Random Teen Titan

This one's up for discussion. What should her name be and what are her abilities?

[EDIT]
I'll be posting the full-fledged bios here:

~ Bio by: ~ARC-1138 ~
Name: Alice Smithson
Superhero Name: Half Moon
Height: 5 feet, 6 inches
Blood Type: AB Positive
Powers: Umbrakinesis, Photokinesis

History: Alice was sort of a strange child. She'd act so strangely during the lunar cycle that most of the kids called her the "Moon Chlid". She was at her kindest, most beautiful during the full moon. Conversely, during the new moon, she was a dark, heartless girl. Her parents thought that she was manic bipolar. Some of the kids thought that she was just crazy.

The truth is, Alice is a shell for the souls of two entities, named Shas'on and Fortuna, mirror spirits of light and darkness. The two entities were banished into the girl's body while her father, a famed holy warrior, was alive.

The spirits somewhat take turns influencing this poor girl, with Shas'on, the Lightbringer, taking more prominence during the full moon and Fortuna, the Shadow, taking more prominence during the new moon.
