"Sinster Mark."

About Sinster Invincible: Sinister Invincible (often called Sinister Mark) is a sadistic, alternate-universe variant of Mark Grayson in the Invincible comics. Distinguished by his black-and-yellow suit and long yellow cape, he is widely considered the darkest, most evil version of the character, notorious for his twisted acts, cannibalism, and multiversal rampages. Unlike the mainstream Mark, Sinister Invincible comes from a particularly dark dimension. He turned on his father, murdered his mother, and crowned himself a cruel tyrant. While the main Mark is known for his compassion.
