The Moon

The Moon is a member of the Vampire King's court in the Adventure Time miniseries "Stakes."

History
The Moon was staked by Marceline Abadeer to protect the last remaining humans.

She returned after Princess Bubblegum drained Marceline's vampire essence. She heads towards a lake leaving moon pearls wherever she goes. When Marceline got poisoned Bubblegum ordered Finn and Jake to find the her and take her back to the candy kingdom, but they thought she said for them to stake her back. They found her sleeping in a basket in a boathouse, but when the sun goes down she wakes up and starts chasing them to the candy kingdom. She was hard to kill because of her healing powers, but when she got close to Marceline she was able to suck the Moon's soul, curing her poison.
