Viper's sole appearance was in the Pokemon Chronicles episode "Training Daze". He trains new recruits for Team Rocket and administers the entrance exam. Jessie was a particularly difficult student of his, but he remained certain that she had great potential and refused to give up on her. He answers directly to Giovanni and appears to be a respected member of the organization.
