ZAP SPACY (Zata Astronomical Pioneers Spacy)
Rei
- Played by: Shota Minami
- The Berserker: When he transforms into Burst Mode he becomes a near-mindless brute fighter who won't relent from attacking, even if his opponent dies.
- Blue Is Heroic: His Reimon form is primarily blue and he's The Hero.
- Henshin Hero: A rare non-Ultra example of the series. With his Battle Nizer/Battle Nizer NEO he transforms into an Ultra-like form, Reimon which he can utilize to battle other Reionics.
- Human Aliens: Looks human but actually is an alien of a species named Alien Reiblood.
- Ineffectual Loner: At first, he warms up to ZAP overtime though.
- Jerk with a Heart of Gold
- Nice Guy: What sets him apart from most Reionics. He would rather not fight the other Reionics. And ultimately averts becoming Reiblood's successor/host.
- Red Eyes, Take Warning: His Burst Mode, wherein he goes full berserker, has red eyes.
Captain Hiroshi Hyuga
- Played by: Hiroyuki Konishi
- Cool Old Guy: An old man who can still kick alien ass and leads a group of humans travelling through space and fighting giant monsters on a daily basis.
- Parental Substitute: To Rei, who has no birth family to speak of.
Jun Haruna
- Played by: Saki Kamiryo
- Action Girl
- Defrosting Ice Queen: Initially, she was the most wary towards Rei and treated him with pointed skepticism. However, she gradually warmed up to him overtime. When Asuza (who was actually Kate in disguise) tried to frame Rei for the destruction on Bolis, she stands up for him.
Koichi Oki
- Played by: Toru Hachinohe
Masahiko Kumano
- Played by: Mitsutoshi Shundo
- The Engineer: Serves this role for the Pendragon and its crew.
Rei's Monsters
Gomora
- First Appearance: The Lawless Monster Planet
See Ultraman TV Series
- Adaptational Badass: While Gomora has always been pretty powerful, this one is far more so, even without his super modes. This includes introducing Gomora's Super Oscillatory Wave.
- Adaptational Heroism: The first heroic Gomora in the franchise and would appear also in some films fighting alongside the Ultramen.
- The Hero: Alongside Rei, he acts as this for the series, being the main monster and mascot-of-sorts.
- Horn Attack: The Super Oscillatory Wave, a huge blast of energy capable of vaporizing weaker monsters. It's essentially Gomora's answer to the Ultra's beam attacks.
- Lightning Bruiser: Is both fast and a massively strong monster, capable of going toe-to-toe with brutes such as Red King, Golza and even Zetton.
- Super Mode: EX Gomora
- Canon Immigrant: EX Gomora originally appeared in the Ultraman Fight Evolution video games.
- Superpowered Evil Side: Reionic Burst Gomora (until Rei learned to control himself).
Litra
- First Appearance: The Fifth Crewman
See Ultra Q
- Pint-Sized Powerhouse: Litra is still gigantic for a bird, but in comparison to all the other monsters in the series, she's virtually a sparrow. That doesn't stop her from earning some victories on her own or being a major ally for Gomora by keeping other kaiju distracted while he takes on the main one in any of the larger battles. She even managed to kill a Twin Tail solo.
- Playing with Fire: As Fire Litra, where she gains the ability to encase herself in fire and release the bird-shaped flames as a projectile.
- Super Mode: Fire Litra.
Eleking/Lim Eleking
- First Appearance: The Underwater King (Eleking)/The Pendragon Doesn't Rise to the Surface (Lim. Eleking)
See Ultraseven
- Adaptational Heroism: Like Gomora, this is Eleking's first heroic appearance (though it has remained his only one).
- Art Evolution: Compared to Eleking's previous reappearance in Ultraman Max, instead of using the updated suit from Max, the new Eleking is given a more "vintage" design closer to its debut in Ultraseven.
