Amanda

Amanda is a timid, inconfident and nervous person. She's very unfamiliar with planet Earth and due to her alien upbringing she can come off as gullible and dim-witted. She learns from her mistakes very slowly, but she does her best.

Amanda never wanted to leave Pluto, her race's home planet, but she had to move to Earth because this is where her sibling Douglas went. They're the dearest person in Amanda's life and she always looks up to them, although she barely can understand their fascination with everything new. She mimics Doug a lot: she partially adopted their fashion style, she picked a new Earth-like name for herself from an old movie just like them and even her face color became a more cold shade of blue over time.

She still believes that this is not permanent and eventually she will fly back to Pluto together with Doug.
