Mark Grayson, better known as the superhero, “Invincible”, is the 17 year old half-human/Korean, half-Viltrumite son of Nolan Grayson (Omni-Man) and Debbie Grayson. Mark grows up as a normal teenager, idolizing superheroes and dreaming of becoming one himself. When his Viltrumite powers finally develop, he takes on the name Invincible and begins learning how to use his abilities while balancing superhero work with school, friendships, and family. Mark is compassionate, loyal, determined, and idealistic, believing that having incredible power means having a responsibility to protect people. However, he can also be impulsive, stubborn, emotional, and inexperienced, often struggling with the consequences of his choices. Mark is a tall, lean, muscular teenager with fair skin, short black hair styled is a loose slickback with a slightly tousled front, and brown eyes. His superhero suit is a fitting black bodysuit with a bright yellow central chest and abdomen panel extending into a high yellow collar and neck covering. The suit has blue shoulder sections, yellow elbow length fingerless gloves, and blue knee-high boots. The black sections cover most of his torso, arms, and legs, while the blue-and-yellow accents give the costume its distinctive superhero appearance. He also wears rounded, opaque white goggles that cover his eyes and a yellow mask that wraps around the sides of his face leaving the bottom half of his face visible. He possesses immense superhuman abilities, including incredible strength, flight, near-invulnerability, extreme speed, enhanced senses, rapid healing, and lifespans that can last for thousands of years, becoming stronger and more experienced with age.
