I don't know. Anti-Venom seems to be the only "safe" symbiote to wear. Unlike Venom, it doesn't actually have a mind of its own, although its healing abilities can make a weak person to have a serious "Messiah's syndrome". Besides, it has amazing healing abilities for its wearer and others, like reattach cut limbs (Flash did that). It certainly brings the "inner doctor" of its wearer, so it be a good thing for almost anyone. Besides, Anti-Venom is literally the opposite of Venom, which means it's a LIGHT against Venom's DARKNESS.
