==History==
===Ultraman Ace===
Ace Killer was a creation of Yapool in an attempt to kill Ultraman Ace. By luring the Ultra Brothers onto a desolate planet and forcing Ultraman Ace to battle the Terrible-Monster, Baraba on Earth. Ace Killer was released and absorbed the powers and weapons of the Ultra Brothers. With their power, Yapool released a robot replica of Ultraman Ace to demonstrate Ace Killer's power. Withstanding a Metalium Beam, Ace Killer used a barrage of Ultraseven's Emerium Beam and Ultraman's Spacium Beam to weaken the robot until it destroyed it with a variation of Zoffy's M87 Beam.
Eventually, Ultraman Ace returned to try and rescue his brothers but was ambushed by the powered-up Ace Killer. With the Ultra Brothers' powers, Ace Killer easily overpowered Ultraman Ace until the Ultra Brothers used the last of their energy to replenish Ultraman Ace. With their combined energy, Ultraman Ace hurled a concentrated ball of their energy (the attack known as Space Q) at Ace Killer, destroying Yapool's weapon against him and releasing his comrades. 
====Trivia====
*Designer: Yoshio Suzuki
**Suzuki also said that Ace Killer is his favorite Ultra Kaiju to design, but has no idea on how did he manage to design his head.
*Voice actor: Frank Welker (Fighting Evolution only)
*Original magazines claim that Ace Killer is a cyborg, as it was originally a corpse from a Planet Golgotha that Yapool took and zombify it. Eventually after Ultraman Mebius, later Ace Killers are written as robots instead.
*This is the only series in which Ace Killer carries his sai, series-wise. In video games, he uses it as a weapon.
*Interestingly, in the Ace manga by Matsuhisa Akihito, Ace Killer does not appear at all, his role and name being taken by Baraba instead.
*Ace Killer was one of the monsters and aliens that made up Belyudra's neck in Mega Monster Battle Ultra Galaxy: The Movie.
===Andro Melos===
The magazine series of Andro Melos revealed that the original Ace Killer was resurrected by the Gua Army into and conscripted into their force of the remodeled monster army.
In June 1981 issue, the Ace Killer fought against Zoffy at some point after Ultraman 80 finished his mission on Earth. The Ace Killer threw Zoffy into a black hole and was killed by Andro Melos, who happened to be the disguised Zoffy.
In February 1982, Ace Killer was revived alongside the other remodeled monster army. The entire team trap Melos and Andro Wolf inside a flaming vortex, but the two were able to escape and defeat the entire army.
====Trivia====
*According to Shinichi Wakasa, the photography for Remodeled Ace Killer was taken in Yorii of Osato District in Saitama Prefecture.https://twitter.com/shinichiwakasa/status/1314424269766451200
*In the magazine picture where Ace Killer attacked Melos, its appearance was only rendered to its legs. Ultra Super Legends further compensated and expanded his role and reason for hunting Zoffy.
===Ultraman Mebius===
Ace Killer returned in episode 43 of the series, Ultraman Mebius as Mebius Killer. In this series, Yapool created a second Ace Killer and used it as a weapon to battle Ultraman Mebius.
====Ace Killer====
Mirai had gone on a walk in the park with a girl he'd met, but Yapool was spying on them, disguised as a human once more. He held a clutch of balloons 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 balloon with gold stripes into the sky. The balloon 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 the girl, 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.
====Mebius Killer====
After Gadiba transformed Mebius Killer, Yapool ordered Mebius Killer to first use the Mebium Shoot; placing his left palm over the green pendant on his right forearm, Mebius Killer charged his hands with energy and performed the Mebium Shoot. 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 Shoot, 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 Burst. 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 girl 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. Unfortunately despite its destruction, Mebius Killer fulfilled its purpose to exhaust Mebius, allowing Yapool to kidnap Mirai, Aya, and Hirukawa into his dimension. 
====Trivia====
*The new suit is designed by Hiroshi Maruyama, based on an old picture of Ace Killer from his time in Ace. Despite looking almost identical, Maruma admitted that his redesign involved several minor alterations.
===Ultraman Mebius Gaiden: Ghost Rebirth===
Mebius Killer returned as a body possessed by Yapool in Ultraman Mebius Gaiden: Ghost Rebirth as part of the assembled Dark Four Heavenly Kings. To denote his revived status, he is labeled as 
The Heavenly Kings assaulted the Ultra Brothers in an attempt to reunite the Giga Battlenizer and Mechazam in an attempt to resurrect Alien Empera. However, their plans are foiled when Ultraman Mebius loses the Giga Battlenizer and Mechazam sacrifices his life to keep The Emperor from being revived. In the end, he battles Ace and is destroyed by his Metallium Beam. 
====Trivia====
*Voice actor: Ryoichi Tanaka
*As stated at the cover of the show's DVD jacket, Yapool was meant to physically return but due to his suit being used in an outside attraction at the time, only Mebius Killer was left available and this forced the filming crew to come up with the excuse of Yapool possessing the body of his creation.
