Sky Factory

The Sky Factory (referred to as the Flying Factory in the television series) is a steampunk vehicle that travels in the air. Since its debut, it has served as Romeo's primary base of operations, replacing the mobile laboratory.
The Sky Factory has a control room to control the factory, contains various machines such as its metal-sucking nozzle vacuum (referred as the Sucky Sucker), a mounted ray and expels gum clouds to pollute the environment. The Fly Bots take care of the factory for Romeo, while Robette serves as the co-pilot of the factory.
It first appeared in the Season 3 episode "Villain of the Sky," where it turned out to be the source of the expelled black and stinky gunk clouds in the air while it was being finished.
In "Protector of the Sky," Romeo used the factory to spread gunk clouds around the city and suck up everything using its metal-sucking nozzle machine. However, after a minor fight, the PJ Masks managed to stop Romeo by overriding the controls, causing the nozzle to suck up the gunk clouds and mess with the controls. Romeo and Robot tried to go after the team, but they ended up falling off the factory and into one of the gunk clouds, so they could not cause any trouble again that time.
In "The PJ Masks Save Christmas," after discovering he was on the naughty list, Romeo decided to ruin Christmas by capturing Santa Claus in his Sky Factory.
In "Romeo's Melody," Romeo captured a few animals, including Howler, Rip, and Armadylan, hypnotized them with a newly created melody, and had them exercise to create energy for the factory.
In "PJ Robot Takes Control," PJ Robot took control of the Fly Bots and turned the factory into the "Fun Factory."
In "PJ Sky Pirates," Romeo's Lab was being kept in the factory. It was yet to be determined if he will use the vehicle again in the future, although he likely will. This is proven to be true, as the lab was seen "Big Sister Motsuki."
In "The Disappearing Ninjas," Romeo sent his factory to Mystery Mountain.
In "Master of the Moat," Romeo used the Sky Crystal to make his own world in the clouds.
In "PJ Robot Vs Romeo," the Sky Factory was losing pieces and Romeo and PJ Robot, despite not wanting to do it at first causing Robot to initiate psychiatrist mode, decided to work together while the PJs collect stray pieces.
In "Heroes of the Sky," the Sky Factory was used in an available plot to create multiple Sky Factories. Romeo used the power of several moon crystals and the PJ Crystal to build a ray that would, when at the edge of space, make more Sky Factories. However, after the PJ Masks and Luna Girl got back their crystals, the Sky Factories shrunk and fell.
In "Asteroid Accident," Romeo went after the PJ Masks in the Sky Factory in order to get the asteroid back, zapping them in the process. He also zapped the asteroid while the PJ Masks and Newton Star were on it. After Newton was able to surf the rock towards the factory and hit its ray, the invention zapped the factory, sending it spiraling back to Earth.
In "Romeo's Space Machine," Romeo used his Space Machine to suck up all the things from the city.
In "Flying Factory Out of Control," the PJ Masks celebrated Romeo's birthday in the factory.
In "Mission Munki-gu," his factory was taken over by Munki-gu, which later went into space.
In "Robo-Wolf," Kevin was launched into the factory in order to get extra parts for the Wolfy Kids' homemade robot. He stole the new Robot Controller that Romeo invented for Robot and left with Robot in pursuit, but when the PJ Masks arrived to confront Romeo, he accused them of stealing the remote and used his new Truth Ray to make them confess, but to no avail. PJ Robot helped them escape afterwards.
In "Lost in Space," the factory was sent into space after Owlette accidentally launched a set of feathers at it from the PJ Jet. While Romeo made the repairs to return to Earth, he upgraded the computer to come up with a new plan. However, the computer, then named Mabel, took the place over afterwards, along with the Fly Bots, Robette, and the satellites. She was later defeated when the PJ Masks, Romeo, and Robot decided to work together.
In "By My Pharaoh Feathers," Pharaoh Boy took over the factory while Owlette attempted to get revenge on Romeo using her Super Owl Feathers, which he deemed as useless. Initially opposed to the idea, after learning that her feathers had caused the current situation, she finally agreed to help him.
In "PJ Robot Malfunction," Romeo used a robot bug to reprogram PJ Robot so that he'll turn against the PJ Masks.
In "Battle Of The Fangs," after hearing the Wolfy Kids' new band, Romeo offered to be their manager while at the same time planned to use their sound in order to power up the Sucky Sucker and blow the town away. However, after revealing how he truly felt about their music and Kevin sent the factory away with his solo act, Howler and Rip fired him, and Robot, Robette, and the Fly Bots created a new band for him, much to his dismay.
In "Owly Tricks," Romeo captured Owly, then later Alley Cat and Lionel while the PJ Masks were chasing an Owly hologram created by his Hologram Machine, in order to drain their powers for the factory. The PJ Pets managed to escape, and the PJ Masks rescued them afterwards, while stopping the factory from crashing when its controls were damaged in the chaos.
In "Pirate Robot," Romeo planned to create a chef robot, but was interrupted by the ninjas' attack. In the chaos, Night Ninja's pirate hat fell into the machine containing the items needed to create the intended robot, and Pirate Robot was created instead. He briefly took over the factory with Romeo and Night Ninja as his prisoners before leaving.
In "Owlette, the Pirate Queen," Pirate Robot attempted to infiltrate the factory. In one of his attempts, along with him, some unwanted spare parts were dispatched, which were used, along with the pirate ship float, to create the Spanner of the Skies. The vehicle later crashed into the factory while attempting to avoid the tractor beam, sending the latter on a collision course with HQ as the tractor beam randomly fired. Pirate Robot averted the crash by using his cake-firing gun at the beam.
In "Midnight Snack Attack," Romeo captured Pirate Robot, along with Owlette and Gekko, forcing him to cook food for him because it was what he was supposed to be made for. The three escaped through using Pirate Robot's talents together and with the help of Flybot 337B, who decided to join Pirate Robot as first mate Flybot Sally.
In "Flashcar in the Sky," the Speedy Twins plotted to rob the factory so they could make the Flashcar fly. However, when Cartoka stole the Whizzbot 3000, the invention necessary to do so, it was exactly what Romeo wanted so he could control the vehicle and use it as a weapon to take over the world.
In "Heroes Everywhere," Romeo used the factory to capture the Psychoactive Asteroid and get upgraded with a new Tech Suit until the ninjas stole it and then dropped it on the streets.
