Tragg

👑 Elite of the Empire

Conquest — The most brutal of the punishers. One of the oldest and most powerful warriors, a survivor of the Great Purge and the Corruption Virus. A living weapon sent only on the most difficult missions, he openly relishes violence. His body is covered in scars, and his right arm is replaced by a prosthetic. In their first battle, he brutally beat Mark and nearly killed Atom Eve, but was defeated with a series of headbutts. Mark later killed him during the Viltrumite War, strangling him during a critical battle.
Anissa is the most powerful female Viltrumite. She possesses incredible speed, even surpassing Nolan's. Unlike Conquest, she acts coldly and pragmatically, preferring to persuade first and destroy later. It was she who coerced Mark into a relationship, which led to the birth of her son, Marcus Murphy. She later acknowledged her mistake and became an ally.
Thragg is the absolute pinnacle of power. Genetically bred to be the perfect warrior and a former Grand Regent, he stands at the pinnacle of the Viltrumite hierarchy, and none of his race can match his might.

⚔️ Veterans and Standard Warriors

Thula, Vidor, and Lucan – Elite Hunters. They appear as a squad sent to punish Nolan. They easily destroyed an entire Thraxan civilization, demonstrating exemplary brutality even by Viltrumite standards.
Kregg, Kradd, and Elix are High Officers. They occupy the highest ranks among standard warriors and often act as advisors or field commanders.
