Created as part of Weapon Plus's Super-Sentinels by employing artificial evolution and nanosentinel technology, they are labeled as exact copies of each other, an anomaly that was fixed by picking Ultimaton for further development inside of The World.

Ultimo
Ultimus
Ultimus was created by Gerry Conway and John Buscema, making his debut in Thor #209 as Demon Druid, while he made his debut as Ultimus in Wonder Man #7.The Kree known as Ard-Con was a member of the Kree Eternal sub-race created by the Celestials. He with the other Kree Eternals travelled through space, eventually coming across Earth 4000 years ago. The Celts of Earth mistook the Kree Eternals as deities and soon all Kree Eternals left Earth except Ard-Con who stayed on Earth for a millennium, but was then imprisoned by the Deviant Tantalus. He also encountered Odin once, claiming that his name brought back memories, but also thought that Odin had died. He was then accidentally freed by Thor when the latter used Mjölnir to turn into Donald Blake. Once free, he started wreaking havoc across the streets and knocked Thor unconscious. He was then apprehended by the British Army and Thor again, but stopped fighting when Thor realized that Ard-Con was trying to reach a portal at Stonehenge to leave Earth. After that, Ard-Con successfully departed Earth.
Ard-Con was unable to find his people, so he returned to Earth via a portal created by two tourists and the hero Meggan, who were under the influence of the Eternal. Shadowcat intervened and freed Meggan along with tourists. Ard-Con then broke into Darkmoor Nuclear Research Facility where he recreated a nuclear facsimile to use it at Stonehenge and finally reunite with his people. However, the Excalibur intervened and stopped Captain Britain from fighting Ard-Con, while Kitty opened a portal to Ard-Con's people and apologized to him. This proved to be successful, but upon arriving at his home, he was approached by the Supreme Intelligence who informed Ard-Con that he was the last surviving Kree Eternal. Then Ultimus, under the order of the Supremor, joined the Starforce.
He, along with rest of the team, were sent to capture the Avengers, since they had infiltrated Kree-Lar. They were successful in capturing the Avengers, however, the current rulers of the Kree, Ael-Dan and Dar-Benn, decided to execute both teams by locking them into a force field. Deathbird killed the emperors, which allowed the Supreme Intelligence to regain control of the Kree Empire. He then sent the team against the Shi'ar as a retaliation against his attempted assassination by the Shi'ar Empire. They teleported into the Shi'ar palace with Ultimus dispatching Earthquake and attacking Lilandra Neramani. However, Starfox distracted Ultimus long enough for Lilandra to strike Ultimus back. After being captured, they were sentenced to death by the Shi'ar, but things became complicated as it was revealed that the Shi'ar counselor Araki was replaced by a Skrull. Ultimus was released by Lilandra under her order to report about the Skrulls' plans. The Starforce was then integrated within the Imperial Guards and under the orders of Deathbird they attacked Quasar with his allies for their intrusion in Shi'ar space. After the Kree regained their autonomy, all of the Starforce members became defectors.

Ultragirl
Ultragirl is an American comic book superhero created by Barbara Kesel and Leonard Kirk, who first appeared in Ultragirl #1. As one critic described, "She was a clever … modern riff on Supergirl, basically 'What would Supergirl be like if she debuted in the mid-1990s in the Marvel Universe?'"Suzy Sherman is an aspiring model who, over the course of a few days, grows several inches, develops the physique of a bodybuilder, and acquires superpowers. She discovers that she is a mutant Kree warrior, born Tsu-Zana. She helps the superhero team New Warriors defeat the villain Effex. Her powers include flight, super-strength, multi-spectral vision, and a healing factor.
Ultragirl is a member of Captain America's Secret Avengers during the superhero civil war. She later joins the superhero training program the Initiative and enters a romantic relationship with Justice. She and Thor Girl become the Initiative heroes assigned to protect Georgia, with Carol Danvers/Ms. Marvel having been so impressed by Ultragirl's development that Danvers bequeaths Ultragirl her former Ms. Marvel costume.
During the Secret Invasion, the Skrull Dum Dum Dugan activates all the sleeper agents in the Initiative, causing Ultragirl and Thor Girl to fight each other out of suspicion. When the Skrull Kill Krew arrives on the scene, 3-D Man confirms Thor Girl is a Skrull, and he and Gravity kill her with her own hammer. She later is forced to give up the Ms. Marvel costume after an attorney informs her that its intellectual property rights are owned by the Avengers, at this time temporarily under the control of the villainous Norman Osborn. After saving Justice from the deranged Thor clone Ragnarok, Ultragirl leaves the Initiative to join Justice's revamped New Warriors team.

Unspoken
The Unspoken is a supervillain appearing in American comic books published by Marvel Comics. He is the cousin of Blackagar Boltagon, and was once the king of all Inhumans before he was forced into exile. The Unspoken first appeared in The Mighty Avengers #27 and was created by Dan Slott, Khoi Pham, and Christos Gage.Originally, the Unspoken was a just ruler to the Inhumans. However, fearful that it would corrupt his people, he decided to steal the Slave Engine, his people's greatest weapon, along with the Xerogen Crystals it utilized and buried them somewhere in Tibet. After refusing to reveal the Slave Engine's location, he was then challenged to a duel by the heir to the throne, a young Blackagar Boltagon. Despite being by far the strongest of the Inhumans, moving the Slave Engine had weakened the King which led to his defeat at the hands of Blackagar and his friends. His final stipulation was that his deeds be remembered, but Black Bolt had a crueler fate in mind: the King, his deeds, and the Slave Engine itself, were written out of Inhuman history. From that day on, he would be remembered only as a Bogeyman to frighten small children, his name forevermore "unspoken".
He was later recovered by the Alpha Primitives, who cared for their fallen king. Realizing his mistake, the Unspoken plotted to return and reclaim his throne, cultivating the Xerogen Crystals, only for Attilan to rise into the sky. Cheated of his redemption and later learning of the silent war between the Inhumans and United States of America, the Unspoken decided to change his plans and unearth the Slave Engine using it to conquer Earth, by transforming all humans into Alpha Primitives. The Unspoken was defeated when the chronal ray on board the Slave Engine that accelerated the growth of the Xerogen crystals was used against him, aging him to the point where he was too weak to carry on fighting. The heroes then permitted the Alpha Primitives to allow the Unspoken to return to his cave to live out the rest of his days.
The Unspoken is the living embodiment of Terrigenesis itself. He is capable of altering his form in any way he desires, and can give himself a wide number of abilities, such as mass manipulation and energy construct manifestation. To maintain his powers, he needs to absorb Terrigen Crystals.
