Gem body that is holded together by liquid gold like phosphophyllite from land of the lustrous, for 5 times can mutate and modify their body if they consume enough gems for it.
1st midas curse but right hand turns crystal left hand turns gold
2nd full control over gems and gold around them
3rd super strength and durability
4th can mix gold and crystals(now they look like a human before this they looked like just before phosphophyllite become full human-god)
5th become a dragon
1st and 2nd are right the moment they come in to the world 3rd next week 4th around a mouth (after this they have gender and emotions)5th???
??? Stole bunch of diamonds and was going to transfer them to Europe by hiding them in gold bars the company he works for transfer gold between countrys and very shadie he wanted to quit and never associated by this companym turns out this company is criminal enterprise and he got found out they throw him in to the liquid gold he had the diamonds in his pocket with a weird gift from a old homeless stranger as good luck charm after mutations-magial totem they momory erased completely and(after 4th mutation) now only have vague memorys about his word is being a comic that he read before dying to a plain crash
They got born-isekaid in a crystal cave in dc
The rarest ones gives more help towards the mutation goal
Eating crystals they turned doesn't help them meet the criteria they need to mutate so it's useless
After 4th mutation they have hunger like a living being they can eat gold and crystals but regular meal diminish this hunger more (like a real living being but they are not a living being until 5th and final? mutation)
After 5th mutation they lose the midas curse instead they can just summon gold and crystals
