Professor Popov is a dance teacher at Royal Preparatory Academy.
- Sofia the First: Once Upon a Princess
- Sofia the First
- He has a Russian accent, although Popov's true heritage is unclear.
- He looks similar to Sir Gilliam, the derby instructor at Royal Prep, which might explain why Jim Cummings was credited as Popov in "The Shy Princess" (season 1, episode 6), although Sir Gilliam didn't speak in that episode. Cummings was also credited as Popov in "Substitute Cedric", and while he didn't appear, Sir Gilliam did appear in the dance room, instead (although, this was a mistake, as he was already trapped in the clock tower at the time).