===Mega Monster Battle: Ultra Adventure===
Ace Killer was utilized by Yapool to threaten the Alien Pedan into surrendering Io Mikura, then was forced to retreat when they retaliated with King Joe Black, who managed to destroy its left arm. By the time Ace Killer joined Alien Nackle's Terrible-Monster army on Planet Pedan, its left hand was given a pincer claw. It was defeated by Io's Gomora, resulting with its inner machinery spilled out from breaking apart.
In Mega Monster Battle: ULTRA MONSTERS, Ace Killer and Tyrant are assigned to attack the protagonist after they killed Alien Nackle and his Black King.
===Ultraman Zero Gaiden: Killer the Beatstar===
Ace Killer returned as a mechanical replica built by Beatstar, designated as part of his Mecha Robot Army.
In part 1 of the special, after Gomora destroys a Legionoid Beta, Ace Killer (as well as Inpelaizer and King Joe) appear and together with the team up and beat down Gomora, forcing the monster back into Rei's Battlenizer. Shortly after, the Ultimate Force Zero arrives on the scene and battles the robots. Glenfire battles with Ace Killer and eventually destroys the robot by pile-driving him into the ground. 
====Trivia====
*Although it was built as "Ace Killer", supplementary magazines such as 2013 All Monsters Photobook claims that Ace Killer (BS) also bears the data of Mebius Killer, hence explaining the Mebius Brace on his right wrist.
===Ultraman Ginga===
Ace Killer and Kabuto the Killer were participants of the Dark Spark War turned into a Spark Doll by Dark Lugiel.
In episode 7, Ace Killer along with many other Kaiju and aliens are seen cheering on Ginga as he fights Dark Galberos.
In a couple of shots of the series, Ace Killer and Kabuto the Killer could be seen in Dark Lugiel's collection along with Deathfacer, Ghighi, Gatanothor, Birdon, Goldras, Alien Babarue, Gan-Q, Dada, Mecha Baltan, Alien Hipporit, Twin Tail, Mochiron, and a lot of other monsters and aliens.
It is assumed that after Ultraman Ginga defeated Dark Lugiel, they traveled back into space to return to Yapool's dimension, having regained their original forms.
===Ultra Fight Victory===
Ace Killer was the guard of a captured Ultraman Ginga, on orders from Yapool on Satellite Golgotha. He then dueled Ace there when he came to save Ginga. They were an even match for the most. After Ace launched the Ultra Guillotine attack, Ace Killer was thought he finished off. However, the Terrible-Monster survived and debuted his KillerTrans as being reintroduced by his master as Victory Killer. He summoned his new EX Red King Knuckle and struck Ace down to the surface with it. He then summoned the King Joe Launcher and fired at Ace, but the Ultra summoned his Ultra-Neo Barrier to deflect the energy bullets. Victory Killer then attacked Ace from behind, summoning his Eleking Tail, and defeated Ace by striking him with it many times. He was about to finish off Ace when Ultraman Victory showed up, used his Knight Timbre to transform into Victory Knight, and began to fight him. When the latter summoned his Sadola Scissors, Victory became shocked by this and Yapool explained that he studied the Ultlance and used them to modify the robot to become Victory Killer.
While Victory was kept busy with the new and improved robot, Yapool summoned Lunaticks to kill Ginga. Victory then decided to use the Knight Timbre to bring Shepherdon back to life, the process temporally knocked away Victory Killer. Victory Killer then got back up, summoned his Gudon Whip and fought Victory again until the knight slashed him across the chest with a glowing sword twice and finally finished him off with the Knight Victorium Shoot while Shepherdon finished off Lunaticks with his Victorium Flash. 
====Trivia====
*KillerTrans voice actor: Tessho Genda
*For this appearance, Ace Killer had his Mebius Brace removed so that he looked identical to his first appearance.
*The KillerTrans props were reused from Ultraman Victory's, while the end part used to connect Victory's arm was recolored to match Ace Killer's color scheme.
*Unlike previous incarnations, all of Victory Killer's KillerTrans were used on the same arm as the Ultra it was modified to copy, as opposed to being on the opposite arm (possibly due to Victory Killer's large claw on its left hand.).
===Ultraman Geed===
Ace Killer's Kaiju Capsule is used by Kei Fukuide as a component of Thunder Killer.

===Ultra Super Legend===
The Ultra Super Legend manga portrays the Remodeled Ace Killer in the same way as the magazine version of the Andro Melos. However, its only scene was throwing Zoffy into the black hole and defeated by Andro Melos (also Zoffy adopting a new identity). The manga also expands its sole agenda to assassinate the Ultra Brothers one by one.
====Trivia====
*In Shinji Imura's version of the manga, Remodeled Ace Killer is capable of speaking in perfect sentences and is willing to use dirty tactics such as putting hostages in line. Its sole appearance here was to cover up its obscure appearance in the magazine of a similar story.

