The story of Eddie Brock was expanded thanks to the 2018 feature length film titled Venom, with a sequel in the works that will bring in the serial killer with a symbiote known as Cletus Kassady.

The symbiote that would eventually be known as Riot made his first appearance in Venom: Lethal Protector #4 back in 1993. Using Venom, Dr. Carlton Drake created five symbiotes, one of which was Riot.

With Venom: The Last Dance wrapping up Sony's superhero trilogy, we're finally meeting the symbiote god Knull. Here's what you need to know about this all-powerful Marvel villain.
