Transformation

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

Overview
A Human or animal can 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. A human can also become a "half-monster" in this way. For example: Garou.
 * 2) A human or animal can become a monster from injecting or eating the uncooked cells of a monster. For example: Choze after eating a Monster Cell.
 * 3) Through science a human can transform into a monster. For example: Marugori through Biceps Brachii King.

Several Mysterious Beings possess the ability to transform; morphing into an alternate, more powerful form.

Some Mysterious Beings have high willpower and possess the ability to transform back and forth between monster and 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 this ability.
