Next February, a new Dragon Ball title will be shooting beams in to arcades across Japan. The game is called Dragon Ball Zenkai Battle Royale.
It's a four player networked game that seems similar to Dragon Ball Z: Tenkaichi Tag Team.
In Dragon Ball, Zenkai, as the Dragon Ball Wiki explains, is a genetic ability that only Saiyans have that enables them to increase their power significantly after getting hurt.
