The Nasties

The Nasties, a quintet of bullies led by Slip (who is played by Jack Black) are the main villains of "The Neverending Story III: Escape from Fantasia" (the only film in that trilogy to have no Atreyu and to get a G-rating). They have been repeating the twelfth grade and enjoy picking on the protagonist, Bastian Bux.

First, the Nasties trap Bastian in the boiler room and get expelled by the janitor for this. Later, as they are looking for Bastian in the library, they manage to find "The Neverending Story" and they are amazed by how anything that is already happening being in the book (particularly Slip). Because of this, they decide to make bad things happen to Bastian in the story. As Mr. Koreander is coming, they leave the mess, causing him to think Bastian made the mess.