- Beware the Cute Ones: Eleking is surprisingly adorable for a kaiju, lacking claws, teeth, spikes or other visible weapons, and can even shape-shift into a chibi form of itself. But it's also extremely dangerous and powerful.
- Breath Weapon: Eleking gains the ability to breath a powerful bolt of lightning that functions similarly to the Super Oscillatory Wave in this series.
- Fun Size: Rei can call out Eleking in the form of Lim. Eleking, although how he does it is unexplained.
- Home Field Advantage: When ZAP Spacy is stranded underwater at the mercy of Zoa Muruchi, what does Rei do? Send out Eleking, another underwater-based monster with electrical powers, of course. The combined advantage gives Eleking an upper hand in the subsequent fight.
- Kill the Cutie: In Never Ending Odyssey, at the hands of Grande's Tyrant.
- Mythology Gag: Eleking is introduced as a lake-dwelling monster who make its introduction rising out the water's surface, like the first Eleking in Ultraseven.
- Slashed Throat: How Eleking dies, in the hands of Grande's Tyrant.
Miclas
After being freed from the Armoured Darkness, Ultraseven gave Rei his Miclas as a "thank you" gift. Miclas would battle alongside Gomora in several important battles.See Ultraseven
- Retcon: Despite being the original Miclas seen in Ultraseven, he displays the same Cowardly Lion personality of the Maquette Miclas used by GUYS in Ultraman Mebius rather than the braver and more confident attitude he had in his debut series.
Monsters and Aliens
Telesdon
- First Appearance: The Lawless Monster Planet
Telesdon also reappeared in NEO where it was the monster of Alien Zetton who used it to battle Alien Hook's Re-Dorako. Both monsters were killed by King Joe Black before their masters were eliminated as well.
See Ultraman TV Series
- Diurnal Nocturnal Animal: Despite being characterized as nocturnal in previous appearances, Telesedon is often above the ground in the day in this series.
- Mythology Gag:
- His battle against Sadorah homages Sadorah's debut in Return of Ultraman, in which Sadorah battles Detton, a kaiju created from an incredibly aged Telesdon suit.
- The battle with Re-Dorako in his NEO appearance references their battle in the original Ultraman when they are resurrected by Geronimon.
- Screw This, I'm Outta Here: Flees its battle with Red King, leaving Sadorah to get killed. However, it does return when Golza attacks ZAP SPACY to join forces with the stronger monster.
- Villain Team-Up: With Golza, and later Red King and Neronga.
Sadorah
- First Appearance: The Lawless Monster Planet
See Return of Ultraman
- Buttmonkey: Sadorah is literally the show's weakest Kaiju and solely exists to be pummeled effortlessly by Red King, Fire Golza, and other stronger monsters.
- Cannon Fodder: Compare to Buttmonkey as often it's a whole pack of Sadorahs that get massacred by stronger enemies, as well as human technology.
- The Worf Effect: Several Sadorahs are killed in under a minute by Fire Golza, for no reason other than to establish Golza as a threat.
- Zerg Rush: A Sadorah pack's main strategy. It never works for them.
Red King
- First Appearance: The Lawless Monster Planet
See Ultraman TV Series
- Curbstomp Battle: Completely tears Telesdon and Sadorah some new giant scaly rears by just barging into their battle to kill both combatants for the sake of it.
- Ultimate Showdown of Ultimate Destiny: His battle against Gomora one-on-one in the first episode is a dream come true for many Ultraman fans.
- Villain Team-Up: With Neronga and Telesdon when they were revived by Bullton to fight Gomora. However, Red King bosses the lesser monsters around and forces them to do the fighting for him.
Juran
- First Appearance: The Fifth Crewman
See Ultra Q
Golza
- First Appearance: The Fifth Crewman
See Ultraman Tiga
- Art Evolution: Golza's design in this series is a mixture of the original one from Ultraman Tiga and his reappearance in Ultraman Dyna.
- Guest Fighter: This marks the first appearance of a kaiju from Tiga-Dyna universe in the classic Showa universe.
- Villain Team-Up: With Telesdon.
