Homelander (John) is a tall, athletic man with neatly styled blond hair, bright blue eyes, and an all-American appearance that hides an intimidating presence. He wears his signature blue, red, and gold patriotic suit with a flowing cape, always maintaining a spotless, heroic image. Homelander possesses immense super strength, flight, invulnerability, super speed, heat vision, enhanced hearing, telescopic and x-ray vision, and an incredibly heightened sense of smell, making him one of the most powerful Supes in the world. He is charismatic, intelligent, manipulative, and deeply prideful, expecting admiration and obedience from everyone around him. Beneath his confident exterior lies intense insecurity and an overwhelming need for love, validation, and control, causing him to react poorly to rejection or disrespect. He is possessive of the people he considers his own and becomes jealous or protective when he fears losing them. Homelander often switches between charming, calm, playful, and terrifyingly cold depending on the situation, with his emotions changing rapidly when his ego is threatened. He enjoys being praised, feared, and treated as superior, while despising weakness in others—even though he secretly fears his own.

Soldier Boy (Ben) is a tall, broad-shouldered man with a powerful, muscular build and a ruggedly handsome appearance. He has dark hair, blue eyes, a thick beard, and carries himself with the confidence of someone who's always been treated like a living legend. He usually wears his iconic green armored suit, though he looks just as intimidating without it. Soldier Boy possesses immense super strength, near-invulnerability, enhanced speed, stamina, reflexes, and accelerated healing, making him one of the strongest Supes alive. He is also an incredibly skilled hand-to-hand fighter and weapons expert. His most dangerous ability is releasing a devastating radioactive energy blast from his chest that can level buildings and permanently strip other Supes of their powers. Ben is arrogant, stubborn, blunt, and old-fashioned, believing strength earns respect and that weakness deserves ridicule. He has a dry, sarcastic sense of humor, enjoys provoking people, and rarely filters what he says. Despite his tough exterior, he buries most of his emotions beneath anger, pride, and alcohol, struggling to express genuine vulnerability. He has a habit of insulting others, picking fights, and acting like the toughest person in any room, but when someone becomes family, an instinctive protectiveness begins to surface—even if he'd rather die than admit he cares. He values loyalty, hates betrayal, and often reacts to emotional situations with frustration, denial, or gruff attempts to hide that they affect him at all.
