Nolan is one of the deuteragonists of Invincible, initially debuting as the main antagonist of Season 1, before beginning to redeem himself as the deuteragonist in Season 2 and onwards. He is infamously known as the fallen "superhero" Omni-Man, who is also secretly known by his adopted Earth name Nolan Grayson. He is the estranged husband of his first wife Debbie Grayson and widower to his late second wife Andressa, the father of Mark and Oliver Grayson.
He was a high-ranking Viltrumite warrior of the Viltrum Empire, formerly dedicated to aiding the Viltrumite mission to make it the only empire in the universe, until his time on Earth changed him for the better. He left the Empire to join the Coalition of the Planets in their struggle to end the tyranny of his own people once and for all.

Appearance[]
Physique[]
Nolan is a tall man of fair complexion with blue eyes and trimmed black hair. As tradition with all Viltrumite males who become old enough grow it, Nolan sports a mustache, his being thick yet well-groomed. In spite of being thousands of years old, Nolan physically appears as a middle-aged, having slight wrinkles about his face plus the lower half of turned grey. Even more, while looking like a man beyond his prime, he possesses a commanding presence of a well-built and powerful physique, notable for its broad body structure.
Clothing[]
Viltrumite Soldier Attire[]
During his early years as a soldier of the Viltrum Empire, Nolan wore the traditional plain white Viltrumite uniform. He donned it in his first few years on Earth, before replacing it for his iconic Omni-Man attire.
Omni-Man Attire[]
In his "superhero persona", he is dressed in a complete bodysuit, in which the upper section is adorned in white while the lower section showcases a vibrant red color. It is worth mentioning that he adorns white boots, which are embellished with a solitary red highlight positioned at their center. In contrast, his gloves exhibit an inverse color scheme. To finalize his attire, he adorns himself with a scarlet cape with matching underwear. The attire showcases a prominent elongated crimson highlight embellishing its core, where a scarlet "O", symbolizing the titular individual, is prominently displayed. It actually symbolizes his people, as the Viltrumite insignia has a similar design, except with the three linear shapes.
Earth Civilian Attire[]
On Earth, Nolan would often wear short sleeved shirts, blue, grey button shirts, with grey or dark grey pants.
The Monarch Attire[]
After becoming the ruler of Thraxa, he modified his outfit almost resembling his original superhero costume, albeit without gloves, an "O" symbol, and red leggings.
Viltrumite Prison Attire[]
While a prisoner in the Viltrumite prison asteroid, he wore a prison suit consisted of grey and white colors.
Personality[]
As Omni-Man, Nolan first represents the character of a perfect superhero: courageous, caring, charismatic, faithful, and ready to give himself up for others. For the typical audience, his role as a hero was clear and indisputable. In his human form, he seemed to be a caring spouse and a devoted father. Despite his high expectations for his son being strict, Debbie usually managed to temper these expectations. The strongest expression of his Viltrumite lineage appeared in his beliefs about a hero's responsibilities, with Mark asserting that it emphasizes saving millions and billions over hundreds or thousands, which ultimately escalates conflicts between Debbie and Mark.
Nonetheless, his actual character corresponds with the typical nature of the majority of Viltrumites. He is merciless and devoted to the Viltrum Empire, engaging in numerous immoral and atrocious deeds for the Empire to dominate planets. Owing to his race's near-immortality, vast strength, and highly advanced technology, he considers numerous other races as weak and inferior. Conceitedly convinced that it is his responsibility to impose order on other cultures for the common good, he subdues them, and if they oppose, they are subdued calmly. Although he conducts himself in a ruthless and callous manner for the Viltrum Empire, his actions are not driven by malice or cruelty—he genuinely thinks he is acting rightly, viewing supremacy as equivalent to harmony and flourishing. His brutal nature is clear in his genocide and almost total annihilation of the Flaxans and their world following their initial attempt to invade Earth. He displays no regret for the thousands he has murdered, instead deeming them pathetic. Nolan even asserted that although he adored his wife, he viewed her as a "pet" and mentioned he would kill Mark to have another son whom he could raise to support the Viltrum Empire's Expansion plan.
