Like all Fairies, Jorgen von Strangle has an Anti-Fairy counterpart that is the complete opposite of him. Jorgen is very embarrassed by his counterpart's pathetic appearance.
Instead of wearing a tough military outfit like regular Jorgen, Anti-Jorgen wears a ballerina outfit. A similar version of him was also shown in a Fairly OddParents comic book, Will the Real Cosmo Please Stand Up?, that is apparently 2.5 inches tall. He is a tremendous sissy who enjoys making macaroni art, and unlike the real Jorgen he lacks big muscles.
He was first mentioned in The Gland Plan, where Normal Jorgen needed a Fagiggly Gland transplant from Anti-Jorgen, and he was first seen in Jimmy Timmy Power Hour 2: When Nerds Collide in a small cameo alongside the Anti-Tooth Fairy, and he made his first actual appearance in Anti-Poof wherein he was shown on a monitor with other Anti-Fairies when Anti-Cosmo was questioning why there was no Anti-Poof. He also appeared in the comic, Will the Real Cosmo Please Stand Up?, when Jorgen was explaining the nature of Anti-Fairies.
