Luna Trusselan

Luna Trusselan will be the fourth and final child of Marceline Abadeer Trusselan and Tai Trusselan. She was seen in Marceline's multiple prophetic dreams from the episode "Eternity". She will be born about eleven years after Josh, nine years after Evey, and three years after Simon.

Appearance
Luna will have Luna/Marceline's hair, Luna's ears, Luna/Marceline/Tai's eyes, Tai's mouth, and Luna's skin. She will have none of Hunson Abadeer's physical features.

Abilities
Luna will have demon longevity, just like her mother, grandfather, uncle, and siblings, meaning that even though she will age, she will be immortal.
