    ZAP SPACY (Zata Astronomical Pioneers Spacy) 

Played by: Shota Minami
The hero of the story. Rei is an amnesiac orphan first encountered by the ZAP SPACY delivery crew while on a mission to the planet Bolis. The only thing he can remember about himself is that he is destined for never-ending battle against kaiju, but with the help of the team, he learns more about himself. He can call forth his monsters, Gomora, Litra, and Eleking, by using a tool called a Battlenizer, which he has had with him for as long as he can remember.

Hiroshi Hyuga
Played by: Hiroyuki Konishi
The leader of the ZAP SPACY crew aboard the Pendragon. Known by his crew as "Boss", Captain Hyuga is well versed with the hazards of intergalactic travel and excels in martial arts. He serves as a sort of father figure to Rei.

Jun Haruna
Played by: Saki Kamiryo
Second-in-command aboard the Pendragon and sole female member of the team, Haruna is a no-nonsense ace pilot loyal to Captain Hyuga. She is skeptical towards Rei initially, but soon becomes his closest friend on the team.

Koichi Oki
Played by: Toru Hachinohe
A relatively inexperienced member of the crew, Oki is a colossal monster maniac (he majored in kaijuology) who knows everything about giant monsters and the history of Ultramen on Earth.

Masahiko Kumano
Played by: Mitsutoshi Shundo
Hyuga and the Pendragon's longest-serving crew member. Kumano is the ship's engineer nicknamed "Wizard" by his teammates for his proficiency with the Pendragon and her mechanics.

    Rei's Monsters 


Reionic Burst Gomora 
EX Gomora 

First Appearance: The Lawless Monster Planet
Rei's first monster and primary choice for battle. This is the first heroic appearance of Gomora (or any other monsters previously fought by the Ultramen), as well as the debut of Gomora's Super Oscillatory Wave.
See Ultraman
  • Adaptational Heroism: The first heroic Gomora in the franchise and would appear also in some films fighting alongside the Ultramen.
  • Horn Attack: The Super Oscillatory Wave, a huge blast of energy capable of vaporzing weaker monsters. It's essentially Gomora's answer to the Ultra's beam attacks.
  • 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).


First Appearance: The Fifth Crewman
Rei's second monster. Rei captured Litra after she defeated the giant flower Juran. Possesses the ability to transform into Fire Litra and has proven to be a valuable ally for Gomora and ZAP SPACY in many battles.
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 take son the main one in any of the larger battles.
  • 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)
Rei's third monster, which originally appeared as a threat to ZAP SPACY when they trespassed the lake it lived in. After Gomora defeated it, Rei added it to his Battlenizer and would use it in many battles to come.
See Ultraseven
  • Adaptational Heroism: Like Gomora, this is Eleking's first heroic appearance (though it has remained his only one).
  • Breath Weapon: Eleking gains the ability to breath a powerful bolt of lightning that functions similarly to the Super Oscillatory Wave in this series.


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


    Monsters and Aliens (First Appearing in Mega Monster Battle) 


First Appearance: The Lawless Monster Planet
The first monster ZAP SPACY encounters when they land on Bolis, where they witness it battle Sadorah and Red King. It later appears alongside Golza to battle Gomora, and then alongside Red King and Neronga when the three are resurrected by Bullton.

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
  • 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.
  • Villain Team-Up: With Golza, and later Red King and Neronga.


First Appearance: The Lawless Monster Planet
The most common kaiju amongst the rampaging hordes of monsters on Bolis, as they travel in groups. A stray one battles Telesdon and Red King when ZAP SPACY arrives in Bolis. Later, a pack of 8 Sadorahs were destroyed by Kate's Fire Golza, and a pack of 5 Sadorahs would attack the Pendragon while Rei's Gomora fought Kate's Gan Q.
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.
  • Zerg Rush: A Sadorah pack's main strategy. It never works for them.

Red King

First Appearance: The Lawless Monster Planet
The third kaiju encountered by ZAP SPAY when they arrived on Bolis, where they witnessed it brutally pummel Telesdon and Sadorah. It then turned its attention to ZAP SPACY and would end up battling Rei's Gomora. Red King later returned when the reality-warping meteor Bullton summoned him along with Telesdon and Neronga to all fight Gomora again. Red King bossed the lesser monsters, forcing them to do the fighting for him.
See Ultraman
  • 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.


