Skillit is a recurring antagonist in The Mask: The Animated Series.
He was voiced by Jason Marsden.
Skillit is a naughty and mischievous imp who hails from the Shadowland, and can use his own living shadow to suck the shadows out of other people, turning them old fast (only the Mask is immune to this) and allowing him to remain forever young (though he is powerless without his shadow). He is over 4,000 years old, but (in his own words) doesn't look a day over twelve (because of this when he is captured, he is often forced to do homework).
He has known everyone who has ever possessed the Mask such as Attila the Hun, Genghis Khan, Blackbeard, Billy the Kid and Nimrel (a malevolent and odious corruption of Merlin who was transformed into a monster when a magic spell blew up in his face).
He hates Stanley being the Mask, as The Mask (while Stanley is wearing it) is nowhere near as manipulative 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.
- Skillit is obviously a parody of Peter Pan (skillet, pan: two kitchen utensil names), specifically the version from Fox's Peter Pan and the Pirates which Jason Marsden voiced. The similarities include how Skillit dresses the same as most incarnations of Peter Pan and can also fly and has the same immaturity of a 12-year-old boy and aside from living in another world, his shadow is able to escape from him.
- At the end of the episode "Enquiring Masks Want to Know", The Mask mentions Skillit being trapped in the Shadowland for good, but he will return if the makers of the show let him come back for another episode, (breaking the fourth wall). However, he did not return for another episode in the second or third/final season of the series, making "Enquiring Masks Want to Know", Skillit's final appearance in the series.
- In the episode "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 Abraham Lincoln used to posses the Mask, and he was the first ever good person to use it. Since Skillit hates it when good people have the Mask, he likely is responsible for his assassination at Ford's Theater in 1865 by John Wilkes Booth.
