Mighty Orbots
Earth: the 23rd century. A time of robots and aliens. And of destruction and terror! Can the Galactic Patrol, defender of the United Planets, stop the evil computer Umbra? You bet they can!

Ohno begins to doubt her worth because she's ""just an Orbot."" Shadow agent Plasmus turns her into a human at her request, but when Mighty Orbots is needed on a rescue mission, Ohno finds she can't change back and as a result, can't activate Mighty Orbots!
