We were born from darkness, and taint everything with it. Ultra Brothers, this time I will surely destroy your light!
~ Yapool to the Ultra Brothers.
Curses - remember this! Though Yapool may die, Terrible-Monsters live on! They will surely avenge me!
~ Yapool after his first defeat.

Yapool is an immortal entity from another dimension and one of the main antagonists of the Ultra Series, first appearing as the main antagonist of Ultraman Ace. He bears many similarities to Satan and Legion. He is the archenemy of Ultraman Ace, and the first overarching antagonist in the Ultra Series, as previous 'final opponents' in the franchise were individual alien races that appeared in single finale episodes.

Yapool first reappears in 1973's Ultraman Taro as the main antagonist of a two-parter storyline, then returns as a major antagonist in 2006's Ultraman Mebius, serving as one of the Dark Four Heavenly Kings under Alien Empera. He also appears as a major antagonist in Ultraman Mebius Gaiden: Ghost Reverse, the main antagonist of Ultraman Mebius & the Ultra Brothers and Ultra Fight Victory, an overarching antagonist in Ultraman Z and a major antagonist in Ultraman Decker.

As the first main antagonist in the Ultra Series, Yapool has gone on to become one of the franchise's most iconic and enduring villains, having appeared throughout the timelines of numerous continuities since his debut in Ace.

He is voiced by Tatsuhiko Takada in Ultraman Ace and Ultraman Taro, and by Tessho Genda from Ultraman Mebius onward.

Biography[]

Ultraman Ace[]

Yapool original

Yapool during Ultraman Ace

Yapool began seeking to conquer Earth with his army of Choju. Noticing Yapool's ambitions, the Five Ultra Brothers sent Ultraman Ace to Earth. Ace teamed up with Earth's defense team at the time TAC, and began working with them to thwart Yapool's plans

After the failure of his Choju, Yapool attempted to take matters into their own hands. They sent an agent of theirs in the guise of an old man to kidnap children and send them to their dimension.

After noticing Yapool's plan, TAC decided to attack Yapool in their own dimension. They tried send Hokuto to Yapool's domain with a dimensional travelling device, but Yapool attempted to disrupt the device and send Hokuto to a different dimension. However, Zoffy showed up and allowed Minami to transform into Ultraman Ace with him. The Yapool then merged into a single entity, Giant Yapool.

Ace and Giant Yapool battled until Yapool was left unable to continue fighting. Ace then returned to Earth and freed to captured children. While Yapool recovered from the injuries he sustained, other aliens would attack Earth.

In order to get revenge on Hokuto (who had become the sole host of Ultraman Ace due to Minami's departure) Yapool took up the guise of a female dentist and implanted a hallucinogenic chip in Hokuto's teeth, causing him to see Verokron II everywhere.

After Hokuto's hallucinations led to him getting fired from TAC, Yapool unleashed the real Verokron II on a city. Yapool was defeated when Hokuto fired a gun at him that reduced him to bubbles, while Verokron II was destroyed by Ace soon after.

However, Yapool was not done just yet. The evil entity disguised himself as an Alien Simon as part of a plan to gain TAC's trust. Yapool had his strongest Choju, Jumbo King, attack a city so he could escort some kids away.

Yapool eventually revealed to Hokuto via telepathy his true identity and intentions to get revenge on TAC. Yapool was killed again by Hokuto, before he transformed into Ace and defeated Jumbo King.

Ultraman Taro[]

Yapool remodeled I

Reconstructed Yapool

After several months of laying low, Yapool made another attempt to attack the Earth. He revived Bemstar as Reconstructed Bemstar with modifications to make him stronger. Both ZAT and Taro proved unable to destroy the monster. When a man began stabbing Bemstar in its eyes repeatedly, Yapool revived Sabotender to kill the man. Eventually, Kotaro returned and transformed into Ultraman Taro to fight both monsters. Yapool revived Verokron II to defeat him, but all three of Yapool's monsters were defeated. Yapool then attempted to retreat but his ship was destroyed by Taro via the Storium Ray.

Mebius & the Ultra Brothers[]

Commrade? Don't make me laugh. He was nothing but sacrificial pawn.
~ Yapool after killing Alien Nackle
UBrothersVS UKill2

The Ultra Brothers fight with Yapool's U-Killersaurus

In 1986, Yapool yet again resurfaced back again with another plan to conquer Earth and destroy the Ultra Brothers. This time, he creates and summons the ultimate Choju, U-Killersaurus. The Ultra Brothers are alerted of the presence of this beast and together they face it on the moon and after a massive fight it seems like U-Killersaurus and Yapool have the advantage. With no other choice, the Ultra Brothers try to combine the beams in order to destroy U-Killersaurus. Howevere, it could cause great harm to civilians around, and thus the Ultra Brothers decided that the only choice was to seal Yapool and U-Killersaurus into the ocean, which succeeded and put an end to Yapool's plans for two decades.

