• Good Is Not Nice: While he has good intentions, he's very blunt and strict towards Shinjiro as a newcomer to the SSSP organization.
• He Who Fights Monsters: He's so distraught at the realization that his twin brother is dead that after the New York arc, he takes the anger over his loss out on the Leo Brothers. Just as he has both of them at his mercy, however, he slowly realizes that Vengeance Feels Empty and he would be no better than the aliens who took his brother if he did the same to Leo by killing Astra. He has a change of heart when the Star Cluster Council unleashes Nova to kill the Leo Brothers and Adad and decides to embrace being an Ultraman, starting off by saving Astra's life and preventing a repeat of his brother's death for someone else.
• Heroes Prefer Swords: Dan's weapon of choice is a specium-powered katana.
• Human Aliens: It's later revealed that Dan is an alien and that his species just happens to look like humans.
• Jerkass: Reflecting Seven's personality in Ultraman Leo and the darkness of his own home series. That said, the original Seven wasn't a bully or vengeful. This one is both.
• Literal-Minded:
  • When Seiji calls him and Shinjiro his "brothers", he assumes Seiji is indeed Shinjiro's sibling only to then believe he's his when Shinjiro denies it.
  • Happens again when Leo and Astra call him "bro", leading to him thinking they're considering him their brother now.
• Master Swordsman: His skill with Japanese swordsmanship is such that he can win a Single-Stroke Battle with a superhumanly-strong alien mercenary, without the alien even realizing he was mortally wounded.
• Smart People Wear Glasses: He wears a pair of glasses and is shown to possess a high level of intelligence and leadership.
• The Stoic: He's very serious about his job and doesn't show much emotion. Becomes Not So Stoic when someone or something angers him.
• Super Prototype: His Mk.VII armor is the basis of the combat gear worn by the Science Patrol's ordinary human Mooks, only the mass production version trades the classic red and silver colors for black and bronze and replaces the distinctive Ultraman mask with what appear to be futuristic motocross helmets.
• Sword Beam: His specium katana is able to produce beams from the blade with a single slash.
• What the Hell, Hero?: Dan constantly chastises Shinjiro on his hesitation and unwillingness to kill.

Seiji Hokuto / Ace

Seiji Hokuto

^{Click here to see his Ultra Ace suit} 

Voiced by: Megumi Han (Japanese; anime and motion comic); Gunnar Sizemore (English), Sergio Barbosa (Latin American Spanish)

A young man who wants to join forces with the other Ultraman.

---

• Ambiguously Bi: He's had feelings for an alien girl named Yuko since childhood, but his conversations with Shinjiro border on flirtation.
• An Arm and a Leg: Seiji is actually an amputee, his arms being prosthetics that constantly get damaged.
• Anti-Hero: Seiji is a mostly decent kid and sides with the heroes, but he isn't afraid to use shadier methods such as blackmail and petty theft in order to support his operation.
• Beware the Nice Ones: Normally he's friendly in a way, but he's not above giving evil-doers and villains a pummeling and taking their money as his income.
• "Blackmail" Is Such an Ugly Word: Funds his operations by extorting criminals.
• Break the Haughty: Twice, first in a subdued way when Moroboshi cuts off his arm during a fight. Later on, when he faces Ace Killer, his confidence gets thrown down the drain courtesy of Ace Killer and his minions putting him through a rather nasty Curb-Stomp Battle, followed by a No-Holds-Barred Beatdown.
• Character Development: The Seiji of earlier volumes was known to preach to Shinjiro about the necessities of a hero needing to get their hands dirty. Seiji by Volume 15 has very vocal objections to the Leo Brothers being willing to let a hostage die in order to get to an enemy.
• Curtains Match the Window: His golden eye color matches with his blonde hair.
• Cyborg: All of Seiji's limbs were amputated and replaced with prosthetics derived from the Ultra suits.
• Decomposite Character: In that Ultraman Ace is just Seiji, not a fusion of him and Yuko Minami.
• Face of an Angel, Mind of a Demon: Don't let his innocent looks fool you. He can get serious when he wants to. Even he's aware of the fact that others view him as weak due to his physical appearance, which he uses to hide his true nature and trick his opponents when he's not in his Ultraman suit.
• Jump Jet Pack: Seiji's Ultraman Ace suit is equipped with thrusters in his back that allow him to jump high, but can't keep him flying in the air for too long.
• Laser Blade: Wields Specium Blades like Shinjiro, but Seiji's blades form together to create a long inward blade for slashing through enemies that dare to charge at him.
• Pint-Sized Powerhouse: The shortest of the Ultramen and is able to handle many fights all on his own.
• Powered Armor: Unlike Shinjiro and Dan's suits, Seiji's Ultraman Ace armor is jury-rigged and not made by the SSSP, but the alien mechanic Yapool.
• Roaring Rampage of Revenge: Against those responsible for the death of his family.
• Smug Snake: Despite being one of the good guys he counts, being very haughty and condescending towards both Shinjiro and Moroboshi, believing he's the superior Ultraman. Then Shinjiro manages to hold his own against him, and his fight with Moroboshi is an utter Curb-Stomp Battle in the latter's favor. He doesn't take it well.
• "The Reason You Suck" Speech: Gives one to Ace Killer after slicing off one of his arms.
  Seiji: "Now you're gonna pay for what you've done! For taking the lives of everyone on that plane! For destroying Yuko's happiness! You murdering scum!" *Points at Ace Killer* "Your life won't begin to make up for all that, but you're gonna pay anyway!"
• Ungrateful Bastard: Shinjiro, Moroboshi, and two squads of SSSP agents mobolize to back him up against Ace Killer 's group at the behest of a worried Yapool, but Seiji actually spots them and sits back so they can spring the likely ambush for him. The SSSP agents are all killed, and Shinjiro and Moroboshi end up being tortured for their trouble, while Seiji smugly remaks that that's what they deserve for sticking their noses into his business.
• Vigilante Man: Administers rough justice on criminals, be they human or alien, and takes their money if they're loaded.

