First, while fighting Madame Rouge from the Brotherhood of Evil, Robin slows her down by freezing her and then breaking her into tiny bits. It doesn't last as her body reforms itself and she captures him.
Robin, along with other captured heroes like Speedy and Aqualad, is frozen into a statue and placed on a wall like so many collectable action figures.
