Captain Cold (Leonard Snart) is a minor villain in Teen Titans Go! comics.
In the comic "Cold Blooded," the Teen Titans arrive to fight Captain Cold. The villain is able to successfully freeze Robin in ice. Everyone, including him, is astonished, because the villain admits he's never been able to freeze somebody, because the Flash and Kid Flash always stops him. The other Titans become angered at him freezing their leader and defeating the villain. Later on, due to being frozen in the ice, Robin catches a cold.
