In a new magazine scan of V-Jump, Dragon Ball Xenoverse was featured showing both Future Trunks and the mysterious red-headed warrior. While the warrior remains unnamed, his intentions are hinted at as well as a possible connection to Future Trunks.
His exact purpose is not detailed, but the mysterious warrior will travel throughout time using "The Time Storage Vault" to become involved in various battles. Each time he does, the timeline is altered. Future Trunks seems to have noticed the activity of the red-headed fighter, but how much he knows and if he's going to stop him is not stated.
A release date has still not been given, but Dragon Ball Xenoverse will release on the PS4, Xbox One, PS3, and Xbox 360.