Jack

Jack

^{Click here to see his Ultraman suit} 

Voiced by: Ryota Takeuchi (Japanese); Keiji Fujiwara (motion comic); Robbie Daymond (English), Oscar F. Gomez (Latin American Spanish)

A resident of a hidden alien city who acts as Moroboshi's informant.

---

• Adaptational Villainy: Jack is a much more duplicitous and morally ambiguous character than Ultraman Jack. Though by Season 2 he's a little bit closer to his heroic Toku counterpart.
• Ambiguously Human: It's not clear if he's a Human Alien or not, just that he appears normal but has enough strength to punch out an alien twice as big as him in a fight.
• The Big Guy: He's unnaturally strong, and it's taken further by his own Ultraman suit which is built like a tank.
• Double Reverse Quadruple Agent: His moral ambiguity is highlighted when he sends a vengeful giant alien after Shinjiro in order to force him to fight, and the final episode implies he's working for the Star Cluster Alliance when he abducts Yapool and takes out the SSSP agents guarding him.

Kotaro "Taro" Higashi

Kotaro "Ultraman Taro" Higashi

^{Click here to see the Ultraman of New York} 

^{Click here to see Taro} 

^{Click here to see his Ultraman suit} 

Voiced by: Tomoaki Maeno (Japanese); Roger Craig Smith (English)

A photographer who unexpectedly acquires superpowers and decides to be New York's Ultraman. He later gets recruited by DARPA as one of their agents despite not having American nationality.

---

• Beta Outfit: His first costume was a spandex throwback to Ultraman Taro's original appearance. After Dave's death, he abandons the superhero identity and is now normally a nude human engulfed in fire with two fans of flames on his head being nods to Taro's iconic horns. He later gets his own Powered Armor that's more reminiscent of the classic Ultraman Taro.
• Break the Cutie: He was an optimistic photojournalist who was thrilled to be gifted superpowers so he can be a real life superhero. Unfortunately, his best friend ends up being killed due to his activities as New York's Ultraman and he becomes much more vengeful and cynical as a result.
• Camera Fiend: His initial attempts to dish out justice was as a photojournalist.
• Hot-Blooded: Matching with his pyrokinetic powers, Taro shows himself as fairly dramatic and eager to kick the asses of those he deems deserve it, which ends up earning Valky's attraction towards him.
• Playing with Fire: His primary ability is to engulf himself in flames.
• Ship Tease: With Valky after she kisses him after their fight.
• Spider-Man Send-Up: A variant, in that Kotaro is specifically an expy of Spider-Man's civilian identity, Peter Parker; he's a young photojournalist living in New York who treats his new superpowers as something to have fun with until the death of someone close to him teaches him responsibility.
• That Man Is Dead: Following Dave's death, Kotaro now refers to himself as "Taro."

Leo Brothers

Leo and Astra

From left to right: Astra and Leo

^{Click here to see their "original" forms} 

The Star Cluster Council's elite assassins, later joining the SSSP after they are deemed no longer of use to the Star Cluster.

---

• Adaptational Wimp: Much more so than the other Ultramen in the series. Those other characters have the excuse of undergoing Adaptational Species Change to become either regular humans or Human Aliens that have no connection to the actual Ultramen in this universe. Leo and Astra however have kept their origins as aliens hailing from Planet L77 but are no longer Ultramen-like beings.
• Adaptational Villainy: They're the Star Cluster Council's elite assassins and display contempt for any illegal aliens of any kind. It gets downplayed once they are humbled by the battle with Nova and join the SSSP out of gratitude for Moroboshi saving them.
• Adapted Out: They are absent in the anime.
• Animal Motifs: Much like their original counterparts, they have lion themes. Leo especially.
• Even Evil Has Loved Ones: They genuinely care about each other as brothers and are outright inseparable.
• Decoy Antagonist: The Hong Kong arc introduces them as the Arc Villains hunting down Adad and the enemies Moroboshi fights. They are quickly defeated when Moroboshi turns the tide and are dethroned as the arc's main antagonist by Nova, who is literally a much bigger threat that threatens to flatten the entire sector of Hong Kong for the Leo Brothers' failure to kill Adad.
• Heel–Face Turn: They start off as antagonists but after Moroboshi saves their lives from Nova, they join the SSSP. And in high contrast to their behavior when we first meet them, they are pretty cordial and chummy with the people they've decided to work with.
• Horned Humanoid: Leo's "original" form, which takes directly after his Ultraman design.
• Human Aliens: Downplayed. They have Pointy Ears, wild Anime Hair, fangs, and claws, but resemble humans enough for Rena to not notice anything off about them. Their default appearances are also not how they actually look.
• I Owe You My Life: Their gratitude to Moroboshi for saving their lives makes them switch sides and join the SSSP.
• Last of Their Kind: Like their original counterparts, they are the sole survivors of Planet L77.
• Saying Too Much: Much worse about it than Shinjiro, though to be fair it seems that nobody bothered to tell them that the SSSP's operations are supposed to be secret and the museum is a front, causing them to accidentally reveal Moroboshi's full name and connection to the place to Rena.
• Super Mode: They have "original forms" that they seem to want to actively avoid using. These forms more directly harken back to their original Ultraman designs.
• You Have Outlived Your Usefulness: They are quickly marked for elimination when they fail to kill Adad, causing the Council to send Nova after them. Edo later acquits them of their bounty.

