Vampire King

The Vampire King was the former ruler of the Vampires until Marceline killed him. He and his court are the main antagonists of the miniseries Adventure Time: Stakes.

Appearance
The Vampire King has the appearance of a large, muscular man with animalistic features, including a face resembling a lion's, scaled, reptilian hands, birdlike feet and a forked tongue like a snake. He wears a white suit, a wine-red cape and a crown resembling the branches of a tree or bush. Jake describes him to look like a stop sign coming out of a loaf of bread.

After his vampiric essence was extracted at the end of Checkmate, he was divided into two beings: His mortal self was restored to its original form as a seemingly mundane lion, while his vampiric essence became a cloud monster resembling a lion with long, spindly legs and snakes growing out of his head.

After Marceline absorbed the cloud with her demonic powers, the Vampire King appeared to Marceline as a mental projection, appearing as a miniature version of his vampiric self.

Personality
Despite being the ruler of vampires, the Vampire King has an odd, somewhat eccentric and silly demeanor. He appears to like animals a lot, and is seen dancing with a cow shortly after his return. He is also accompanied by several animals throughout the mini-series.

He is not without a darker side, as he acted considerably vengeful and cruel after Marceline had killed all of his fellow vampires in the past. As a sort of punishment, as well as an attempt to continue his species, he bit Marceline just before he was destroyed. In the current time, he seems apathetic to being a vampire and later admits to wishing to be rid of his vampirism. He also doesn't appear to care much about his fellow vampire brethren, as he made no attempt to stop them from going on their own.

His pure, vampire cloud-like half appears to be largely mindless and violent, seeming only to desire to consume and turn others into vampires. His mortal lion half, on the other hand, appears to be just a normal animal.

Trivia

 * Jake described him as "an angry stop sign coming out of a loaf of bread."
 * He is playing a Harmonica in "Vamps About".
 * He is based off of the tenth tarot card, Wheel of Fortune, which represent change and taking action, as that change is inevitable and we don't always have have control on our path, but we can decide how to respond. Similarly, the Vampire King accepted that the times changed and being a vampire is no longer worth and asked for Marceline to help to remove his vampire juices. It also represent destiny, as it could be interpreted it was Marceline's destiny to remain a vampire for the rest of her life. The same thing can be interpreted with the reversed form of this card, that represent lacking control, setbacks, confusion, ongoing struggle, as well bad luck, all talking about Marceline's being unable to change her status as a vampire, even after going all the trouble to defeat all the vampires once more, as she didn't made any progress but moved back to where she was. Another connection to Wheel of Fortune, many of the creatures that appear in the card are represented in Vampire King's body, such as a lion (head), a human (torso), a bird (feet) and a snake (hands), as well the Sphinx, which is a mix of all those beings.
 * He also greatly resembles Vincent from the 1987 TV series Beauty and the Beast in both looks and personalty. Vincent was portrayed by The Lich's voice actor Ron Perlman.
 * He is the one who turned Marceline into a vampire.
