Codex

Codex is a symbiote-bonded villain who emerged during the King in Black saga, serving as a deadly agent within the wider symbiote conflict threatening the Marvel Universe alongside Eddie Brock and Spider-Man.

Bursting onto the scene in 2020 from the creative minds of Donny Cates, Mark Bagley, and Ryan Stegman, Codex is a Modern Age Marvel character who arrived during one of the most ambitious and celebrated runs in Venom's history. Sharing pages with heavy-hitters like Eddie Brock, Dylan Brock, Spider-Man, and Peter Parker, Codex keeps genuinely elite company in the symbiote corner of the Marvel Universe. With appearances spread across Venom, Venom War, and Knull, this character is woven into some of the darkest, most cosmic storylines Marvel has told in recent years. Twenty appearances and counting — Codex is a modern rarity worth tracking down for any fan riding the symbiote wave.
