Beta is a Female Resistance leader long before the Great War Season 3 Episodes "Forever is a Long Time Coming"...
Beta began existence as one of the Quintessons' many robotic slaves. She would not remain so. In the course of time she became a warrior, armed with a powerful crossbow weapon, and standing beside her partner A3 she would be a leader in the rebellion that freed Cybertron from its Quintesson masters.

Made from TMNT April O'neil, arms and crossbow from a Fantasy Star model.
Major tooling went into her face, hand sculpted with an exacto knife, a lil craft foam, paint and that's all she wrote.

Update: I gave Beta some plastic surgery to smooth out the rough spots!
