Dragon Ball Xenoverse Screenshots

Some full shots of the mysterious fighter as well as a version of Trunks only seen in Dragon Ball Online, as well as showing that whomever red-hair is he will feature prominently.

Namco Bandai had this to say:

In Dragon Ball: Xenoverse, the mysterious fighter will be allowed to blast his way into multiple famous battles from Dragon Ball’s illustrious history! Thanks this, gamers will be presented with an unpredictable ‘DRAGON BALL’ experience; perhaps rewriting DRAGON BALL history as we know it! 

Whether this means the fights will not be confined to the Z series or not we have yet to see. So far the screenshots suggest some future time period not seen in the anime, as well as the Saiyan Saga through the Frieza Saga to the Cell Saga.

They promise more news and teases in the weeks and months ahead, and we'll be reporting them.
