Kei Fukuide

Kei Fukuide (伏井出 ケイ) is a villain and the main antagonist 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 polite and gentle behavior.

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.

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 the 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.

After his presence caught the attention of AIB (who in turn discovered Belial's location), Kei hastily try 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... Belial-sama! 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.

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. 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.

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

Powers and Weapons

 * Riser (ライザー): He has a Riser, same as Riku's. He obtained this by stealing it from the Land of Light.
 * Kaiju Summon : Apart from allowing him to Fusion Rise, Kei can use the Riser to manifest a Kaiju by scanning it's respective Kaiju Capsules.
 * 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.
 * 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): From his own chest, Kei releases particles that would circulate the universe and attracted 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), 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): The natural organ of Alien Sturm outside their human-like appearance. 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.
 * Force-field Generation : 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.
 * Teleportation : Kei can teleport, seemingly by dissolving their 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.

Novels
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) - Debut work
 * Chapter 1:
 * Chapter 2: Title unknown
 * Chapter 3:
 * Galactic Battleship El-Shade (銀河戦艦エルシェード)

Trivia

 * Aside from being a servant, it is unknown if he would turn out to be a host of Ultraman Belial. The silver ring he wears, his image of Belial during mid-transformation of Belial Fusion Monsters and his line in episode 3 (meeting someone he dislikes) becomes a major mislead to fans if the two are the same person or rather, unwilling possession:
 * His red eyes (as a result of dark energies injected from Belial) are shared features from Darkness Five, a group that Belial had founded in Ultra Zero Fight.
 * His transformation into Belial Fusion Monsters is based on Kaiser Belial's transformation into Arch Belial. As shown, both "inhale" the parts needed to form a monstrous appearance.
 * His brief state of amnesia, along with how he regains his memories (remembering Belial's image) is based on Darklops Zero's reactivation after serving under the Alien Salome's faction on Planet Chain.
 * 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 Kunito Watanabe, Kei's Riser is a hint to his true nature. Despite the revelation of his race as Alien Sturm, this may be how he is not a human.
 * As shown in episode 7, his fans declared themselves as Fukuidist (フクイデスト), which was seen by Japanese viewers as a minor reference to the real life famous writer 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:
 * Space-Time Destruction: Refers to the Super-dimensional Eradication Bomb and the Crisis Impact. It also serves as a foreshadowing to Zegan's appearance.
 * Dark DNA: Refers to Riku Asakura's inheritance of Belial's genes.
 * 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.
