Aloe Mistletoe is a Crest Elemental, otherwise known as a Water Elemental. Like many before her she has taken on an Organic form.

Hundreds of years ago, Finn, the creator of the first dark grimoire, used its powers to turn an oyster and pearl into a powerful item. He used the amulet to capture Aloe while she was in her natural Crest form.

The power imbued to him through the amulet allowed Finn to commit several horrendous acts against his fellow kind, the Crest Elementals.

Upon her release she took on an Organic form to fight to protect the Book of Finn from falling into anyone else’s dangerous hands.
