Shining Sword Attack

Shining Sword Attack (シャイニングソードアタック) is a rush attack used by Future Trunks. Future Trunks flies up and 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, inflicting a high amount of damage.

History
Future Trunks used this attack in his Super Saiyan form during his battle against Mecha Frieza. Believing that Future Trunks was killed by his Supernova, Mecha Frieza and his father King Cold became distracted long enough when Future Trunks fired a Burning Attack out of nowhere. However, Mecha Frieza jumped in the air to dodge the attack, though while he was stunned, Future Trunks attacked him with the Shining Sword Attack, putting an end to the cybernetic evil tyrant. The first slash is named High Strike in the Dragon Ball Z Collectible Card Game.

Later, Goku landed on Earth, and to make sure he was Goku, Trunks tried to do this attack on Goku as well, but Goku blocked every Rapid Sword Stream slash Trunks made with only his index finger, to which Trunks responded: Those were the same moves that killed Frieza!

Future Trunks also attempted to perform the Shining Sword Attack in his base form against Android 14 in the movie Dragon Ball Z: Super Android 13!, but the first vertical sword slash was blocked by the Android, who then punched Trunks away before launching the sword back at him.
