One of the upgrades includes the combination of said vehicles into a new aircraft, the PJ Jet. Another vehicle, known as the PJ Sub, is also introduced. News articles mentioning a PJ Masks traveling exhibit by eOne for Sea Life aquariums (most of which are now closed due to the pandemic) mention that the season will also feature new underwater missions. This season introduces Newton Star, the first, full-bodied appearance of Octobella, Percival, Pharaoh Boy and Munki-gu, the latter of which have first appeared at the 2020 New York Toy Fair. Both the first and fifth mentioned characters have had their designs revealed at the aforementioned Toy Fair, while the second and third characters' CGI designs were revealed on YouTube, and the fourth character had his design revealed in the activity page on the official website. As of this season, adapted versions of characters from the book series (aside from the PJ Masks, Romeo and Santa Claus) will now appear in the television series in order to remain faithful with the book series (e.g. Pharaoh Boy being an adaptation of Apophis). Kyle Harrison Breitkopf, who was the voice of Gekko for three seasons, was replaced by Benjamin Hum. Other voice actor replacements include: Cristian Perri, the Season 3 voice of Armadylan who was replaced by Avery Esteves, starting with the episode "Master Fang's Secret." Armadylan's early Season 4 voice was quickly replaced by Christian Campbell, starting with the episode "Octobella's Garden." Kaden Stephen, the Season 2-early Season 4 voice of Howler who was replaced by Matthew Mucci, starting with the episode "Munki-gu in the City." As of this season, Addison Holley and Brianna Daguanno have retained their voices of Owlette and Luna Girl, respectively, for four seasons straight. This is the first season to have the season premiere on the Disney Junior channel. As of this season onward, the episode format is retooled to change the plots to feel more serious and detailed compared to its childish plots in the first three seasons of the series. Other adjustments include having every episode ending in the nightime, having a special episode at the beginning and end of each season, introducing new characters periodically in interval parts of a season (compared to introducing new characters all at once in the halfway point of a season), include more episodes that focus on the entire PJ Masks, and focusing less on the original three nighttime villains due to the large amount of villains in the series. HQ introduces its basement in this season. The PJs (with the exception of Owlette and PJ Robot) get their own PJ Wings. This is the first season to have twenty-five episodes. Still, there were 52 segments. References
