The attack is first seen in Dragon Ball Z when Future Trunks returns to his timeline to destroy Future Cell in his imperfect form.
Dragon Ball FighterZ is a 3-vs-3 team battle fighting game in development by Arc System Works, the same developer as the acclaimed Guilty Gear fighting game franchise.
Dragon Ball FighterZ delivers an explosive, action-packed game that combines classic 2D fighting with advanced 3D character models that look and feel as if they are straight out of the Dragon Ball series.
The attack Future Trunks is most likely ready to use is Heat Dome in which Future Trunks throws his opponent up in the air and points both his hands up toward them.
