At the end of The amazing Crisis on Infinite Earths crossover event, The heroes were enjoying the Flash’s big surprise which was a giant table in the S.T.A.R. Labs building. While everyone was sitting, they heard a wired laughter. Then the scene cut to an opened cage with a nametag of Gleek. But after that there as not been any physical appearance of this so called "Gleek". Dose anyone known when we might actually see him?
