Oliver Grayson

Oliver's most noticeable feature is his purple skin, inherited from his Traxan genes. As a child, he had the same hairstyle as his older brother. As a teenager, he is short and thin, with two bangs framing the upper sides of his face. For clothing, he wears a white shirt with red sleeves and a red collar, and dark gray shorts. His superhero costume consists of a black eye mask, red tops, black bottoms, yellow gloves, and boots. His costume also features a yellow O logo, as well as a red I, making the costume somewhat similar to his father's outfit.

As a young child, Oliver represents the true nature of an innocent youth: curious, lively, and loving. As a teenager, he remains lively, but has developed into a stubborn and impulsive boy who does not fully understand the consequences of his actions. Although he is very friendly and outgoing by nature, in his quest to become a superhero, he has come to adopt a more logical rather than ethical perspective, as he does not recognize the horror of killing criminals, seeing it as a way to improve the world. This thinking comes from the fact that humanity tends to commit violence and destruction against each other so regularly. This has also led him to view non-superpowered humans as inferior to beings like himself and his brother. Although Oliver has a dark outlook on life, he cares for those around him and enjoys forming friendships whenever possible. He is especially attached to his family, especially his brother. He even respects his father so much that he bases his superhero costume and name on his father's. He is also open to evaluating other people's points of view and will stay away from deadly force if possible, as it worries his mother and brother.

Viltrumite-Thraxan Physiology: Despite being a hybrid, Oliver's Viltrumite genes are largely dominant, making him almost a pure Viltrumite. However, the incompatibility between his Viltrumite and Thraxan genes has resulted in certain characteristics emerging, namely his purple skin. His Thraxan background initially resulted in rapid aging, but it also caused his Viltrumite traits to emerge early on at a surprisingly young age, and he quickly adapted to them. Oliver has the best of both worlds: the formidable strength and abilities of the Viltrumites, and the advanced memory and learning ability of the Thraxans, all of which will only continue to increase as he ages. Slowed Aging: Oliver initially aged much faster than most species due to his Thraxan genes, physically becoming a 3-year-old when in reality he was 2 months old, and a pre-teen 3 months later. However, his Viltrumite genes gradually took over this. Since Viltrumites age steadily slower the longer they live, Oliver's own aging process began to level out by the time he reached puberty. After this, since the slowing rate of Viltrumite aging keeps them healthy, vital, fit, productive, and youthful in appearance, it also extends their longevity. In doing so, Oliver's probable lifespan is nearly identical to that of a pure Viltrumite, allowing him to exist for several millennia while remaining at the peak of his powers. Enhanced Mental Abilities: Oliver inherited his mother's Traxan traits, giving him an exceptional ability to learn. He absorbs and understands information quickly and completely. This also contributes to his rapid growth; he began talking and walking surprisingly early after birth. He can also withstand more blows than an adult.

Biological mother is a Traxan female, but Oliver doesn't know her. Mother is Debbie Grayson. Brother is Mark Grayson or Invincible.
