These two love killing more than they love each other.
One is a former serial-killer bonded to an alien costume that enhances his lust for destruction. The other is a former drug-dealer who spent time in Cloak’s dark dimension, then turned insane, and mysteriously developed super powers that allowed her to turn people around her into an angry mob. Cletus Cassidy and Frances Barrison ladies and gentleman, a match made in heaven.
Their time together is often short-lived, but when they join forces, no one in New York City is safe. No one. Their initial encounter was at Ravencroft, a maximum security institution devoted to the study and incarceration of the criminally insane. When Cassidy escapes by allowing the symbiote hidden within his blood stream to take over his body, he runs into Barrison, who cheers him on as he slaughters everyone in his path. The two discuss their love for chaos, realize they’re the perfect match, and upon this discovery, Carnage and Shriek begin to paint the town red one innocent bystander at a time. It even forced Venom and Spider-Man to join forces in order to stop them.

Even years after their separation – Spider-Man, Venom, alongside Captain America and a handful of other heroes did manage to put an end to the mindless slaughtering of New York – Carnage and Shriek managed to pick up right where they left off.
When personal computer manufacturer Michael Hall revives the alien symbiote to create a new breed organic prosthetic limbs, his plan becomes a nightmare, as a tiny portion of the living organism escapes and once again bonds with an incarcerated Cassidy. In the meantime, Shriek is being transported to another prison, but with the help of her inter-dimensional pet doppelganger – who was also a member of the their kill-squad years ago in New York City – she escapes, and reunites with her rock-star.

Shriek slipped into a coma after battling Spider-Man and Iron Man, while Carange managed to once again slip through everybody’s fingers. There’s no doubt though that if these two lovebirds get together again, their love for killing combined with their bizarre love for each other, will always amount to a crazy, craaazy display of chaos.
