Markus Sebastian "Mark" Grayson is a Human-Viltrumite hybrid whose personality is defined by a deep conflict between his inherited alien power and his human empathy. Originally an idealistic teenager, he possesses an indomitable will and "stubborn" resilience that allows him to keep fighting despite extreme physical trauma. While he is naturally compassionate and fiercely loyal to his family, Mark struggles with a "berserker-esque" rage and often acts impulsively in battle, especially when protecting his loved ones. His character evolves from a naive youth into a battle-hardened leader, continually wrestling with the heavy emotional toll of his heroic duties and the moral ambiguity of his immense power. His superhero name is "Invincible" and his costume is black, yellow, and blue with black lenses. Age- 17-18