Gudon
- First Appearance: The Transparent Monster Attacks!
See Return of Ultraman
- The Worf Effect: Its battle and defeat at the hands of Neronga quickly establishes how dangerous Neronga's invisibility powers would be for Gomora.
Neronga
- First Appearance: The Transparent Monster Attacks!
See Ultraman TV Series
- Forgot About His Powers: For some reason, Neronga never turns invisible in its second battle against Gomora.
- Glass Cannon: Dangerous enough to kill Gudon with a few lightning bolts even after almost being killed itself and almost defeats Gomora too, thanks to its invisibility technique, but is also weak enough to be killed instantly by an accidental hit from Telesdon's flame breath.
- Took a Level in Badass: In the original Ultraman, Neronga was one of Ultraman's weakest foes despite his powers, with all his attacks either not harming Ultraman at all or completely missing the hero. Here, Neronga becomes the first genuinely challenging opponent for Gomora (the first monster to defeat Ultraman), thanks to those same powers and manages to land some serious blows on him.
- Villain Team-Up: With Red King and Telesdon when the three are brought back by Bullton.
- Wake-Up Call Boss: Whereas Golza, Red King, and Telesdon are all straightforward melee foes for Gomora, Neronga's invisibility powers called for a more strategic approach to defeating it.
Bemstar
- First Appearance: Bemstar has Arrived!
Bemstar reappeared briefly in NEO where it attacks the Pendragon when ZAP SPACY encounters Dail, giving the team a chance to use the ship's new weapon, the Pedanium Launcher, against it.
See Return of Ultraman
- The Worf Effect: The second Bemstar's role is to be obliterated by the Pedanium launcher in seconds, proving the weapon's power and efficiency.
Banpira
- First Appearance: The Trap in Belargo City
See Ultraman Nexus
- Curb-Stomp Battle: Poor Banpira only lands a single hit on Gomora! It doesn't even use any of its previously established powers.
- Guest Fighter: The first Ultraman Nexus Space Beast to appear in the main Showa universe.
Fire Golza
- First Appearance: The Trap in Belargo City
See Ultraman Tiga
- The Brute: Fire Golza basically lets Gomora spray his Super Oscillatory Ray at him for an extended period of time and takes it without any injury, stress or effort, and everything Gomora throws at him is useless. Even after a repeated assault by ZAP SPACY and Gomora tries to destroy him from the inside out by stabbing his chest with his horn and firing the SOR, but he YANKS it out. He still survives and is only killed when his own ally accidentally shoots him, finally giving him enough punishment for the brute to expire.
- Decomposite Character: This time, Fire Golza is established as a separate creature from the classic Golza rather than the result of Golza absorbing magma to gain fire powers.
- One-Man Army: Golza is a One Kaiju Army, with an Establishing Character Moment where it debuts by wiping out a herd of Sadolas without breaking a sweat.
- Villain Team-Up: With Gan Q due to both being under Kate's control, which ends badly when Gan Q accidentally kills him with a misfired eye beam.
Gan Q
- First Appearance: The Trap in Belargo City
See Ultraman Gaia
- Art Evolution: In comparison to his original appearance, Gan Q's skin is closer to bare muscle and has less veins in his primary eye.
- Guest Fighter: The first monster from the Ultraman Gaia universe to appear in the Showa continuity.
- Lightning Bruiser: Although every bit as powerful as Fire Golza, Gan Q relies primarily on his Teleport Spam to overpower Gomora.
Twin Tail
- First Appearance: Another Monster Tamer
See Return of Ultraman
- David vs. Goliath: The Goliath to Litra's David.
Frogos
- First Appearance: The Stone That Calls Monsters
See Ultraman Nexus
- Ascended Extra: Frogos only appeared in a flashback very quickly in its original appearance. Here, Frogos is given fuller screentime and gets to do a little bit more. However, its still a rather brief appearance.
- Guest Fighter: Like Banpira, Frogos is originally from the Ultraman Nexus continuity.
