Astro’s face resembles a crescent moon, with half his face being a very light white-ish blue, and the other half being black. He wears a deep blue blanket around his body; snugly covering up his torso and arms. His legs are visible though, and are white-ish blue like his face. He also wears a blue nightcap. The black side of his face has a more star-shaped eye than the white side.
Astro is quiet and reserved, but not necessarily super shy. He just doesn’t enjoy too much attention.
