Captain Cold

Bio
In 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 always stops him. The other Titans become angered at him freezing their leader and defeat the villain. Later on, Robin has a terrible cold because of this.