- Your Size May Vary: Frogos is much larger in this series, standing at 40 meters tall, as opposed to the original's height of 10 meters.
Bullton
- First Appearance: The Stone That Calls Monsters
See Ultraman TV Series
- Art Evolution: It's portrayed by CGI rather than practical effects, and its antennae resemble organic tentacles instead of the inorganic, metallic Robot Antennae the original Bullton had. It also has a more muted colour scheme.
- Small Role, Big Impact: It only appears in one episode, but it's the reason why Bolis has so many kaiju and how Rei got there.
Kelbeam
- First Appearance: The Underwater King
Kelbeam was later seen in NEO as the second monster of Alien Guts, who Rei challenged with his newly-gained Miclas.
See Ultraman Mebius
- Ironic Echo: The battle (and subsequent defeat by) with Earthtron references their reluctant teamup in Ultraman Mebius, where Kelbeam had managed to mind control Earthtron and bully the lesser kaiju into battling Mebius for it.
- Mythology Gag: Alongside from the Earthtron case, Kelbeam's battle with Miclas in NEO is an homage to the fourth episode of Ultraman Mebius, where Miclas is used by GUYS to battle Kelbeam, only to find that Miclas needs encouragement to battle other kaiju, which is also what Rei learns when he uses Miclas against Guts' Kelbeam.
Earthtron
- First Appearance: The Underwater King
Earthtron reappeared in NEO as the monster of Alien Zelan. Unfortunately for the two, Alien Nackle's Galberos was too powerful for them and Earthtron was destroyed with its master.
See Return of Ultraman
Angross
- First Appearance: The Pendragon Doesn't Rise to the Surface
See Ultraman Mebius
- We Hardly Knew Ye: Only have a few minutes of screentime before getting killed off alongside Gromite by King Joe Black.
Gromite
- First Appearance: The Pendragon Doesn't Rise to the Surface
See Ultraman Mebius
- We Hardly Knew Ye: Only have a few minutes of screentime before getting killed off alongside Angross by King Joe Black.
Arigera
- First Appearance: The Pendragon Doesn't Rise to the Surface
Arigera briefly returned in NEO where Alien Temperor had used the monster to defeat Alien Mefilas. However, Mefilas returned as Armoured Mefilas and slew both monster and master.
See Ultraman Mebius
- Killed Offscreen: It is implied that the entire flock of Arigera that attacked Zap Spacy while underwater are all killed when the whole planet goes kaboom in the final episode.
Zoa Muruchi
- First Appearance: The Pendragon Doesn't Rise to the Surface
A sea monster attracted by the high-frequency waves ZAP SPACY had used to chase off the Arigeras, threatening to destroy the Pendragon. Rei sent out Eleking to battle it.
See Return of Ultraman
Nova
- First Appearance: Unexpected Reunion
See Ultraman Leo
- Curb-Stomp Battle: Nova misses the only hit it throws at Gomora and then dies instantly afterwards!
- Villain Team-Up: With Lunatyx and Salamandoras.
Lunatyx
- First Appearance: Unexpected Reunion
See Ultraman Ace
- Diabolus ex Nihilo: A monster which is a Choju, but somehow not affiliated with Yapool, appearing from out of nowhere to attack the good guys. This case is especially strange since unlike Velokron and Doragory, Lunatyx isn't seen with another Choju and is instead working alongside two standard kaiju. Presumably, Bullton's monster summoning had something to do with it.
- Villain Team-Up: With Nova and Salamandoras.
Salamandoras
- First Appearance: Unexpected Reunion
See Ultraman 80
- Villain Team-Up: With Lunatyx and Nova.
King Joe Black
- First Appearance: Unexpected Reunion (Appears in spaceships form in "The Pendragon Doesn't Rise to the Surface")
In NEO, the Pedans construct an entire army of King Joe Blacks to slaughter every Reionics in the universe. With the Reionics all congregating at the planet Hammer, the King Joe Blacks were sent in. However, Rei and Grande prove to be major wrenches in the Pedans' plans.
