His name seems to be lost in history but what is known about the superhero now known as Venture is that he is virtually immortal and has lived many lives throughout history. He changes his identity from time to time but has been a hero during each of his lives, yet doing so in secret. It isn't until the modern day that his identity is discovered by reporter Reggie Baxter that anyone truly learns what he can do. Reggie is searching for his big story and accidently captures Venture on film saving his and another person's life. Reggie blackmails him into openly became a superhero as he has hidden the tape showing him saving lives in his civilian identity. Venture shaves his long hair and beard (but wears fakes to keep his idenity secret) and doning a costume debuts as the hero he always has been.
