Personality[]
Similar to his main timeline counterpart before his reforming, this Nolan follows the general nature of most Viltrumites. Because he never experienced his son's rebellion against him and feelings of regret, Nolan continued with his ruthlessness and loyalty to the Viltrum Empire, committing countless amoral acts for the Viltrum Empire to conquer planets. Due to his race's near-immortality, immense power, and extremely advanced technology, he sees many other races as being weak and inferior. Arrogantly believing it is his duty to bring order to other societies for the greater good, he will conquer them, and if they resist, they are subjugated violently. Despite the shameless and indifferent way operates for the Viltrum Empire, he truly believes that is doing the right thing, viewing order and dominance as the same as peace and prosperity. His ruthlessness is seen with dismembering The Immortal quickly. He will indifferently kill those who defy the Viltrumite rules and likewise indifferently proclaims how irrelevant people like Robot, with his deformity, are. At the same time, he is not without some regret. Seeing potential in The Immortal with his abilities so similar to a Viltrumite, Nolan openly wished he could've joined the Viltrum Empire. Also, he is sympathetic for his family's feelings, recognizing Mark's feelings for Atom Eve and sought to console Mark when he was forced to execute her.
History[]
Backstory[]
Born on the distant planet Viltrum into an imperialistic race of super-beings known as the Viltrumites, Nolan was indoctrinated with the Viltrumite creed of conquering as much of the galaxy as possible to assimilate other worlds, species, and civilizations into the Viltrumite Empire. Nolan joined the Viltrumite military forces as a young man and rapidly rose through their ranks through years of successful war and conquest. Eventually, the size of their ever-growing empire and their forces being spread thin prompted the Viltrumites to look for more efficient methods of galactic domination. To counter the raw man-power needed for a full-scale invasion into target planets, it was instead decided that the most trusted officers of the Viltrumite military would be assigned planets to weaken sufficiently in order to allow for a seamless takeover.
Nolan was assigned Earth and, as such, travelled there and created a new life on Earth, adopting the moniker Omni-Man and aligning himself with the original Guardians of the Globe and Global Defense Agency. Nolan also married a human woman named Debbie, and had his son, Mark. Unlike the main universe, while initially hesitant to the offer, Mark came to fully accept Nolan's point of view to assimilate Earth into the Viltrumite Empire, and together they learn Earth would not take lightly to obeying the empire, and destroyed most of earth's cities and guardians, leaving only a handful of heroes and military armies left to stop them.
At another point, Omni-Man and Mark had killed thousand of people during their attempts to swoon the earth over to their leisure.
Attacking The Resistances[]

Omni Man grabs the Immortal's fist.
One Night, Invincible was seen in the skies fought against The Immortal, telling him that he's trying to save lives. With Nolan's help managed the two finally ended the ageless warrior. Realizing he was merely distracting them, they discovered a underground resistance team in a city. They discovered their enemies location and their final interaction with the rebellion led by Robot and Eve, they kill Robot, but Mark still spared Eve, in his way by paralyzing her but still wanting to keep her and had "friends" to take care so that he could visit her in his spare times.

Nolan and Mark look at Atom Eve.
Invincible and Omni-Man were last seen killing the last of the resistance, however one of them did escape. The two presumably went to get food after this as Nolan was hungry after missing lunch due to a riot in Bangkok.
