Yup, pretty much. Though some animals can bend the elements too. Earthbending was actually invented by the badger-moles, and airbending by the flying bisons. And yeah, Wan's a firebender, too, though he doesn't come from our time. He's from way in the past, I'm told.

[Yes, he knows it's not a real type of bending, Ash. Let him have this.]

The best there is!

[The best he's ever met, at least. The only one he's ever met that also threw boomerangs is his father.]