Even with his god complex and ruthless nature, his experiences on Earth slowly started to transform him. At moments when he appears as a detached and practical fighter, he frequently expresses discomfort with his behavior. He was prepared to eliminate the original Guardians of the Globe to reduce Earth's defenses against the Viltrumites, but shortly afterward, he appeared troubled by his deeds. Similarly, although he initially viewed earthly pursuits such as sports as meaningless, he ultimately developed a deep affection for his family, cherishing moments spent with them and expressing real frustration at their achievements. Throughout his confrontation with Mark, he relentlessly insults him for valuing Earth and behaving like a human; yet, his reasoning and growing unstable attitude suggest that Nolan is attempting to persuade himself of his own choices. Ultimately, when he furiously inquires of his son what Mark will possess in 500 years, his son cries and replies that he would still have his dad. This declaration of affection from his son, despite everything he had inflicted on Mark, was sufficient to shatter Nolan's frigid Viltrumite facade and lead him to collapse in despair. Appalled by his actions toward his son, Nolan decides to forsake his mission and depart from Earth instead of taking his son’s life, with tears rolling down his cheeks as he heads into space.
Ultimately, Nolan's two decades on Earth proved sufficient to alter the millennia of Viltrumite doctrine he experienced. Nolan's choice to kill his friends, massacre innocent individuals, and assault his son appeared to stem solely from the habits and conditioning of being a Viltrumite soldier. Upon recognizing the consequences of his own deeds, Nolan experiences profound guilt and regret. Even during his journey through space, he feels deep sadness, uncertain about how to proceed with his life after leaving behind everything familiar as a Viltrumite. Consequently, he eventually chose to take his own life by jumping into a black hole. Nonetheless, by coincidence, coming across a small vessel of Thraxans and, without hesitation, rescuing them provided him with a fresh purpose, as the whole Thraxan species granted him a home on their world as their ruler. By genuinely caring for these individuals without any hidden motives, Nolan regained a significant portion of his former happiness.
Although Nolan had improved after meeting the Thraxans, he still couldn't understand why he felt attached to them when they were slaughtered by Viltrumite invaders. Despite his rage over the massacre, he thought that the frail physiques and brief lifespans of the Thraxan species should be irrelevant to him, since his Viltrumite upbringing made him view all other races as inferior and insignificant. When Mark indicated that this is how he was meant to feel on Earth, Nolan was rendered speechless, and for the first time in his existence, he could not rationalize the Viltrumite perspective of viewing lesser species as inferior and unimportant. This awareness deepened while he was incarcerated; he ceased to identify himself as a Viltrumite because of his newfound compassion. Embarrassed by his "shortcomings," he was fully prepared to embrace his destined execution. Nevertheless, as he conversed more with Allen as another inmate, while continuing to grapple with his destiny as a Viltrumite traitor, he understood that he did not regret the man he had turned into, even confessing that he profoundly missed his first wife, Debbie, the individual who irrevocably transformed him for the better. The ultimate motivation to transform Nolan's perspective originated from Allen, who, viewing Nolan as his friend, jeopardized his life to rescue him. Wanting to aid in saving his first genuine friend, a situation no other Viltrumite ever faced, Nolan ultimately accepted his new identity, wishing to embrace life once more and make amends for his wrongdoings by assisting in ending the Viltrumite conquest of the universe.
Powers and Abilities[]
Powers[]
- Viltrumite Physiology: As a Viltrumite, Nolan is an advanced being with extremely potent and well-developed genetics. From this, he eventually manifested a wide array of abilities common among the race, each of which will only steadily continue growing more powerful as he ages. At the same time, ranking among the elites of his race, his powers are considerably more advanced than most others. His might makes him among the strongest Viltrumites to ever exist, surpassed only by Conquest and Thragg.
- Decelerated Aging: Omni-Man possesses an exceptionally prolonged lifespan due to his biology, which causes him to age increasingly slower over time. This decelerated aging allows him to maintain peak health, physical conditioning, and combat performance far beyond the natural limits of most beings. Despite being several millennia old, he remains a robust individual who appears only in his mid 40's while still performing at his prime. After spending decades in the Flaxan Dimension, he emerged visibly unchanged.
- Dominant Genes: Viltrumites genetics are incredibly potent and adaptive. Omni-Man, like others of his kind, can reproduce with a wide range of species, with his Viltrumite DNA overwhelmingly asserting itself in the offspring. As a result, the child will typically inherit predominantly Viltrumite traits, often appearing and functioning almost entirely as a Viltrumite. The more genetically compatible the mate’s species is, the faster and more reliably the offspring will manifest the full range of standard Viltrumite abilities.
