Trivia: Planet Sheen
- Franchise Killer: Is most likely one for Jimmy Neutron.
- Hey, It's That Voice!:
- Name's the Same: Dorkus is also the name of a secondary Jimmy Two-Shoes character.
- The Other Darrin: The Latino Spanish dub was recorded in Venezuela instead of Mexico. This meant that Sheen was no longer Irwin Daayan.
- Screwed by the Network / The Firefly Effect: Once the abysmal ratings and reviews for the first three episodes came in, Nickelodeon proceeded to air the episodes out of order and then move the series to Nicktoons after it was clear to them the series wasn't performing the way they hoped it would. It was promptly canceled after the 24th episode aired... with the latter two being aired months earlier.
- What Could Have Been: The show was originally going to be more serious. The Emperor was evil, Aseefa was the leader of a resistance group, and Sheen was a double agent working for both sides. This was changed because it was too close to Avatar.
