The narrator is an unknown male voice that is heard in each episode. He is known for saying his signature introduction sequence:
- "Night in the city, and a brave band of heroes is ready to face fiendish villains to stop them messing with your day.
- "Connor becomes: Catboy!"
- "Amaya becomes: "Owlette!"
- "Greg becomes: "Gekko!"
- "The PJ Masks!"
An alternate version of his introduction sequence took place in "Catboy vs. Robo-Cat":
- "Night in the city, and a brave hero is ready to face fiendish villains to stop them messing with your day."
- "Connor becomes: "Catboy!"
- "The PJ Mask!"
The narrator has never been physically shown in the series.
- His catchphrases have been altered and said with a different tone in some episodes.