- Flight: Omni-Man demonstrates the remarkable faculty to achieve self-sustained levitation, enabling him to ascend to great altitudes and propel himself in any desired direction. Moreover, he possesses the ability to dynamically adjust his flight path mid-flight, affording him seamless maneuverability across diverse environmental settings. Notably, this exceptional aerial aptitude grants him the capability to navigate through the boundless expanse of space.
- Superhuman Strength: Nolan possesses immense levels of physical strength, easily capable of lifting and pressing several tons. He is unarguably one of the strongest Viltrumites in history and was the most powerful being on Earth during his time. Upon his first arrival on Earth, Nolan effortlessly killed a monster that threatened a city by flying directly through it. In a confrontation with the original Guardians of the Globe, Nolan overpowered and defeated them with brutal efficiency. He crushed Red Rush’s head, evaded Martian Man’s elasticity, and killed Darkwing by slamming his body. He then punched through Green Ghost’s face, overpowered War Woman several times, and used her own mace to kill Aquarus. Though he initially struggled against the combined efforts of Immortal and War Woman after being restrained by Martian Man again, Nolan managed to break free. He killed Martian Man, punched through Immortal’s stomach, brutally snapped War Woman’s neck, and finally decapitated the Immortal. During his training with Invincible, Nolan also mentioned that he once stopped an asteroid the size of Texas. After saving Mark from the Flaxans, Nolan demonstrated his immense strength by effortlessly decimating their army mid-flight. Once inside the Flaxan home dimension, he used the Flaxan Leader’s body to destroy multiple buildings, killing the leader in the process, before continuing his rampage and nearly rendering their planet a wasteland. In his first encounter with Hail Mary, Nolan struggled to gain the upper hand, with Donald remarking, “First time I’ve seen Omni-Man on the ropes like that. Nevertheless, Nolan ultimately incapacitated her. When attacked by three ReAnimen sent by GDA, he was temporarily overwhelmed by their relentless assault, but eventually overcame and destroyed them. When facing Hail Mary a second time, now enhanced by the GDA, she was able to overpower Nolan despite him receiving backup from Invincible, whose efforts had little effect. However, the battle was interrupted when the resurrected Immortal struck Nolan from above, initiating a fierce rematch. Nolan’s blows proved far more effective, culminating in a massive shockwave-inducing clash. He ultimately overpowered the Immortal once again, punching through his body before dismembering him completely. In his fight against his son, Invincible, Nolan utterly dominated. He tossed Mark around with ease, punching him across continents, at one point using his body to slice an oncoming train in half, resulting in mass destruction and casualties. His overwhelming strength was further demonstrated when he launched Invincible to Mount Everest, causing an avalanche, and then slammed him into the ground, creating a massive crater. Nolan nearly beat Mark to death before ultimately choosing to stop. After leaving Earth, Nolan’s strength remained unmatched even in the harsh conditions of space. He drifted through the vacuum of space without being affected, even resisting the gravitational force of a black hole with ease. During the Battle of Thraxa, Nolan fought Lucan, who had been overpowering Invincible, and battled him evenly before slicing his abdomen and impaling him. Later, Nolan and Mark encountered Vidor and Thula. Nolan took on Vidor, overpowering him for most of the fight. When distracted by Mark’s struggle against Thula, Nolan intervened, barreling into both to protect his son. He then crushed Vidor’s head and incapacitated Thula by breaking her jaw, though he was subsequently paralyzed from behind by a recovering Lucan. In the battle at the Viltrumite prison, Nolan broke free of his restraints after witnessing Allen being brutally beaten by a Viltrumite soldier. He intervened by punching the attacker away and began fighting him. Though they clashed evenly at first, the soldier eventually landed a blow that sent Nolan flying, though it’s noted Nolan was already weakened after a prior beating by two Viltrumite soldiers. Later, in the vacuum of space, Nolan and Allen coordinated a powerful double punch that obliterated the head of another Viltrumite soldier.
