The Headquarters (mostly referred to as simply HQ) is where the PJ Masks meet up to discuss the current situation, who's involved, what to do, and which vehicle to take. The building itself is in the shape and form of a totem pole as a disguise from the public.
HQ is located inside the city's park, on a small island surrounded by a pond. The island itself can be accessed by a bridge.
The Headquarters holds the following vehicles:
Catboy's Cat Car, a high speed motor vehicle used to drive to the situation's location.
HQ consists of 3 rooms, one for each of the PJ Masks. Catboy's room in the center is the one most frequently visited, since it is here that the PJ Masks discuss their missions.
The 3 sections of HQ can rotate independently from each other.
The 3 symbols on the front side of HQ can open up like doors to let the PJ Masks' vehicles out or back in. HQ can also be accessed through a door in the side, from underwater, or a hatch in the roof.
HQ is equiped with the following features:
The PJ Picture Player, a holographic, spherical computer with touch screen control panel. It has many functions and abilities, including controling everything in HQ, controlling the PJ Masks' vehicles, and acting as a surveillance-like camera to find villains easily.
A rocketship function: This allows HQ to take off like a rocket and fly through the air or even into space. When going into space, HQ can actually transform from a Totem Pole into a more spaceship like appearance known as the Astrototem (nicknamed PJ Rocket in U.S. dubs). The controls for this spaceship are located in Owlette's HQ room. The rocket function is for space missions, as well as total disasters and emergencies only.
Fire Furball, a defense mechanism for firing projectile 'furballs'. It is located at Catboy's HQ room. This function can also be used in rocketship mode.
Owl Beam, another defense mechanism for temporarily blinding villains with a bright light. It is located at Owlette's HQ room. Used in "Owlette and the Battling Headquarters".
HQ spin: causes HQ to spin around to deflection projectiles.
The HQ Crystal: a crystal statue that is the source of the PJ Masks' powers. It was first discovered by PJ Robot in "PJ Power Up", and is usually stored in a hidden room of HQ. In "Take Romeo Off The Road", PJ Robot used the energy of the statue to build the PJ Seeker.
PJ Vault: A vault where the PJ Masks store any dangerous devices and items they take from the villains, like the Moon Crystal.
A doorbell: a bell to ring at the ground floor entrance of HQ. Luna Girl was the first to use it, since even the PJ Masks had no idea they had a doorbell.
