The Dark

Onyx is The Black Mist which she doesn't know, nor does she know who her parents are as she grew up in an orphanage. She discovered to be superpowered in puberty when she saw dark smoke surrounding her hands and could once accidentally change her eyes to fully black. She hated herself thinking to be a dark entity and to her thoughts she was destined ruin the world as an evil entity. One day she was seen to save Nat from one of the aliens the avengers were fighting by Wanda and thus was asked to join the team by the Avengers keeping her identity secret. A few days later Loki joins the Avengers and senses a very powerful dark force around only to know that it is Onyx Ebony Raven Atramenta and starts to suspect her. Telling about it to Wanda, he doesn't really get much help. So he sets off to find out himself.

Is their something more in The Dark that is the answer to all the questions? Will their paths meet and if yes is there a fear of intersection?
