Ultraman Ace
Yapool, an ancient creature from another dimension with similarities to Satan and Legion, was an extremely skilled being of many conciousnesses with a knack for creating biological creations known as Choju. Yapool set his sights for Earth, but the original Five Ultra Brothers sent with their youngest member, Ultraman Ace and Earth's attack team at that time, TAC would came to stop him. Yapool would send many monsters to defeat Ultraman Ace, even seeking alien allies but all failed.

Vakishim
For once, Yapool decided to take the matters on his own by turning himself into Vakishim (バキシム) to attack Earth, first by attacking Minami (the female co-host of Ultraman Ace.) While she managed to survive, Vakishim managed to possess (or possibly impersonate) a small boy and used him as a puppet to hide from TAC. As the boy, he set his parents' and his home village on fire in a brutal display. Once TAC found out about the truth, Vakishim escaped from the boy's body and transformed into his true form and fled through his dimensional portal. Vakishim reappeared out from a different portal near TAC's HQ and proceeded to attack, with nothing that TAC's fighter jets could do. Finally, Ultraman Ace arrived to do battle and after a long brutal fight, Ultraman Ace destroyed Vakishim's horn with the Star Beam Cutter and kills Vakishim with the Palm Cutter followed by the Ace Slash. Despite Vakishim's defeat, but Yapool managed to survive in his own.

Strange Old Man and Giant Yapool
In episode 23, Yapool took action on his own again, plotting a global scale plan with his two new alias, The Strange Old Man (怪老人) and Giant Yapool (巨大ヤプール).

One day, Yapool for the first time schemed an invasion on their own hands without using Chojus. They started off by sending an agent of them in disguise as an old man, kidnapping children from around the globe by singing a hypnotic music and sent them into their dimension. While Hokuto was patrolling, he saw them but it took Yapool's teleporting ability to catch his attention and rushed to the beach where his kidnapping plot took place. Once arrived, the Strange Old Man transformed his head into that of a gorilla and summoned a snowstorm before he attacked Hokuto with his Fire Breath and made him fell from a cliff. Fortunately, he survived but heavily injured.

Knowing how far Yapool had gone through TAC decided to attack Yapool in his own domain. Using a special dimensional traveling device TAC sent Hokuto first because he volunteered. However, as the traveling started Yapool began to disrupt it and nearly teleported him into another dimension, but Zoffy arrived and managed to allow him and Minami to become Ultraman Ace. Once Ace was in his dimension Yapool combined themselves and used their anger over Ace and TAC to turn into a single entity, Giant Yapool. The battle between the two giants commenced as Giant Yapool and Ace exchanged beams until he was incapable of going on much further. With Giant Yapool beaten, Ace decided to leave his dimension. The Strange Old Man fainted after his comrades' defeat affect him as well and returning the kidnapped children once and for all. Although Yapol was not killed he would be incapacitated long enough for other aliens to attack Earth while he recovered.

Woman Yapool
Yapool later schemed his vengeance on Hokuto, who was now the sole host of Ace since Minami had left after countless failure of his plans. He disguised himself as a female dentist and tried to make Hokuto to cause him to go insane by placing a hallucination chip on his teeth while he was given a dental care, causing Verokron II to appear only in front of his eyes everywhere. After Hokuto saw several delusions of Verokron II not seen by anyone else and had taken action himself, he was fired from TAC for his unwarranted assault on what they did not see.

Without Hokuto in TAC anymore Yapool felt satisfied and unleash the real Verokron II to attacked a city. Woman Yapool's tricks later foiled and killed by Hokuto himself when he fired his gun at the fiend, as he fainted and reduced to bubbles. The real Verokron II was eliminated by Ace afterwards while his dental clinic mysteriously disappeared the next day.

Alien Simon
Although seemingly dead, Yapool had survived, and then used this alien form (in a juvenile state) as a disguise. He first pretended to be targeted by Yapool in order to get closer to TAC. He later escorted some kids away to safety when Jumbo King attacked the city. Despite talking only in his kind's language but later he told Hokuto via specialized telepathy that he is Yapool in disguise and his true plan was to getting his revenge on TAC, Hokuto/Ace and depriving the children's kindness. Once again, Yapool was killed (seemingly for the last time) by Hokuto before transforming into Ace and fighting Jumbo King. Jumbo King was defeated & Yapool's reign on Earth finally ended. Or Did it?

