when wolverine and venom fights, he always run circles around venom. Wolverine has the capability of beating venom, just like venom has the capability of beating wolverine. The fight would be based off of carnage and cyber, whoever wins out of them two is the deciding factor and i do think that cyber could beat carnage.
Venom and Carnage have far superiority in offense, and Cyber and Wolverine have the defense, THe 2 could just throw a tank on wolvie and cyber and ko them.
Wolvie and venom haven't fought enough times to rely on wolvie running circles around him, venomn could just maat his symbiote on the ground, or suffocate him with thesymbiote, more of carnages' style.
