Yapool

is an evil entity and the main antagonist from Ultraman Ace. He has been defeated many times but proves to be immortal because of his eternal resentment for Ultras; while he can be felled in battle, it is impossible to truly kill him, as eventually his unceasing grudge will cause him to be revived. He also tends to avoid death due to his cunning and intelligence, and use of alternate forms and his creations, the Terrible-Monsters, to avoid detection. The first overarching antagonist of an entry in the Ultraman Series, Yapool has gone on to become one of the franchise's most enduring and iconic aliens, and has appeared throughout the series since his debut, often acting on his own volition or as part of villainous team-ups with other major antagonists.

==Conception==
===Etymology===
Yapool's name was taken from Shōzō Numa's 1956 cult science fiction novel, Kachikujin Yapu.
===Design===
Giant Yapool's motif is based on a crab and Great King Enma, the god who judge the dead and preside over the Narakas ("Hells" or "Purgatories"), and the cycle of rebirth in Buddhism.
==History==
===Ultraman Ace===
Yapool, an ancient creature from another dimension with similarities to Satan and Legion, was an extremely skilled being of many consciousnesses with a knack for creating biological creations known as Terrible-Monsters. 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 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 Ultra 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 a new alias, the and his strongest form, .
One day, Yapool for the first time schemed an invasion on their own hands without using Terrible-Monsters. They started off by sending an agent of them in disguise as an old man, manipulating children from around the globe by singing a hypnotic music and said the world will end. 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. Hokuto shot him but that 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. 
While Yapool miraculously survived his battle against Ace, he was left incapacitated for quite some time, clearing the way for other antagonistic aliens such as Alien Hipporit and Alien Steal to travel to the Earth and enact their own schemes. However, even with his giant body's destruction, Yapool's cells dispersed around the Earth and therefore led to multiple Terrible-Monster attacks in spite of his absence and allowing his plans to continue, even without him being present to direct them personally. To make matters worse, Yapool's agents remained active, and starting with Mazaron Man, a number of agents who had been entrusted Terrible-Monsters by Yapool would make their presence known during their superior's absence, intent on achieving the mastermind's goals in his stead. 
====Yapool Woman====
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 unleashed the real Verokron II to attack the city. The real Verokron II was eliminated by Ace afterwards as Woman Yapool's tricks were later foiled and was killed by Hokuto himself when he fired his gun at the fiend, as he fainted and was reduced to bubbles. But as he was about to report the dental clinic, the entire premise disappeared alongside Yapool's cadaver. 
====Alien Simon====
Though it seemed as if Yapool had once again died when Hokuto shot his Yapool Woman form, Yapool had cheated death once again, and had merely escaped to resume his plans to take over the world. After sending the next of his agents and their monsters to carry out his plans, followed by another monster of his own, the time was right for Yapool to enact his his grandest plan yet. 
Yapool took on the form of a juvenile Alien Simon - a race of aliens he had apparently fought and defeated in the past - as a disguise. With his disguise in place, 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, the strongest of his creations thus far, attacked the city. 
Yapool's disguise was convincing, as he even went as far to only speak in the language of the Simons, but later Yapool told Hokuto via specialized telepathy that he was the mastermind in disguise, and his true plan was to get his revenge on TAC, trick the children into losing their faith in Hokuto and Ace by forcing the former to kill Simon, and then defeat Ace once and for all using Jumbo King. Hokuto shot the Alien Simon, causing the children to lose their faith in him. They didn't believe Hokuto's words when he said that Yapool had communicated the truth to him through telepathy, as only the Ultra Brothers had this power. In spite of the risk of being unable to return to his human form, Hokuto revealed to the children that he was Ace's host, and transformed, regaining their trust. Ace faced off against Jumbo King, who was defeated, and Yapool's reign on Earth was seemingly ended. 
===Ultraman Taro===
Yapool reappeared in Ultraman Taro surviving his battle against Ultraman Ace, as . He was responsible for the first monster of the series, Oil Drinker, that appeared in episode 1, though Yapool himself did not appear. Remodeled Yapool made his first appearance in episodes 29 and 30, with his trio of "Remodeled" Terrible-Monsters.
