I just got interested to know her because brian Wood is writing her and she also looks interesting.

Does anybody know what her powers are?

Looks almost like Super-Speed, well that's certainly what is sounds like from the Solicits/Previews for #2.

Something about the ball travelling 2 centimetres, whilst she travelled 17 feet.

Her main power is Super-Beauty.
 
Another neat trick she is capable of is switching the color of her skin from snow-white, green, red, to exotic-brown. Not quite sure how she does it? Maybe we'll find out later she's some sort of shape-shifter or color-shifter at the very least. Well, maybe her marketing team just used some Photoshop. Last not least, she seems to be related to the Haitian from the TV series Heroes (bring it back!) as people, when being around her or just watching her on television, forget about their troubles as well as all the crime and wars in the world.  
 
More seriously, I believe, (even Rick James already knew) she's a Super Freak!

Im thinking time stopping and flight. But who knows what'll come up next.

By the sound of it, she'll be getting more as well.

@RedQueen: After re-reading the second issues im pretty sure Brian Wood is doing a comparison between superheroes and sports stars. And Mara is gonna be Superman, or Wonder Woman to be gender appropriate.

That makes so much sense. Trust Wood to do that.