Ultraman Taro
Many months after Ultraman Ace defeated his most powerful choju, Jumbo King, Yapool hid himself into exile and somehow created a vehicle that not only allowed him to enter Earth's dimension, but in space. To defeat Ultraman Taro He made Oil Drinker but killed by Astromons then he revived Bemstar. But Unlike the original, Yapool would make his own modifications to the native being of the Cancer constellation and turn him into Reconstructed Bemstar. ZAT was well aware and alert of the situation and tested a new type of giant buzz-saw on Reconstructed Bemstar they claimed was exactly like Jack's Ultra Bracelet, but Yapool's modifications proved that it was not enough to defeat Reconstructed Bemstar. After Reconstructed Bemstar defeated Taro, Yapool demanded him to eat the rest of the oil refinery he was attacking. ZAT returned & began to attack Bemstar. After Bemstar was starting to lose his spirit after being repetitively stabbed in the eyes by a man Yapool revived Sabotendar to kill the man. Soon Kotaro returned, transformed into Taro & began to fight Bemstar & Sabotender. Furious that Taro was still alive, Yapool revived Verokron II to take care of the situation only for all the Monsters to be defeated. Yapool tried to retreat from Earth's atmosphere, but Taro made his vehicle explode with him inside using his Storium Ray, defeating him for good.

Ultraman Mebius & The Ultra Brothers
In the 1980s, the ever plotting Yapool sent a new choju of his, called the U-Killersaurus, to dispose of Ultraman, Ultraseven, Jack, and Ace. The battle began on the moon, with the four Ultras dodging everything U-Killersaurus threw at them. Grappling with the beast proved futile, as its strength was enough to hold off two Ultras at once. Yapool laughed at their efforts. He claimed that U-Killersaurus was created from the hate of the Yapool. When the four Bros. tried to use their beams on the choju, it flew towards Earth. The heroes tried to stop U-Killersaurus, only to be met by a barrage of his organic missiles. Avoiding those, the Bros. prepared to launch their beams again, when Ultraman halted them; firing their beams so close to the Earth could harm the citizens. After grappling with U-Killersaurus' extendable claws, it was then that the four of them did the only thing they could do without harming Earth: imprison U-Killersaurus in a dimensional prison with its creator, Yapool. After crippling U-Killersaurus by blasting off his limbs, Jack and Ace combined their Specium and Metallium Rays to send U-Killersaurus plummeting into the Earth. The Bros. arrived at the scene, and, using the Final Cross Shield, the four Bros. sealed U-Killersaurus and Yapool into the bay they had landed in.

"Commrade? Don't make me laugh. He was nothing but sacrificial pawn."

- Yapool as he reveal his betrayal against Alien Nackle.

For twenty years both Yapool and U-Killersaurus would remain sealed, until he duped a group of aliens, Temperor, Zarab, Guts, and Nackle into free them. After finally being revived by Alien Nackle and Alien Guts, U-Killersaurus was even more powerful than before. Yapool was revived as well, and casually killed his supposed ally, Nackle (Guts was destroyed by Mebius). As far as he was concerned, Nackle was just a pawn. U-Killersaurus then proceeded to mercilessly beat the Ultra Bros. with his new strength. Even when Ultraman Taro and Zoffy arrived to assist the brothers, they still could not stop this juggernaut of a monster. U-Killersaurus Neo soon caught Mebius with his large pinchers, and prepared his ultmite attack in order to kill him. However, the remaining Ultra Bros. combined their power with Mebius, and the result was Ultraman Mebius Infinity. U-Killersaurus Neo was helpless against him, as he easily smashed into his body and came out the other side, causing U-Killersaurus Neo to decay into dust, along with Yapool, ending his terror until Alien Empera revived him months later.

Ultraman Mebius
Yapool then reappeared in Ultraman Mebius episode 24 and became a recurring antagonist in the show.

On a normally quite day, the sky began to rain blood-red rain. It covered everything in sight. That night, GUYS members Mirai and Ryu were sent out to investigate. Suddenly, out of nowhere, the sky seemed to crack open like glass, a large figure loomed over them! It unleashed two beams of energy at them from its nose, but both managed to dodge. Ryu tried to shoot his weapon, but the creatures eye glowed bright blue, and an energy wave came from it, and imprisoned Ryu in an orb of some kind.

