Capcom is streaming play of newly announced playable character Decapre in Ultra Street Fighter 4 right now.
Like the iconic Cammy (Super Steet Fighter 2) and the lesser known Juni and Juli (Street Fighter Alpha 3), Decapre is one of Bison's "dolls", though she doesn't fight exactly like the dolls that came before her. She's got a teleport and laser knife gloves! Also, she wears a metal mask and quotes Metallica. Edgy!
Here's some history about her from Capcom:
"Making her first brief appearance in a Street Fighter game as a non-playable character in Street Fighter Alpha 3, where she was seen as one of M. Bison’s Dolls, Decapre now joins the fight! Although a partial mask hides a giant burn mark located on this Russian beauty’s face, challengers will be scarred by her quick and elusive scramble moves as well as her psycho power infused attacks, which allow her to share her pain with her opponents. Players can get their claws on Decapre and the rest of the all-star lineup in Ultra Street Fighter IV when the game begins releasing in June 2014."
