A metamorpgmagus (plural metamorphmagi) is a witch or wizard that can change their apperance at will, rather than requiring a spell or potion like most wizards do. They are extremely rare.
Metamorphmagi versus AnimagiEdit
Unlike Animagi, Metamorphmagi can change any of their appearance including race, hair color, hair length, eye color, shape and species of nose ect. Animagi can only change into the animal that they will change into for the rest of their lives. Animagi have no controll over what animal they turn into when they become Animagi, but it is always the same.
Using metamorphic abilitiesEdit
It is unknown if metamorphmagi recieve any special training for their abilities, or if they just learn from experimentation. However; given their rarity, it is unlikely that any training could be availabile. Like anamangi, they probably are required to register with the ministry for protection of the wizarding race, and for themselves.
Like many other types of magic, the transformation through metamorphmagism is effected by their emotional state. What ever the person may be feeling, can effect what the metamorphmagus can look like at anytime. Depression and guilt are the most common causes of this happening.
In greek, "meta" means "change." "Morph" means "shape." "Magus" means "magic" or "wizard." Hence, , a wizard that can change shape, and the term "metamorphosis" means an animal changing into another animal, such as how a caterpillar changes into a butterfly.
