Seward Trainer was a genetics expert that was in the employ of the High Evolutionary. He was sent to spy on the cloning experiments that were being conducted by the Miles Warren. He became an assistant to Warren himself. However, one night he was caught stealing some of Warren’s files by Scrier, an agent of Norman Osborn. Scrier used this opportunity to blackmail Trainer by threatening to tell Warren about his unfaithfulness. He told Trainer that he would not tell but only if he would serve his needs whenever Scrier requested him. Trainer reluctantly agreed, unaware he was actually a pawn in a much grander scheme.
