Venom is a Symbiote, a creature capable of infusing itself with its host body. He is one of the villains Heinz Doofenshmirtz recruits to take over the Tri-State Area.
Venom has a black body that resembles the Symbiote he originated from. He has white eyes with no pupils, sharp yellow teeth and a long tongue. A huge white spider is printed across his chest. Exept for the teeth, tongue and black and white color-scheme, he resembles Spiderman.
Personality and traits
Eddie Brock: The Venom Symbiote's current host [as of Amazing Spider-Man #300 (1988)]. After the symbiote left Peter Parker, it bonded to Eddie Brock and the two formed Venom.
Peter Parker: Peter Parker was the first person to find the symbiote in Marvel Super Heroes Secret Wars #8, when his costume was all torn up. It bonded to him and formed a new costume. The symbiote eventually left Spider-Man in Amazing Spider-Man #300 (1988) and bonded to its current host, Eddie Brock.
Of all the villains in the special, Venom has the least number of lines, possibly due to Danny Trejo's busy schedule.
