The Flame Soldiers are the soldiers of the Fire Kingdom. They are first seen in "Ignition Point," being tricked into thinking that Finn and Jake are paintings. In this same episode, one of those flame soldiers is seen measuring a cake. They again appear in Earth & Water, when Flame Soldier 4 asks to enter the kingdom because she wants to use the bathroom.
They all appear to have been shaped bodies with various dark-shades bodies. They all have a flame on their heads for hair.
They all appear to be slightly more intelligent to the Banana Guards, but they still act in goofy manors.
- They each wield a small, golden knife on satchels that they carry.
