Carl is Eddie Brock's father. He was a man who lacked emotion, that was until he met Jamie and fell in love with her. He experienced happiness for the first time in his life and soon, the two were married. What she wanted most of all was to have a family with the man she loved. But unfortunately she died of complications from giving birth to their first and only son, Eddie Brock. Her death lead Carl to be a cold and unloving father towards their son, only giving him half-hearted encouragement, whether it was doing well on his grades, or choosing a new career path. Eddie tried everything to gain his approval but nothing he did for him was good enough. Carl was originally wealthy, but when Eddie accidentally killed the young son of his neighbor he spent most of his money in an effort to cover the incident up; furthering his resentment towards his son. When Eddie was fired in disgrace following the Sin-Eater murder hoax, Carl disowned him and the two haven't seen each other since.
When Peter Parker turned up on his doorstep to ask about Eddie, Carl instantly slammed the door in his face, and when Peter (in his Spider-Man costume) appeared in his office to talk to him, Carl just replied, "Whatever relationship between Edward Brock and myself is no longer applicable", and told him to leave before threatening to phone the police.
After mysteriously giving birth to Eddie's child, Anne Weying left her newborn son Dylan with Carl, promising to return for him. However, Anne committed suicide and for the next nine years Carl raised Dylan as his own son, never informing him of his biological father's existence. One day, Eddie turned up at Carl's house being pursued by purported government agents, but Carl denounced him and let him be captured. When Eddie returned a month later seeking to make amends and start over, Carl reiterated that he did not consider Eddie to be his son and wanted nothing to do with him. When Eddie mentioned that Mary had died, Carl denied having ever had a daughter and punched Eddie in the face in an effort to get him to leave - sending the Venom symbiote into a berserk rage. Dylan witnessed the altercation, and Carl brutally beat him - presumably for pressing him for information on who Eddie was.
Carl took Dylan and forced him into his car, much to the boy's anger. Dylan and his grandfather argued about their views on Eddie, with Dylan respecting and admiring Eddie for not whitewashing who he was. His back-talk enraged Carl, who prepared to strike him, but he was stopped by the Venom symbiote, who sought redemption for its actions. The alien biomass confronted Carl in a mental recreation of the interrogation room he had forced Eddie to lie in, taking on Eddie’s appearance during their discussion. When Carl denied his responsibility for making his son into the man he was today, claiming Eddie’s decisions were his own and made him what he was, the symbiote lashed out at him, taking on its Venom form and screaming that he knew what he was and that he didn’t need Carl to tell him that. The symbiote then told Carl that it didn’t bring him to the interrogation room in order to ask forgiveness or make amends with him, that he was only there to take Dylan away from him and that if it ever saw him again or if he came near Eddie or Dylan, it would kill him. Carl said he understood, and Venom then told him, “You’re going to wake up now. And you’re going to be alone. And then you’re going to stay that way for the rest of your life”. When Carl awoke, he found that Venom had left him alone in the middle of the desert. As he began walking off, he called Eddie’s name before saying he was sorry.
