Misty is a space thief stealing unique items in the universe, but on a much smaller scale than the Hige-Hige Bandits. She is perceived as arrogant, selfish, and uses others for her own benefit. Birdy has an especially strong dislike for her, because of her lifestyle choice of being a thief. Later on, she finds Zero.
However, as the series progresses, not only does she become less abrasive towards the Jetters, including Birdy, but it is revealed in numerous flashbacks that she had a flirtatious relationship with Mighty, which included flashbacks of him trying to convince her to join the Jetters crew, and to abandon the space thief lifestyle while calling it a "burglar" lifestyle, and not understanding the difference between the two.
However, in another flashback involving a standoff against Mujoe, the badge got broken. Towards the end of the series, she becomes more involved in with the other characters from the sidelines and almost admitted she had feelings for Mighty before she got interrupted by Bonbaa-san. She was responsible for finding Bomber Zero, an android with all the memories, personality and abilities of Mighty, who all the characters initially assumed was Max due to his similar appearance.
At the very end of the series, as a long running sentiment throughout the anime, Mighty left her repaired Jetters badge in his locker with a note, and it is assumed that she joined the Jetters afterwards or left on her own journey.
