Yes he is.
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.[
They have one son, Teddy Lupin.
No, they are second cousins. Narcissa Malfoy (Draco's mother) was Tonks' aunt which means that Teddy Lupin is her great niece and so Draco Malfoy's is Teddy Lupin's second cousin.
Remus Lupin and Nymphadora Tonks.
Nymphadora Tonks is Teddy Lupin's mother. She dies months after giving birth during the Battle of Hogwarts.
Teddy Lupin, whose full name is Ted Remus Lupin, is the son of Remus Lupin and Nymphadora Tonks. Teddy is named after Ted Tonks, Nymphadora's father who was murdered by death eaters, and is Harry Potter's godson. Teddy was born in April 1998, and is a metamorphmagus like his mother.
