"(First Monster Name)! (Second Monster Name)! This is the End Mark!"

―Kei's catchphrase when transforming into Belial Fusion Monsters

"All goes well, my lord...master Belial. The power that you bless me with...will allow me to Fusion Rise once again. It's time to deal with the interloper."

―Kei as he met Belial.

Kei Fukuide (伏井出 ケイ Fukuide Kei) was one of the main antagonists in Ultraman Geed. An Alien Sturm servant to Ultraman Belial, he posed as a famous sci-fi writer who masks his cruel and ruthless side under a polite and gentle behavior.


Not much is known of Kei before joining Belial, but he himself states that he was lost and without purpose until joining his master. Kei is very loyal and devoted to Belial, giving up everything for the Dark Ultra, even his own life, to see his plans come to fruition. In fact, his loyalty goes to the extent where he became devoid of other emotions beside it at his core, even if it's evident that Belial was only using him. While disguising as a human, Kei is shown to have a charismatic side as well, presenting himself as such in public.

He also has a cunning and ruthless side as well, as he was willing to use tricks, kidnapping and ransom to advance with his plans, murdering those who stood in his way. Kei is also willing to backstab anyone who interferes with his plans or when their use has run out.

Kei views Geed and Zero as mere pests in the grand order of things, and furthermore sees the former as nothing but a tool who is unworthy of Belial's genes, despite being his very own creation. His resentments towards Geed prevents him from seeing the extent of Geed's strength and development as a hero and his own person he ironically arranged from behind the scenes, resulting his recurring defeat at hands of the young Ultra Warrior.


Pre-Ultraman Geed

Kei Fukuide was previously an Alien Sturm who lacks a purpose (even referring himself as an empty shell) until his encounter with Belial changed his life. Since then he pledged his loyalty to the dark Ultra and helped him with his conquest over the universe. Kei was one of the participants of the Omega Armageddon alongside Belial, the Darkness Five and Belial's new army, called Terror The Belial against the Ultra Warriors in a heated battle which held the universe fate at stake.

In aftermath of the Crisis Impact, Kei broke into the Land of Light and stole Hikari's Ultra Capsules. Aside from the creation of Riku Asakura (through Belial's DNA sample), Kei spread the Carellen element to attract Childhood Radiation and merged them to Earth life forms as Little Stars.

Kei targeted the first Little Star in the form of Laiha Toba by attacking Mt. Mitsuse as Skull Gomora which led to her parent’s death. However her fear revoked her abilities and the Little Star faded away.

Ultraman Geed

Six years later, he transformed into the same monster and attacked Hoshiyama thrice, targeting Eri Hara's Little Star before Ultraman Geed appeared for the first time and defeated him. Seeing Geed's involvement, Kei decided to make the Ultra part of his own plans onward, orchestrating or observing monster attacks from behind the scene as Riku harvested the Little Stars. With Zero appearing to investigate the disappearance of Ultra Capsules, Kei staged an attack via Galactron, holding both his fans and Geed as hostages while forcing Zero to sacrifice his own life. Although Zero revived afterwards with a new form, Kei started to take interest in the turn of events.

"Ultraman Geed! Being forced to strike someone who looks so much like master Belial is nauseating! You don't deserve master Belial's favor! I do! I am better than you!"

―Kei Fukuide, episode 11

Kei watches his master's arrival to Earth

After his presence caught the attention of AIB (who in turn discovered Belial's location), Kei hastily tried to take Riku's Capsules by force, first using the hired assassin Alien Bado and later on transforming into Pedanium Zetton. Due to his failure in securing all collection (accidentally leaving behind a Capsule (Zero) to the boy) Kei plunged the remaining sets into his conversion organ and transform into Pedanium Zetton again as a comeuppance. Fighting against Geed Magnificent, the combination of the Capsules' powers and his jealousy for Riku turns him into a mindless maniac who repeatedly throws tantrum towards his own creation before being subjected to defeat. Although he loses the Capsules, Belial was more than satisfied with the result while allowing him to rest.

