Transformation

A Transformation is a change in physical form which usually comes with a significant boost in power.

Overview
Transformation is a process when a Mysterious Being morphs into an alternate, more powerful form.

A Human or animal can also undertake a normally irreversible transformation into a Mysterious Being through different means:
 * 1) A human or animal can transform into an Unusual Type monster through their feelings, e.g. because of their obsession for certain things, of through hatred. For example: Crablante transforming due to eating too much crab.
 * 2) An animal can become a monster by consuming the flesh of the Beast King; ordinary crows morphed into monsters.
 * 3) A human can become a monster from injecting or eating a Monster Cell. For example: Choze.
 * 4) Through science a human can transform into a monster. For example: Marugori through Biceps Brachii King.

Some Mysterious Beings have high willpower and possess the ability to transform from monster to human, although in some cases this requires a great deal of training, as seen with the ninjitsu training Gale Wind and Hellfire Flame went through. Only Surprise-Attack Plum, Gale Wind, Hellfire Flame and Haragiri are known to have that power.

Puri-Puri Prisoner refers to his "Angel Style" as a transformation, however it is simply him removing his clothing.
