Just for you to know what we know as "steel" is not composed of 100% steel.

Of course it is. Just like a human is composed of 100% human. Or a sausage is 100% sausage. Steel, however, is not 100% iron. Steel, as such, is not an element but a compound of iron and an amount of carbon falling within a specific range. If you add yet another element(s) to the mix, you get varieties of steel, like stainless steel (if you add Chromium), etc.

For some reasons, I believe that the third brother will have electricity user ninja. I mean, if the first one is a water user and the second one a magnetic, why not the third brother be electricity.

I hope not... Didn't we already have one such dude? Raiga, or whatever was his name, in the curry of death arc.
