>Red Metal used to be a mere rank and file metal, nobody knows which, but a rank and file one none the less
>Essentially, he was a nobody, a person with nothing to them
>During the war started by Adamantine against the Gems, he was mortally wounded during a gem attack on a metal base
>While he's slowly dying, he realizes that, like all other metals, that if he dies at that point, he as he knows himself is gone, and only a new version of himself will be born
>In that moment, his desire to live consumed him, and he forced himself upon another consumed metal
>Both of those metals died that day. They were no more. But that one metal's desire to live pushed through, and asserted the mind of the original Red onwards.
>Now, after thousands of years, he's a force with all the powers of the metals he's consumed to become stronger, being able to use all their weapons whenever he wants to and being terrifyingly smart
Also for some reason I imagine Red looks like a clown to some degree, to make him similar (and a bit different) to Spinel.
Basically, I imagine he's Joker+Diavolo+Starscream to some degree.
