The Thing
The Symbiotes attacked the Baxter building, killing Mister Fantastic, Invisible Woman, and a Human Torch clone. The Thing was found near Stark Tower, after the explosion launched him countless miles. Thing joined Toxin's resistance to avenge his family. He has met up with the Human Torch and has forgiven him, and has become a symbiote host, though it is sympathetic to the resistance.