First Appearance: The Fifth Crewman
A mammoth flower that burts from the ground and attacks Hyuga and Oki while they are searching for Rei. It battles Litra.
See Ultra Q


First Appearance: The Fifth Crewman
A monster that attacks ZAP SPACY when the crew is searching for Rei, which is made worse for the humans when Telesdon joined the assault. The two then battle Gomora and Litra when Rei appears to save ZAP SPACY.
See Ultraman Tiga


First Appearance: The Transparent Monster Attacks!
A kaiju that battles Neronga.
See Return of Ultraman


First Appearance: The Transparent Monster Attacks!
Gudon's opponent who then turns its attention to ZAP SPACY by consuming the Pendragon's electricity, crippling the ship and forcing Rei to call forth Gomora, who would be seriously challenged by its invisibility. Later, Bullton called in Neronga with Red King and Telesdon to fight Gomora.
See Ultraman
  • 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.
  • 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.


First Appearance: Bemstar has Arrived!
A monster that attacks ZAP SPACY when they enter the ruined capital of planet's colonies, Belargo City. Rei called forth Gomora and Litra to fight it, but the space monster's ability to simply eat their energy attacks posed a great challenge.

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


First Appearance: The Trap in Belargo City
An arachnid Space Beast that attacks Oki and Rei while they are searching the ruins of Belargo City for survivors. Rei called forth Gomora to fight the spider-like kaiju.
See Ultraman Nexus

Fire Golza

First Appearance: The Trap in Belargo City
Kate's first monster and a stronger version of the Golza that ZAP SPACY had encountered earlier. It proves to be Gomora's most powerful foe so far, especially when Kate sends out Gan Q to assist it.
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 the gain fire powers.
  • Villain Team-Up: With Gan Q, until Gan Q accidentally kills him with a misfired eye beam.

Gan Q

First Appearance: The Trap in Belargo City
Kate's second monster.
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
A monster that ambushes Rei while he is strolling about Bolis by himself. It battles Litra, but as the bird monster is too small to be an even match for Twin Tail, Rei delivers some assistance with his ZAP SPACY firearms.
See Return of Ultraman


First Appearance: The Stone That Calls Monsters
An amphibian-like Space Beast that attacks Rei and Hyuga while they are exploring Belargo City. Rei uses Litra to battle it.
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. However, Frogos is much larger in this series, standing at 40 meters, as opposed to the original's 10.


First Appearance: The Stone That Calls Monsters
When the human colonists of Bolis discovered a pair of meteors with reality warping powers, Bullton was born from the two space rocks merging together. The creature's reality-warping powers destroyed the planet's settlements by filling it with hordes of kaiju. When ZAP SPACY entered its lair in Belargo City, Bullton retaliated by calling in various monsters to destroy the intruders.
See Ultraman


First Appearance: The Underwater King
One of two monsters seen battling each other besides the lake where Eleking dwelt.

Kelbeam was later seen in NEO as the second monster of Alien Guts, who Rei challenged with his newly-gained Miclas.

See Ultraman Mebius


First Appearance: The Underwater King
The second of two monsters that battle each other at a lakeside. After killing Kelbeam, Earthtron is suddenly dragged into the lake by Eleking's tail. Out of its environment, Earthtron is quickly killed by Eleking just in time for ZAP SPACY to bear witness to.

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


First Appearance: The Pendragon Doesn't Rise to the Surface
Like any other day on Bolis, two kaiju were dueling to the death. The first was the jackhammer-nosed Angross and the other was the rocky Gromite. The two monsters were equally matched, but before either could continue, several black spaceships arrived and killed Angross.
See Ultraman Mebius


First Appearance: The Pendragon Doesn't Rise to the Surface
Starting the day off with a battle against Angross, Gromite's clash was interrupted by the arrival of four spaceships that instantly killed both combatants.
See Ultraman Mebius


First Appearance: The Pendragon Doesn't Rise to the Surface
When the Pendragon was driven to the bottom of the sea and damaged by four black spaceships, ZAP SPACY had to deal with a school of these supersonic monsters. They repelled the monsters through the usage of high-frequency waves to drive them in the other direction. However, worse was yet to come.

