2. Carnage

(Spider-Man, Marvel Comics)

Spider-Man has some pretty crazy villains. And Carnage is the craziest of all of them.

Cletus Kasady was already a terrifying serial killer, and that's before he ever found his way to having superpowers. In jail, Cletus shared a cell with Edward “Eddie” Brock, aka Venom. When Brock’s partner/sentient goop monster the Symbiote broke him out of said prison, the Symbiote was…Well, whatever the sentient goop version of pregnant is.

The Symbiote baby bonded with Kasady, and together they became Carnage, a red blood monster who enjoys murder only slightly less than I enjoy those oreo Cadbury bars.

Carnage verges on being too grim-dark for his own good, but when he's right, he's pretty fun. I'll still fight for Maximum Carnage as Not That Bad, and I'd even call it fun if you caught me on an especially charitable day. But don't get me wrong; the red-clad murder-monster at the heart of it is nuttier than a Payday bar, for sure.