Several years later, four aliens, Temperor, Guts, Nackle and Zarab plan to awaken U-Killersaurus for their own plans. When this succeeded, Yapool immediately killed off Nackle, commenting that he was just a pawn in his schemes. Together with the newly power U-Killersaurus NEO, Yapool proceeds to dominate Mebius and the rest of the Ultra Brothers, even with the newly arrived help of Taro and Zoffy. Before U-Killersaurus NEO could finish off Mebius however, the Ultra Brothers gave their energy to Mebius, transforming him into his Infinity form, which allowed him to easily fight and destroy the massive beast and kill Yapool in a massive explosion. This would be the end for Yapool until he was revived by Alien Empera some time later.

Ultraman Mebius[]

Mwa ha ha ha! You have lost! You're a powerless Ultraman who can't really do anything by yourself! Bwa ha ha ha ha ha!
~ Yapool taunting Mebius
Ultr Mbs Ypl

Yapool during Mebius' time

Yapool later returned in episode 24 as a member of the Dark Four Heavenly Kings and major antagonist on the show.

Yapool, using Vakishim, kidnaps and possesses Ryu Aihara, using him to trick the crew of GUYS into believing Mirai was really a disguised alien which needed to be killed off due to sabotaging GUYS' ships. Before he could shoot Mirai however, Sakomizu appeared and stopped him, noting that Ryu would never shoot Mirai. The Yapool possessed Ryu attemped to escape after summoning Vakishim until he was stopped by Mirai in his tracks, noting the host of Mebius that he had set bombs which would kill his friends. However, Ryu inside him fought with Yapool and ordered Mirai to shoot him. After some hesistance from Mirai, he was forced to shoot his friend, almost killing him, as Yapool gets out of his body, celebrating how Mebius just "killed" his friend, as he goes and takes over Vakishim's body. Mirai then transforms into Mebius and defeats Vakishim after a fight, but Yapool manages to escape.

He later met up with his fellow Heavenly Kings (Alien Mefilas, Grozam and Deathrem) to contemplate the destruction of the Ultras. Yapool announced to his fellow Kings that he would be first and only to confront Mebius. However, Deathrem wanted to be the one to fight Mebius and attempted to follow Yapool, but he was stopped by Mefilas, who told him they should wait to see what Yapool does first.

Yapool summoned Ace Killer to Earth to battle Mebius. Ace Killer easily had the upper hand in the fight, and things only got worse for Mebius when Yapool had Gadiba merge into Ace Killer to transform him into Mebius Killer. Mebius Killer brutally beat down Mebius. However, some encouragement from Aya gave Mebius the courage he needed to overpower and defeat Mebius Killer, destroying the robot with the Mebium Dynamite move.

Shortly after Mebius Killer's destruction, Yapool sucked Mirai, Aya and a smug reporter into a dark abyss containing a ruined Tokyo. Yapool then appeared before the three, and offered to let the reporter go free if he shot and killed Mirai with a large laser gun he presented to the reporter. The reporter attempted to shoot Mirai, but Mirai was able to protect himself and Aya. After firing at him many times, the report ran out of ammo and was cast aside by Yapool. Mirai then challenged Yapool to fight. Yapool assumed his giant form, while Mirai transformed into Ultraman Mebius. The two fought, with Yapool easily gaining the advantage, as Mebius was still recovering from his encounter with Mebius Killer, and could barely fight back.

Aya attempt to deliver some more words of encouragement to Mebius, but Yapool blasted her away. However, Seiji Hokuto, Ultraman Ace's human host, spoke to Mebius through his mind, telling him that if he has someone that is precious to him, he can and will overcome any foe. With that, Mebius' power and spirit were restored, allowing him to stand up and assume his Burning Brave Mode. Mebius then attacked Yapool and managed to defeat him with a Mebium Bust. Not dead yet, Yapool told Mebius that even stronger foes than him would come before collapsing to the ground and exploding into dust. Yapool was finally finished.

Grozam later informed Mefilas that Yapool was killed. Not caring, Mefilas informed Grozam that Deathrem had already set off for Earth.

Ultraman Mebius Gaiden: Ghost Reverse[]

Yapool as later revived along with the other three Heavenly Kings and possessed the body of his creation, Mebius Killer. The Four Heavenly Kings then attacked the Ultra Brothers to bring together the Giga Battle Nizer and Mechazam so they could revive Alien Empera. Their plans are ultimately foiled when Ultraman Mebius gets rid of the Giga Battle Nizer and Mechazam sacrifices himself to prevent the Empera from returning. Yapool was later destroyed by Ultraman Ace with a shot from his Metallium Ray.

