Trivia: Princess Tutu
- Fan Nickname:
- Fakir's often called Fail Knight by fans.
- Guitar Ninjas: anything which is unexpectedly and incredibly epic, though most often used in reference to the second season of the series itself.
- Mytho's tendency to have plot-relevant conversations with Fakir while wearing nothing but a nightshirt has resulted in him being christened the Pantsless Wonder.
- Hey, It's That Voice!:
- Femio's character bears quite a lot in common with the character of Tamaki Suoh from Ouran High. Vic Mignogna voices both, albeit he manages to sound quite different in Ouran.
- Other noticeable actors include Luci Christian as Duck, Chris Patton and Takahiro Sakurai as Fakir, and Jessica Boone and Nana Mizuki as Rue.
- Pike is voiced by Sachi Matsumoto who voiced Link (in The Legend of Zelda: The Wind Waker, The Legend of Zelda: Phantom Hourglass and Toon Link in Brawl) and Skull Kid from the same franchise (The Legend of Zelda: Majora's Mask and The Legend of Zelda: Twilight Princess).
