Josh Trusselan

Josh Trusselan will be the first 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 nine months after his parents get married, two years before Evey is born, eight years before Simon is born, and eleven years before Luna is born.

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

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

Trivia

 * He is named Josh because when ACat was little, he wanted an older brother named Josh.
