Beta


 * Beta is an Autobot from the time of the great slave revolt.



The gravelly-voiced 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 robot rebellion that freed Cybertron from its Quintesson masters.

Cartoon/MUX canon
The night before the climactic battle with the Quintessons, Beta found that A3's Coda Remote still wasn't working. With the remote's ability to override the Dark Guardians necessary for a slave victory, Beta worried the device would be finished in time to strike.

When the moment arrived, Beta led the revolt herself. She held off the Dark Guardians until A3 returned, much to Beta's bear-hugging joy, and saved the day. Beta's continued to fight alongside A3 until Cybertron was free from the Quintessons' control.

Trivia

 * Since Beta is from the time before the invention of transformation, she is technically not a Transformer.
