Their general purpose is to:
Protect and guard anything that is related to the mythology they represent, from anyone corrupting or damaging it which can affect the normality of the night.
Fight against fantasy and folklore-based villains.
Vigilante & Crimefighter Heroes
Some of the nocturnal heroes are typical vigilantes and crimefighters who protect their city from being in danger by villains at all means.
They either have direct connections to sci-fi or (occasionally) folklore.
Their general motives are usually preschool-based:
Stopping villains from ruining the day for other kids, such as disruptions of attending school, birthday celebrations, including robberies involving school books and candy.
Performing rescue plans and liberations such as freeing animals and launching assaults on enemy strongholds.
Some of the nocturnal heroes, however, have genuine superpowers such as their powers originating from a supernatural sources such as a crystal, or a group of asteroids which allows them to transform anytime. While the rest use handheld weapons or have martial arts that are beyond those of normal beings.
Some of the heroes are inspired from existing DC and Marvel superheroes, notably the characters from the PJ Masks who have some design elements based on the Marvel superheroes, as well as Energuman whose design is based on Batman's. While most of the heroes from Les Pyjamasques as a majority are inspired by fantastical and mythological elements, as well as nocturnal animals.