Ultraman Ginga S[]

Angry at Android One Zero for using Vakishim's Spark Doll without permission, Yapool cast her out and took control of the Choju, sending it back to his home dimension. Yapool then told One Zero and Exceller that he would deal with Ginga before disappearing.

Yapool then possessed Gouki Matsumoto and began rampaging. However, Gouki began struggling with Yapool for control after seeing a pregnant woman needing help, prompting the Yapool to turn into his giant form. Ginga later kicked Yapool, freeing Gouki from his possession. He then had Vakishim to retreat back into their dimension but Ultraman Victory managed to bring it back. Yapool decided to battle Ginga himself but after Vakishim's defeat, Yapool attempted to return to his dimension. However, Victory stopped him, allowing Ginga to destroy him using the Metallium Ray.

Ultra Fight Victory[]

Yapool later returned with the intention of using the Victorium Core to revive Juda. He stole Sakuya's Victorium Necklace and used it to siphon energy from the Core itself. Yapool then revealed himself to Ultraman Victory and sent Doragory, Verokron and Vakishim to fight Leo and Astra. He also sent Ace Killer to keep Ace from saving Ginga, copying Ultraman Victory's UITrans and giving it to the robot, declaring him Victory Killer.

Yapool summoned Lunaticks to kill Ginga, but both it and Victory Killer were destroyed by Victory and Shepardon. Yapool then traveled to Planet Guar, where he used his Victorium to commence Juda's revival. Ace, Victory and Ginga soon arrived, prompting Yapool to engage them in battle. Yapool initially overpowered the Ultras, until they merged into Ultraman Ginga Victory. The fight then swung in the Ultras' favor, who defeated Yapool with an Ultra Fusion Shoot. Before dying, Yapool declared that none could stop Juda's revival. As he exploded, Yapool sent his energy to the Space Emperor, reviving him.

Ultraman X[]

Unbeknownst to the Ultras, Yapool had also revived Juda's older siblings, Gina and Mold, as well.

Ultraman Z[]

Though not physically present as he had yet to resurrect himself again, Yapool's hatred spawned a new Barabas who sensed Ultraman Ace's signature from one of Z's medals and attacked his Earth in response. It was vanquished by a team effort of Z and his godfather, Ace, who showed up to deal with the Choju. When beaten, Barabas roared in anger that Yapool and the Choju will never die.

Ultraman Decker[]

Yapool makes a physical reappearance in his Yapool Man form, unused since his original appearance. Yapool teams up with Agams and the Sphire to bring ruin to Decker's Earth and defeat Ultraman Decker; he first saves Agams from a TPU squadron before summoning one of his Choju, Aribunta, to create a diversion for GUTS-Select while he takes Kanata's and Agams' form to fool Ryumon Kirino as "Kanata", and Kanata as "Agams" to separate the trio and trap Kanata in his dimension. Kanata manages to escape and defeat Aribunta causing Yapool to retreat to the Moon in the next episode.

Following the defeat of Aribunta, Yapool retreats to the Moon where he takes control of some Zomborg Soldier robots to fight Kanata/Decker and Kengo Manaka/Ultraman Trigger, who defeat his squadron. Before he can do anything else, the Sphere turned on him and devoured his memories, leaving him incapacitated, before being blasted into oblivion once again by the Ultras.

Personality[]

Giant-Yapool-Top

Yapool, the interdimensional demon

Yapool, multiple times, has done awful things. They'll do anything in order to conquer Earth. That's who Yapool really is
~ The Narrator

Yapool can be easily considered amongst the franchise's most, if not, the evillest villain, even considering himself a "demon". Yapool is a being born out of darkness whose only desire is to conquer anything around him and the universe, and he'll do anything in order to reach that goal, and despite being killed he'll always come back thanks to his massive hatred of the Ultras. Yapool also manipulates people around him, tricking them with wishes his victims have, and can easilt turn them into mindless chojus of destruction to cause massive genocide, taking pleasure in the suffering of others. Yapool is also willing to destroy entire civilizations and kill millions for his plans, and has to be stopped by the Ultras. He is also uncaring for his own allies, as he kills Alien Nackle after he freed Yapool from his sealing, and threatened the other members of the Four Heavenly Kings to turn them into Chojus controlled by him. He also turns multiple innocent people and animals into chojus through painful transformations and make them lose any sense of their previous identity. Yapool is also a manipulator to the Ultras, even trying to convert Mebius into his side to help him, and also psychologically plays with the young Ultraman about how useless he is without his friends, while laughing at it. He can also mind control people (including children) to also taunt his victims and go forward with his plans.
