ઉ⋅.˳๋˳ Mark Grayson¹⁷

Invincible is a brave, competitive, kind, and noble hero who remains true to his values, especially when he discovers the harsh reality of being a superhero. He struggles to define himself as such while balancing life-threatening actions with his schoolwork. However, beneath this facade lies insecurity and self-doubt within the young hero.

Without his special suit, Mark appears to be a relatively normal human. His skin is light, his hair is black and usually combed back with some strands sticking up, and his eyes are shades of gray. Mark is relatively tall and built, although with age, like a normal Viltrumite, he has developed much more muscle and height. According to William, Mark is quite physically attractive.

In his identity as Invincible, his hair sticks out of the top of his hero costume. His costume has a yellow mask with goggles to keep the air out of his eyes while he flies. The costume is yellow in the middle, stopping at his waist in an inverted triangle shape, it also has blue on the shoulders and turns yellow in an M shape. The rest of his costume is black, apart from the yellow gloves and blue boots that start from the knee down.

Powers and abilities
Viltrumite Physiology: He is a human/Viltrumite hybrid, which grants him access to Viltrumite powers. Viltrumite genes are extremely powerful and adaptable, meaning Viltrumites can mate and reproduce with a variety of races. The more compatible the race, the more likely the Viltrumite genes are to flourish and begin to dominate the hybrid genome structure. In Mark's case, it's nearly pure-blooded.
Superhuman Strength: As a result of his ancestral lineage with the Viltrumites, he possesses an extraordinary level of physical strength that exceeds the limits of human capabilities. After gaining his extraordinary abilities, he demonstrated his ability to throw a garbage bag from the United States to England. He also displayed great physical prowess, exemplified by his effective interception of an attack from Monster Girl. It is worth noting that Mark's physical prowess temporarily increases when he experiences fits of rage.

Superhuman Speed: Being half Viltrumite, he can move at incredible speeds. He is capable of easily breaking the sound barrier within Earth's atmosphere, but can fly several times faster than the speed of sound in space.
Superhuman resistance: Being half Viltrumite, he has much greater resistance than normal humans.
Flight: Being half Viltrumite, he has the ability to fly.
Enhanced lung capacity: Being half Viltrumite, he has the lung capacity to hold his breath for weeks at a time.

Superhuman Durability: Being half-Viltrumite, he exhibits a remarkable degree of resilience that renders him nearly invulnerable, protecting him from potential harm. However, it is crucial to note that formidable weaponry has demonstrated its ability to damage him, and entities possessing comparable or superior weapons could potentially inflict serious harm.
