Toxin

Bursting onto the scene in 2021's Extreme Carnage: Riot #1, Toxin is a thoroughly Modern Age Marvel creation, born into one of the most volatile corners of the symbiote mythos. With only 16 catalogued appearances so far, this is a character still carving out their place in the Marvel universe — but the company they keep speaks volumes: sharing pages with Venom, Carnage, Dylan Brock, Flash Thompson, and Bren Waters across titles like Venom War and Extreme Carnage Omega puts Toxin right at the heart of symbiote chaos. For collectors tracking the next wave of symbiote lore, this is exactly the kind of early-days character worth watching closely.