The Ultrawoman (SPOILERS!)

Rena Sayama/Marie

^{Click here to see her Ultraman suit} 

Voiced by: Sumire Morohoshi (Japanese); Maaya Uchida (motion comic); Tara Sands (English)

An idol singer who has an interest in the current Ultraman and seeks him out.

---

• Adaptational Early Appearance: The anime has her show up in the first episode as one of the girls Shinjiro rescues from thugs, while in the manga it was just a random girl.
• Adaptational Intelligence: Downplayed. She manages to figure out that Shinjiro is the new Ultraman in the anime while in the manga she came close but ultimately didn't realize. To be fair to the manga version though, the only reason Rena learns that he's Ultraman in the anime is because he accidentally leaves his phone on the the table when goes to "call" Ultraman to save some men from falling off a scaffolding, only for Ultraman to appear anyway. Shinjiro doesn't make this mistake in the manga, so she isn't able to connect the pieces.
• Adaptational Jerkass: While her crush on Ultraman is genuine in the manga, it was not only for publicity reasons in the anime but she secretly hates Ultraman since she blames him for the death of her mother while during one of the original Ultraman's battles. She later drops the behavior after he saves her life.
• Canon Character All Along: It's eventually revealed that her real name in the manga is Marie. As in Ultrawoman Marie, better known in the regular Ultra Series as Mother of Ultra.
• Clark Kenting: Rena apparently goes around in public wearing a pair of glasses to avoid attention.
• Dating What Daddy Hates: Her father, a police detective, despises Ultraman - something she's well aware of. However, she has a crush on him in the manga (while her father admires the original and simply saw the current one as an impersonator), though in the anime her interest in Ultraman is more an act for publicity purposes and she actually hates Ultraman just as much as her father does... at least until Shinjiro-as-Ultraman risks his life to save her.
• Early-Bird Cameo: Advertisements for her performances are littered around in the earlier chapters before she actually appears.
• Expy: Of Rena Yanase, serving as the love interest of a protagonist who is the descendant of an Ultraman and inherits the mantle.
• Forgotten First Meeting: In the anime, she finds Shinjiro so forgettable that she forgets him twice after he saves her from some thugs who accosted her. She's embarrassed when he reminds her who he is for the second time.
• Half-Human Hybrid: In the anime, it was revealed that her mother was an alien and that it was the stress of giving birth to her alien/human daughter that really killed her. In the manga, her parents were aliens living on Earth and were killed prior to being adopted by Endo.
• Hidden Depths: Her dad's police skills have rubbed off on her, as she proves to be a skilled-enough amateur detective to figure out that the Ultraman Museum is a front for the SSSP and that Shinjiro is the new Ultraman. She has a long way to go in terms of crafting disguises, however.
• Human Alien: Her parents were aliens hiding on Earth. After they were murdered, she got adopted.
• Idol Singer: She's a popular idol singer who Shinjiro has a massive crush on, to the point where he considers telling her that he's Ultraman. Rena Sayama is her stage name, and her real name is Rena Endo, the daughter of a police detective.
• Irony: She intinally hated Ultraman because she believed her mother was killed during a battle. Turned out this was far from the truth as both her biological mother and father were indeed killed, but it was because they lost the protection of the Ultra race after they were banished.
• Jerkass Realization: She blamed Ultraman for the death of her mother and refused to see him as a hero. But after being used in Adad's Sadistic Choice against him, she's forced to realize that what Ultraman does is no easy walk in the park.
• Loves My Alter Ego: In the manga, Rena has a genuine crush on Ultraman. In the anime, however, she initially holds a grudge against him due to one of the original Ultraman's battles (implied to be the fateful encounter against Zetton) causing the death of her mother. Unlike her father, however, she's able to recognize that her mother's death was a tragic accident, and stops blaming Ultraman for it.
• Misplaced Retribution: She hates and blames Ultraman for causing her mother's death. The problem with this is that she's taking her anger out on said Ultraman's son who wasn't even born at the time. Shinjiro's guilt over this doesn't help either. Later it turns out that the death of her mother largely happened because her mom's alien biology (as well as some injuries she got in a fight with Ultraman and an enemy) couldn't handle the stress of her birth.
• Oblivious to Love: She doesn't seem to be aware of Shinjiro's feelings for her, even if she eventually cares about him as a friend. Though it's implied she's begun reciprocating before she leaves for New York.
• Paper-Thin Disguise: Her idea of an adequate disguise is nothing but a pair of glasses, and is shocked when Shinjiro immediately recognizes her when she adds a hat. Her manager scolds her for being so thoughtless as to think that would actually work.
• Put on the Bus: Subverted. She leaves for New York to look for work after her disastrous concert tour, but after the Star of Darkness incident she is forced to return to Japan.
• Secret-Keeper: She ultimately figures out that Shinjiro is the new Ultraman, but decides to keep it a secret out of recognition that he's trying to be a hero.
• Ship Tease: She's the target of a one-sided crush on Shinjiro's part but it's implied to eventually be reciprocated when she returns from New York. She can even be seen looking embarrassed when Leo and Astra ask if she's Shinjiro's girlfriend.
• Shout-Out: Her suit transformation sequence and ending pose in the anime is a deliberate one to Sailor Moon.
• Stage Names: Sayama is not her real surname.

