Mayzie is the pilot of the ship, despite being 10 years old. Like Hattie, she is actually trained in what she does, but she's still only a kid and doesn't know what she's doing fully. She is incredibly upbeat and energetic, and always just looking out to have fun. Her big brother is Marcus, who she looks up to dearly. She also sees Hattie as a sisterly figure. She actually likes Ric, but exploits his robot body as a punching bag, chew toy, and various other things.

Mayzie has a little girl's voice.
