Bio: Dylan was originally thought to be the son of Carl Brock, the estranged father of Eddie Brock (aka Venom). However, it was revealed that the Venom Symbiote had been tampering with Eddie's memories in an attempt to make him appear weaker than he was, so that he would feel like he would always need the Symbiote attached to him. Some of the memories he had tampered with were making Eddie believe that he had cancer (he never did), that he had an uncle Dan that had died of cancer (he did not have an Uncle Dan at all), and that he had an older sister named Mary, who also passed away from cancer (he does not have an older sister named Mary). The other memory that was tampered with? All traces of Dylan were removed from Eddie's mind so that Eddie would never know that Dylan was actually his son (with Anne Weying). The Venom Symbiote was terrified that if Eddie knew he had a son, he would leave it behind for his son.
Eddie has since regained his memories and at least temporarily separate from the Venom Symbiote, enraged that it would betray him in such a manner.