In the second live stage, an enhanced Ace Killer was sent to Earth alongside Verokron. In addition to all four Ultra Brothers' finishers from Ace, he can also manifest Jack's Ultra Lance and Taro's Strium Beam. In the climax of fighting the Ultra Brothers, Ace Killer's limbs transform to resemble U-Killersaurus.
===Mega Monster Battle: ULTRA MONSTERS===
The Ace Killer, Tyrant, and Vakishim were sent by Yapool to attack Io Mikura and destroy his Battlenizer. As with all three monsters, he was killed by the player's choice of card.

In the Galaxy Saga mode story, Yapool created as an assassin sent to modify history. Kabuto went into the past where his first incarnation's fight with Ultraman Ace took place in Planet Golgotha and successfully crucify the Ultra. 
====Trivia====
*Voice actor (Kabuto the Killer): Ryoichi Tanaka
*Kabuto the Killer was a fan redesign of Mebius Killer created as part of a contest for Bandai's Toyline. In contrast to his original appearance, Kabuto the Killer has crab-like claws and his body design resembles that of a Samurai.
===Televi-kun Ghost Rebirth===
Instead of Mebius Killer, Yapool created Kabuto the Killer as his new body to operate and leads an army of Inpelaizers to capture the Ultra Brothers. Using the stolen powers, Kabuto merged them into Space Q and hurl it towards Taro, but the latter used his training of Ultra Horn with his father to absorb the attack and created the Cosmo Miracle Dynamite to defeat the armored robot. With Deathrem, Kabuto leads an army of Terrible-Monster to fight the brothers. Upon his defeat, the Giant Yapool reveals himself.
====Trivia====
*Instead of simply being a possession, Kabuto the Killer acted as if he is a living shell/disguise for Yapool and nothing more.
===Ultraman Belial THE STAGE Super Strongest! Belial Galactic Empire===
In a stage show taking place a day before Ultraman Zero : The Revenge of Belial, Mebius Killer accompanied Darkgone under Yapool's orders to enslave Belial as his minion. Unfortunately, Mebius Killer was stabbed by Darkgone's Gone Blade when he becomes interested in joining Belial's forces.
===Ultraseven Fan Meeting: Ultra Hero Show===
In one of the stage shows held during a Dan Moroboshi meetup eventhttps://youtu.be/gVecWtDe5mY, an Alien Raybeak by the name of Dan comes to Earth in search of parts to complete his peace-keeping robot (a pun on the literal translation of the word "peace") and in the process, ropes Ultraman Orb into helping out.
Dan makes Orb don an armor which first helps him out in defeating Chandlar by granting him a power boost, but this eventually turns out to be an energy-draining device to power Pisuke, now known as . On top of the powers of Ace Killer, Mebius Killer, and Victory Killer, Orb Killer was also granted the abilities of Ultraman Orb Hurricane Slash, alongside the , a copy of the Orb Slugger Lance.
Afterward, it was revealed that Yapool was possessing Dan all along, who then takes control of Orb Killer. However, through the combined efforts of Ultraman Orb, Ultraman Ace, and Ultraseven, Orb Killer was eventually beaten.
===6 Ultra Brothers THE LIVE -Featuring Zoffy-===
Yapool sent Victory Killer to defeat Ultraman Victory Knight. Using KillerTrans, Victory Killer obtained the Shepherdon Saber and fought Victory while utilizing the Ultra Brothers' abilities whenever Yapool commanded it. Yapool then revealed that this Victory Killer possessed the abilities of many more Ultras through the hatred that had been amassed within the cells of Yapool that made up the Terrible-Monsters, using Ultraman Geed Solid Burning's Strike Boost to demonstrate. Deciding that its name no longer fit, Yapool decided then to rename Victory Killer to . Yapool boasted that as long as the Ultras continued to fight him, his data on them would only increase. In response, Victory Knight declared that Yapool's arrogance was his greatest weakness and that he would never overcome the bonds between Ultras. Ultimate Killer then used a Victorium Slash, which Victory dodged before slamming his Knight Timbre into the ground to hit his enemy with a shockwave, allowing him to escape.
Later, Ultraman Ace and Victory fought Ultimate Killer and various other monsters sent by Yapool, and were in trouble until Zoffy arrived and reminded Ace of his Ultra Guillotine, which he used to knock some of their opponents away. Zoffy then summoned the Galactic Federation to aid them. Victory confronted Ultimate Killer and Alien Kettle simultaneously, eventually stealing back the Shepherdon Saber. By dual-wielding his two swords, he succeeded in defeating Ultimate Killer and Alien Kettle. 
====Trivia====
*Ultimate Killer has the same appearance of the original Ace Killer, including its green, jewel-like eyes.
*When speaking about the new abilities that Ultimate Killer possessed, images of Orb's fight against Aribunta, Geed's fight against Thunder Killer, Rosso and Blu's fight against Aribunta and Victory's fight against Vakishim are shown.
