This technique is one of the many variations of Henge created by a clan of beastmasters. It allows the user to take on the form of any Humanoid, Monstrous Humanoid, Magical Beast, Animal or Outsider creature the user has seen or has extensive knowledge of. The new form cannot have more than 10 hit dice, and must be within one size category of the user.

In the new form, the user loses all his extraordinary, supernatural and spell-like abilities, templates and other (except Moujuu Aishou), and gains his new form's extraordinary abilities, Strength, Dexterity and Constitution scores as well as all its natural attacks. He keeps his own mental ability scores, levels, hit points, allegiance, base attack, defense bonuses, and save bonuses, but they are adjusted accordingly as per his new size category and ability scores (if any change occurred).

The user can use technique normally if the target has the necessary body parts (ie, hands and fingers for hand seals, opposable thumbs for techniques requiring weapons) but all his equipment merges with that of his new form. Any property of his new form, such as resistance to cold weather, will be carried over to the user. If the new form is capable of speech, the user will be able to communicate normally.

During the technique, the user acquires all the physical qualities of his new form without losing his mind to it. Physical qualities may include natural size, mundane movement capabilities (such as burrowing, climbing, walking, swimming, and flight with wings, to a maximum speed of 120 feet for flying or 60 feet for nonflying movement), natural armor bonus, natural weapons (such as claws, bite, and so on), racial skill bonuses, racial bonus feats, and any gross physical qualities (presence or absence of wings, number of extremities, and so forth). A body with extra limbs does not allow the user to make more
attacks (or more advantageous two-weapon attacks) than normal.

Furthermore, the user's Chakra Signature and Scent also changes to imitate one similar (but not the same as) to the new form. Templates, while normally inaccessible, are still present (for example, a cursed seal can still be taken advantage of by the origin) as are seal slot presently occupied on the user's body.

Unlike standard Henge, the user's new form cannot be discerned from the real thing.