See Ultraseven
- Arm Cannon: Unlike the original King Joe, although this trait would be used in some other incarnations of King Joe.
- Conservation of Ninjutsu: Despite a single one being able to completely curbstomp Gomora, Litra, and Eleking's combined strength without even flinching, an entire army of them are easily pummeled by Gomora and Miclas in NEO.
- Elite Mook: Of an already formidable monster.
- The Juggernaut: Even more so than the original King Joe. Gomora, Eleking, and Litra could barely even scratch this guy! Even when EX Gomora manages to impale a hole in its body, the damn thing is still able to come back and tries to destroy the Pendragon while they are escaping Bolis' destruction, with only the timely arrival of Ultraman being able to finally stop King Joe Black by hurling it into the planet's collision with its artificial sun!
- Mecha-Mooks: Of the Pedans in NEO.
- Taking You with Me: It appears to be destroyed, but the first King Joe Black makes a comeback trying to stop ZAP Spacy from leaving Planet Bolis' Earth-Shattering Kaboom, dragging the heroes with it to destruction. It takes Ultraman's arrival for the ZAP Spacy to escape.
- Torso with a View: The first King Joe Black gets a hole ripped through its midsection thanks to Gomora's tail, but it's not enough to take it down.
- The Worf Effect: Delivers one in the form of its beatdown on Gomora, Eleking, and Litra, and then becomes a victim of it when it battles Grande's Red King in NEO.
Velokron
- First Appearance: Ultraman
See Ultraman Ace
- Diabolus ex Nihilo: A monster which is a Choju, but somehow not affiliated with Yapool, appearing from out of nowhere to attack the good guys. Given that it's established the numerous kaiju on Bolis were the result of Bullton resurrecting them, it's likely Bullton had more to do with this than Yapool did.
Doragory
- First Appearance: Ultraman
Doragory returned in NEO as one of the monsters of Alien Metron. Metron unleashed the Choju upon Rei, but Gomora mercilessly pummeled his adversary, forcing Metron to call Doragory back and flee.
See Ultraman Ace
- Diabolus ex Nihilo: A monster which is a Choju, but somehow not affiliated with Yapool, appearing from out of nowhere to attack the good guys. Given that it's established the numerous kaiju on Bolis were the result of Bullton resurrecting them, it's likely Bullton had more to do with this than Yapool did.
Zetton
- First Appearance: Ultraman
See Ultraman TV Series
- The Juggernaut: As usual for Zetton, he is one of the only monsters in the entire series to take on a King Joe Black alone and match it blow for blow.
- Lightning Bruiser: This Zetton is extremely agile compared to other incarnations of the kaiju, being able to perform backflips and flying kicks with ease while still strong enough to face all of Rei's monsters at once.
Magular
- First Appearance: Reionics Hunter
See Ultraman TV Series
Gomess
- First Appearance: Reionics Hunter
See Ultra Q
Alien Guts
- First Appearance: Reionics BattleVoiced by: Naoki Tatsuta
See Ultraseven
Dorako
- First Appearance: Reionics Battle
See Ultraman TV Series
- Back from the Dead: Although how is unexplained. It could just have been that Hook had two Dorakos.
- Clip Its Wings: The first Dorako suffers this fate when Eleking pulls off it's wings.
- Mythology Gag: The revived Dorako's battle against Telesdon is a homage to a scene from the original Ultraman where the two monsters are battling each other in the dead of night.
Alien Hook
- First Appearance: Reionics BattleVoiced by: Eikei Iwata
See Ultraseven
Alien Zelan
- First Appearance: Great Frenzy! Reionics BurstVoiced by: Kiyoshi Okazaki
See Return of Ultraman
- The Worf Effect: Gets eliminated by Nackle's Galberos to prove how tough the monster is.
