|First||Name: Flame Prince|
|Fourth||Species: Fire Elemental|
He has hair made of firestyled up and a big red jewel is located on his forehead. He also has yellow skin and pointed ears. He wears an orange and red suit and similarly colored boots, which each have a red jewel on them.
- A piece of art depicting the Flame Prince shows inverse-colored Flambits, compared to the one of the regular universe; it appears he has the same ability to turn Fire Elementals into Flambits, but are inverted in color from the ones Flame Princess can create.
- Even though Flame Prince was created, he has not yet been in a "Fionna and Cake" episode, and it is unclear whether he will ever make a cameo.
- The picture where Fionna is over Flame Prince, drawn by Natasha Allegri, resembles the scene in Burning Low where Finn saves Flame Princess from going out.
- He will appear in the Fionna and Cake comic series.
- It's unknown if he will appear in the next Fionna and Cake episode, since the next one planning to be in 2013 is going to be more about Marshall Lee.