Yapool hid himself in exile and created a space ship that not only allowed him to enter Earth's dimension, but also travel through space. After the death of Oil Drinker, he revived Bemstar, as Remodeled Bemstar. ZAT was alerted of the situation and tested a new type of giant buzz-saw on Reconstructed Bemstar trying to imitate Jack's Ultra Bracelet, but Yapool's modifications proved that it was not enough to defeat Re-Bemstar. Kotaro Higashi transformed int to Ultraman Taro appeared to battle Re-Bemstar but was defeated. When Re-Bemstar was being repetitively stabbed in the eyes by a young man Hachiro Umino, Yapool sent Remodeled Sabotendar to kill the young man. Ultraman Taro then returned to both of the Terrible-Monsters. Furious that Taro was still alive, Yapool "remodeled" Verokron II to take care of the situation only for all his Terrible-Monsters to be defeated. Yapool tried to retreat from Earth's atmosphere, but Taro used his Strium Beam on Yapool's ship, defeating him once again. 
===Ultraman Regulos===
Despite not making a physical appearance, Yapool was mentioned by Volcan, who had bargained with him in order to obtain a Baraba which he used against Ultraman Regulos during their final battle. 
===Ultraman Mebius & the Ultra Brothers===
In the year 1986, the ever plotting Yapool sent a new Terrible-Monster 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 Terrible-Monster, 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 Spacium and Metalium Beams 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.
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 ultimate 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.
Having escaped death, Yapool sought his revenge on Mebius by kidnapping Ryu Aihara and possess him in a plot to frame Mirai. His plan almost worked (sabotaged a GUYS aircraft) until Sakomizu appeared and foil his plot. Under Ryu's assurance, Mirai fired his GUYS Memory Display, forcing Yapool to exit and took over Vakishim before retreated. When Asami Fujisawa presented GUYS with a METEOR capable of sealing the dimensional portal, Yapool possessed her in hopes of disposing the device but realised too late that it was all a ploy to lure his Terrible-Monster Doragory. Yapool's dimension was sealed with Dimensional Dissolver in hopes of preventing him to attack Earth. 
====Service to the Emperor====
Several months later, he appeared to have unseal the portal and utilized Gadiba in possessing Red King within Tatara Island. Although fought by Mebius, Gadiba soon expelled under Yapool's orders, leaving Gomora (who borrowed the appearance of Red King) to deal with the Ultra. He would soon join the ranks of Dark Four Heavenly Kings, confidently being the first to left and attack Mebius in hopes of giving the Earth to Alien Empera. His first mission is by luring GUYS to outer space with a crystal missile and for Lunaticks to deal them while personally sending his revived Ace Killer to fight Mebius. In the middle of the battle, he assimilated Gadiba with Ace Killer into Mebius Killer, overpowering Mebius until he comes up with a new tactic; Mebium Dynamite. Once Mebius revert to Mirai, he kidnapped the Ultra and two other humans, Aya Jinguji and Mitsuhiko Hirukawa. 
He brought his targets to a dimension which appeared to be Tokyo in ruins. Seeing Hirukawa's irrational desperation to survive, he coerced the man to shoot both Aya and Mirai, ultimately exposing the latter as an Ultra in disguise. When Mirai refused to admit the ugly truth of humanity, Yapool engages in a battle against the Ultra and successfully weaken him. He shift his attention to Aya and blasted the area in front of her, nearly killing her. Encouraged by Seiji, Mebius' power and spirit were restored, and much to Yapool's surprise, he stood up once more, and assumed his Burning Brave form. This time, the tide of the battle turned, as Mebius went on an all-out attack on Yapool before dealing the finishing blow. His last words were that of informing Mebius that more foes, even stronger, would come, such as Deathrem, and Grozam. 
===Ultraman Mebius Gaiden: Ghost Rebirth===
Yapool was revived and possessing his creation, Mebius Killer. Yapool, along with Deathrem, Grozam, and Armored Mefilas (G) assault the Ultra Brothers in an attempt to reunite the Giga Battlenizer and Mechazam in an attempt to resurrect Alien Empera. However, their plan was foiled when Ultraman Mebius looses the Giga Battlenizer and Mechazam 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 Metalium Beam. 
===Mega Monster Battle: Ultra Adventure===
Long ago, the Yapools are driven to near extinction as a result of Alien Reiblood's actions. Although Reiblood had long perished, Yapool feared the possibility of his revival and made it their mission to track down and kill Reionics, as well as destroy their Battlenizers to prevent the spiritual alien's return. When Io Mikura and Pigmon were stranded on an unnamed planet, Yapool sends down Vakishim to hunt the boy. Seeing the Alien Pedan army protected him, Yapool contacted their mothership and promised to stay out of their affairs if Io is surrendered to him. However as they defy his threat, Yapool called Ace Killer back to his dimension when the robot suffered heavy damage. Alien Nackle, the Pedan's adversary in their war, contacted Yapool and asked for his cooperation in exchange for Io's life. Yapool agreed to this, as he not only granted Nackles a few of his Terrible Monsters, but also EX Tyrant that the two races created together. Yapool however didn't ended up participating in the fight.
