Here is a brief storyline of how Eddie Brock turns into Carnage:
Eddie Brock gets mad that J. Jonah Jameson chooses Marry Jane for the job. Eddie Brock goes to Oscorp to ask for help. Norman Osborn accepts his request and unleashes the new and improved Carnage Symbiote on to him. Eddie Brock gets consumed by the symbiote and turns into Carnage.