Alien Nackle
- First Appearance: Great Frenzy! Reionics BurstVoiced by: Michio Nakao
See Return of Ultraman
- Elite Mook: More cunning and ruthless than the previous Reionics.
- Oh, Crap!: Lets out a pretty epic one when his Galberos gets eliminated. And then Gomora decides to finish off Nackle before he leaves, for good measure.
Galberos
- First Appearance: Great Frenzy! Reionics Burst
See Ultraman Nexus
- Guest Fighter: The first appearance of Galberos in the Showa timeline, having originally been from the Ultraman Nexus universe.
Alien Babarue "RB"
- First Appearance: Disturbing ReunionVoiced by: Isamu Sugaya
Many years later he would finally return to the franchise, having been a petty thief ever since the end of the Reionics War and now calling himself RB, he is caught by Andro Melos and subsequently offered mercy by being given a position in the Galaxy Rescue Force. See Galaxy Rescue Force Voice Dramas for his appearance in the Voice Drama.
See Ultraman Leo
- Screw This, I'm Outta Here: His response after realizing he's no match for Rei and Gomora.
- What Happened to the Mouse?: Flees after realizing Antlar is no match for Gomora. Never returned for the rest of the series. The Mega Monster Battle: Ultra Adventure NEO manga shows that he had a run in with the manga's main characters who managed to kill Antlar, but he was able to teleport away when Reionics Hunters arrived on the scene. Never to be seen again for a long time until 2021 in which he appears in the Galaxy Rescue Force Voice Drama and becoming the team's newest member.
Antlar
- First Appearance: Disturbing Reunion
See Ultraman TV Series
- What Happened to the Mouse?: Was never seen again in the series after getting pummeled by Gomora and recalled by Babalou. The Mega Monster Battle: Ultra Adventure NEO manga shows that it got killed by Kanegon's Red King due its injuries from its fight against Gomora.
Alien Metron
- First Appearance: Disturbing ReunionVoiced by: Osamu Ryutani
See Ultraseven
- Determined Defeatist: Despite getting his ass kicked by Rei's Gomora and realizing his monsters are no match for Rei, he relentlessly pursues Rei for another battle.
- Mythology Gag: His usage of Doragory homages how Doragory teamed up with an Alien Metron in his debut in Ultraman Ace.
Vakishim
- First Appearance: At the End of the Runway
See Ultraman Ace
Tyrant
- First Appearance: The Strongest Reionics
See Ultraman Taro
- The Juggernaut: As usual for the infamous Chimera Kaiju, it takes teamwork between Litra and Gomora to finally take him down and avenge Eleking.
- Slashed Throat: Does this to poor Eleking...
Alien Zarab
- First Appearance: Shoot the Infiltrator!Voiced by: Takeshi Aono
This individual Zarab returns in Mega Monster Battle: Ultra Galaxy Legends (or at least implied to be the same one) where he has gotten his hands on the Giga-Battle Nizer (as seen in the stinger of Ultraman Mebius Gaiden: Ghost Reverse). Using his Ultra disguise, he infiltrates the prison of Ultraman Belial and frees the dark warrior. Belial kills him quickly afterwards and takes the Giga-Battle Nizer, starting the Land of Light's greatest crisis yet.
See Ultraman TV Series
- Adaptational Comic Relief: This Zarab is a Butt-Monkey and a bumbling villain featured in a Breather Episode who poses no threat to our protagonists. Even when freeing Belial, he gets instantly killed the moment Belial gets his weapon back.
- Bare-Handed Blade Block: Tries to do this to Gomora's tail. Emphasis on tries.
- Harmless Villain: That is until he frees Ultraman Belial. Too bad for him he was biting more than he could chew by trying to ally with Belial.
- Too Dumb to Live: Perhaps you should have made the offer of ruling together to Belial BEFORE giving him his super-weapon... Or just not hand it over at all.
Armoured Mefilas
- First Appearance: Armour of DarknessVoiced by: Seizō Katō
See Ultraman TV Series
- Back from the Dead: After Armoured Darkness kills him and takes its sword back, Mefilas is resurrected by Alien Reiblood as a mindless giant to fight Gomora and Miclas.
