>>106843425The sub-villain from the comics who was also transported from Earth and so aged up and down just like Amethyst. He later came to Earth and was in her school to spy on her while Opal rebuilt his strength.
I imagine in the Bri-Amethyst version he is a jerk in her school, with ambiguity over whether he is a villain in Gem-World or he has a reflection or he can swap over like Amethyst.
Lots of shipping potential, particularly as Amethyst doesn’t like him and fans eat that up.
