[Avatar: TLAB/TLoK] What are some unexplored possibilities for the different bending style?

So we've seen the beding styles expand a bit from the 1st season. 

Water: Blood bending, healing, spirit control

Earth: metal bending, lava bending, vibration sight

Fire: lightning, blue fire, fire propelled flying, mr. explody face

Air: unaided flying

What other possibilities of bending do you think could exist in this world?

Metalbending is achieved by bending trace minerals in the metal. That implies that sufficiently high level Earthbenders could bend trace minerals in our bodies, specifically, our bones. That's right. *Bonebending* is possible. 

(And it also sounds like something out of a horrible Avatar porno)
