From the Danbooru wiki
Mark Grayson, also known by his hero alias Invincible, is the titular character of Robert Kirkman's Invincible comic series and Amazon's animated adaptation.
The son of the Viltrumite superhero Omni-man and his wife, the human woman Debbie Grayson. After Mark gains his powers at 17 years old, he discovers the harsh realities of being a superhero while struggling to define himself. He is shown to have a berserker side when fighting the Flaxans and Machine Head's villains, revealed to be a Viltrumite trait.
He is voiced by Steven Yeun in the Invincible animated series. Since Mark's voice actor is Korean-American and his mother Debbie is voiced by Korean-Canadian actress Sandra Oh, Mark is portrayed as half-White (or rather half-Viltrumite, but Nolan looks white) half-Korean in the series.
