their existence a secret from the people of Retroville. Meanwhile, Professor Calamitous, a major villain in Jimmy's universe, unleashes a surge of anti-fairies from Fairy World that threatens the rotation of Timmy's Earth. Jorgen von Strangle, the powerful fairy commander and enforcer of Da Rules, gets increasingly frustrated by both Jimmy and Timmy's friends and their manipulation of fairy magic. In addition, Jorgen is forced to work with Calamitous after he is betrayed by the leader of the anti-fairies, Anti-Cosmo. The Jimmy Timmy Power Hour 3: The Jerkinators (2006) In their third and final encounter, Timmy and Jimmy make amends while trying to defeat the enemies from their own universes—including a monster that they concoct together—while accidentally rejecting their respective friends in the process, including Cindy. Initially, they are unable to make the monster evil enough to fight them properly, but when they succeed, he almost immediately turns against them and absorbs Cosmo and Wanda's magic and Jimmy's intelligence, and then begins destroying both children's universes.
