The original Bizarro, herein referred to as "Bizarro Superboy", is created by one Professor Dalton's imperfect duplicator ray in Smallville. The unfortunate creature is accidentally destroyed by Superboy. Years later, the blueprints for Dalton's duplicator ray are obtained by Lex Luthor who builds his own version and creates the more familiar Bizarro #1.
This Bizarro creature's physiology is extremely unstable. He is destroyed and turns to dust when he collides with Superboy.
