So, being KG, it has to be a two-element combination then.

Then we have free Earth + Lighting combination just for Steel Realase ;) This.

I really just wish Kishi would reveal all advanced natures. Even if it contradicts with everything we thought. Maybe in Zen no Sho, which I expect to be a databook covering the entire series.