In Mega Monster Battle: ULTRA MONSTERS, Yapool's role is more or less the same in his first appearance. However as he never established a deal with Nackle, he appeared after the lone alien's demise and sends down Ace Killer, Tyrant and EX Tyrant after the protagonist.
===Mega Monster Battle: Ultra Adventure NEO===
Despite knowing that Io and Vittorio's Gomoras had taken care of Alien Reiblood, Yapool sensed his revival as well and tracked down Kanegon's Battlenizer to the alien planet where he and Ai had stranded on. Yapool intercepted Kyrieloid and Grozam's fight by absorbing them into his pocket dimension, where he detained them from fighting and personally went to kill the two Reionics. Giant Yapool appeared before Ai and Kanegon, intending to kill the two and easily toyed Red King by levitating the monster airborne. But the Battlenizer unleashed a blue sphere that shoots fireball at him. Giant Yapool retreated to his dimension, realizing the terror behind that sphere before he exploded.
Collaborated with Alien Hipporit, another alien who also dreaded the Reiblood like Yapool, the two established the Space Alliance Army, consisting of aliens, monsters and Terrible Monsters from across the universe to band together and preventing Reiblood's return. Although they primarily target Reiblood and his EX Zetton, the army do not discriminate with other Reionics and would also resort to attack Ai Asama, Kanegon and Alien Keel Vittorio if given the chance. Yapool joins in the fight as Giant Yapool and like the rest of the army, they were obliterated by several Trillion Meteors. When Ai and Io confronted Reiblood/EX Zetton with Gomora and Red King, Reiblood responded by resurrecting the Space Alliance Army as his reinforcements. Ultraman and Ultraseven arrived just in time to even the odds, the former putting up a barrier to prevent the alliance army from advancing. With Reiblood/EX Zetton eliminated, the resurrected army had their spirits ascended to the Monster Graveyard.
In Mega Monster Battle: ULTRA MONSTERS NEO, Yapool's role is simplified to directly confronting the faceless protagonist and Kanegon after killing a trio of Alien Guts. Yapool demanded Kanegon's Battlenizer and despite the coin monster assuring them that Reiblood had long dead, the otherworldly beings made it clear that as long as Battlenizers are still around, Reiblood can still be resurrected. Kanegon then offer them to sell the device, but Yapool responded by fusing into Giant Yapool and bring out Vakishim and Ace Killer. The protagonist fight all three of them. Giant Yapool then falls to the ground, still aiming for the Battlenizer before his body exploded.
===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 returned with Vakishim in Ultraman Ginga S episode 5, this time inside his Giant Yapool body for most of his appearance.
Yapool appeared when Vakishim was fighting Ginga. Angry at Android One Zero for using Vakishim's Spark Doll without permission, he took control of the Terrible-Monster away from the android and cast her out of the Lived Doll. He then sent the Terrible-Monster back to his home dimension and told One Zero and Exceller that he will deal with Ginga, knowing about the Chibull'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 Terrible-Monster.
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 Terrible-Monster 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 Metalium Beam. 
===Ultra Fight Victory===
Yapool returned in Ultra Fight Victory as the one responsible for sending the Terrible-Monster. He somehow survived his destruction during his previous defeat at the hands of Ultraman Ginga.
He was first seen studying Ultraman Victory's Ultlance 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 Terrible-Monster have been killed by Victory and Shepherdon, 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 Shoot, and Punch Laser respectively at the Terrible-Monster. Yapool then grew in size and joined the Terrible-Monster 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 Fusion Shoot. In his last act, Yapool gives in his own energy to revive Juda. 
===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. 
===Ultraman Z===
As proclaimed by Baraba, Yapool's grudge had not ceased, and his Terrible-Monsters continued his mission while he was still yet to revive from his most recent death. Though Yapool remained unseen throughout the remainder of the series, the existence of his dimension became a major plot point, as the energy held within it was utilised by the D4 and D4 Ray weapons, which Celebro sought to obtain as part of his Civilisation Self-Destruction Game with the aim of exterminating humanity.
===Ultraman Decker===
Yapool, in the form of a single individual Yapool Man, managed to come from a different dimension and found Agams just as he was spotted by a TPU patrol. He protected the alien before the squad could do anything further, blasting them away. Yapool decided to lend his assistance to Agams as they both had a hatred for the light of the Ultramen and wished to destroy them all, lending an Aribunta to carry out a plan to exterminate Ultraman Decker.