"That's right! That's who I lost... master Belial! He gave me purpose when I was nothing but an empty vessel, a hollow existence! And now he's gone... He's gone!"

―Kei as he regains his memories from Dada's Legionoid.

Kei recuperating from his injuries.

Still injured from his past battle, Kei returned to Earth and witnessed Belial's defeat. After this, Kei suffered amnesia as a result of his injuries, and found himself on the run (for killing his editor) from the authorities, AIB and the Ultras alike. An assassination attempt from a Dada restored his memory as he contemplated to inherit Belial's mantle while finding refuge under the non-fiction writer Arie Ishikari. Inheritor of the Dream During a temporary takeover in the Nebula House, Kei recuperated from his injuries and attempted to exploit RE.M. before being kicked out. Nonetheless, he had unlocked the safety protection in RE.M.'s data-bank, allowing her access the repressed information that Belial left. Nebula House Invasion

"Master Belial...I will always be on your side."

―Kei's final words

Reclaiming the Kaiju Capsules of Dark Lugiel and Alien Empera from AIB after using Arie as bait before killing her, Kei went to Okinawa to permanently strengthen his Sturm Organ by absorbing his homeworld's light and calling forth Riku to settle their feuds. After his loss, Kei meet Belial, revealing himself to be possession of Arie and tearing out his Sturm Organ to revive himself once again. Kei then leaped into the sea while Zena and his agents pursued him.

Severely weakened by the loss of his Sturm Organ and left with a few days to live, Kei continued to pledge his loyalty to the dark Ultra. While Geed fought Belial in a climactic final battle, Kei attempted to ambush Leito Igaguri’s family, but he drew out his last breath during a swordfight with Laiha, who arrived to protect the humans. Before vanishing into green particles, Kei questioned whether he was just a pawn to Belial.


Kei Full.png
  • Height: Human-like
  • Weight: Human-like
  • Home World: Planet Sturm
  • Weaknesses:
    • As with all Alien Sturm, the Sturm Organ is Kei's vital part, acting as his life support. Without it, he only have a few days to live.
    • When Kei injects the Ultra Capsules into his body to transform, their excessive energies can cause mental instability, almost driving him to the point of insanity.

Like Riku, Kei is capable of performing Fusion Rise to transform into Belial Fusion Beasts by scanning two Kajiu Capsules with his Riser.

Main article: Skull Gomora

"Gomora! Red King! This is the end mark."

―Kei's pre-transformation announcement

"Fusion Rise: Gomora! Red King!"

―Activation announcement

"Ultraman Belial: Skull Gomora!"

―Transformation announcement

After scanning both capsules, Kei presses the trigger of the Riser and transforms into "Ultraman Belial". As the background changes into an eclipse, Kaiju Capsules of Gomora and Red King appear briefly before "Belial" inhales them, morphing into and creating Skull Gomora.

Main article: Thunder Killer

"Eleking! Ace Killer! This is the end mark."

―Kei's pre-transformation announcement

"Fusion Rise: Eleking! Ace Killer!"

"Eleking! Ace Killer! This marks the end for you!"

―Kei's pre-transformation announcement

"Fusion Rise: Thunder Killer!"

―Transformation announcement

Kei activates the Eleking and Ace Killer capsules, then loads them into the Riser as usual. However, Kei is not shown to transform into "Belial". Instead, Kei transforms in a burst of bright light after activating the Riser.

Main article: Pedanium Zetton

"King Joe! Zetton! This is the end mark."

―Kei's pre-transformation announcement

"Fusion Rise: King Joe! Zetton!"

After scanning both capsules, Kei presses the trigger of the Riser and transforms into "Ultraman Belial". As the background changes into an eclipse, Kaiju Capsules of King Joe and Zetton appear briefly before "Belial" inhales them, morphing into and creating Pedanium Zetton.

