Adventure Time: Distant Lands - Obsidian will see Princess Bubblegum and Marceline head out on a mission to the Glass Kingdom to prevent a catastrophe. There they’ll meet Glassboy, who will be voiced by Michaela Dietz (perhaps best known as Steven Universe’s Amethyst), who moderated the show's Comic-Con@Home panel, which was featured as part of IGN's Comic-Con@Home livestream.
The panel only reveals a few key details about Glassboy, who is a new character for Obsidian, but we can exclusively reveal the official character description: "Glassboy is a young bookworm living in the pristine Glass Kingdom. Taunted by his fellow Glass People for the sizable crack in his head, he seeks a remedy to his condition and ends up accidentally waking an ancient enemy. To save the day, Glassboy seeks out the hero who once defeated the monster, the legendary Marceline the Vampire Queen."
