Nymphadora Tonks and her son, Teddy Lupin are currently the only known Metamorphmagi in the series; it is a very rare ability, possibly hereditary. Tonks is known to change her hair colour and style according to her mood. She even appears as an old woman on occasion. She can also change her nose appearance, as she does when eating with the Weasley family to entertain Ginny and Hermione. Her son, Teddy Lupin, also inherited this trait, as his hair is mentioned repeatedly changing colour.
