The XK-81 Jetpack, sometimes referred to the Jetpack, is a gadget in Ratchet & Clank, invented by Dr. Nefarious on planet Gaspar and used by the blarg. It allows for long-term flight time when full of fuel, which is obtained from green fueling stations on various planets.
The Jetpack was obtained by Ratchet and Clank from the Brain Scientist on planet Gaspar, who granted it in exchange for ten telepathopus brains. It was also used by the other Galactic Rangers.
Use[]
The XK-81 Jetpack is used by holding 
to fly upwards and consume fuel; releasing allows the player to descend slowly. It can only be used when a fueling station is available. Weapons can be used during the flight. The Jetpack has a fuel meter that indicates the percentage of fuel remaining. It flashes red when it is nearly empty and triggers a beeping alert when completely empty. It can be refueled by stepping on a fueling station.
The XK-81 Jetpack is used on Gaspar, inside the warbot factory in Quartu, and the Deplanetizer when defeating Dr. Nefarious, each of which has fueling stations.
