Cat's OC. No touch.
Hiddenite was born to be a third wheel. Her childish personality leads her to do silly things, such as mess up romance and ruin conversations. She is emotionally unstable though, so watch out! If she gets angry, she'll use her weapons and powers to harm the gem/person that offended her.
When she applied for a certain group (that decided she was useless), she became dark and a threat. She wouldn't stop trying to crack gems, and even attacked towns and cities.
