In "Inside Job", Cop-Tur appears to insult Crasher by telling her that she needs a map to find her brain and calling her "brick breath". After Cop-Tur flees, he turns out to actually have been Scooter disguising himself with a hologram, who then laughs and states that he hopes he didn't offend Crasher.
After Crasher gets beaten in "Quest for New Earth", Cy-Kill ends up having to carry her back to the Renegades' ship.
