In the 1990s, some Ravenclaw students, including Robert Hilliard, speculated that Filius Flitwick was part elf because of his stature, although they never asked him about it. In fact, he was part-goblin.
Behind the scenes
- No real part elves have been shown in canon. As such, it is unknown if they actually exist within the Harry Potter universe, though it is likely, as half-goblins do exist and elves are similar (and possibly related) to goblins.
- It is also unknown if they would inherit the special form of elf magic from their non-human ancestor.
- If they do exist, then it is likely interbreeding between humans and erklings or yumboes is possible as well, as both species are described as "elvish" (and thus presumably closely related to normal elves). Moreover, it would also be possible that humans could cross-breed with Red Caps, Leprechauns and Imps, as all three, while not explicitly stated to be related to elves, are markedly similar to them.
- Students confusing Flitwick for a part-elf may have been inspired by J. K. Rowling's earlier comment that she thought the early movies' version of Flitwick "looked like an elf" (and thus far more non-human than she initially intended).
