Judgement of Nergal

When this jutsu is used, everything about the victim, their personalities, history are assimilated and compacted into the users mind. In essence this is a black hole sucking in all light, but in the sense a blackhole within the mind taking in all of the victim in him, therefore basically absorbing the victim into him and becoming one being. As a result of this, they are able to have access to some jutsus of the previous victim as well as personality. When they transform to look like the previous victim it is flawless, because in essence they are one being. Gaoh uses gravity to make forbidden fuuinjutsu happen. The victim of this technique is fated to live in limbo for eternity or until the user chooses to release you. This jutsu is very dangerous and once done you will need to have months and months of rest time.
