Doctor Ub'x is a H'lvenite, a rodent-like alien originating from the planet H'lven in Space Sector 1014. Possessing great intelligence and an equally great desire for power, Ub'x leaves his homeworld and creates a powerful military force known as the Crabster Army that conquers most of the planets in the sector. Turning his attention to his homeworld, Ub'x easily conquers H'lven and sentences the leader of the resistance, Ch'p, to death. Ch'p is visited by one of the Guardians of the Universe, who gives him a Green Lantern power ring. Using the ring, Ch'p drives Ub'x's forces from the planet.^[4]

Ub'x creates the Sucker Stick, a device designed to match the power of a Green Lantern, just before the events of "Crisis on Infinite Earths". Realizing that the timeline is being rewritten, Ub'x uses the Stick to transform himself into energy, which prevents him from being erased from history.^[4]

Ub'x follows Ch'p to Earth. Once he defeats the Green Lanterns, Ub'x regains his physical form and prepares to kill Ch'p. However, he relents after realizing that Ch'p is among the few individuals who remember the original, pre-Crisis timeline.^[4] Ub'x and Ch'p form a truce and eventually became friends.

Ub'x relocates to Africa, where he experiments on wildlife to create a species similar to the H'lvenites. Accompanying Ch'p on a mission to the 58th century, Ub'x discovers that his experiments have prospered and remains in the future to watch over them.^[5]

Ultivac is a giant robot built by scientists Felix Hesse and Floyd Barker, who went rogue against its creators.

Ultraa is a DC Comics character, originally the first superhuman on Earth Prime. The original first appeared in Justice League of America #153 (April 1978), he was created by Gerry Conway and George Tuska. The current Ultraa first appeared in Justice League Quarterly #13 (Winter 1993), written by Kevin Dooley and drawn by Greg LaRocque.^[6] A new version of Ultraa appears in Grant Morrison's The Multiversity project.^[7]

Ultraa's origin is very similar to Superman's, in that he was born on an alien world and sent to Earth to escape its destruction. He landed in the Australian Outback and was raised by Indigenous Australians. Ultraa joins the Justice League of Earth-One, but they turn against him following an incident where he uses a ray gun to make the members of the League and the Injustice Gang apathetic.^[8][9]

As a result of their second encounter with Ultraa, the League imprisons him in a "stasis cube" prison of Superman's design. He is later released by an alien hive mind known as the Over-Complex.^[10] A dispirited Ultraa adopts the civilian guise of Jack Grey and becomes a busboy. He is manipulated by Joe Parry, a down-and-out former opponent of the Justice League, but a heart-to-heart talk with Hawkman convinces him to break off the attack. Ultraa subsequently decides to move back to Australia.^[11]

Following Crisis on Infinite Earths, which reboots the continuity of the DC Universe, the original Ultraa is retconned out of existence. In Justice League Quarterly #13 (1993), Ultraa is reintroduced as a native of Almerac and the betrothed of Queen Maxima.^[12] Ultraa later appears as a member of the League Busters in Justice League International.^[13]
