Atara

She is a purple alien from a distant planet called (Shīreba) who’s world was destroyed due to people misusing powers. She was able to escape to earth on a pod. Her pod appeared in the news but she’s been hiding for years. She’s injured in a cave on an island. People have hunted her before so she’s scared initially but quickly warms up to kindness. She has powers but is too weak to use them.
