Jet-Vac is known as the greatest and most daring flying ace throughout his homeland. He is also very noble, having sacrificed his wings to a mother in order to fly her children out of harm's way when their home was attacked.
Jet-Vac was the greatest, most daring flying ace in all of Windham. He was given his magical wings when he was young, as was the tradition for all Sky Barons. But when his homeland was raided, he chose to sacrifice his wings to a young mother so she could fly her children to safety. This act of nobility caught the attention of Master Eon, who sought out the young Sky Baron and presented him with a gift - a powerful vacuum device that would allow him to soar through the skies once again. Jet-Vac accepted the gift with gratitude, and now daringly fights evil alongside the other Skylanders.
Jet-Vac was in a training session with Spyro, Drill Sergeant, and Trigger Happy generated by Master Eon. After the session ended with Spyro accidentally unleashing a jet of flames at Trigger Happy and Drill Sergeant, the Sky Baron noticed that Spyro was feeling down about not being able to master his Daybringer Flame technique, and Jet-Vac reassured Spyro that the dragon can't be good at everything.
The Sky Baron later went with Spyro and Drill Sergeant to the Desert of Columns to save the Molekin, Diggs, from a strangely familiar giant troll. Kaos soon arrived, saving the day by 'vanquishing' the monster with a magic staff after claiming to have turned over a new leaf by defeating evil doers.
When the Warrior Librarians of the Eternal Archives arrived at Eon's Citadel, Jet-Vac, along with Trigger Happy, jokingly complimented on Spyro's legendary status after the Lead Curator, Wiggleworth, recognized the young dragon and recalled reading Spyro's heroic exploits from the Scrolls of the Ancients. The Sky Baron stayed behind at the Citadel when the other present Skylanders went with the Librarians to protect the Eternal Archives, and he later helped his fellow Skylanders in repairing the Archive Walls after their battle with Kaos.

Like Spyro, he joins to defeat the enemies from taking over the other worlds. He doesn't show much on missions.