SSSP

Mitsuhiro Ide

Voiced by: Ken Uo (Japanese); Masashi Ebara (motion comic); Brian Palermo (English), Harold Leal (Latin American Spanish)

The friend of Shin Hayata and Shinjiro. He, along with Shin Hayata, is one of the original members of the SSSP team and is the technician of the current organization.

• Cool Old Guy: Ide's an outgoing and friendly man, as well as an uncle figure towards Shinjiro.
• Mission Control: He assists the Ultramen by mapping out their missions and analyzing their suits status and limiters.
• Living Legend: One of the original members of the SSSP, but not as famous as his friend Shin.
• Nice Guy: He's overall a pretty friendly guy, especially compared to the likes of Moroboshi.

Edo

Voiced by: Shigeru Ushiyama (Japanese, anime and motion comic); D.C. Douglas (English), Giovanni Cruz (Latin American Spanish)

A surviving member of the Zetton alien race, and a liaison for the Star Cluster Alliance.

---

• Accent Upon The Wrong Syllable: He speaks in a very disjointed unnatural tone.
• Aliens Speaking English: Justified with that extremely thick and off-putting accent of his.
• Badass in a Nice Suit: He's dressed in a three-piece suit when Shinjiro first meets him.
• Big Bad: Turns out to be this in the anime, where he's been behind several events and his endgame plan is the climatic final arc of the series.
• Cyclops: Like other Zetton aliens, he only has one eye.
• Evil All Along:
  • It's revealed that the Star Cluster Alliance Council — who Edo is revealed to be the Supreme Chancellor of — were behind the plane explosion, framing Bemular, Yapool seems to know who he is and panics when he sees him.
  • Later down the line he's shown to be part of the Zetton Core, who have destroyed alien races that support the Ultras and created the Star Cluster Alliance as means of having control of the Universe by imposing their will.
• Evil Counterpart: To the Ultramen in general, and he even uses his own suit which is themed after Zetton as well.
• Final Boss: He's the final opponent in the anime.
• Perpetual Expression: Zig-Zagged. While he appears to remain with a single expression due to his lack of a mouth and a single eye, there's apparently a way to "read" his facial movements to know what he's feeling at a time.
• Pragmatic Villainy: He berates Black Directive for his excessive and impractical attempt to silence the Leo Brothers through Bioweapon Nova and decides to lift the bounty on them and Adad to let bygones be bygones for the time being.
• The Unmasqued World: His agenda includes the exposure of aliens living amongst humans.
• Vocal Dissonance: His voice alternates between being deep and very deep. This is especially more accentuated in the Latin American Spanish dub, as a result of his voice actor's Colombian accent.

Aliens

Bemular

^{Click here to see his first suit from the Manga} 

Voiced by: Kaiji Soze (Japanese); Tsutomu Isobe (motion comic); Matthew Mercer (English), Brian Gomez (Latin American Spanish)

An enigmatic Giant of Light who serves as the series' first antagonist.

