The world of comic books is completely filled with interesting and novel concepts and characters. One of the better ideas that has sprung up from the Marvel Universe is the symbiotes. The symbiotes started with Spider-Man's black suit in the '80s, which quickly morphed into the famous Venom. Venom spawned countless others like Carnage, Sleeper, and many more. Almost every big-time Marvel character has been bonded with a symbiote, at one time or another. However, they are an entirely Marvel creation, so no DC characters have yet had the honor.