Mirai tried to turn into his Ultra form, but the creature let loose with another nose blast. He dodged the blast, but the resulting explosion knocked him down and injured his left arm. The creature then seemed to absorb Ryu into his eye, and then disappeared, as the night sky seemed to come back together again. Mirai blacked out, and woke up in the GUYS HQ, with Ryu standing there as if nothing had happened. However, Ryu was being controlled by Yapool, who was behind the appearance of the monster. Some time later, during the testing of the new Fire Windam, the controlled Ryu used an odd device that set off the GUYS aircraft to attack Windam. Windam tried to strike back, but he returned to his capsule. Ryu then shot Mirai in the arm, injuring it further. But his true identity was soon exposed by Captain Shingo Sakomizu. Yapool then summoned the same monster to attack.

The beast broke the sky like glass yet again, and jumped out to land, and begin its attack with Konomi identified the monster as Vakishim. While Ryu walked away and Mirai gave chase, the other members tried to attack Vakishim with their weapons, but it was useless. Yapool threatened Mirai with the odd device, but Mirai had to choice but to shoot Ryu, thus causing Yapool to leave, and return to Vakishim's eye. Angered by his friend being used like that, he assumed his Ultraman Mebius form, but his left arm was still hurt, and Vakishim easily beat Mebius to the ground. GUYS, however, stepped in and fired their weapons at close range, in order to give Mebius enough time to switch to Brave Mode. And, with one mighty slash, Vakishim was destroyed by his blade. Unfortunately, Yapool was still alive.

Days later, appearing out of the sky and without warning, the next of the Choju made its appearance from the same mysterious dimension that Vakishim came from: its name was Doragory. He instantly began attacking the surrounding area with a blast of his red energy bolts. GUYS quickly flew into action, attacking the monster with their aircraft's weapons. Doragory eventually gave up, and returned to his odd dimension before GUYS could land any more blows. Later, while George stayed in a hotel room with his "girlfriend," he heard her scream, and rushed over to see a large dragonfly on her, which was actually Doragory.

George tried to swat it away, but it turned into a purple gas, and entered her body. When she awoke, she hit George with a blast of energy from her eyes, which knocked him out. Later, he met her again, and discovered she was under the control of Yapool. After a failed attempt to destroy a new weapon of GUYS, Doragory and Yapool left her body, and manifested itself into its normal form outside, with Yapool intact. In no time flat, GUYS was all over the monster, attacking it with their handguns. Doragory shot an eye bolt at Mirai, who was caught in the explosion, but was still able to turn into Ultraman Mebius. The two titans fought hard, with Mebius seeming to have the upper hand, until Doragory managed to knock down Mebius, and jump on top of him, grabbing his face with his hand. GUYS knew they had to act fast, since Doragory was known for tearing the flesh off others with ease. George blasted Doragory in the face, which gave him the chance he needed to use his new beam weapon: the Mebium Infinity Beam, which blew Doragory clean off his feet! The Choju then tried to escape using his dimension breaking powers. While Mebius switched to Brave Mode, George tried out the new weapon: The Meteor Overdrive, which evaporated the shattered dimension, closing Doragory' window of opportunity. Mebius then used another new beam weapon: the Infinity Cross-Beam, which destroyed Doragory completely. But Yapool had one more trick up his sleeve.

Then one day, Verokron appeared suddenly in his hole while Captain Shingo was out and about. He tried to prevent its appearance by shooting the hole with a new gun that could close the holes made by Choju. It worked, but not before Verokron fired a missile at him. He was caught in the explosion, and fell unconscious while Verokron disappeared. Much, much later, Verokron reappeared in an open area near GUYS HQ, while they were still developing a new weapon, as well as converting their HQ into a flying airbase. GUYS attacked Velokron with their aircraft, but their missiles and gun blasts were all nullified by Velokron's endless barrage of missiles. Suddenly, the sky began to crack like glass, with a purple glow to it: The Yapool were trying to break through! GUYS flew in to get rid of it, but Velokron fired missiles at them. Luckily, Ultraman Mebius appeared, and stopped the attack. The Choju put up a good fight, but was easily beaten in the end, as GUYS used its new weapon to close the nearly open dimension hole for good, preventing any more Choju from appearing, as well as the Yapool. Mebius then used his Mebium Beam, and destroyed Verokron ending the attack of the final Choju for good.

