Death Wave

Death Wave (大地裂斬; lit. "Great/Grand Earth Rending Slash") is a powerful arcing blade-like energy wave technique used by Frieza in his final form.

History
To use it, Frieza puts his middle and index fingers together and charges an energy sphere on the tips. He then swings the energy sphere around, creating a large Death Beam in the form of a giant, razor-sharp energy blade that can slice through anything.

Frieza uses this attack during his battle against Goku on Namek. Frieza is beating Goku around and Goku soon lands on a cliff. Frieza then charges and fires his Death Wave at Goku and it appears that Goku is killed. However, when Goku opens his eyes, it is revealed that Frieza aimed the attack away to carve a fissure going across the entire circumference of the planet.

In the fourth promotional trailer for Dragon Ball Heroes, after interfering with Wings' slaughter of various Toadmen and doing battle with Wings, the Frieza's race Hero Froze uses a Death Wave to attack Lord Slug.
