masked saiyan

First appearing in Dragon Ball Online before being re-implemented in Dragon Ball Heroes and Dragon Ball Xenoverse, the Masked Saiyan is a brainwashed Bardock, adorned with a white mask with the symbol of the Time Breakers (who consist of Towa and Mira) on its forehead, and also covering the eyes in black, whilst also wearing a completely different set of armor.

In the Heroes series, after being freed of the mask's brainwashing, he ends up becoming an affiliate of the Time Patrol, as Bardock: Xeno.
