Perhaps one of the most terrifying villains of all time, and surely one of the most terrifying of the Spiderman villains, Carnage is far from a normal run of the mill law breaker. Carnage was spawned when Cletus Kasady, a vicious serial killer bonded with an alien predator.

This bonding created one of the most vile and evil creatures that Spiderman has ever encountered. Rather than hoping for fame or fortune, Carnage wishes for a society where every being is allowed to do exactly as they please; no law, no rules and no consequences.

Because Carnage is half alien, or symbiote, he has some pretty special abilities including superhuman speed and strength, out of this world stamina and agility, and lighting fast reflexes. This makes him one of the toughest Spiderman villains ever.

One of the things that makes this guy even more terrible is that he has an immunity to Spiderman's spider sense. So, when the attacks from Carnage come, Spiderman is usually caught off guard.

Kasady comes from a violent background, probably more violent than all of the Spiderman villains, as Kasady claims his father brutally murdered his mother.

He has also told his doctors that he killed his own grandmother, and tortured his mother's dog, causing her to in turn want to murder him. With an upbringing like that, what do you expect? By his early twenties, Kasady was convicted of more than 11 murders, but had killed even more than that.

This character is a blend of insanity, evil, and pure and deadly abilities. The combination of these things is what makes Carnage a character that Spiderman fans want to keep an eye on.
