- Her heritage is inspired by the saying "Davy Jones' Locker", which is used when someone dies due to drowning, falling to the bottom of the ocean, or Davy Jones' locker.
- However, the saying itself is inspired by Davy Jones, an underwater demon that terrorized sailors as it represents all the evil spirits of the deep, Jones being the reincarnation of the biblical prophet Jonah's corrupted inner evil. 
- In Haunted, Vandala actually makes a reference to Davy Jones, but says: "Davy Bones" instead of Jones, saying "Finding Davy Bones' treasure."