---

• Absurdly Sharp Claws: His gauntlets are tipped with claws sharp enough to rip through advanced combat armor, and he puts them to good use in combat.
• Adapted Out: His first Suit from the Manga is never seen in the Anime, as he dons his secondary suit from the start. It doesn't really affect the plot.
• Adaptational Villainy: While his morals are somewhat vague but ultimately heroic in the manga, he comes across as far more outright villainous in the anime adaptation. For one thing, his more humanizing scenes such as Shin admitting that Bemular could have easily killed him if he truly wanted to or his interactions with Officer Endo are Adapted Out. But even worse is during the anime version of the Rena Sayama concert, where he nearly drops the ceiling on the crowd and would have killed hundreds of people if Shinjiro hadn't caught it.
• Big Bad: Subverted. Despite introducing himself as Shinjiro's first major enemy and being all-around shady, he isn't a villain at all and is, in fact, the original Ultraman who is working towards the greater good against the Star Cluster Alliance.
• Body and Host: Bemular's current body is actually just another host, similar to Hayata. According to Yapool, the host was a corpse floating in space before they merged.
• Breath Weapon: In the manga, he can breathe flames from his mouth.
• Combat Pragmatist: He doesn't hesitate to use surprise attacks or slash at opponents with his armor's claws and bladed protrusions.
• Composite Character: He has the name of the very first enemy Ultraman faced and is actually Ultraman himself.
• Evil Sounds Deep: His voice has a deep, metallic tinge.
• Fallen Hero: Bemular kicks off the story by destroying a plane, attacking Shinjiro, and nearly killing Hayata. Even with him getting framed for the plane, he still commits several unsavory acts throughout the story. He's revealed to be The original Ultraman, who has been on the run from the Star Cluster Council.
• Good All Along: He is introduced destroying a plane, then twelve years later attempts to kill Shinjiro but then its revealed that he didn't actually destroy the plane, he was trying to save it and his attempts to "kill" Shinjiro were never serious, he was merely testing him and never had any real intention to harm him, let alone kill him.
• Glowing Eyes of Doom: An eerie bright blue.
• Greater-Scope Paragon: His identity as the original Ultraman makes him this for the entire Manga, as Ultraman is still revered as a hero for his exploits on Earth and the events of the Manga never would have happened if he hadn't arrived on Earth.
• Hand Blast: He can fire beams and blades of energy from his hands, and he tries to kill off Shinjiro with an enormous star-like energy ball.
• Healing Factor: He regenerated one of his arms after getting it blown off by Shinjiro.
• Kame Hame Hadoken: He fires off a Specium Beam to destroy an alien mothership in the anime.
• Just Toying with Them: Shin mentions that Bemular was holding back significantly during their fight, and could have easily killed him and Shinjiro at any time.
• Major Injury Underreaction: His response to getting an arm blasted off by Shinjiro's Specium Beam is to glance at it and ask if that's the best he can do.
• Mythology Gag: His chosen name and comment that he's "the first enemy" are a nod to the original series and the first kaiju that an Ultra ever battled.
• Not Quite Dead: He's seemingly killed by Temperor, but is soon revealed to have fled this body, and returned to a noncorporeal state to search for a new vessel.
• Not So Stoic: His usual serious demeanor is thrown off-balance by Rena's rather dorky reaction to having confirmation that she has powers.
  Rena: My power... is... the ability to make everyone smile as an idol! Right?!
  Bemular: N-not exactly...
• Possessing a Dead Body: It's later revealed that Bemular is possessing the body of a long dead alien, a body which was destroyed but never entirely alive when Temperor seemingly killed him.
• Rogue Agent: Formerly working for the Star Cluster Alliance, he has now gone rogue. It is implied that this is only because the Alliance Council has become corrupt.
• Scary Teeth: When his first suit's mask is broken in the manga, it's revealed he has shark-like fangs.
• Sink or Swim Mentor: He claims he wants to see if Shinjiro is worthy of bearing the Ultraman Title, which apparently involves multiple attempts to kill him to see if they can survive his onslaught. He's ultimately just testing Shinjiro and has no intention to kill either him or Hayata.
• Starter Villain: He outright calls himself "the first enemy".
• Walking Spoiler: He's the original Ultraman.

Adacic

Voiced by: Yuuichi Hose (Japanese), Yamato Kinjo (motion comic), Xander Mobus (English)

A Baltan-adjacent alien feeding off Tokyo's human population, Adacic is the second alien opponent Shinjiro faces as Ultraman.

---

• Adaptational Badass: He's far more dangerous in the anime, with him completely overwhelming Shinjiro for most of the fight. And while Shinjiro effortlessly dispatches him after after getting his limiters released in the manga, the anime has his still put up a fierce fight, even pulling out a trump card.
• Arc Villain: For chapters 7-8 of the manga, and episodes 3-4 of the anime. He's Shinjiro's second alien opponent, but his first real outing as Ultraman.
• Asshole Victim: Consumed several earthlings for food and gloats about how often he got away with it to Shinjiro, who then proceeds to tear off one of his arms and vaporize him with a Specium Ray. A little disproportionate? Maybe. Did the sicko deserve it? Absolutely.
• Ax-Crazy: Brutally kills people with childish glee.
• Composite Character: He's literally a Cicada Human/Alien Baltan hybrid.
• Does This Remind You of Anything?: The fight between Shinjiro and Adacic evokes a Wake-Up Call Boss fight in an RPG, with the protagonist's allies deciding This Is Something He's Got to Do Himself, the villain No Selling attacks that had worked well prior to that point, and finally, Mission Control prompting the protagonist to Level Up.
• Faux Affably Evil: Is able to pass as a normal human between feeding frenzies.
• For the Evulz: It's implied he could easily buy the nutrients he needs in the alien city, and that he only hunts humans just for the hell of it.
• The Illegal: His species has been banned from Earth, so he snuck in illegally.
• Impersonating an Officer: Disguises himself as a human security guard.
• Meaningful Name: Adacic is "Cicada" spelled backwards, an allusion to the Cicada Men from Ultra Q.
• Me's a Crowd: Pulls this in the anime when he decides to overwhelm Shinjiro.
• No True Scotsman: He was hoping that the Ultraman that would come after him would be Ultra Seven or maybe even the original. He could tell from Shinjiro's inexperience that he's neither and expresses some disappointment that he's not facing the "real" Ultraman.
• Sdrawkcab Name: Adacic is cicada Spelled backwards.
• Starter Villain: While technically Shinjiro's second opponent, defeating Adacic is his first real assignment as the new Ultraman.

