What is a metamorphasos like nymphadora in Harry Potter?

Answer 1

A Metamorphmagus (pl. Metamorphmagi) is a witch or wizard with the ability to change his or her physical appearance at will, rather than requiring Polyjuice Potion or a spell like the rest of the wizarding population. They are extremely rare.

Unlike Animagi, Metamorphmagi can take a wide variety of forms, changing gender, race, and age, potentially looking like anyone at all, or even just changing a part of their appearances, such as the shape of their noses.[1] Animagi also transform at will, but only into one animal form which is determined by their inner traits. It is never revealed if Metamorphmagi can take the full form of an animal, however it is highly unlikely as its compared to polyjuice potion and specifically describes outward appearance changes.

Also, a Metamorphmagus is born, not made; it is not a skill that can be learned.[1] There also seems to be a degree of heritability, as both Nymphadora Tonks and her son, Teddy Lupin, were Metamorphmagi. The ability presents very early in life, as Teddy Lupin's hair changed colour when he was a newborn infant, as did his mother's.[
