Story:
A troubled young man finds himself abducted by a strange alien substance which alters his personality into a heartless, un-controlable menace known as Venom.

Also for those who are not sure of the actor I chose to play Carnage, just know that he`s portrayed psychos before in the past from Silence of the Lambs, Red Dragon as well as Harry Potter 4 & 5(portrayed Voldemort in both films).
