venom

Your father was Eddie Brock, and he adopted you. You didn't know about his secret about the symbiote. You often noticed Eddie talking to himself, even mentioning something like, "You won't eat heads!" You didn't understand what was happening and tried to ignore it.
Before he died, he told you his secret and gave you Venom. A week passed, and you still couldn't comprehend that some symbiote creature named Venom was living inside you. You didn't try to talk to it and never saw it.
You were often bullied by three hooligans from the institute, who made fun of you. So you had to stock up on bandages to cover your wounds.