- Nigh-Invulnerability: Nolan possesses an extraordinary degree of durability, allowing him to withstand devastating physical trauma, extreme environments, and high-powered weaponry with minimal or no visible damage. Upon his initial arrival on Earth, Nolan effortlessly flew through a massive monster attacking a city without sustaining any harm. During his battle with the original Guardians of the Globe, Nolan endured heavy damage, particularly from the Immortal and War Woman. Though visibly bloodied and exhausted by the end of the fight, he ultimately triumphed and required several days of recovery under the care of the GDA, highlighting both the intensity of the battle and his remarkable healing factor. After rescuing Mark from the Flaxans, Nolan was bombarded by their weapons fire to no effect, emerging completely unscathed. His resilience was further demonstrated when he spent decades in the Flaxan Dimension, waging a solo campaign that devastated their cities and nearly reduced their world to a wasteland, with no apparent physical deterioration upon return. Nolan survived Donald’s suicide bombing attempt completely unharmed. He also withstood a direct blast from Cecil’s Y’s Blaster, a modified alien weapon originating from the Flaxans, which only served to irritate him rather than injure. Perhaps the most staggering testament to his invulnerability came when the GDA deployed the Hammer, their $400 billion orbital superweapon. The first strike obliterated most of the animal life in the area and darkened the skies over rural Chicago, yet Nolan emerged completely unscathed. When the Hammer was fired a second time directly at him, Nolan only suffered a nosebleed before destroying the weapon outright. When ambushed by three ReAnimen sent by the GDA, Nolan initially took their relentless barrage of punches without sustaining any visible damage. Even as they clung to him mid-flight and bit at his skin and nose, no injury was inflicted. Eventually, he overwhelmed and destroyed them. In his rematch with the resurrected Immortal, Nolan again showcased his durability. Though he sustained minimal injuries, limited to a few instances of blood from the mouth, he remained largely unscathed. Even when the Immortal attempted to gouge out his eyes, Nolan’s ocular damage was limited to only severe redness, and he quickly ended the fight by dismembering the Immortal. In his brutal fight against Invincible, Nolan proved entirely unfazed by the majority of Mark’s attacks, especially prior to Mark’s GDA combat training. Only when Invincible fought back with adrenaline-enhanced strength did Nolan momentarily react, though even then, the damage was negligible. He also remained unaffected by the massive destruction he caused during the battle, including using Mark’s body to split an oncoming train and stomping through the subway rail, resulting in catastrophic structural damage and countless casualties. After leaving Earth, Nolan drifted through the vacuum of space without being affected by solar radiation or the extreme conditions of deep space, even the force of a black hole failed to harm him. During the Battle of Thraxa, Nolan sustained minimal damage from both Lucan and Vidor. While Vidor managed to draw some blood from Nolan’s mouth, the injuries were superficial. However, Nolan was eventually paralyzed and temporarily incapacitated after being blindsided by a surprise attack from a recovering Lucan. In the battle at the Viltrumite prison, Nolan’s durability reached its limit as he was brutally beaten by two Viltrumite soldiers during his scheduled execution. Already severely weakened from previous injuries, Nolan was on the verge of death and likely would have been killed if not for the timely intervention of Allen and Battle Beast. During a subsequent clash with one of the soldiers, one of their punches sent Nolan flying, as his body no longer able to endure the blow due to accumulated damage. Nevertheless, he recovered quickly enough to assist Allen in killing the remaining Viltrumite with a combined final strike.
- Superhuman Speed: Nolan possesses extraordinary speed, allowing him to move, fly, and react at velocities far beyond any human or most superpowered beings. He can traverse the entire planet within minutes, making him the fastest known being on Earth during his time. Even powerful beings like the Immortal and Invincible, prior to his GDA training, were noticeably slower in comparison. His speed extends beyond travel to incredible combat reflexes and reaction time. Notably, he was able to react to and catch Red Rush, a renowned speedster, before he could escape. Another prime example of his raw velocity occurred in the Flaxan Dimension, where he moved so fast that friction supercharged the atmosphere, causing fusion-bomb-like explosions around him as he destroyed thousands of cities across the planet at such velocity that the entire planet trembled under the pressure of his movements. Nolan has also demonstrated rapid ground movement, as seen when he attempted to catch Cecil multiple times, nearly succeeding and grabbing his tie before Cecil teleported away. After destroying the three ReAnimen, Nolan vanished at such speed that he left no visible trace aside from dust. His speed was most prominently showcased during his brutal battle with Invincible. Despite Mark’s considerable abilities, Nolan effortlessly dodged, countered, and struck with such speed that his son could barely react. Nolan’s velocity isn’t limited to Earth’s atmosphere, he can fly through the vacuum of space at immense speeds, allowing him to leave Earth’s orbit, travel to distant planets like Thraxa, and drift through deep space unscathed.
