As one of the most experienced and senior Skylanders on the team, Jet-Vac is loyal and bold. At first he was unable to think outside the box, unwilling to deviate from the plan (if he has one).
It wasn't until his conversation with Master Eon that Jet-Vac began to act on his impulse to respond to emergencies. Like his in-game counterpart, when started or stressed, Jet-Vac tends to lay an egg, which he hates and frames on his room as a constant reminder of his failure.
The Sky Baron has also not quite caught up with modern slang and uses several outdated expressions, and as a result is annoyed with the constant change and maintenance of technology.
As a youth, Jet-Vac said he was like Spyro: talented, arrogant, dumber than all [his] teammates, and acted on instinct without regard to rules. Everything changed when he lost something that meant the world to him, his teeth.
His father also came from a military background and had standards far too high for the professor to achieve, which caused him self-respect issues.
Biography
Noble, selfless and courageous, Jet-Vac is a golden eagle. As the main leader of the Skylander team, this former flying ace is also a badass, using a drill sergeant mentality to impose his vast knowledge of Skylands on the younger members of his team.
And if that doesn't work, he's always got his trusty jet vacuum to intimidate them - with its incredible wind-blasting power, it's enough to send even the most dangerous villains soaring through the skies.
Ironically, the only one who can really ruffle Jet-Vac's feathers is Spyro, whose arrogance often causes them to butt heads. And even though Jet-Vac tries to keep a stiff upper beak, he'll often accidentally "drop an egg" in the middle of a high-stress situation - fighting bad guys, saving bystanders, or keeping his students quiet for a while. test, much to his embarrassment.
