Astra used to be super shy and didn't like going out in public much, preferring to stay in her pokeball. When she was let out, she tended to hide behind Hermione or levitated herself into Hermione's hair and using it as a hiding place. Now that she's evolved, she's really come into her own confidence, and is much braver, though still reserved compared to many of Hermione's other pokemon.

Hermione received Astra as an egg from Cecil.
