If I'm not mistaken, in the Animated Spiderman series (mid-90s one I think) it had Carnage merging with Spiderman from an alternate reality in the final episode, and the bond was unbelievably destructive as it used a weapon to attempt to destroy all possible realities. Carnage seems to be chaotic as a whole.
