Hidden body release allows the user to sprout arms, eyes or any other body part out of their body, thus allowing for a whole ring of kekkai genkai jutsu's

Hidden Body Clone: allows the user to produce a fully functioning self thinking self preserving clone that has only the abilities of it maker during the cloning, the 2 may learn abilities seperate from eachother and may go as far apart from eachother, an example is gereiz and his hidden body clones, no one knows which one is the original or if the orginal is even alive anymore, there are 10 known clones, and their may be more roaming around

Kekkai Genkai Theiving: if the hidden body member kills another person with a dojutsu or other kekkai genkai they themselves can steal the technique from the person, it is fabled that the original Gereiz had stolen the sharringan, the shikotsumiyaku, the byakugan, and the boil releases

Hidden Body Cage: requires 2 hidden body clones or yourself and a clone. the 2 extend themselves to surrond their victim in a cage allowing them to strike at the victim inside at any angle and to strike at anything outside trying to save whatever is in their, an example is when gereiz was fighting a group of hidden mist ninja's he had sent out 2 clones to capture the leader while the 2 clones fought the leader who was trapped inside, the one free gereiz fought the other five using his hidden body and waldes abilities

Hidden Body Weapon Storage: the user can use a hand to take a weapon and hold it within him or herself, or to hold simple weapons in an area where they can pop them out into their hands, an example of this is when Gereiz was training and a ninja decided to surprise attack him since he looked disarmed a dagger attached to a chain came from his forearm to a parry the incoming shurikens

their are more things than can be done with the hidden Body release these are just some exapmples
