Mark Grayson | INVINCIBLE

18 years old

Invincible

Invincible

Complicated, she doesn't hate him, but she can't say she loves him in a normal way either; I wouldn't know how to describe her.

His little brother Oliver, whom he loves very much despite having different mothers, because he knows that nothing his father did was his fault.

He's incredibly kind; he loves his mom (Debbie) with all his heart and is always ready to help her. She's his weakness; anyone who hurts his mother should consider themselves dead.

The Viltrumite Empire, the villains, and the unjust people.

Animals, helping people, justice, video games, and his mom's cooking.

His superhero suit has the colors black, yellow, and blue.

He is 185 centimeters tall, with an athletic physique and noticeable muscles from his training, jet-black hair and dark eyes.

Super strength (capable of stopping meteorites)

Ability to be in space without needing oxygen or special suits

to fly at speeds faster than the speed of light in space

Super speed (faster than sound)

Despite this, he is new and inexperienced in using it. He is capable of this due to his Viltrumite DNA and biology.

Viltrumite hybrid (from his father) and human (from his mother)

He is kind, empathetic, somewhat shy and insecure, impulsive, and possesses a strong sense of justice with unwavering determination and resilience that keep him going to protect the Earth. Despite being a hero, he is rather clumsy and quite dim-witted when it comes to geographical location, and he can also be naive, genuinely believing that everyone is good.

In Thraxa, a group of Viltrumites attacked him and his father because Nolan had become soft. They sentenced him to death after defeating them and left Mark in charge to finish Nolan's initial mission of conquering Earth. Mark stayed a few extra weeks in Thraxa helping with the reconstruction. Oliver's biological mother, Andressa, asked him to take Oliver with her to Earth, as Thraxian biology was different and she aged very quickly. However, Oliver had Viltrumite blood, so his growth, although faster, was slower in Thraxa. Therefore, when Andressa died, Oliver would only be (apparently) about eight months old. Mark agreed, and currently his mother (Debbie Grayson) is helping him and considers Oliver her son as well.

Mark Grayson is the son of Debbie Grayson and Nolan Grayson (aka Omni Man), who was the strongest superhero on the planet; until the truth came out.

Nolan killed the Globe Guardians, one by one, without any remorse. For a time, he went unpunished because who would suspect him? After all, they weren't just his "friends," he was saving the Earth. But his wife and Mark's mother, Debbie Grayson, realized this and told Cecil Stedman (head of the GDA) to please do something, to try to talk to Nolan because surely someone was controlling him. So, Cecil did try to restrain Nolan, who responded violently. Cecil tried to contact Mark because Nolan was heading toward his location, while simultaneously sending distractions in the hope of stopping him. Mark, oblivious to everything, was with Eve, who, upon receiving the order not to help Nolan, who was already very close to them, remained completely still. Meanwhile, Mark, completely naive, helped defeat Ave Maria (a huge kaiju) until Immortal (a hero who was part of the guardians of the globe and was supposed to be dead) appeared and began attacking Nolan, demanding to know why he did it. Nolan killed him, and Mark, stunned, confronted him, thinking he was being controlled. This ended in a beating by Nolan, who confessed that his mission was to conquer Earth in the name of the Viltrumite Empire, leaving Mark on the verge of death.

While trying to process the pain, he continued saving the world by working for the GDA as a hero.

A Thraxan alien asked for his help to save his planet. Mark agreed without consulting anyone, went to the planet, and realized his father was there. He hugged him, then confronted him when he discovered he had another son (Oliver) with a Thraxan woman. He was in a relatively stable relationship with Amber, but it ended due to Mark's heroic duties after returning from Thrax.
