The Inventor Droid is a female droid who is native to Metropolis in Winter Tundra, Avalar. She invents the combined flying and superflame power-up which Spyro uses to defeat the Sheep saucers. After defeating the first challenge featuring the flying saucers, the Inventor Droid gives Spyro an orb and opens a portal back to Winter Tundra.
She then challenges Spyro to defeat the flying saucers in a second challenge, giving him an additional orb if he succeeds. When not talking to Spyro, she will, for some reason, bite her briefcase.
