A single strike from it can disperse an entire rainstorm and slice off the top of a mansion. Isshin's use of Getsuga Tenshō against Aizen in his Second Fusion form demolished a large radius of the Fake Karakura Town, left behind a huge crater, and was powerful enough to create a large gash in Aizen's head, prompting Aizen to call it a ' splendid strike.' Īfter Ichigo regains his Shinigami powers for the second time, his Getsuga Tenshō is noticeably larger and more powerful in its Shikai form than it was before he lost his powers. Ichigo has used this technique in several different manners, such as striking the ground to create an omnidirectional blast to knock away incoming attacks or slashing at the ground to upturn it and crush everything in its path. The Getsuga Tenshō is a powerful technique with great force, creating large-scale damage and destruction. As stated by Zangetsu, knowing the name of an attack heightens its power compared to its strength when the wielder does not know its name. Ichigo uses this ability without knowing its name several times, but later masters the technique during his Bankai training. This slash takes the shape of a crescent moon or wave.
At the instant of the slash, the Zanpakutō absorbs and condenses the user's Reiatsu before releasing it at the tip of the blade, magnifying the slash attack, which flies forward.
