Roza is a 28 year old swellow living anywhere (as of this image, currently in the sonic world). She travels with a vulpix (kiran). She has the powers of a swellow. She can use items and the common sonic techniques. She's not one for flashiness, she prefers the showing of skill. She could use extreme gear but she has a preference for speed type machines.

How she's grinding on a guard rail of eggman expo is unknown (she is following behind kiran...they did not go into the chemical plant tube).