Red King & Gomora
The gas monster Gadiba was first released by a mysterious man dressed in black, who was really Yapool. Yapool had Gadiba dig itself into an open field of rocks, and bring Red King back to life! Gadiba then entered its body and gave it new abilities. After Red King was revived by Gadiba, he began kicking and thrashing the rocky area all around him. GUYS quickly detected it, and set out. As they arrived, Red King began tossing rocks at them, as it had no other means of attacking airborne foes. Their weapons proved useful, and Red King was soon out of rocks. But it quickly smashed a mountain and created more, which it continued to toss at the GUYS aircraft.

As Red King raised a large boulder, GUYS managed to shot his hand, causing him to drop it out his foot. Red King screamed in pain, and kicked the offending boulder in frustration, but this only hurt his foot more. GUYS closed in, but Red King was not beat yet; using its thick tail and powerful legs, Red King launched himself into the air, straight at the GUYS main aircraft. Lucky for GUYS, Mirai was on board that aircraft, and turned into Ultraman Mebius. He swiftly kicked Red King, still in mid-air, and the lumbering behemoth fell to the ground below. Red King got right back up, however, and the two titans battled. Although stronger than the original Red King, Mebius had little trouble dealing with this revived Red King, as he easily knocked it into a mountainside, where its head became stuck. Red King eventually managed to free itself, but was too dizzy to continue fighting, and Mebius finished it off with his Mebium Beam. But the body was not destroyed, and suddenly, the gas monster Gadiba left Red King's body, and created a series of rings around it. Upon re-entering, Red King morphed into Gomora. Gomora got to its feet and stood tall, roaring loudly. Mebius, weak from his fight with Red King, now had to face a refreshed Gomora. He was easily knocked around and slammed to the ground; GUYS stepped in, and used nearly every weapon in their arsenal! Gomora's tail was blown off, but this only proved to be a problem, as it began attacking Mebius on its own! The GUYS aircraft fired a barrage of energy beams at the tail, destroying it, but Gomora still had plenty of fight left in him. Mebius' color timer began blinking, but he didn't give up; he stoop up, and transformed into his Burning Brave Mode! With one punch to the gut, and a single kick to the face, Gomora was already beaten, but Mebius grabbed and tossed him high into the air. Then, he used his Mebium Bust in combination with one of the GUYS energy weapons, destroying the ancient beast completely. Gadiba, however, was not destroyed.

The Four Heavenly Kings
After GUYS and Mebius left, it later returned to its master, Yapool, who then returned to his own demented dimension, laughing manically. Upon returning to his dimension, he met up with three other beings; Deathrem, Grozam, and Alien Mefilas. These four beings were survivors of the Great Ultra War, who had come together to comtemplate the destruction of the Ultra Brothers. Yapool announced he was to be the first, and only, one to confront Ultraman Mebius, as he would destroy him easily, but Desrem wanted to kill Mebius himself. Yapool teleported away, and just as Deathrem was about to give chase, Mefilas stopped him, saying they should wait and see what Yapool will do first. Mirai had gone on a walk in the park with Aya he'd met, but Yapool was spying on them, disguised as a human once more. He held a clutch of ballons with him; these looked innocent, but had devious powers. Yapool finally confronted Mirai, as he was dealing with an annoying, smug reporter, revealing his true identity as Yapool. But rather than fight him, he released a red ballon with gold stripes into the sky. The ballon opened up a dimensional hole, and from it, Ace Killer emerged! Yapool teleported to a safe distance to observe, as Ace Killer made his way toward Mirai, crushing anything in his path. The reporter made a hasty getaway, but Mirai stayed with Aya, telling her to run, and that he'd take care of Ace Killer. Mirai ran off to transform into Ultraman Mebius, but unknown to him, she followed him, and witnessed his transformation. Mebius confronted Ace Killer, who proved to be a much better fighter. Things only got worse as Yapool called Gadiba into action. The little gas monster leaped into Ace Killer's body, and gave him new abilities; he was now Mebius Killer! Yapool ordered Mebius killer to first use the Mebium Beam; placing his left palm over the green pendant on his right forearm, Mebius Killer charged his hands with energy, and performed the Mebium Beam. It struck Mebius' body, but he sidestepped most of it. Yapool, laughing, ordered him to fire it again, but this time, Mebius fired his own Mebium Beam, and the two were evenly matched. Yapool then ordered Mebius Killer to use the Mebium Blade, which formed out of his green pendant. Mebius pulled out his blade as well, but Mebius Killer was stronger still, and outmatched him. Finally, Yapool ordered him to use the Mebium Bust. The ball of fire struck Mebius with great force, and Mebius fell to the ground as Yapool laughed. Mebius tried to get up, but he was too weak. That's when the Aya ran up and spoke to Mebius; she believed in him and his strength. Mebius wouldn't give up now, and he got back up to fight once more. This time, however, Mebius was winning. Mebius Killer grappled with Mebius, and was overpowering him. That's when Mebius pulled out his newest power; his body began glowing red, and then he engulfed Mebius Killer and himself in flames! It was Mebius' version of the Ultra Dynamite move Ultraman Taro uses; the Mebium Dynamite! Mebius Killer groaned in agony as Mebius' flames burned his flesh, but Mebius kept a good grip on him, and finally, with one last burst of power, Mebius caused the finishing explosion, destroying Mebius Killer once and for all.

