Charles Baker

Charles Baker is the main antagonist of the second half of seasons two and the whole of seasons three and four. He is a serial killer and rapist who was responsible for a series of rapes, kidnappings and killings and is on a life sentence, being one of the most dangerous prisoners. Despite outwardly appearing as a generous and kindhearted man, Charles is a very manipulative individual, often using this to command such loyalty from the inmates who make up his gang.

Charles becomes associated with fellow inmate Jeffrey Baxter and the two develop a friendship, as Jeffrey wants to befriend the new top dog after Diego Reyes' death to make the rest of his prison sentence easier. However, Jeffrey's association with Charles makes for an uneasy relationship with his cellmate Oscar Savage, and also Jeffrey becomes disgusted when he learns of Charles' true nature as he initially believed Charles was convicted for manufacturing meth, which apparently Charles showed remorse for because drugs lost him his family, while in reality Charles killed his own family. Charles also exhibited racist and sexist traits, and had a sexual interest towards the younger white males and forced them to be the "bitches" of his Neo-Nazi gang.

Personality
Charles Baker is an extremely malevolent and evil individual, being a complete psychopath with no regard for human life, and a ruthless sadist whom takes extreme pleasure in torturing others to achieve his goals. His dark and twisted personality makes Charles find humor or sport in the suffering and fear of his victims, and he himself is impossible to intimidate, due to his pathological fearlessness.

Charles is remarkably manipulative, able to attract women that he meets and commanding the respect and loyalty from his prison gang, in addition to being extremely intelligent and unpredictable. In addition, Charles is vain of his status as the inmate who runs the prison, evidenced by forcing his fellow prisoners to kneel in his presence and proudly targeting the young inmates and intimidating them into becoming his "bitches", showing dominance and control over them and promising to protect them in exchange for their undying loyalty. Charles also has a perchant for flamboyancy, lavishness and extravagance.

Despite his psychopathic malevolence, on some level, Charles had a strong respect for Jeffrey Baxter and considered him a friend in his own twisted way, developing an unhealthy obsession over him and considering their rivalry as fun, challenging and enjoyable to him once they become enemies.
