Henshin Is an ability in which the the user transforms themselves in preparation for battle. This process has also been called metamorphisis, magical transformation, or a different name depending on the continuity.
The transformation is usualy activated by utilizing some sort of enchanted object such as a pendant, staff, technological device, or familiar spirit. The user focuses their energy on this object, speaks a special phrase or command (optional), and then undergoes a transformation sequence, often involving an intricate transition of normal atire into an elaborate costume, physiological alterations (changing eye color, hair color, hair length, ect) and enhaced abilities in preparation for battle. This technique can also be perfomed in groups if the user is part of a team. Unlike the super transformations in most continuities, henshin rarely drains the users abilities, and does not make them invincible. It also differs from evolution, as it is not permanent. Heshin can also work in rervese to change the user back to their orginal form.
Numerous methods and circumstances for undergoing henshin vary with each continuity, meaning that there could be multiple variations.
