Side B - Buster Cannon
Future Trunks draws his hands back down to his sides and charges two blue energy spheres in his hands, then he combines them together in front of him to fire the energy wave at the opponent. This attack has limited range, and decreases in power as it gains distance.
Up B - Afterimage

Down B - Finish Buster

This did constant damage with low knockback to any opponents. You won't release the energy sphere when the B button and aimed up, down, or straight, depending on where the control stick is tilted (if you do this move is midair, you will stop for a brief moment until you release it).
Final Smash - Shining Sword Attack
Future Trunks fired a Burning Attack out of nowhere. Of the opponents is catch of the attack, they will be stunned and Future Trunks flies up. comes down to vertically slash the opponent with his sword. Next, he slashes the opponent multiple times, chopping them up into bits. Finally, Future Trunks draws his hand back and brings it forward to fire a yellow energy wave at what's left of the opponent.

Future Trunks is the Saiyan and Human hybrid son of Vegeta and Bulma from the alternate future. By the time Present Trunks was born, the timeline had been altered by Future Trunks' and Cell's trips to the past. Therefore, the two Trunks had completely different lives (as opposed to those who lived before the Time Machines arrived, they lived exactly the same lives as their counterparts until the point at which the two timelines diverge: three years before the androids arrived).
