List of Marvel Comics characters: U
Ultimaton. Ultimaton, also known as Weapon XV, is a living weapon created by the anti-mutant supersoldier program Weapon Plus. The character was created by Grant Morrison and Chris Bachalo, first appeared in "New X-Men" #143 (Aug. 2003). Ultimaton escapes from the Weapon Plus facilities, fights the X-Men and is destroyed. He is later resurrected to guard a child clone of Apocalypse. Ultimus. Ultimus (Ard-Con) 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 Mjolnir 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 in order to depart Earth. After that, Ard-Con successfully departed Earth. Ard-Con was unable to find his people so returned to Earth thanks to 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 and also allowing Rachel Summers getting some knowledge about his people. Ard-Con then broke into Darkmoor Nuclear Research Facility where he recreated a nuclear facsimile in order to use it at the 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, however, upon arriving to 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. Thankfully, 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, 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. In "What If? Avengers lost Kree-Shi'ar war", this version of Ultimus fought against the Avengers and the Imperial Guards, but was killed by the Imperial Guard, Flashire. Ultimus is a major villain in "Marvel Strike Force". Ultragirl. Ultragirl (Suzanna Sherman, or Tsu-Zana) is a American comic book superhero created by Barbara Kesel and Leonard Kirk, who first appeared in "Ultragirl" #1 (Nov. 1996). 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 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 tome 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. Following two brief appearances, Ultragirl took part in the "Fear Itself" storyline when she teamed with the genuine Thor Girl and confronted Prodigy. She later helped the Young Avengers battle the parasite being Mother. She is not to be confused with the character Ultragirl from Megaton Comics. Union Jack. Joseph Chapman. Union Jack will make a reappearance as a member in the new  UK marvel superhero team The Union. Unspoken. The Unspoken is a fictional supervillain appearing in American comic books published by Marvel Comics. He is the cousin of Blackagar Boltagon (Black Bolt), 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 N. 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 on the planet into  Alpha Primitives. In the 21st century, the Unspoken was detected in Tibet. G.R.A.M.P.A. interpreted this as a possible alliance between communist China and the Inhumans but were unable to identify the Unspoken. Therefore, they called in Quicksilver, an expert on the Inhumans, and U.S. Agent. The former recognized the Unspoken and advised that they call all the Avengers teams (consisting of the Mighty Avengers, the New Avengers, the Young Avengers, the Avengers Resistance, and even the Dark Avengers) to stop him. Unfortunately, even the joint forces of the New Avengers, Avengers Resistance and Mighty Avengers failed to stem the tide . Most of their force were mutated by the Xerogen Mists, before the Wasp arrived. They both dueled each other at massive sizes. Wasp called him pathetic, for wallowing in his own misery for his mistakes and not learning to move on. 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. During the "Inhumanity" storyline, the Unspoken resurfaced and arrived at New Attilan. Due to Black Bolt missing at the time, the Unspoken proposed to Medusa and tried to cover for his missing brother. Medusa refused the Unspoken's offer and had him incarcerated in the dungeon. The Unspoken soon broke free from his imprisonment and headed to New Attilan's catacombs. It is here that the Unspoken starts looking for Terrigen Crystals in order to replenish his powers. Despite the intervention of Medusa and Gorgon, the Unspoken defeated them and reclaimed the throne. The newly transformed  Inhumans later helped the Inhuman Royal Family to fight the Unspoken managing to steal the Terrigen Crystals from him. Upon his defeat and being deprived of the Terrigen Crystals, the Unspoken was reimprisoned in the dungeon. 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. Unuscione. Carmella Unuscione is a mutant, a member of Magneto's Acolytes. The character, created by  Scott Lobdell and Brandon Peterson, first appeared in "The Uncanny X-Men" #298 (March 1993). The character has the ability to generate a tangible field composed of bioelectrical-charged psionic energy around herself, forming an exoskeleton. She is portrayed as one of the more fanatical and violent members of the Acolytes, who often come into conflict with the X-Men. When Avalon, the Acolytes' base of operations, is destroyed, she uses her power to protect her teammates and the X-Man Cyclops. The former enemies cooperate to survive without resources while Professor X and Amelia Voght struggle to find their  teammates' whereabouts. Unuscione and the other Acolytes agree to turn themselves over to government custody, but later escape. Unuscione returns to action with the Acolytes as they attack the X-Mansion following the M-Day. Professor X is placed in the Acolytes' care after he is critically injured by Bishop. Xavier convinces Exodus to disband the Acolytes, and Unuscione and Joanna Cargill move to Utopia. Other versions of Unuscione. In the alternate "Age of X" reality, Unuscione is known as Stand-Off. She is a member of the Force Warriors, a group of psionic mutants who protect "Fortress X", the  last known mutant stronghold, by collectively channeling their powers to generate and reinforce a massive psionic shield. Unuscione in other media. Unuscione appears in the two-part episode "Sanctuary" of the animated series "X-Men", where she is a devoted and passionate follower of Magneto and his beliefs. In the episode "Graduation Day," Unuscione is among the mutants on Genosha that want Magneto to lead them. Ev Teel Urizen. Ev Teel Urizen is a fictional character appearing in American comic books published by Marvel Comics. It was created by writer Mike Carey. Ev Teel Urizen first appeared in "" #197 (May  2007). Urizen is a mummudrai, an energy-based mental parasite. Urizen existed harmlessly dormant in its host, the Shi'ar Ul'var Urizen, until Shi'ar scientists extracted it to use as the basis for a superweapon, Hecatomb, designed to consume the minds of a planet's entire population. The Shi'ar lost control of Hecatomb and it pursued Urizen, which it identified as part of itself. Detecting Charles Xavier's psychic energy on Earth, Urizen traveled through space for centuries to reach him, followed by Hecatomb. On Earth, Urizen entered the mind of the comatose Regan Wyngarde, and remained with her after she  regained consciousness and helped defeat the Children of the Vault. Still hidden, Urizen risked exposure to protect Regan during a subsequent conflict with the villain Pandemic. Regan eventually detected Urizen and expelled it from her mind. Urizen offered to bond with the powerful mutant Cable to fight Hecatomb. Suspicious of Urizen's motives, Cable initially refused; he reluctantly agreed only after Hecatomb attacked Earth and proved as powerful as Urizen had warned. Hecatomb was able to separate Urizen from Cable, but not before they used their combined powers to wake the comatose Rogue. Urizen spent its last moments in terror  as Hecatomb consumed it. Rogue then arrived and, her powers augmented by Pandemic's "Strain 88" virus, absorbed the 8 billion consciousnesses Hecatomb contained, destroying it. Subsequently, Rogue contained the memories of all those minds, but Urizen and its memories were never specifically mentioned.
