Hadan

Hadan (破断, Rupture) is an ability known only to beings of the Underworld, most noteable Gozou Enma. It is, as stated by Enma himself, an art of destruction and chaos. It has many uses, as it is more of a category of abilities rather than a single one. Since this ability is mostly unknown, it is not known how it works or how to learn it.

Uses:
Shockwave Type: This type literally cracks the air itself with a simple punch, and sends a powerful shockwave outwards, demolishing anything in its path. Can also be used by clapping ones hands.

Bubble Type: The Bubble type creates a bubble of energy around the users fist, and enables him/her to use an explosion-like attack, capable of crushing stone and making dents in metal. Although the uses of this ability have varied (between using it to heighten ones punching power, or crushing things one grabs), the appearence and strength is the same.

Beam Type: This type releases a blue lightning-like beam from the user (usually the mouth, palm or fingers), which is capable of creating three different effects when shot; it can pierce it's target to make concentrated damage, or explode on impact for more wide-range damage. And third, it can simply "smash" its opponent for weak damage (usually used to knock a weaker opponent unconscious).

Yukan'na Hadan (Gallant Rupture or sometimes referred to as Brave Break): Gonzou Enma's speciality. It differs greatly from the other variants, in which the user (by grabbing ones opponent) can turn his enemy into stone which then crumbles to small pieces and dust. It is performed by Gonzou pouring over his Reiatsu into his opponent and then turns them to dust due to an unknown fact. The creature then shatters by the large pressure the Reiatsu. The clothes and some equipment of the victim also turns to stone, but some does not, e.g. the Shinigami's Zanpakuto. The ability is based upon the ability of Medusa, a monster in the Greek Mythology who could turn her enemies to stone with her eyes.
