I like the concept.
Simple, yet usually makes a great story.
Also, I thought of a cool story that I kind of can't put in my lore but someone else probably can
Basically, the whole idea is that in an alternate timeline, sentient versions of the elements of the periodic table are all fighting and need to work together to build the universe.
The main character is Carbon, who's trying to convince the other elements to allow life to exist in this universe, and is working alongside Silicon to make it happen.
The villains are Uranium, Plutonium, Polonium, Mercury, Arsenic, Radon, Francium and Lead.
They can fuse with each other and make alloys, and whilst elements on their own already have superpowers similar/based on their real life abilities, when fused, they can gain and lose abilities, and even sometimes have whole new personalities.
Like for instance, 2 twist villains, Sodium and Chlorine, are twist villains because they tend to be fused, creating Salt, a very friendly gentle giant.
Carbon has 2 main abilities, the ability to create life, and when stressed, he enters "Diamond Mode", which makes him very powerful.