---

• Adaptational Wimp: He has no Kaiju-like true form in the anime.
• Alas, Poor Villain: All he wanted was to enjoy Rena's work as an idol. He even did his best to protect Rena when Adad seemingly threatens Rena on the stage. It's especially potent in the manga, where he see a flashback of him when he first immigrated to Earth and how miserable he was before he discovered Rena.
• Arc Villain: For episodes 5-8 of the anime.
• Big Bad Wannabe: His real crime was just a poor choice of friends. And he's easily dispatched by the True Final Boss of his arc before he can fight an Ultraman.

• Hikikomori: Spends most of his time in a dingy apartment glued to a computer screen.
• In the Hood: Wears a hoodie that conceals his upper set of eyes enough to pass as human.
• Last of His Kind: Is believed to be the last surviving member of his species before officially becoming extinct.
• Loony Fan: Of Rena.
• The Unfought: Adad kills him before he has a chance to fight Ultraman.
• Yandere: His obsession with Rena makes him a borderline Rare Male Example, though it's also implied that he would probably would have been harmless if he had not been manipulated by his Toxic Friend Influence.
• You Can't Go Home Again: In his case, because his homeworld was destroyed.

Bris

An alien assassin who is an accomplice in the Rena Sayama murders.

---

• An Arm and a Leg: He's literally disarmed by Moroboshi within a minute of their confrontation.
• Curb-Stomp Battle: On the receiving and an extremely one-sided and cathartic beatdown by Moroboshi.
• Dirty Coward: He gets a sadistic kick out of killing defenseless humans, but when faced with an opponent who can fight back and beat him, he pathetically pleads for mercy. Moroboshi has none for him.
• The Dragon: He's the one carrying out the murders, directed by Pigmon.
• Expy: Of Alien Metron.
• The Illegal: An alien immigrant whose race has been barred from Earth.
• No-Sell: His tough hide renders him immune to small arms fire. Endo and Kurata pumped their entire magazines into him and he wasn't even scratched.
• Pre-Mortem One-Liner: Subverted. He would have done in Endo and Kurat, but the timely intervention of Moroboshi prevents him from following through.
  Bris: You're police, aren't you? What they call "cops"? Well, now you're ex-cops!
• Psycho for Hire: A sadistic thug who was hired to kill a bunch of humans for the crime of speaking negatively of Rena Sayama.

• Avenging the Villain: One of his older relatives fell in battle against the original Ultraman, and he's harboring a serious grudge.
• The Brute: Crude, violent, and not very smart.
• Canon Foreigner: He's unique to the anime, essentially filling the role Red served in the manga.
• Continuity Nod: Implied to be the son or younger brother of the original Black King.
• Does This Remind You of Anything?: The general implication is that his role in the alien city is "drunken violent troublemaker."
• Kaiju: A relatively man sized one, standing at a still towering 12 feet.
• Mythology Gag: In the original toku, his opponent was Ultraman Jack. In the anime, he is introduced battling Jack at the alien fight club.

Yapool

Voiced by: Akio Nojima (Japanese, anime and motion comic), Mick Wingert (English)

An illegal extraterrestrial immigrant and fugitive from the Star Cluster Alliance who works as a mechanic in the alien city.

---

• Adaptational Heroism: His namesake was actually the Big Bad of Ultraman Ace. Here, he's a major supporting character and an ally to Seiji who he also sees as a surrogate son.
• Adaptational Wimp: The original Yapool was an immortal Eldritch Abomination that created monsters of all kinds, could resurrect the dead and himself, and was capable of fighting the giant Ultras on equal grounds. This Yapool has no combat ability and is very limited in his creations (which are mainly mechanical) as he requires large amounts of money to build and upgrade Seiji's suit in the first place, even if they're powerful by themselves.
• Adaptation Species Change: Goes from an Eldritch Abomination-like entity whose body is made of the Minus Energy to a normal alien who has no real powers.
• Distressed Dude: At the end of the anime's first season, Jack kidnaps him and takes him to parts unknown. By Season 2 it's revealed that he was taken to New York as part of an initiative to give the United States its own Ultraman.
• Gadgeteer Genius: He built Seiji's prosthetic limbs and managed to reverse engineer the SSSP Ultraman Armor for him to use. By Season 2 he is now filling this role for Jack and Kotaro.
• In Name Only: Outside of his name and appearance (And his redesign is still rather different) he barely resembles the original Yapool.
• Like a Son to Me: He looks after Seiji and expresses consternation regarding the human youth's vengeful streak. Seiji doesn't reciprocate or appreciate the sentiment, however.
• Oh, Crap!: When he sees Edo approaching him, he panics and flees to the SSSP.

Ace Killer

Voiced by: Hiroaki Hirata (Japanese); Ray Chase (English)

The captain of an elite mercenary hit squad, who also runs a human harvesting operation on Earth. He claims that he is more like a contract killer than a mercenary and took the name "Ace Killer" to show that he is the best in the business.

