Kiki has something similar to what some call a Stand in the form of a bat creature she calls "Big Hat" (or "Fat Bat" when she's rather snippy). Using him, she is able to alter her body as well as nigh-omniobservant of anything within 30 feet of her. However, as a truck driver she has little interest in using these for personal gain... or for anything, really. But Big Hat can sometimes goad her into doing things.
