|Occupation||Former King of the Fire Kingdom|
|Latest appearance||"The Red Throne"|
|Voiced by||Keith David|
Flame King is the former ruler of the Fire Kingdom and Flame Princess' father. He first appears in "Incendium." Jake's mission was to impress him in order to make him let his daughter date Finn. After he thinks Finn kills Jake, he releases his daughter and promptly reveals that she is evil. He later appears in "Ignition Point," viewing a play which turns out to be Finn and Jake trying to warn him about an intended regicide. After he demands that Finn and Jake be executed for apparently disguising "treason" as a play, Torcho and Furnius (his nephews) are discovered as the true conspirators, and they reveal that Flame King killed his own brother (Furnius's and Torcho's father) so that he could take the throne. In "Earth & Water," he was overthrown by his daughter and Cinnamon Bun and placed in the cell lamp where he once held his daughter. In "The Red Throne," the Flame Lord frees him in return for Flame Princess' hand in marriage. After Flame Princess refuses, however, Flame Lord and Flame King have a fistfight and end up imprisoned in the lantern together.
He is much bigger than the other fire people. He wears a copper armor suit, carved with rhombus-shaped red gems in the armor's collar with a bigger pentagon-shaped one in the chest. The limb pieces have horizontal stripes with copper and brown colors and his hands are uncovered showing his hand-shaped flames. His head is similar to a giant fireball inside the armor, there are three holes in the flames that form the eyes and the mouth. His crown has five tips and a red gem in the middle. When traveling greater distances, he gets out of his armor as a flame and the armor follows him to the destination. Unlike his daughter, he does not have a humanoid body.
When traveling greater distances, he shifts out of his armor as a flame. When he reaches his destination, he merges with his armor at the new destination. He is acrobatic as he was able to jump from his balcony seat in the theater, do a full flip in the air and land perfectly on the stage in "Ignition Point." In the same episode, he is also able to teleport or manifest his presence into the flames of his daughter's candles. This ability was shown again in "Vault of Bones," where he teleports his presence into the flames on the stove.
He seems to be very aristocratic. He has a slightly impatient and demanding personality, stereotypical of royalty. He is also very protective of his daughter, Flame Princess. However, since she's left the Fire Kingdom he hasn't appeared to try and bring her home; she refuses to go back to him due to him locking her away in the lantern up until recent times.
He also understands himself as pure evil, having ascending to the throne by killing his brother and understanding that this evil nature exists in all in the Fire Kingdom.
|The following information is from the Adventure Time comic book series.|
It may not be part of the same canon or continuity as the animated series.
He appears in the (non-canon) Adventure Time graphic novel "Playing with Fire," where he continues to try to influence Flame Princess toward evil in a vision. He has made several cameos in the Adventure Time comic, including one instance where he called Ice King "a pa-toot."
- Flame King shares the same voice actor with Chaos from Final Fantasy, Keith David. Coincidentally, both characters are related with fire, destruction and are described as evil.
- In "Incendium" it is revealed that Koala Bears were once his favorite thing in the world, but does not like them anymore after Jake used his powers to impersonate one.
- In "Burning Low" it is implied that he may know Princess Bubblegum, as she was the one who had him put Flame Princess in her lantern. It was later revealed in "Earth & Water," that he knows Princess Bubblegum.
- The reason he has his daughter kept in the lantern was because of her physical instability. Extreme romance would have resulted in disaster for Flame Princess and the world.
- He also did this because he feared that Flame Princess might overthrow him and take his throne as said and seen in the episode "Earth & Water."
- He may know how to speak French, as shown in "Incendium," when he said "Pourquoi"(Why?!) when Jake accidentally killed his jester.
- In "Ignition Point" he reveals himself, as well as everyone in the Fire Kingdom, to be evil. He also confirms that Flame Princess is evil, but admitted that someone could possibly change her to be good.
- At the end of "Ignition Point" he uses his daughter's candles to leave the subliminal message of "evil" while she is sleeping.
- He continued to harass Flame Princess by calling her evil, as seen in the beginning of "Vault of Bones." However, Flame Princess is shown to be aware of his efforts and is more annoyed/saddened than influenced by them.
