Sword Blast (ブレードウェーブ Burēdou Uēbu, lit. "Blade Wave") is a wave of energy channeled through a sword.
The user slashes with his sword, sending a wide wave of ki energy forward, damaging anything caught in the wave.
Video Game Appearances
It is used by Future Trunks in Dragon Ball Z 2: Super Battle (named Blade Wave (ブレードウェーブ)), Dragon Ball Z: The Legacy of Goku II (also called Sword Blast), Dragon Ball Z: Taiketsu, and Super Dragon Ball Z. The Legacy of Goku II in-game description of this technique is: "This attack will make Trunks swing his sword in tandem with a destructive wave of energy". Janemba also uses the technique in Dragon Ball Z: Buu's Fury.
In the Budokai Tenkaichi series, the charged Ki Blast used by Yajirobe, Future Trunks (with Sword), Dabura, Super Janemba, and Tapion is a 3-dimensional version of the Sword Blast. The energy blade fired from the sword is capable of bypassing an opponent's guard. The only defense against this attack is to either evade it or hiding behind a stages terrain (objects or buildings) to keep from getting hit by it.
Future Trunks can use this technique as a charged Ki Blast in Dragon Ball Z: Supersonic Warriors 2 as well, and he has three variations as special attacks and one more as his Ultimate K.O. in his base form,
In Dragon Ball Xenoverse 2, Janemba's Rakshasa's Claw Super Skill can fire up to 5 sword blasts depending on the button input, though they lack the power to cut through dimensional portals and act more like a standard sword blast. Rakshasa's Claw can also be used by the Future Warrior, thus allowing them to fire their own sword blasts by using said skill.
