Spider-Phantom is from another dimension and is the most grey area'd of all the Spider-Men. She often puts her own needs above others but can step out of her way when the multiverse is in danger. While her costume looks similar to "Spider-Gwen's" she is very, very different. She is, in fact, a Robin Hood-esk thief (with more emphasis on taking for herself). An anti-hero she is somewhat cocky, a happy-go-lucky sort of kindness that seems fake, daring, cunning, clever, and a hero at heart. (Her world doesn't use common cuss words and often uses "Rats" or "Fats" for curses. She is afraid of clowns). 

We do not have a specific voice for her. Best of luck!
