For a new front I'm to be hired, a status badge for your attire, what am I?

I can multiply the power of the sun Kids have used me to torment tiny bugs I am an important tool of a detective A common icon for zoom that is most effective

Eyes like a serpent, bones cold and white, or not. I have many faces but no two are the same.

I don't exist but most know me. I'm crystalline if you show me. I kill steel men of other worlds but will not harm you. Originally green, now I'm other colors too. Batman has a sample as a last resort. What is this rare stuff that cannot be bought?

I can be a circle or half circle, clear or not, I will help you achieve an inclination, all from a dot.
