~ Omni-Man's villainous breakdown and his most infamous speech to Mark, from the TV series.

Omni-Man (real name Nolan), also known by his adopted name, Nolan Grayson, is the deuteragonist of the Invincible comic book series and the main antagonist of the first season of its 2021 animated adaptation. Omni-Man is the father of Invincible and Omni-Boy and a member of Viltrumite race, a humanoid species of extraterrestrial origin who possess superhuman strength, super speed, virtual immortality, and flight. As is customary for male Viltrumites, Omni-Man sports a large mustache.

He was tasked with conquering planets to spread the Viltrumite empire, and arrived on Earth to infiltrate their society to weaken a chance for them to defend themselves. Becoming a writer and superhero "Omni-Man", Nolan would have a son named Mark Grayson with a human woman named Debbie, who would become a superhero under the moniker "Invincible". Omni-Man would eventually reveal his plans and battled his son after killing all of the Guardians of the Globe, but would leave the planet due to his love for his son. Nolan would redeem himself and become the emperor of Viltrum after his true heritage was revealed.

In the animated adaptation, he is voiced by J.K. Simmons, who also played Vernon Schillinger in Oz, J. Jonah Jameson in Sam Raimi's Spider-Man trilogy and the Marvel Cinematic Universe, Terence Fletcher in Whiplash, and also voiced Skip in Aliens in the Attic, Cave Johnson in Portal 2, and Kai in DreamWork's Kung Fu Panda 3.


Early Life

Nolan was born on the planet Viltrum to Argall and an unnamed woman, and his heritage was hidden due to his father being killed by Thaedus. The Viltrumites would create a strong empire under Thragg, wanting to conquer planets and spread their influence across the galaxy. Reaching the appropriate age, Nolan decided to help the Viltrumites conquer planets, becoming a capable warrior that he would command his own unit. When Viltrum suffered from a virus, the empire decided to use their lifespans to infiltrate planets and societies to weaken their defense so they could counter-attack the Viltrumites.

Infiltrating Earth

Nolan took on the mission to infiltrate the planet Earth, and started his mission by befriending Cecil Stedman to learn about human culture. He took on the surname "Grayson" to appear more human, and Stedman set him up to be "Omni-Man", Earth's most powerful superhero.

During his mission, Nolan met and fell in love with an Earth woman named Debbie, whom he later married and had their son, Mark. Nolan would continue to fight against supervillains as "Omni-Man", and became an ally of the Guardians of the Globe, a superhero team. In addition, Nolan would falsely tell Debbie, Cecil, and the costume maker Art Rosenbaum why he was on Earth.

While raising Mark, Nolan told him that he would receive powers like him, but told him false stories of why he was on Earth as well.


When Mark gained his powers and became a superhero under the moniker "Invincible", Nolan would help his son fight against the Flaxans but was abducted by the creatures. He was stuck in their dimension for eight months, with the Flaxans neutralizing his powers and keeping him prisoner. Nolan's powers returned, however, and he revolted before escaping the dimension and returning his wife and son.

While working on his plans, he had Mark substitute for him to battle Allen the Alien and was kept occupied while his son later went to Upstate University. When his son returned home and overslept due to stopping many threats, Nolan put his plans into motion by going to the Guardians of the Globe's headquarters and killing all of them. Afterward, Nolan kept himself out of the spotlight to not become a suspect in Black Samson's investigation, and struggled with telling Mark his true origins.

Omni-Man kills the Immortal Again.jpg

When battling the Immortal again, Nolan killed him again in front of his son, and revealed his true Viltrumite origins and what his empire tasked him to do. He asked Mark to join him in conquering Earth, but his son refused and the two battled across locations until he was beaten. Though Nolan had Mark at his mercy, Omni-Man instead spared his son and fled the planet, crying while flying into space.

Realizing that he loved his son, Nolan decided to conquer another planet to lessen his crime for deserting the Viltrumite Empire and not going through with their plans. Arriving to Thraxa, Nolan learned that the Thraxans had a short life span and the oldest individual would rule the planet. Nolan became their ruler since he had lived for thousands of years, and sent a Thraxan to collect his son from Earth. While living on Thraxa, Nolan mated with a fellow Thraxan Andressa, and the two had a child named Oliver. The two reunite and reconcile, but Nolan refuses to return to Earth due to his actions and that he must stay on Thraxa.

He reveals to Mark that he had a son with a Thraxan, and that the child would be killed by the Viltrumites due to having a genetic flaw of having purple skin. Nolan and Mark would defend the planet from the Viltrumites, and the former is captured by Lucan and imprisoned alongside Allen the Alien. The two become friends and escape from confinement and the two decide to prepare themselves against the Viltrumites, as the empire is preparing to invade Earth.