Kei first injects the Ultra Capsules (stole from Riku) into his body, as they glow blue. Kei emits large amounts of dark energy as his eyes start to glow red and red lightning emits around his body. His body transforms into a dark red energy sphere which swells up until Pedanium Zetton bursts from it.

"This is the end mark."

―Kei pre-transformation announcement

Kei scans the Kaiju Capsules of Zetton and King Joe, inserting them and scanning them together with the Riser. Kei then transforms into an evolved state of Pedanium Zetton with swirls of green and red energies appearing in the said Kaiju's back.

Main article: King Galactron

"King Joe! Galactron! This is the end mark."

―Kei's pre-transformation announcement

"Fusion Rise: King Joe! Galactron!"

―Activation announcement

"Ultraman Belial: King Galactron!"

―Transformation announcement

After scanning both capsules in real time, Kei presses the trigger of the Riser and transforms into "Ultraman Belial". As the background changes into an eclipse, Kaiju Capsules of King Joe and Galactron appear briefly before "Belial" inhales them, morphing into and creating King Galactron.

Powers and Weapons
  • Riser (ライザー Raizā): He has a Riser, same as Riku's. He obtained this by stealing it from the Land of Light.
    • Fusion Rise (フュージョンライズ Fyūjon Raizu): The standard ability of a Riser is to fuse the powers of two capsules into a single form/transformation. Kei uses it to transform into Belial Fusion Monsters.
    • Kaiju Summon: Apart from allowing him to Fusion Rise, Kei can use the Riser to manifest a Kaiju by scanning a Kaiju Capsule.
  • Kaiju Capsules: Kei has the Kaiju Capsules, as a purpose to summon Kaiju or combine them into Belial Fusion Monsters through his Riser. He can also create them by drawing a blank Ultra Capsule to absorb a defeated Kaiju's remains.
  • Ultra Capsules: Kei was temporarily in possession of Riku Ultra Capsules after stealing it from Riku when Riku failed to defeat Kei as Pedanium Zetton. His own use is to convert the Ultra Capsules power into malicious energy and transforms into Pedanium Zetton.
  • Cane: Not so much of a weapon, Kei's cane in his formal wear was shown capable of fending himself against Laiha's sword and knocking down an Alien Neril.
  • Dark Energy: Bestowed from Ultraman Belial, Kei possesses dark energies which serves as the main key of Fusion Rise into Belial Fusion Monsters. It appears that he needs to replenish his dark energy periodically. Whenever he uses them, a gleeful laughter of Belial can be heard from the background. After shoving the Ultra Capsules to his inversion organ, Kei's body begins to house its own dark energy.
    • Energy Shockwave: Kei can send a purple shockwave from his hands, this is strong enough to kill a Dada.
    • Energy Blast: Kei can fire a blast of red energy from his hands.
    • Energy Punch: Kei charges his fist with dark energy and punches the opponent. He does this to Riku, although he appears unscratched, partially due to his inhuman traits.
    • Energy Blade: Kei can release an energy blade from his hands that is able to pierce through a human body. Kei used this to kill Arie Ishikari.
    • Little Star Detection: Through Kei's own eyes, he is capable of detecting Little Star energy auras even from a distance. He retains this power when transformed into any Belial Fusion Monsters.
  • Natural Abilities: Abilities which are naturally his and not the result of the dark energy bestowed from Belial.
    • Carellen Element (カレラン分子 Kareran Bunshi): From his own chest, Kei release particles that would circulate the universe and attract Childhood Radiation energy matter, which would be absorbed into living beings to mature as Little Stars.
    • Intelligence: Kei was able to create Riku using a sample of Belial's genetic code, implying he has great scientific ability in the field of biology. He also seems to be an expert schemer hatching plans that only seem to fail due to unexpected variables.
    • Mental Abilities: Kei possess a variety of mind powers, including:
      • Astral Projection: Kei is capable of communicating with beings from a distant galaxy, doing so to meet his master Belial. When doing so, his appearance is projected through Talpa Waves (タルパ波 Tarupa-ha), linking to his original body from the Earth. His transmission signal is stated to be faster than lightspeed but is prone to being detected by certain forms of technology.
      • Psychic Burst: Kei can focus his telepathic power into a medium like a video recorder and cause a burst of energy where the information feed is being received, resulting in machines malfunctioning and exploding.
    • Sturm Organ (ストルム器官 Sutorumu Kikan): The natural organ of Alien Sturm outside their human-like appearance. Without it, he will be dead in days. However, Kei lost this organ as Belial is now in possession of it as he as Arie took out from Kei's body and absorb into his body. Its function includes:
      • Energy Transmutation: The Sturm Organ is capable of convert/manipulate/reverse the nature of energy, such as turning heat into cold. Kei used it per Belial's orders to corrupt the power of six Ultra Capsules, which forcefully transforms him into Pedanium Zetton.
      • Sturm Barrier (ストルム・バリア Sutorumu Baria): Kei can erect a force-field consisting of reddish pentagons. This trait allows Zero to identify Kei's true identity in general. According to RE.M., the nature of this barrier is that it erases power and negating attacks. Kei briefly lost access to this power before regaining it after his recuperation.
      • Absorption: By bathing himself in Planet Sturm's light, Kei can permanently strengthen his Sturm Organ.
    • Teleportation: Kei can teleport, seemingly by dissolving his body before reconstituting at a different location.
    • Deflection: Kei can block attacks by simply raising his palm and generating an invisible field of energy to deflect/block projectiles.