---

• Adaptational Badass: His anime incarnation can resurrect himself from the dead (as long as his head is not destroyed) and it takes a fully powered Specium Ray to finish him off. He also outlives all of his squad whereas he was the second-last to die in the manga; and if that wasn't enough, has a Kill Sat as a backup plan just in case he dies.
• An Arm and a Leg: Had his arm that carries his blaster sliced off by Seiji's Specium Blade.
• Arc Villain: From episodes 9 to 13 of the anime. He doesn't physically appear until the eleventh episode, but Ace Killer's involvement in the airplane disaster is what drives Seiji to become an Ultraman, which kicks off the first season's final arc.
• Arch-Enemy: Destroying that airplane earned him Seiji's ire for years after the fact.
• Arrogant Kung-Fu Guy: Though he can back it up most of the time. He stubbornly clings to the belief that nobody can ever defeat or kill him. Then Shinjiro proves him how very wrong he really is.
• Asshole Victim: The moment this unpleasant monster and delusional prick, who killed a plane full of innocent people, including children, gets a well-deserved thrashing and is reduced to nothing at the hands of Shinjiro, a 'lousy' human is nothing short of satisfying.
• Ax-Crazy: When Moroboshi tells him that he is not as professional as a mercenary should be, his response amounts to At Least I Admit It and makes no attempt to deny that he just enjoys killing.
• But for Me, It Was Tuesday: The airplane bombing was just another day at the office for him.
• Create Your Own Hero: In bombing the airplane, Ace Killer unwittingly created his own enemy in the form Seiji, who goes on to become this adaptation's Ultraman Ace.
• Final Boss: For Season 1 of the anime.
• Flash Step: His charge/dash attack is so fast, he appears to teleport to the human eye.
• Hate Sink: The most despicable alien to date as he is a cruel, petty Smug Snake who spends most of his screentime cycling between "arrogant douchebag" and "sadistic monster".
• Jerkass: Even when he's not being a murderous psycho, he's just an incredibly unpleasant and arrogant scumbag to be around, and this is the nicest he gets.
• Kick the Dog: Ace Killer tortures and trolls the Ultramen for his own amusement like...
  • Repeatedly shooting a downed Shinjiro at the soft part of his armor with painful yet non-lethal shots.
  • He does the similar thing to Seiji only have his henchmen do it by all surrounding him and shoot at the same time.
  • (In the anime) After resurrecting, he kicks around a incapacitated Seiji and stomps on his face.
• Made of Iron: Has a Healing Factor that enables him to regenerate from lethal injuries.
• No Body Left Behind: In the anime Shinjiro completely disintegrates him with a supercharged Specium Ray.
• Not Quite Dead: Deviating from the Manga, while Seiji does succeed in offing Ace Killer, it doesn't stick very long, since he revives shortly after Seiji collapses. He dies for good at Shinjiro's hands, and even then, it takes a fully powered Specium Ray to do him in.
• Powered Armor: He wears a suit of armor that strongly resembles the Ultra Suits, but is even more powerful.
• Psycho for Hire: Moroboshi backhandedly calls him one, and Ace Killer rather takes it as a compliment.
• Resurrective Immortality: He can resurrect as long as his head is attached to his body. At least in the anime.
• Sadist: He really loves to play with his food, and takes his sweet time doing so, like filling his victims with non-lethal but extremely painful rounds. However, this would actually end up being his downfall.
• Smug Snake: He has a real inflated ego and loves to believe that he is some great assassin who is invincible and undefeated which does have some merits, however, he uses his own henchmen to make things easier for him or when he gets beaten and killed by Shinjiro (In the anime)/Seiji (In the manga).
• Stupid Evil: In the anime, he manages to resurrect after being killed by Seiji and rather then just kill the downed Seiji right then and there, he instead decides to brutalize the downed ultraman out of pettiness for awhile then makes a declaration that he will make a trophy out of Seiji's skull before he finally is about to stab him however at this point Shinjiro was enraged enough to to be able escape his bind via activating his Limiter and quickly stops Ace Killer from dealing the final blow to Seiji. Ace Killer is eventually taken down for good due to his rather needless sadism and smug arrogance.
• Sword and Gun: Wields a blaster pistol and a bladed weapon that looks like a cross between a sai and a tomahawk.
• Taking You with Me: In the anime, after he's killed, his weapon sends up a signal to a cloaked Star Cluster Alliance ship, which launches a massive missile at the SSSP Ultraman team as his final act of spite. Fortunately, Bemular shows up to vaporize the missile and the ship that fired it, foiling Ace Killer's posthumous attempt.
• Torso with a View: Seiji blows a hole through his chest with a hidden Arm Cannon, which is enough to kill him in the manga. The anime has it so that he unfortunately promptly resurrects after Seiji collapses.
• Unrelated in the Adaptation: Isn't a creation of Yapool nor a guise he takes and has no real connections with him beyond both having worked for the Star Cluster Alliance.
• Villainous Breakdown: In the anime he starts losing his smugness and cool when he finds himself no match for an limiter released Shinjiro and is getting thrown around.
  Ace Killer: "This ain't right! Why am I having so much trouble with a lousy human?!"
  • ... and vainly tries to charge at him only to face a Specium Ray head on and literally turned into nothing.
    Ace Killer: NO ONE HAS EVER BEATEN ME! NO ONE!!! *Disintergrates into nothing*
• You Killed My Father: Killed Seiji's family on the plane.

