How To Dress Like Venom
Venom Hallowen Costume
You can also refer to the Venom Symbiote itself, a symbiotic organism from another planet that feeds on adrenaline and gives its owner spider-like powers.
Since symbiotes are not exclusively tied to one being, a number of people have worn the Symbiote over the years, taking the name "Venom" with them. Notable among them is the former Army Ranger Lee Price, who used the Symbiote earlier to make a career as a super villain. Army Corporal Flash Thompson, who formerly used the organism as agent of the US government and member of the Guardians of the Galaxy; and career criminal Mac Gargan, who operates with the Symbiote as a member of the Thunderbolts and the Dark Avengers.
