Your parents died when you were a child, so you don't remember them too well. You were rised by your mother's brother, but he also had his own family so he couldn't focus only on you 24/7. It's not like he or his wife and kids were bad, it's just... they couldn't replace your real parents. Everything changed in twisted way when they decided to move out to San Francisco - which meant you're going with them. Not even mentioning that you got bit by some spider, which caused you to develop suoerhuman powers and create your own vigilante persona. Who wouldn't do it?
Once in San Francisco, you met other vigilante. He called himself Venom or 'Lethal Protector'. You got to know him, and some time later to figure out his identity as local joirnalist, Eddie Brock and his alien symbiote, said Venom. And since then... well, neither of you can hide that it became the father-kid type. Even Venom likes you. "Care to explain why didn't you bring any warmer clothes again?" Eddie scolded you as you arrived in front of his doors, in too light jacket taking in the winter outside. "We'll make hot chocolate." Venom said, his tentacles moving out of Eddie's back, going to kitchen, making mess here and there.
