The symbiote of which Cletus Kasady is host provides him with numerous spider-like powers. Even without the symbiote, Cletus is still considered very dangerous, as his Antisocial Personality Disorder and obsession with chaos make him impossible to reason with and he has no trouble with killing with no motive.

Red Symbiotic Costume: Kasady possesses various superhuman attributes as a result of bonding with the Carnage symbiote, which covers his body in red and black biomass. Most of his powers are similar to those possessed by Spider-Man and Venom, although he possesses several unique abilities. For example he can see out of every bit of his symbiote.

Superhuman Strength: Carnage is superhumanly strong. He has shown himself to be stronger than Spider-Man and Venom combined and can lift about 80 tons; this is not his true limit as his strength increases with his size and variable muscle mass. Kasady himself, however has the strength of a regular human being.

Superhuman Speed: Carnage can run and move at speeds superior to those of any normal human being.

Superhuman Stamina: Kasady's musculature generates considerably less fatigue toxins during physical activity than the musculature of an ordinary human. He can physically exert himself at peak capacity for about 24 hours before the build up of fatigue toxins in his bloodstream begins to impair his function.

Superhuman Agility: Kasady's agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete.

Superhuman Reflexes: Kasady's reflexes are similarly enhanced and are superior to those of the finest human athlete, and even superior to those of Spider-Man.

Superhuman Durability: The tissue the symbiote is composed of renders Kasady's body much harder and more resistant to physical injury than the body of an ordinary human. Kasady can withstand high caliber bullets, great impact forces, powerful energy blasts, and falls from great heights without sustaining significant physical injury.

Regenerative Healing Factor: Despite this, however, it is possible to injure him. Kasady is able to rapidly regenerate damaged bodily tissues much faster and more extensively than an ordinary human. It isn't known, however, if he can fully regenerate severed limbs or missing internal organs, although he appears to have regrown the lower half of his body. In the Microverse, Carnage was able to regrow his entire body from his severed head after being decapitated by Venom, and regrow his head completely in a matter of seconds after having it blown off by Alice Gleason. Kasady is also immune to the effects of all Earthly diseases and infections as long as he remains bonded with the symbiote.