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

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


First Appearance: Unexpected Reunion

See Ultraman Leo


First Appearance: Unexpected Reunion
The second of the three monsters at the supply depot where they battled Gomora. It is destroyed instantly by the same fleet of black spaceships that attacked the Pendragon and killed Angross and Gromite.
See Ultraman Ace


First Appearance: Unexpected Reunion
The third monster at the supply depot. It is destroyed alongside Lunatyx by the spaceships, which reveal themselves to be the separated form of King Joe Black.
See Ultraman 80

King Joe Black

First Appearance: Unexpected Reunion (Appears in spaceships form in "The Pendragon Doesn't Rise to the Surface")
A modified version of King Joe sent by the Alien Pedans to destroy Rei, Kate, and their monsters. It comes to Bolis in the form of four black spaceships and proceeds to annihilate every monster that it encounters during its search. For the remainder of Mega Monster Battle, it proves a serious menace to ZAP SPACY's plans to evacuate survivors off the planet and proves to be a nigh-unstoppable foe for Rei's monsters and Kate's Zetton.

In NEO, the Pedans construct an entire army of King Joe Blacks to slaughter every Reionyx in the universe. With the Reionyxes 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.
  • 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.


First Appearance: Ultraman
A Choju that attacks ZAP SPACY and the Bolis survivors as they prepare to leave the planet. Rei uses Gomora to battle it.
See Ultraman Ace


First Appearance: Ultraman
Another Choju that appears alongside Velokron. Rei summons Eleking to defeat it.

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


First Appearance: Ultraman
Kate's third and final monster, which she uses against the combined strength of Gomora, Litra, and Eleking. Later on, she sends it out to battle both Rei's Gomora and King Joe Black when Bolis is about to be destroyed by its artificial sun and giving Rei his first taste of a true Reionyx battle, where the loser dies with their monsters and feels all the blows the monster takes.
See Ultraman

    Monsters and Aliens (First Appearing in Never Ending Odyssey) 


First Appearance: Reionyx Hunter
A wild kaiju that attacks Rei's Gomora and Aliens Guts' Gomess when Rei and Hyuga are stranded on the planet Hammmer, creating a sort of three-way battle.

See Ultra Q

First Appearance: Reionyx Battle
Alien Hook's monster of choice, Dorako was sent to destroy the Dragon Coaster like Guts had tried with Gomess. Rei sent Eleking to fight them. Later on, Hook somehow brings back the monster as Re-Dorako, now without its wings and hook hands, and uses it against Alien Zetton's Telesdon. The two monsters are killed by King Joe Black and he masters followed their fates soon afterwards.
See Ultraman
  • Back from the Dead: Although how is unexplained. It could just have been that Hook had two Dorakos.
  • Mythology Gag: Re-Dorako's battle against Telesedon 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: Reionyx Battle
Voiced by: Eikei Iwata
A Reionyx in control of the savage Dorako. He unleashes his monster partner upon the Dragon Coaster. Later on, he battles Alien Zetton's Telesdon with his resurrected Dorako until both kaiju were killed by King Joe Black.

First Appearance: Great Frenzy! Reionyx Burst
Voiced by: Kiyoshi Okazaki
A Reionyx who commands the unbridled ferocity of Earthtron. He goes up against the Galberos of Alien Nackle. Unfortunately for Zelan, Earthtron was destroyed easily by Galberos, and both master and monster perished in a fiery explosion.
See Return of Ultraman

Alien Nackle

First Appearance: Great Frenzy! Reionyx Burst
Voiced by: Michio Nakao
A sadistic Reionyx with mastery over the three-headed Space Beast known as Galberos. After annihilating Zelan and his Earthtron, Nackle sends his monster after Rei and Gomora, draining their strength and patience with Galberos' illusions. However, the wicked scheme would end up unlocking Rei's nigh-uncontrollable Reionic Burst Mode.
See Return of Ultraman


