Luke Collis Sienkowski (born January 14, 1974), also known as The great Luke Ski or Luke Ski, is a comedy musician, parodist, storyboard artist, writer and voice actor. He currently works in Mighty Magiswords as a storyboard revisionist, writer and occasional voice actor as he is close friends with creator Kyle A. Carrozza who is a fellow The FUMP member and they both have a podcast entitled "Kyle and Luke Talk About Toons" discussing animation topics. His frequently voiced character, Skullivan, debuts in the episode "Cleanliness Is Next to Grupliness" as well as him playing Nyando and a merchant. The first character he voiced, Docky Boardman, made his appearance in the short, Too Many Warriors. He also wrote the song A Bunny Playing Pulled the Lever for the Mighty Magiswords short, The Saddest Little Bunny.
The decapitalization of the words "the great" in Sienkowski's stage name is his own preferred spelling, and the title has appeared as such on all of his albums to date. He had the most requested song on the Dr. Demento radio show in 2002, 2003, and 2011 with his songs "Peter Parker" featuring Sudden Death, "Stealing Like a Hobbit", and "Snoopy the Dogg" respectively.
