Toxin (Patrick Mulligan) He is the third major symbiote of the Spider-Man series, the eighth known to have appeared in the comics outside of the Planet of the Symbiotes storyline, and the first symbiote that Spider-Man considers an ally.
Toxin possesses the “unique” special abilities of his two symbiote predecessors; He can stick to walls, can change his identity to that of a completely different person and also has unlimited webbing. His suit is red from the abdomen up and blue from the abdomen down. Toxin can also blend in with its surroundings and become undetectably camouflaged, an ability he gained from his grandfather, and he can form solid weapons from his limbs, an ability first seen in his father. Toxin also seems to have some sort of quick-healing ability like his predecessors, as his wounds from his first battle with Razor Fist healed remarkably quickly. Unlike the others, Toxin can track anyone, not just other symbiotes or symbiote hosts, as long as he has something to begin from, within the entire city of New York and possibly further.
Unlike many of the other symbiotes, Toxin does not try to take over the mind of his human host. Instead, the symbiote actually thinks and voices its opinions to the human host (as evidenced in Toxin’s Cut to the Chase storyline). The symbiote usually speaks when the host is in his “human form”, and acts very immature and childlike because of its nascent existence, once refusing to aid Pat in battle until he apologized for an earlier argument. In addition, he seems to have a stronger resistance to sonics and intense heat compared to Carnage, though this does not mean that Toxin is more resistant to violent urges: it can get carried away with violence and fighting crime, even if it’s a petty crime. When he’s not angry or fighting, Toxin is slim and smooth-lined, although still well muscled, closely resembling Carnage or Spider-Man in his symbiote costume. When he becomes upset or aggressive, he grows into his much bigger and stronger form (like Venom), with vicious fangs and long curving claws
