O'Doyle is a police officer in Ninjago City.
Noonan and O'Doyle were called to the Ninjago Museum of History following a break-in. They were unable to get a word out of the Night Watchman however so they directed the Green Ninja to him when he arrived. Later, while the two officers were putting up crime scene tape, they were met by a wind coming from inside the building and fled in terror.
The police began chasing Kai's tracking signal, and some police cars took a sharp turn too fast and crashed into a building. Noonan and O'Doyle climbed out of one of the cars, apparently unhurt.
- 45. "Winds of Change"
- O'Doyle and Noonan are always seen on duty together in every episode they appear in, signifying that they are probably good friends or at least partners on the police force.
