Symbiote Spider-Man

Once the Secret Wars came to an end, Parker returned to Earth along with the other abducted superhumans and continued to use the black suit. He eventually noticed the costume behaved strangely, so he sought help from the Fantastic Four's Mister Fantastic, who discovered that the suit was a living organism.

He helped remove the costume by force and kept it at the Fantastic Four's headquarters in captivity. The symbiote would later escape, plaguing the life of Parker again and ultimately merging with one of Spider-Man's critics, Eddie Brock, creating the villain Venom. In a climactic fight, Spider-Man defeated this new foe.
