Pyotr I. Koopa is a big Koopaling, and his name is based off of Pyotr Illych Tchaikovsky, as most of the Koopalings' names are based off of musicians or celebrities.
Pyotr was originally nice until Roy came along and taught him to be evil. Now he likes to steal from his enemies, and sometimes works with Roy or Larry to steal something or fight the Mario Bros.
He is a playable character in this game he is unlocked when you complete Lava Land with Roy. He has special powers in this game like flutter jump, head butt, steal power-up and even graffiti.
Pyotr appears as a starter character with Lavora in this game and must work with her to save all the Koopalings and get Bowser's Big Book of Plans back! In this game, his special powers are magic (standard), stealing power-ups (super), and his paintbrush (mega).
Pyotr pretends to serve Bowser because he wants to take Bowser's spot some day.

Pyotr has a green Mohawk that covers one eye, apparently blue eyes, and a red shell. He is also a large Koopaling.
- In some games, if he is a boss, he is in a snow world, resembling the Nutcracker, which Pyotr Tchaikovsky wrote.
- During the boss fights, if he is in a snow world, music from The Nutcracker might play.
- In some games, if his boss battle is before Larry's, he may steal Mario's hat and won't come back until you battle Larry, due to the fact that Larry likes to steal things that Pyotr has already stolen.
- In some games, the Koopalings or Bowser pronounce his name "Peter" because Pyotr Tchaikovsky was Russian.