Ultra Capsules

As of episode 11, Kei stole all but one Ultra Capsule (Zero) from Riku Asakura after his defeat as Geed. By injecting them to his body, his conversion organ can corrupt its powers to transform him into Pedanium Zetton until its destruction cause them to scatter around the city before Riku and his friends recollect them.


As a famous sci-fi writer himself, Kei has multiple works in his novel. Among the identified titles are:

  • Cosmo Chronicle (コズモクロニクル Kosumo Kuronikuru) - Debut work
  • Galactic Battleship El-Shade (銀河戦艦アルシェード Ginga Senkan Arushēdo)
  • The Ambient Starry Sky (星空のアンビエント Hoshizora no Anbiento)
  • Spacetime Destruction (時空破壊 Jikū Hakai)
  • Dark DNA (暗黒遺伝子 Ankoku Idenshi)


  • Kei's name is a reference to sci-fi writer, Philip K. Dick.
  • Kei's actor (Kunito Watanabe) previously auditioned for the role of Jugglus Juggler of Ultraman Orb. Although Watanabe lost to Takaya Aoyagi, Kei instead performs a similar role to Juggler and is regarded by some fans as the second awakening of said character in terms of role and appearance.
    • According to his actor, Kei's Riser is a hint to his true nature. This was most likely referring to his being an extraterrestrial, despite (like Juggler) appearing human.
  • As shown in episode 7, his fans declared themselves to be Fukuidists (フクイデスト Fukuidesuto), which was seen by Japanese viewers as a minor reference to the real life famous writer Haruki Murakami and fans of his work.
  • Paralleling the elements of Ultraman Leo into Ultraman Geed, Kei's role is comparable to that of Black Directive, though instead of commanding an army of a monster class, Kei transforms into them.
  • Several of the titles of his novels parallel to the events concerning himself and Belial:
  • Carellen Element, the material which Kei created and used to attract Little Star is a tribute to Karellen, an Overlord and the "Supervisor for Earth", the character from Arthur C. Clarke's novel, Childhood's End. The fact that Kei's race (Alien Sturm) is named after Rikki Stormgren, the only man who ever spoke with the Overlords is rather interesting.
  • During planning stages of the series, Kei's 'occupation' was going to be either a doctor or a teacher.
