Kat is the main protagonist of the Gravity Rush series. Having started out as a lost girl with no memory, Kat quickly embraces a superhero role within the city of Hekseville as a shifter. Her adventures eventually take her to the ends of the world, where she is allowed glimpses of her clouded past.
The details of Kat's origins are unknown as she is suffering from amnesia and has yet to regain her full memory. However, it is evident that she was an inhabitant of a city at the top of the world pillar prior to falling to Hekseville . It is also probable that Kat was a figure of great power - possibly a queen as implied by Cyanea 's dream in Boutoume.