Mebius later returned to human form, and the Aya ran up to see if he was OK. The smug reporter reappeared, saying he knew Mirai was hiding something, referring to his Ultraman form. Just then the ground opened up and all three fell into the deep, dark abyss; Yapool's trap. When they awoke, they were in a twisted, futuristic world, in which Tokyo was in ruins. As they entered the city, Yapool appeared before them, and began toying with the reporter, using his psychic powers to shove and choke him. Then, he released him and told him he'd allow him to go free, back to his world, if he shot and killed Mirai he presented him with a large laser gun, and the reporter took aim and fired at Mirai. However, Mirai created his energy shield and protected Aya and himself until the reporter ran out of ammo, and Yapool shoved him aside. The reporter was freaked out at what Mirai was doing and how he had such powers, and was too afraid to approach him. Mirai then challenged Yapool to fight, of which he gladly accepted. Yapool assumed his giant form, and Mirai assumed his Ultraman Mebius form. Yapool told Mebius that as they spoke, at this very moment, GUYS were stranded on the moon, and were about to be slain by the moon Choju Lunaticks, and he laughed with much evil in his voice. Mebius and Yapool fought, but it was clear who had the advantage, as Yapool used his psychic hold to swing and toss Mebius every which way, as well as slashing him with his blade hand. Mebius was still weak from his encounter with Mebius Killer, and could barely fight back. Yapool continued to taunt and cackle at Mebius for being so weak, and he began firing energy blasts from his balde, which tore into Mebius' flesh.

But like before, Aya walked toward Mebius, and continued to speak of how he was an Ultraman, and how he could overcome this obstacle. Yapool, sick of hearing her voice, blasted the area in front of her, nearly killing her. Mebius tried moving, but was too weak, and he collapsed, with his eyes growing dark. It was then that Seiji Hokuto, Ultraman Ace's human host, spoke to human through his mind. He said that if he has someone that is precious to him, he can and will overcome any foe. Mebius' power and spirit were restored, and much to Yapool's surprise, he stood up once more, and assumed his Burning Brave Mode. This time, the tide of the battle turned, as Mebius went on an all-out attack on Yapool with intensity never before seen in an Ultraman. After Mebius slammed him to the ground, he used his Mebium Bust, and with all his might, tossed it at Yapool. However, Yapool was not destroyed yet, but he was indeed dying. His last words were that of informing Mebius that more foes, even stronger, would come, such as Desrem, and Grozam. then, he fell to ground, and his body exploded into dust. Yapool was finally finished. Grozam, back with Mefilas, exclaimed that Yapool was killed. Mefilas, however, did not care, and proceeded to tell Grozam that Deathrem had already left for Earth by himself.