An exiled Wadoran princess living in the alien city. With her species facing extinction, Maya is determined to save her people by any means necessary.

• Amazing Technicolor Population: Has blue skin in her true form.
• Anti-Villain: She harbors no hatred against Earth or humanity. All she wants is to save her people.

• Driven to Villainy: Does not actually WANT to do the various misdeeds that Pedant is ordering her to do, but she must honor her contractual obligations to him if her people are to survive.
• Freeze-Frame Bonus: When her face is turned away and Shinji is mourning her sacrifice she sticks her tongue out and cracks a goofy face at him buying her faked-death like a sucker.

• Heroic Sacrifice: Makes one to save the humans captured by Pedant.

• Authority Equals Asskicking: Leads the Blackstars, and is strong enough to take on six Ultramen.

• Expy: Of Thanos: An extraterrestrial Evil Overlord who comes to Earth intent on eradicating half of its population. When Earth’s resident superheroes attempt to stop him, none of them are strong enough to go toe to toe with him individually, so it takes ALL of them, operating at full power, to put him down.
• Extra Eyes: In the anime he never appears unmasked, but we do see that he has four eyes.
• Large Ham: Chews a lot of scenery during his televised ultimatum to the people of Earth, and during the final battle with the Ultramen.
• Me's a Crowd: Can create multiple copies of himself.
• My Death Is Only The Beginning: His death was necessary to proceed to “the next phase” of the plan.

A member of the Star Cluster Alliance's Immigration Administration Bureau, Adad serves as the Alliance's primary operating agent on Earth.

---

• Affably Evil: He apologizes to Rena and her fans for the troubles he has caused while politely introducing himself to the Ultramen. Though later on the evil part gets toned down into moral ambiguity.
• Ambiguously Evil: Introduced taking hostages at one of Rena's concerts, threatening to kill her, and battling Ultraman... but this turns out to be just an elaborate undercover operation. After this, he settles into John le Carré levels of moral ambiguity.
• Cowboy Cop: Adad is the de facto Sheriff for the alien city, preferring to deal with its criminals quietly and pragmatically. To him, breaking the laws of Earth or the Alliance is a small price to pay for keeping the fragile peace between humans and aliens. Consequently, Adad is seen as a maverick by the Alliance, who harbor some mistrust toward him due to his unorthodox methods.
• Double Reverse Quadruple Agent: Is working for the Star Cluster Alliance, which is implied to be corrupt, but also appears to be working against it on some level as he continues to support Bemular after he goes rogue.

Valky

Voiced by: Mao Ichimichi (Japanese)

A freelance killer hired by the Star Cluster Alliance to do their dirty work.

---

• Adaptational Hairstyle Change: The anime replaces her long free flowing hair with a pair of static pigtail-like structures. Most likely because long hair is notoriously difficult to animate with CGI.
• Aliens Among Us: Can take the guise of a human tour guide girl to go unnoticed.
• Cosplay: She at one point has her human disguise dress as a Magical Girl to impress Taro after mistakenly thinking it's a legitimate trendy outfit.
• Double Reverse Quadruple Agent: She's actually a spy working for Edo, and claims to be on the side of Earth.
• Gender Flip: Previous Alien Valkies in the franchise were male, this one is a female.
• Foe Romance Subtext: With Taro, best exemplified with her kissing him while ending their first battle.
• Hotter and Sexier: The original Alien Valky looks like another in a long line of Evil Ultramen. Here, the Gender Flip applied to her results in her rather curvy appearance leaving little to the imagination.
• In Love with Your Carnage: She's highly attracted to Taro's Hot-Blooded nature. His enraged rant about his hatred for those who freely kill innocents makes her blush and seems enough for her to kiss him.
• Psycho for Hire: An assassin hired by the Star Cluster Alliance for any dirty job or assassination they require.
• Never My Fault: In spite of actively and knowingly leading her "clients" to their human victims, she denies any responsibility for their actions and places the blame on them and her bosses.
• Nothing Personal: She repeatedly insists that it's just her job to guide murderous aliens to hapless humans to kill.
• Villainesses Want Heroes: Falls in love with Taro during their fight and even kisses him in the mouth when it's over.
• Women Prefer Strong Men: Her attraction to Taro includes his No-Sell to a supposedly inescapeable hardening substance.
  Valky:...How strong are you?

---

• Kaiju: Unlike previous monsters and aliens in the series this one is actually giant, big enough to tower over buildings.
• Villain: Exit, Stage Left: Is recalled by the Alliance once Shinjiro and co. turn the tide of the fight in their favor.
• You Don't Look Like You: In a series full of redesigns for various aliens, Nova is a surprisingly Subverted example as it has the exact same look it has in the rest of the Ultra Series.

Zetton Core

Damned

• Cyclops: Like other Zetton aliens, he only has one eye.

Civilians

Daisuke Arashi

Ex-SSSP member who left after the events of Ultraman over Shin's plans to get Shinjiro involved with the Ultramen.
