-Prince of the Shadowland (formerly)
He's a mischievous imp who hails from the Shadowland, and he can use his own living shadow to suck the shadows out of other people, turning them old fast (only the Mask's immune to this) and allowing him to remain forever young (though he's powerless without his shadow). He's over 4000 years old but, in his own words, doesn't look a day over 12 (because of this when he's captured, he's forced to do homework often). He's known everyone who has ever possessed the Mask such as Attila the Hun, Genghis Khan, Blackbeard, Billy the Kid, and Nimrel (a malevolent corruption of Merlin who was transformed into a monster when a magic spell blew up in his face).
He hates Stanley being the Mask, while Stanley's wearing where it's nowhere near as malevolent as he wants. Though he originally decides to leave him alone on the pretense that Skillit will be back when the next Mask wearer comes around.
- Skillet's obviously a parody of Peter Pan (skillet, pan: two kitchen utensil names), specifically the version from Fox's Peter Pan and the Pirates of which Jason Marsden voiced. The similarities include how Skillet dresses the same as most incarnations of Peter Pan and can also fly and has the same immaturity as a 12 year old boy and aside from living in another world, his shadow's able to escape from him.
- At the end of the episode, Enquiring Masks Want to Know, The Mask mentions about Skillit being trapped in the Shadowland for good, or he'll return if the makers of the show let him come back for another episode, (breaking the fourth wall). But, he didn't return for another episode in the second or third/final season of the series, making Enquiring Masks Want to Know Skillet's final appearance in the series.
- In Shadow of a Skillit, Skillit says he hates it when goody-two-shoes (good people) posses the mask of Loki like Stanley Ipkiss, and that "Honest Abe" character, revealing that U.S. President Abraham Lincoln use to possess the mask, and he was the first ever good person to use it. But, since Skillit hates it when good people have the mask, he must be responsible for his assassination at Ford's Theater in 1865 by John Wilkes Booth.