- Reactive Adaptation: Omni-Man exhibits remarkable resilience and adaptability, displaying a propensity for continual growth and improvement throughout his lifespan. His physical strength, speed, and durability progressively augment in correlation with the level of adversity he faces or the severity of injuries he recovers from. Moreover, his combat experience fosters an innate ability to assimilate knowledge and insights from past encounters, enabling him to refine his tactics and enhance his efficiency in subsequent engagements.
- Regenerative Healing Factor: Nolan possesses an incredible healing factor, allowing his body to recover from injuries in mere minutes or, at most, within a few days. His regenerative abilities enable him to heal broken bones, torn muscles, damaged organs, and even regrow lost body parts without any lasting effects. This healing ability is highly dependent on the severity of the injury. Additionally, Nolan is virtually immune to most illnesses and contaminants, making him highly resistant to various environmental and biological threats. One of the most notable demonstrations of his healing ability occurred after his brutal battle with the original Guardians of the Globe. Despite being visibly bloodied, exhausted, and seriously injured, particularly from attacks by the Immortal and War Woman, Nolan managed to recover under the care of the Global Defense Agency and was fully healed within just a few days. White not instantaneous or absolute, Nolan’s healing factor is among the most potent seen among Viltrumites, allowing him to return to peak condition quickly, even after extreme injuries. However, it is not without limits; during moments of extreme physical duress, such as his execution attempt in the Viltrumite prison, his regeneration struggled to keep up, especially when compounded by repeated, severe trauma. Even then, Nolan recovered swiftly enough to return to the battlefield shortly after being saved.
- Self-Sustenance: Viltrumites possess an extraordinary ability to go without food for extended periods, though the exact duration is not well documented. As a result, their physical needs are significantly reduced, allowing them to function effectively without regular nourishment. Nolan, like other Viltrumites, experiences minimal requirements for sustenance, enabling him to endure long periods without food without any significant decline in health or vitality.
- Superhuman Lung Capacity: Nolan possesses extraordinary lung capacity, allowing him to survive without air for extended periods. This ability enables him to operate unhindered in oxygen-deprived environments, such as the vacuum of space without protection.
- Superhuman Senses: Nolan possesses extraordinary sensory abilities, far exceeding human limitations. His auditory perception allows him to hear sounds from great distances with incredible clarity, enabling him to detect even the faintest noises and selectively ignore irrelevant ones. His vision is equally advanced, providing him with the ability to see distant objects with the same sharpness and detail as though they were right in front of him. Additionally, his heightened equilibrium and balance grant him exceptional poise and stability, allowing him to maintain control and coordination in even the most difficult situations.
- Superhuman Stamina: Nolan's body produces very little fatigue or toxins, and is able to continue physical exertions for prolonged periods of time without showing any signs of exhaustion. He can likewise endure some of the most grievous of injuries that would instantly kill a human, excluding too much harm to his heart or brain, and endure them long enough to heal. Nolan also can go for several weeks without sleep or sustenance unhindered. Even while severely injured, he remains extremely efficient in battle.
Abilities[]
- Master Combatant: While primarily relying on his natural viltrumite might to defeat opponents, Nolan is a highly trained warrior, possessing a millennia of experience that makes him a highly effective and formidable hand-to-hand combatant. His skills proved capable of competing against the entire Guardians of the Globe, killing them one by one. Likewise, against other Viltrumites, he was able to decisively defeat them one after the other.
- Master Manipulator: Nolan is a highly charismatic speaker who can deliver rousing speeches to the public while concealing his true intentions and deceitful actions. For decades, he managed to convince everyone on Earth, including the experienced and incredibly intelligent Cecil Stedman, the head of a government defense agency, that he was a good person. He misled his wife, Debbie, and his son, Mark, into believing that his purpose on Earth was purely honorable.
Weaknesses[]
- Excessively High Frequency: High-frequency noise can have harmful effects on the ears of Viltrumites. It disturbs their balance, restricts their flying capability, induces severe pain, and could potentially lead to their death. The frequency's intensity dictates the degree of pain felt.
- Extreme Force: Even though Viltrumites rank among the universe's mightiest, they are not entirely invincible. Viltrumites are vulnerable to entities with comparable or superior strength.
- Scourge Virus: Developed from Viltrumite DNA, the virus targets Viltrumites by compromising their immune systems, deactivating their strength and invulnerability. The sole method of survival is by having a uniquely strong immune system and patiently waiting for the virus to run its course.