Ultraman Mebius Gaiden: Ghost Reverse
Yapool was revived and possessing his creation, Mebius Killer. Yapool, along with Deathrem, Glozam, and Armored Mefilas assault the Ultra Brothers in an attempt to reunite the Giga Battle Nizer and Zamsher (now known as Mecha-Zam,) in an attempt to resurrect Alien Emperor. However, their plans are foiled when Ultraman Mebius looses the Giga Battle Nizer and Mecha-Zam sacrifices his life to keep the Emperor from being revived. After a battle with Ultraman Ace, he was finally destroyed by a single shot of his Metallium Ray.

Ultraman Ginga
Yapool appeared in Ultraman Ginga as a Spark Doll. In episode 7, he along with many monsters are seen cheering on Ultraman Ginga as he fights Dark Galberos. It is likely that Yapool departed back to his dimension after the defeat of Dark Lugiel.

Ultraman Ginga S
Yapool return with Vakishim on Ultraman Ginga S episode 5, this time inside his Giant Yapool body for most of his appearance.

Yapool appears when Vakishim was fighting Ginga. Angry at Android One Zero for using Vakishim's Spark Doll without permission, he took control of the Choju away from the android and cast her out of the Lived Doll. He then sent the choju back to his home dimension and told One Zero and Exceller that he will deal with Ginga, knowing about the Chibu's plan to steal the Victorium, and then he vanished, planning on something diabolical with the humans. This event revealed that Yapool was in Vakishim when the monster had turned into a Spark Doll, thus resulting him slumbering inside the choju.

Soon he possessed Gouki Matsumoto and went on a small rampage and even trapped Hikaru Raido in a Dimensional Rift. When Gouki struggled with Yapool for control after seeing a pregant woman needing help and taking her to a nearby hospital, the choju maker transformed into his giant form with Gouki still possessed and was about to strike Arisa Sugita and her UPG vehicle but Gouki fought back until Ginga kicked Yapool, freeing Gouki from his possession. He then ordered Vakishim to retreat back into their dimension but Ultraman Victory followed suit and brought it back. He then fought with Ginga himself who transformed into Strium form and Victory "UITrans" his right hand into the Gudon Whip. After Vakishim's defeat, he tried to return to his dimension, but Victory stopped him and he was then defeated by Ginga using the Metallium Ray.

Ultra Fight Victory
"Evil dimensional people never die, and the bitter animosity towards the Ultra Warriors allowed me to return with deeper darkness than ever."

- Yapool explaining to Sakuya how he survived his last fight with Ginga and Victory.

Yapool returned in Ultra Fight Victory as the one responsible for sending the Choju. He somehow survived his destruction during his previous defeat at the hands of Ultraman Ginga.

He was first seen studying Ultraman Victory's UITrans ability, while he was fighting Aribunta. Yapool appeared to Sakuya and confiscated her Victorium Necklace, while stating his plan to go to the Victorium Core. Afterwards, he went down to the Victorium core and used Sakuya's necklace to gather energy from the core itself. Yapool then revealed himself after Victory defeated Aribunta and stated he already had enough power to revive Juda. He then sent Doragory, Verokron, and Vakishim to fight Leo and Astra and protect the distortion that housed the reviving Space Emperor and ordered Ace Killer to stop Ace from saving Ultraman Ginga.

When Victory arrived, Yapool explained that he was able to copy the Ultra's UITrans, and had given it to Ace Killer, declaring him, Victory Killer and later summoned Lunaticks to kill Ginga. After both choju have been killed by Victory and Shepardon, and Ginga and Ace have been restored, Yapool went to Planet Gua and used the Victorium he stole from the core to kickstart the revival of Juda. He reveled in his glory until Ginga, Victory, and Ace showed up and fired the Victorium Shoot, Ginga Cross Shot, and Punch Laser respectively at the choju. Yapool then grew in size and joined the choju in fighting the Ultras and was winning over the new Ultras thanks to his bitter animosity towards the Ultra brothers empowering him until the old Ultras suggested that they merge to form Ultraman Ginga Victory and they did. The fight quickly swung into Ginga Victory's favor, and Yapool was defeated with the Ultra Fushion Shoot. However, Yapool stated that one can stop Juda's revival and that the universe will end and, as he exploded, he gave off enough minus energy to fully revive the emperor.

Ultraman X
Continuing from Ultra Fight Victory, it was revealed that Yapool not only revived Juda, but also Mold and Gina as well without notice.
