Venom: 8 Most Powerful Symbiotes

And now we have one of the big guns, Carnage.

Carnage is one of the reasons the revelation that the Klyntar - the name of the symbiote species - are actually generally really nice and cool was such a shock. The idea that such a peaceful race could produce such a horror as Carnage is truly mind-boggling.

But really, you can thank Carnage's first and most famous host for that. Cletus Kasady was already a sick puppy long before he met Carnage. A serial killer with an inexhaustible love for violence and death, Cletus was more than happy to take on the Carnage symbiote and become one of the worst scourges the Marvel universe has ever known.

Carnage is almost impossible to kill, but don't think for a second that the reverse is true. Carnage is faster and stronger than the previous entries on this list put together, let alone normal Marvel heroes. He can come back from almost an injury, and even take over people's minds as shown in Carnage USA. Add onto all of this the fact that he is completely coocoo for coco puffs and you get one of the most dangerous creatures in the entire Marvel canon.
