Zoe is a gem hybrid like Steven universe. Here's her story on how she became a crystal gem.

it was a normal day for Zoe she was walking down the normal street that she went down every day to walk home from school. Then there was a large boom that she heard up the street at the elementary school. Oh no I better help them. When she got there she saw three strange looking women. One had a Afro and was tall. One was short and was purple. The last one was tall and skinny and had a nose like a bird. I pull out my sword from my gem stone which was a purple garnet. So after a long battle that I did most of the hard work. They come over to me and the one with the Afro knocks me out. Find out what happens next time in part two. Please comment. No mean comments those ok I'm sick of the mean comments.