- Cool Sword: Wields one as Armored Mefilas.
- From Nobody to Nightmare: From a bumbling Reionics that everybody made fun of to one of the deadliest killers on the planet and perfectly capable of going toe-to-toe with even the mightiest Reionics monsters.
Dada
- First Appearance: Armour of DarknessVoiced by: Michitaka Kobayashi
See Ultraman TV Series
- Bullying a Dragon: Essentially what costs Dada his life.
- We Hardly Knew Ye: He'll regret gloating in front of Mefilas for the rest of his life. All five seconds of it.
Alien Temperor
- First Appearance: Armour of DarknessVoiced by: Daisuke Gōri
See Ultraman Taro
- Asshole Victim: But of course.
- Karmic Death: While Mefilas wasn't a saint by any means, Temperor went far beyond necessary at leaving him for dead, thus making his death karmic retribution.
Armoured Darkness
- First Appearance: Armour of Darkness
See Ultraman Mebius
Alien Zetton
- First Appearance: The New Horizon of WarVoiced by: Hiroshi Suenaga
See Ultraman TV Series
- All There in the Manual: According to supplementary material, he has 2 other unseen monsters, one of them being a Zetton.
Grande's Red King
- First Appearance: The New Horizon of War
See Ultraman TV Series
- Playing with Fire: This version of Red King has the ability to encase his fists in flame to enhance his punches.
- Power Fist: A new ability granted to future EX Red King incarnations, Red King can now expand its fists into gigantic, battering ram-like appendages for pummeling their targets.
- The Rival: To Gomora in the same vein as Grande and Rei.
- Super Mode: EX Red King.
- Canon Immigrant: EX Red King originally appeared in the Ultraman Fight Evolution video games alongside EX Gomora.
- Took a Level in Badass: In comparison to the Red King encountered in Mega Monster Battle and previous ones as well, this Red King is far smarter and stronger than most, capable of tearing a King Joe Black easily.
King Joe Scarlet
- First Appearance: The New Horizon of War
See Ultraseven
- Unique Enemy: The one and only Scarlet variation of King Joe to appear in the entire franchise.
Alien Reflect
- First Appearance: Grande's ChallengeVoiced by: Hirohiko Kakegawa
See Ultraman Mebius
- What Happened to the Mouse?: Like Babalou, he is completely forgotten after Birdon is killed and his fate is left unanswered.
Birdon
- First Appearance: Grande's Challenge
See Ultraman Taro
Villains
Alien Reiblood
- Voiced by: Masaharu Sato
- Ancient Evil: Likely the most ancient evil entity in the "Land of Light" universe, having existed long before the Ultras (and presumably Alien Empera, the other Greater-Scope Villain of the Ultra Series) ever came into being.
- Big Bad: Of NEO. He's the one who's manipulating all the Reionics to fight each other to the death so that the winner will become the new Reiblood AKA a suitable body for him to inhabit so he can restart his rule of the Universe.
- The Chessmaster: Manipulated the events of the series in order to bring about his chosen successor.
- The Dreaded: Reiblood was so powerful and deadly that even Yapool and the cruel Hipporit Aliens feared him.
- Humanoid Abomination: While his "Alien" title makes it seem he's one of a species, his presentation indicates he's a lot more than that, most notably is his incredible resilience in spirit form and eldritch powers and influence.
- Galactic Conqueror: Ruled the entire universe eons ago.
- Greater-Scope Villain:
- Of Ultra Galaxy Mega Monster Battle, as he's responsible for the existence of the Reionics and thus both Rei and Kate as well.
- To the Ultraman Zero film trilogy and spin-offs and Ultraman Geed. He doesn't act directly on those series, but his actions in the past and Deal with the Devil he gave to Belial to empower the latter are directly responsible for everything that went wrong. He's also indirectly responsible for the events of Ultraman Z, as parts of Belial's body lost throughout his fights that are imbued with Belial's (And by extension, Reiblood's) evil became the Devil Splinters.
