Hmm, This match is for the big boys.
I mean, come on. Venom is max 70 tons, Carnage max 75 tons and Toxin is little above them because his symbiote hasn't bonded with him permanently yet (Or has it?)
Symbiotes are very durable against physhical damage, just like Juggernaut and Hulk are. Hell, I'd even say their durability to punches and other blunt force trauma is nearly equal!
But Hulk and Juggernaut are just too tough to take out by physhical damage the symbiotes can dish out. I doubt Venom was beating Juggernaut's ass, but he didnt even try to. He just throwed Juggernaut around, Juggernaut wasnt able to do anything to him at this moment. Though something tells me, that this Juggernaut wasn't fully powered.
Same goes with the Superman fight, he was depowered. (at least his physhical strength).
The symbiotes have only small chance of killing or KOing the giants. Leading their symbiote tendrills through Hulk's and Juggernaut's noses and other "holes". Something tells me, that a tendril through Brain is enough to kill/KO even a Hulk Or at least turn him back to Banner. (Maybe even Wulberine 😮)
I doubt the symbitoes can work as a team so I'm giving this 9/1 (maybe 8/2 if the symbiotes can work properly together) for the brickheads.
I know I'm a biased symbiote fan, but I try to look from each perpective.
PS. Modern Juggs would lose to VEnom 😄
PSS. It's "good" to see that even senior member can be ***holes and so damm ignorant)
