Anti-Jorgen Von Anti-Strangle is the Anti-Fairy counterpart of Jorgen Von Strangle. Since Jorgen Von Strangle is the leader of the Fairies and the strongest fairy in the universe, Anti-Jorgen is more than likely the least powerful anti-fairy in the universe.
Like all Fairies, Jorgen Von Strangle has an Anti-Fairy counterpart that is the complete opposite of him. Jorgen is rather embarrassed by his counterpart's pathetic appearance, as the more feminine Anti-Jorgen defines how masculine he is. Jorgen almost never talks about him. Jorgen is the strongest fairy and in charge while Anti-Jorgen is weak and just a plain every day Anti-Fairy. Jorgen is a sadistic bully with power both physically and politically, making Anti-Jorgen a spineless weakling in a humiliating position in life. He also acts in an extremely girly manner, which is the opposite of Jorgen's manly behavior. A proper way to look at it is seeing Anti-Jorgen in the shoes of Binky and Anti-Binky in the shoes of Jorgen.
Instead of wearing a tough dog military outfit like regular Jorgen, Anti-Jorgen wears a ballerina outfit. A similar version of him was also shown in a Fairly OddParents comic story, 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 due to being a weakling. In "Jimmy Timmy Power Hour 2", Anti-Jorgen was shown to have big muscles unlike in his other appearances.
He was first mentioned in The Gland Plan where the normal Jorgen needed a Fagiggly Gland transplant from Anti-Jorgen (as it went uncontrollable when he was about to stop Timmy and his friends from taking Anti-Cosmo with them), and he was first seen in The Jimmy Timmy Power Hour 2 in a small cameo alongside the Anti-Tooth Fairy (though here he looked almost exactly like the regular Jorgen with the only difference being the costumes they wear), 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 appears in the comic, "Will the Real Cosmo Please Stand Up?", when Anti-Cosmo was explaining the nature of Anti-Fairies.
