Jimmy is a policeman in Ninjago City.
Jimmy bolted into the Police Commissioner's office telling him about the phones ringing off the hook. Later, they try to stop the darkness ravaging the city only to find it is an Oni in dark mist. Jimmy, the Police Commissioner, and the officers find themselves surrounded by it, but luckily, the ninja arrive and get them into the Bounty.
Jimmy reports many false or non-important crimes or other things for the ninja to stop. He eventually gets the ninja's help in paper filing for the Police Commissioner.
Jimmy was with another policeman hiding behind a police car when the Merlopians attacked.
