Technically if there is iron in us and earth in iron does that make bloodbending possible with earthbending?
Wrong kind of Iron. The Iron in your Blood isn't the same. Also, it'd be too small for anyone to bend anyway.
My family did make that joke when bending the poison out of Korra's blood. "Oops, there goes all your iron! My bad! Korra?"
Pfffft-
We have iron inside of us?
And well idk my religion belived that human made of dirt
But eh idk
What do you think?