While Aribunta brought destruction to the city, Yapool and Agams waited in anticipation for GUTS-Select to sortie. Once they had the opportunity, Agams brought Kanata into his own dimension and hoped to get rid of him there while Yapool appeared and disguised as Kanata, albeit with irregular behavior. He led Soma Ryumon and Ichika Kirino closer to Aribunta and hoped they would get killed there, dropping his disguise to mock them. Yapool reappeared again once Agams had been defeated and ejected out of Terraphaser, and took on Agams' form to trick Decker into protecting him from Aribunta's explosion, exploiting Kanata's wish from Decker Asumi to save Agams. Yapool then took the opportunity to open a dimensional hole that sent Decker to space. After Kanata escaped, he was attacked by the Spheres in space but was rescued by Ultraman Trigger, who assumed his human form and brought Kanata to a Sphere-infested TPU base on the moon. Yapool attacked Kanata and Kengo by activating the Zomborg Soldiers to fight for him, but he eventually was assimilated by the Spheres, leaving him weakened and disoriented. Decker and Trigger then finished Yapool off using their signature Ultra Beams when they had the chance.

===Ultraman Hit Song History: New Hero Chapter===
Yapool returns in this special track to attack Ultraman Zero. He first lures the Ultra into his dimension and bombards him with attacks. However, the Heisei Ultras arrive and begin assisting Zero to fight back against Yapool. 
===Ultraman F===
Giant Yapool appeared in this novel as one of the many antagonists.
Through a dimensional crack created by Soso via Clone Bullton, Yapool emerged on Nagoya, Japan, having fused to his Super Beast U-Killersaurus. He demanded an Ultraman for him to fight and thus Hayata (who was separated from Ultraman) appeared. Although declared as a "remnant of the original Ultraman", Yapool was quick to dismiss the former Ultra Host and held Ultraman F as a hostage. F retaliated by escaping and destroy both alien and Super Beast. 
===Ultraman Blazar Spectacle Live in NYCC 2023===

Blazar, using the Tilsonite Sword, managed to defeat the two aliens, though Bazanga then appeared. Earth Garon and Blazar teamed up to take down Bazanga, only for Infinite to appear. Yapool Rainbow Lotus and Nodachi Zamsher returned, pledging their alliance to him. However, Infinite attacked the pair and absorbed their energy, destroying them.

==Trivia==
*When in his Giant form, Yapool reuses Mummy Man's roars.
**The Strange Old Man disguise uses the Toho's Frankenstein's roar from Frankenstein vs. Baragon.
*Yapool is the first major antagonist in the Ultraman Series to be recurrent and overarching in his debut series, with his role in the story of Ultraman Ace playing a major role in its progression and outcome, rather than him simply being a final opponent for the Ultra to battle, as in the case of Pandon, Alien Bat or Zetton.
*Yapool is said to be part of Jumbo King in Pictorial First Volume 2002.
*In aftermath of his appearance in Ultraman Ace, Giant Yapool was used as an attraction suit until its head component deteriorated, causing a new head to be made for his return in Ultraman Taro. A magazine at that time explained that Giant Yapool was revived and had to perform reconstructive surgery to recover from his last battle with Ace. However, the result was crudely done which resulted in a deformed head, resulting in a metallic headpiece being installed to replace the original.
*While not mentioned in Ultraman Taro, a 1990 magazine stated that Yapool collaborated with Alien Empera during his presence, with Reconstructed Bemstar being one of the products of their collaboration.
*His appearances in Ultraman Taro established Giant Yapool as the default form for Yapool.
*Since Giant Yapool only fought Ace in his own dimension, none of TAC's documents mentioned him, as revealed in Ultraman Mebius.
*Originally, Giant Yapool would have been given a redesign in Ultraman Mebius & the Ultra Brothers. 
*Yapool being inside Vakishim's body in Ultraman Ginga S is a tribute to the Terrible-Monster's appearance in Ultraman Ace where it was a form of Yapool.
**His defeat by the Metalium Beam is a homage to his debut series; however, Yapool was able to survive that attack back then.
*An Ultraman Connection article referred to the Yapool that appeared in Ultraman Blazar Spectacle Live in NYCC 2023 as simply "Rainbow Yapool".https://news.ultramanconnection.com/ultraman-nycc-2023-live-spectacle-what-happened/
