Simon Trusselan

Simon Trusselan will be the third child of Marceline Abadeer Trusselan and Tai Trusselan. He was seen in Marceline's multiple prophetic dreams from the episode "Eternity". He will be born about eight years after Josh, six years after Evey, and three years before Luna.

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

Abilities
Simon will have demon longevity, just like his mother, grandfather, uncle, and siblings, meaning that even though he will age, he will be immortal.

Trivia
