OK, this requires background on my story, and a lot of spoilers if you're one of the 10 people who read it.
One of the main antagonists is a group of beings based on precious stones (you might see where I'm going with this),
who take people with unique powers and encase them in crystal, locking them in a dream state while an artifical being with their face and ability is created, called Dolls.
Each is named after the stone they share a colour with (Amethyst, Ruby, Topaz, Sapphire, Emerald and their matriarch, Diamond), can regenerate from any damage and each controls an aspect of time or space.
The thesis of the story is broadly about overcoming limits (personal, societal or physical, depending on the character) and the Dolls represent the dangerous idea of perfection.
They see themselves as perfect, complete beings who don't need to improve because they are the ultimate lifeforms. Ageless, incredibly powerful and in their own eyes flawlessly beautiful.
The main character who's arc intertwines with the Dolls is lured with the promise of perfection; she sees herself as weak and plain, constantly berating herself for her perceived weakness. Until she finally accepts herself as being good enough and vows to free the people the Dolls have captive.
That leads me to Stephen Universe; I haven't seen the show but from what I understand its about coloured characters based on precious gems who can regenerate from damage. On hearing that I started to worry that it sounded a lot like the characters I was writing.
And I want to know if my concept is distractingly similar, or if most people wouldn't notice, or do i just not know enough about the gem people in Stephen Universe to see that they aren't even similar?
