The Headmaster is the (Fake) Headmaster of The Super Moshiversity. He is a member of C.L.O.N.C. He is a Mustachio in disguise (possibly the head Mustachio), and only recently did Elder Furi and the Super Moshis figure this out. Every night (until his defeat) he would play an organ to hypnotise every student in the moshiversity. After being hypnotised, they would go on a rampage and destroy everything. One night, a Super Moshi found him and Defeated him. It is unknown what happened to him after his defeat. He was mentioned in the article by Roary Scrawl about all the previous "baddies" so it is possible he will return.
The Headmaster wears a blue robe, with purple at the arm holes. He has a purple neckhole (much like a turtleneck) and a blue Graduation Hat. He has pinky/purpley hands that look quite like Dr. Strangeglove's glove.
