Midori has big curly blonde hair. In her appearance in Dragon Ball she wears a pink dress. One notable trait about her appearance is that she looks similar to Akane which Akane used as a prank on Senbei by dressing up as her. During the Penguin Village Grand Prix race, Midori and Akane teamed up and attempted to cheat by having the other hide out far near the finish line to be ahead of everyone but failed because of falling down a cliff.
As a child, Midori went to an amusement park in Metropolis Island with her parents, she got lost and accidentally wandered into a private spaceship belonging to the royal family of Planet Takeya-Saodake. When the spaceship left off to Takeya-Saodake, King Saodake and Queen Takeya who had no children adopted Midori as their daughter. Years later, they found Midori's real parents and returned her to Earth where Midori promised to succeed the throne for them in the future if they ever get old and fall ill.
