Interdiction has a very simple design; it is a straight rod of energy that glows red.
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.
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.
