Title card gallery
- The first season focuses on the premise's basic features of the show before moving on to the advanced features after this season; these features include:
- Having the show to majorly focus on Tarabiscoville than the show's other newer discovered locations.
- Almost every episode (except for "Gekko Saves Christmas") beginning and ending in the day.
- Showcasing what main motives and personalities the three primary villains have before moving on to their minor motives and moving away from their focus of their traits.
- All of the episode titles have a hero's name, instead of keeping it omitted or having a villain's name in the episode title.
- Season 1's focus is mainly about the introduction of the PJ Masks and their motive on stopping the villains from causing any trouble.
- It should be noted on a meeting with Christian De Vita, he confirmed that a villain named Firefly was intended to appear in this season. But she was scrapped until the producers find a possible use for her later in the series.
- This is the only season in which Jacob Ewaniuk, Alex Thorne, Trek Buccino, and Tristan Samuel voice Catboy, Romeo, Night Ninja, and Cameron, respectively.
