DJ Drowsy Drawers
Female robot musical supervillain opponent of Captain Underpants from the "Captain Underpants and the Dreadful Debacle of DJ Drowsy Drawers" episode (13 July 2018) of Netflix series The Epic Tales of Captain Underpants. She plays boring music and puts people to sleep. Originally a comic book creation of school kids Harold and George, she becomes real when mild-mannered music teacher Ms. Hurd is transformed into the character, somehow.
Voiced by Tress MacNeille.
Also in the episode uber-nerd Melvin invents a robot DJ, the Raise-the-Roof-O-Tron 2000.
