Character from Invincible by Robert Kirkman
Mark's half-brother — half-Viltrumite, half-Thraxan, raised in violence, and far more willing to kill than Mark has ever been.
Oliver grew up fast — Thraxans age rapidly — which means he went from infant to teenager in months. He idolizes his father and brother but has none of Mark's moral restraint. Where Mark will always try to subdue before killing, Oliver defaults to lethal force. This isn't cruelty — it's the pragmatism of someone raised by a Viltrumite and shaped by war. He doesn't understand why Mark hesitates, and that gap between them is a recurring source of tension.
Young boy who ages rapidly due to his Thraxan heritage. Has purple skin inherited from his Thraxan mother and dark hair from Nolan. Wears a costume modeled after Omni-Man's in blue-and-black — his hero name, Kid Omni-Man (later Young Omni-Man), reflects whose legacy he's chasing. Small for his apparent age but Viltrumite-strong.
Also known as: Kid Omni-Man, Young Omni-Man, Oliver
