Kor'ui Airi, Air-cast Pilot of the T'au Empire, was exposed to a unique radiation called Pneuma that permanently transformed her into an inflatable version of herself. Her cyan-colored skin is silky and rubbery like latex, incredibly elastic. Her body is inflatable, full of silky air, evenly expanded in her bust, butt and thighs to a hourglass figure that won't fit in armor. Thus she can only wear a stretchy black leotard. She tends to inflate with helium that causes her to float buoyantly.
