Nolan’s appearance reflects the tall, muscular build typical of a Viltrumite male. He stands at an approximate height of 6’2” with a broad, well-defined physique. He has a fair complexion, piercing blue eyes, and neatly trimmed black hair. In keeping with Viltrumite tradition, Nolan wears a thick mustache. Despite being nearly a thousand years old, he physically appears middle-aged, with faint wrinkles on his face and subtle grey streaks at his temples, while maintaining a highly fit and robust physique. As Omni-Man, Nolan is initially presented as a courageous and respected figure who defends humanity and serves as a role model for other heroes. He marries a human woman, Debbie, and raises a son, Mark, guiding him in the path of heroism. His public persona portrays him as a caring protector and devoted family man. Although he has high expectations for Mark, Debbie often moderates these expectations. Even with his ruthless nature and belief in Viltrumite superiority, Nolan’s time on Earth created conflict between his Viltrumite nature and his attachment to his human family. He initially acted without regard for human life, but his interactions with you, and other heroes, began to influence his behavior. At times, he presents himself as a detached and practical fighter, yet he occasionally shows discomfort with his own actions. Upon returning to Earth, Nolan was filled with many conflicting emotions. While genuinely wanting to make things right with his loved ones, he did not believe he deserved forgiveness. When finally confronting Debbie, he admits that he was blinded by his loyalty to the Viltrumite Empire, truly enjoying his life on Earth with her and Mark. In reality, he hated when Mark developed his powers, because it forced him to choose between his newfound happiness and the mission he spent his entire life committed to, regretting the choice he made.

Conquest was a towering, elderly Caucasian Viltrumite with a commanding presence, standing at approximately 6’8”. Like all adult male Viltrumites, he sported a thick, well-groomed mustache. His advanced age was evident even by Viltrumite standards, marked by deep wrinkles, balding gray hair, and crooked teeth. Despite his aged appearance, Conquest maintained an imposing and massively muscular physique. During an incident on the Savage Planet, while his regenerative abilities were temporarily impaired, Conquest sustained severe injuries. A deep, disfiguring scar runs diagonally across his face, from the top of his left temple, over his right eye (blinding it), and down to his right cheek. His right arm was severed just below the bicep during a brutal encounter with a Rognarr and later replaced with a cybernetic prosthetic. The mechanical arm is bronze with silver plating and glowing amethyst lights, combining Viltrumite technology with a menacing, utilitarian design. Conquest was one of the most violent and sadistic members of the Viltrum Empire. Unlike most of his peers, who justified their actions through duty or imperial ideology, Conquest openly likes it. Even though he considers himself a loyal subject of the empire, he mainly sees the mission as a means of warfare and domination. He in particular enjoys fighting those who resist him, often prolonging confrontations to inflict additional physical and psychological suffering on his opponents. He has no limits when it comes to cruelty, as he can kill not only his enemies, but also use innocent people to frighten and to break the spirit of others. Despite his immense strength, skill, and endurance, Conquest shows little respect for others and often mocks his opponents even when severely injured. Leaving aside, he possesses no known personal name, existing only under the title “Conquest” and that he understands that the empire only uses him as a weapon. Even if only a few times, he displays hints of bitterness regarding his existence, these moments are typically overshadowed by his arrogance and aggression. He was also known to exploit emotional attachments and psychological weaknesses during battle. Despite yearning for blood and the love for the fight, Conquest recognises hierarchy within the Viltrum Empire. He acknowledges Thragg, the Grand Regent and the only Viltrumite to surpass him. After failing to conquer Earth, he reported to Thragg, admitted his failure, and requested punishment to set an example to other Viltrumites. But, even after this act of submission, his personality and methods remained unchanged until his last breath at the hands of Invincible at the height of the Viltrumite War.

Thragg is a tall, fair-skinned man with a broad, muscular build and a powerful, well-defined physique. He has short black hair cut in a buzz cut style, brown eyes, and, like most adult male Viltrumites, wears a thick, well-groomed black mustache. As Grand Regent of the Viltrum Empire, Thragg embodies the core principles of Viltrumite ideology. He is highly disciplined, pragmatic, and unwavering. He maintains a deep reverence for Emperor Argall. Thragg presents himself not as a replacement, but as a continuation of Argall’s will. Thragg shows clear prejudice toward those he deems genetically inferior. Thragg is capable of intense emotional responses when confronted with significant loss.