First Appearance: Great Frenzy! Reionyx Burst
A savage Space Beast utilized by Alien Nackle, Galberos was unleashed upon Gomora and Rei by tormenting them with an immortal illusion of Zetton. Once Nackle decided Gomora was ripe for an easy kill, Galberos would drop the illusions and head in, only to discover the power of Reionic Burst Mode.
See Ultraman Nexus

Alien Babalou

First Appearance: Disturbing Reunion
Voiced by: Isamu Sugaya
A Reionyx with the juggernaut known as Antlar as his monster of choice. He attacks Captain Hyuga while the human was searching for Rei (who had been on a rampage since entering Reionic Burst Mode for the first time) by siccing Antlar on him.
See Ultraman Leo


First Appearance: Disturbing Reunion
Bablou's companion, Antlar was unleashed by the vile alien to kill Captain Hyuga for his entertainment. The brutish insect would have succeeded, but Rei and Gomora (both in Reionic Burst Mode) entered the scene and battled monster and master.
See Ultraman

Alien Metron

First Appearance: Disturbing Reunion
Voiced by: Osamu Ryutani

Alien Zarab

First Appearance: Shoot the Infiltrator!
Voiced by: Takeshi Aono
Unlike all the Zarabs before him, this one is a comical simpleton who has made a life out of stealing Battlenizers for unexplained reasons. He came to Hammer for the Battlenizer motherload and got his hands on many before targeting Rei and ZAP SPACY.

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-Battlenizer (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-Battlenizer, starting the Land of Light's greatest crisis yet.

See Ultraman

Armoured Mefilas
First Appearance: Armour of Darkness
Voiced by: Seizo Kato
The most pathetic of all the Reionyx warriors. After being curbstomped by Alien Temperor, his battlenizer was destroyed and he was left to die. The frustrated alien finds a mysterious sword and upon holding it, gained a suit of armour that mind controlled the former Reionyx and sent him on a rampage.
See Ultraman
  • 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.
  • From Nobody to Nightmare: From a bumbling Reionyx to one of the deadliest killers on the planet.


First Appearance: Armour of Darkness
Voiced by: Michitaka Kobayashi
Also a Reionyx, Dada was, like Alien Temperor, a rival to Alien Mefilas back when he was an incompetent Reionyx. Dada bumped into the now Armoured Mefilas and ridiculed the former Reionyx. He didn't live to regret it as Mefilas slew the fool for his words.
See Ultraman

Alien Temperor

First Appearance: Armour of Darkness
Voiced by: Daisuke Gori
A dastardly Reionyx who uses the supersonic Arigera. Having defeated the bumbling Mefilas Reionyx, he destroyed his foe's Battlenizer and left him to wallow in humiliation. However, when Mefilas became Armoured Mefilas, Temperor would feel the bite of vengeance when Mefilas killed him with his newly-gained sword and armour.
See Ultraman Taro

Armoured Darkness

First Appearance: Armour of Darkness
A wicked suit of animated armour used as the personal enforcer of the mysterious forces that had called the Reionyxes from across the universe to Hammer. Mefilas was transformed into Armoured Mefilas when discovered the monster's sword and the monster would later battle Gomora and Red King.

See Ultraman

Grande's Red King

EX Red King 
First Appearance: The New Horizon of War
A more powerful version of Red King used by Grande. It first appears to battle a King Joe Black sent by the Reionyx Hunters to kill Grande. Later, Grande unleashes his monster against Rei's Gomora for a final showdown between rivals and would then call him forth one more time to assist Gomora against Armoured Darkness.

  • 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.

Alien Reiblood


Voiced by: Masaharu Sato
The progenitor of all Reionyxes and the true villain of the series. Reiblood is an immensely powerful being who terrorized the universe before the Ultramen even existed. However, his body was destroyed long ago, dissipating his essence across the cosmos to create the Reionyxes. His spirit still lives on though, and has called the Reionyxes to Hammer to choose a successor from them.
  • Big Bad: Of this series. He's the one who's manipulating all the Reionyxes to fight each other to the death so that the winner will become the new Reiblood.
  • 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.
  • Monster Lord: He commanded all kaiju before his body dissipated. This ability is inherited by the Reionyxes.
  • 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.
  • Walking Spoiler: His influence is there from the beginning, but his role and identity isn't reveal until much later.
