Arcee is the daughter of the Cybertronian Prime Optimus Prime. She dreams of wanting to be Part of the Planet Earth, even though she is an alien robot. One Night she sees a human named Jack Darby. After a freak storm, Arcee saves Jack from drowning. She sings to him and Jack is mesmerized by her voice. She wants to be part of that world and be with Jack, but Optimus refuses. She reluctantly trades her voice to the Insecticon Witch Airachnid to be a Human. She must kiss Jack before the Sun sets on the third day and turns back into a robot and belongs to Airachnid forever.
