In Glitchtale, Chara is a male. However, he is still a child (no older than 12-13) and shouldn't sound too different from most Chara voices. Chara example: https://youtu.be/HQ1Q4XEstSE

Chara is best described as snarky. The only exception being for his family (the Dreemurrs) where he displays a softer tone. But his most defining trait is how unmovable he is. Which eventually gets in the way of relationships.

He also gets into some fights, so be prepared to do grunting/screaming should you get the role.

Role: Chara is a main character and has major roles in all three episodes.
