In the Oh Yeah! Cartoons episode, "The Zappys," Jorgen has a Godkid named Winston but was never heard of again in the series. Although the evidence shown in Temporary Fairy may explain why Winston is not his godchild anymore.
He does not like to wear upper attire that does not reveal his biceps, as shown in Pixies Inc..
While technically every fairy has some powers of warping reality, Jorgen has shown he can do so in the form of a story, shown when he read a story to Binky when he was sick, and it caused Timmy, Wanda, and Cosmo to be the characters of the story, as shown in Timmy the Barbarian.
In a non-canon joke shown in the School's Out!: The Musical bloopers (which can be found on YouTube), Jorgen actually speaks with a British accent during the scene where he says "But first this frappe mocha" someone put a mouse trap in his drink. Jorgen later says in a British accent, "Ok, yes, ha ha, very funny. Now which one of you chaps DIES for this?".
His closest friends are Wanda, Cosmo and Timmy as revealed in "Teeth For Two ". (Although he says he has lots, they're his closest friends.)
He once became Timmy's temporary fairy when Cosmo and Wanda were too busy taking care of Poof.
Jorgen's role as an intimidating antagonist was dwindled greatly over the years, while he can still be an antagonist at times, he became more of a supporting protagonist due to him assisting Timmy and his fairies many times due to certain moments of crisis.
Jorgen appears to be the largest fairy currently in Fairy World. In "Wishology!", it is revealed that fairies used to be warriors in ancient times, and they were much larger than the current fairies. This may account for Jorgen's large size, though the occusation that he is one is more of a suspicion by fans and has not been proven.
He is one of the only fairies in Fairy World without wings and therefore cannot fly without his jet pack.
Ironically, as the series progressed, Jorgen never used his jet pack. And it has not made an reappearance since the 2nd Jimmy/Timmy crossover special, "When Nerds Collide."
It is proven that Jorgen finds other means of transportation without the use of magic. Especially when there's no magic left in Fairy World. This is shown in "Crocker Shocker."
In Action Packed he was the main villain due to the wish Timmy makes.