- The Man Behind the Man: To Ultraman Belial, although the degree to which depends on if Reiblood only empowered him or was driving his actions at all. The finale of Geed has Reiblood being purged from Belial's body, seeming to imply he still had some influence beyond just bestowing him with power.
- Monster Lord: He commanded all kaiju before his body dissipated. This ability is inherited by the Reionics.
- Monster Progenitor: All of the Reionics were birthed from his genes.
- Spell My Name With An S: Also known as Rayblood, Reibrad, or Raybrad.
- Time Abyss: This guy existed before the Ultramen did and has been around longer than every other villain in the Ultra Series. Yeah. The only entity that may even come close is Ultraman King.
- Ultimate Life Form: His subtitle refers to him as such. Given his power and the fact that he once ruled over the universe, this likely isn't far off.
- Uncertain Doom: His body was destroyed long ago, scattering his genes and resulting in the Reionics emerging, but the exact circumstances of how this came about aren't elaborated on.
- Walking Spoiler: His influence is there from the beginning, but his role and identity isn't reveal until much later.
- Xanatos Gambit: Turns out the Reionics fight was this as no matter who won it, good or evil, the ultimate goal of the battle was to create a suitable host for Reiblood to possess and use as a vessel to restart his rule of the universe, Rei only barely averts this fate thanks to his indomitable will and help from Ultraman and Ultraseven.
Kate
- Played by: Mayu Gamo
- Bad Boss: She ordered her Gan Q to kill her Fire Golza after it failed to defeat Rei's Gomora.
- Big Bad: She is the main antagonist of the first season of Ultra Galaxy Mega Monster Battle.
- Cain and Abel: Subverted. While she opposes Rei all throughout the season, her true goal is to awaken his Reionics powers.
- Dark Action Girl: Fully willing to put herself in the heat of battle.
- Knight Templar Big Sister: Turns out to be this to Rei. As villainous as she is, everything she did was to guide her baby brother into becoming the next Lord of the Reionics.
- Luke, I Am Your Father: Reveals herself as Rei's biological sister near the finale of the first season.
- Ms. Exposition: Reveals a lot of details about the Reionics in high detail.
- The Rival: To Rei. Or at least what she acted like.
- Samus Is a Girl: When she first appears and makes contact with Rei, her voice is distorted and slightly masculine.
- Sensible Heroes, Skimpy Villains: In contrast to Rei's professional uniform, her outfit has Stripperiffic written all over it.
- Sink or Swim Mentor: What she was all along, she was preparing Rei to become the next Lord of the Reionics and Monsters of the Universe.
- Strong and Skilled: Her monsters are stronger and more experienced in combat than Rei's.
- Walking Spoiler: Her revelations about the Reionics in the last episode turn her into this.
Alien Pedan Dail
- Played by: Kosei Kato
See the Ultraseven character sheet for tropes applying to the Alien Pedan in general
- Anti-Hero: He's one of the best Reiyonix Hunters and assassins out there, but he's firmly one of the good guys.
- Blood Knight: He's unfazed at demonstrating the Pedanian Launcher's powers to a horrified ZAP SPACY, using it to utterly obliterate a stray Bemstar.
- Casting Gag: Kosei Kato was previously known for his role as Mitsuhiko Hirukawa from Ultraman Mebius, a massive Dirty Coward Hate Sink who sells out the humans and exposes Ultraman Mebius' human identity in public, all to save his own skin. Come by this series, he's a heroic alien who eventually turncoats to help the humans by the end.
- The Dragon: Initially serves this role to the Pedan's Queen, Harlan, but he eventually turncoats.
- Heel–Face Turn: The one Alien Pedan who eventually turns on his own kind and defects to the side of humans. He even supplies ZAP SPACY with the Pedanium Cannon, a superweapon belonging to their race, which proves useful to the humans later in the series.
