Interdiction has a very simple design; it is a straight, glowing rod of red energy coming from the palms of the wielder's hands.
When striking a target, it creates a sphere of glowing red lightning, the same color as Interdiction.
Interdiction is a military term, as an action to divert, disrupt, delay, or destroy the enemy's surface military potential before it can be used effectively against friendly forces. The word also means "punishment".
Interdiction's ground combo consists of a single slash from left to right, a double slash from right to left, and the launching of four blades along a vertical arc. A -Combo can be activated after the double slash, to make Xemnas launch the blades along a horizontal arc instead of a vertical one.
The aerial combo consists of a quick spinning slash, a short range double spin slash, and a medium range double spin attack.