I know this is a lot to take in at one time, but you're old enough to know the truth. And unfortunately... I'm not done yet. On top of all this... there's more. You see, you're getting older, son... things are going to start to change for you in a few years as you hit puberty. You're going to start to get acne. Your voice will start to crack and eventually change. You'll begin to grow hair in strange and new places. You're going to start looking at girls in a whole new light. There's a good chance that you're going to start to develop super powers. Super-Strength, Super-Speed, Flight... the whole bit. All the powers I have... Mark? Do you understand?
~ Nolan to his son, Mark.
The feeling is mutual.
~ Omni-Man killing the Immortal.
Son, stop. Listen to me. Do you have any idea what our life span is? The older we get the slower we age. We can't live among these frail things... your mother is little more than a pet. Viltrumite DNA is so pure and complete that you are nearly full-blooded. I could mate with nearly any alien being of comparable evolutionary development and produce a similar offspring. This means you will eventually become as strong as me. You could potentially be stronger... and you will live for thousands of years. Do you understand what this means? Everything you know and love will be gone before you look thirty years old. You do not belong here. Do you really want to watch your world die around you?
~ Omni-Man to Invincible.
They're not coming because they're no one to send. I am confident in this because I know how far away the Viltrumites are. My execution was postponed because they are called away—it was only recently that they were able to send back the two agents required by law for an execution. They had no else to spare. The reason is simple…there are less than fifty pure-blooded Viltrumites left alive in the whole universe. That's the secret...that's the thing they don't want anyone to know...that's why we can beat them.
~ Omni-Man to Allen the Alien.

TV Series

You don't seem to understand, Earth, isn't yours to conquer.
~ Omni-Man To A Flaxan Overlord and their army.
Where's Mark, William? You were suppose to drop him off an hour ago.
~ Omni-Man to William.
It's me, Mark. It's just me. This isn't how I wanted to do this, but I don't have a choice. It's time for you to know where I really come from: I am from Viltrum, but it's not the planet I've told you about: We have created a perfect civilization, but it took all of our strength, determination, and courage to get there. In order for our people to reach their full potential, we had to remove the weak from our society. It was a long and difficult process. When it was over, our population was cut in half but what emerged from the ashes was unstoppable. By the time I was born, Viltrum was already the greatest empire in our galaxy. We decided to make it the only empire in our galaxy. Once I was old enough, I joined the war effort. It was hard, but I believe in our cause. Some species resisted, of course, but no one could withstand us for long. Soon, our empire encompassed thousands of planets, but as territory grew, our forces were stretched thin, and our expansion stopped. We needed a better, more efficient way to conquer worlds. Our most trusted officers were each given a planet to weaken by themselves. I was one of those lucky few. I couldn't tell your mother why I was here. But that time's come to an end, and now, we need to get Earth ready to join the Viltrum Empire.
~ Nolan to Mark, revealing the truth about Viltrum and his purpose on Earth.
Do you have any idea how long we live? The older we get, the slower we age. Viltrumite DNA is so pure you're nearly full-blooded. You'll live for thousands of years. Do you understand what that means? Everyone you know and love will be gone before you even look 30. It's not something I want for you. This isn't your world. It's theirs. But we can help them. We can stop wars. Eliminate hunger. Give them medical technology centuries ahead of what they have now. We've already been doing it. If it wasn't for you and me, this planet would be in flames. All we have to do is welcome Earth in our empire.
~ Nolan to Mark, revealing their Viltrumite origins.
I do love your mother. But she's more like a... a pet to me.
~ Nolan to Mark on Debbie.
You don't know what you're saying. And I can't let you interfere.
~ Nolan to Mark.
So be it. Do you really think you can stop me?
~ Nolan preparing to fight Mark.
Look what they need to mimic a fraction of our power! It's right to pity them, Mark, but wrong to value them over your own kind.
~ Nolan to Mark when Cecil calls in an airstrike.
Instead, you saved him. So much effort... for what?
~ Nolan to Mark upon killing the pilot.
Now, or in 50 years when he's old, what difference does it make?
~ Nolan to Mark.
That was your fault. Your stubbornness against the inevitable killed those people. How many more need to die, Mark? It's up to you. And what we they doing with those fragile little lives anyway? Listen to what I'm saying. You know in your heart I'm right.
~ Nolan to Mark.
These people are meaningless. They're cavemen without us.
~ Nolan to Mark.
Sure. I was happy. For a time. But I'm loyal to Viltrum, not this pathetic excuse for a civilization.
~ Nolan to Mark.
You aren't not listening, Mark. My time here has been a speck in the span of my life, you don't know me. I will burn this planet down before I spend another minute living among these animals!
~ Nolan to Mark.
You're doing this for nothing. Being part of the empire will make Earth better than it was.
~ Nolan to Mark.
That's why we're here. To keep them from resisting. To show them how wrong they are, how pointless it is... That they can be part of something bigger. Or die.
~ Nolan to Mark.
You want to die for this planet? Fine. What's 17 more years? I can always start again... make another kid.
~ Nolan while punching Mark to near death.
WHY DID YOU MAKE ME DO THIS!? YOU'RE FIGHTING SO YOU CAN WATCH EVERYONE AROUND YOU DIE! THINK, MARK! You'll outlast every fragile, insignificant being on this planet! You'll live to see this world crumble to dust and BLOW AWAY! EVERYONE and EVERYTHING you know WILL BE GONE! WHAT WILL YOU HAVE AFTER FIVE HUNDRED YEARS!?
~ Nolan to Mark.


Supra-Man concept art.

  • Omni-Man's design, role to the Earth, initial personality and partial backstory are evidently influenced by Superman, though clear differences begin with Omni-Man's true original motive and much of his backstory.
    • The character was originally going to be named "Supra Man", but Image Comics made the writers changed the name due to it being too close the DC character, Superman.
  • Omni-Man bears a striking resemblance to J. Jonah Jameson from the Spider-Man comics. Interestingly, J.K. Simmons, who plays Omni-Man, played Jameson in Sam Raimi’s Spider-Man trilogy and in the Marvel Cinematic Universe.
