'Trixie' (short for 'Vitatrix z-3000').
Her 'brain' is an A.I. chip, currently inside an android shell.
She used to be in Merrik's gun. In her spare time she runs fashion blogs. (If you read merriks comics you can get a feel for her character while she was a gun.)
Don't you dare tell her she is 'just' a robot.
