In which a Metamorphmagus uses his abiilities to disguise himself and spy on Kim Jongin.

Metamorphmagus. From the words meta, meaning 'change,' and morph, meaning 'shape.'

A Metamorphmagus 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.

Metamorphmagi (pl.) can take a wide variety of forms, changing and age, potentially looking like anyone at all, or even just changing a part of their appearances, such as the shape of their noses.
