So when i see fire benders use lightning bending I ask why did lightning bending is for fire why can’t it be air bending that controls it to make storms and stuff pls tell me in comments
I think lightning generation should have been a separate element, with it’s own nation and people, I think that would have been cool, that would mean an extra season for ATLA which would be lightning, if that was the case lightning would most likely be book 3 and fire book 4.
Oh and the answer to your question, I’m my opinion, no, air benders should not learn lightning generation, I don’t exactly agree with fire benders having the ability either, like I said before, lightning should be a separate element.
Avatar is based on the philosophical elements that we have known for centuries. So when it came to lightning, they made it a part of fire bending because fire is an outburst of energy and lightning is practically energy. Hopes this answers your question.
While I understand the idea of centering it on what are typically known as the four "Aristotelian" elements, I do feel like electric bending would've been a really cool culture. However, I do like it as a specialization of firebending.
