An accident with an experimental diamond mining machine, the Gemkat 6000, somehow turns brutal convict Rex Shard, into a crystalline giant whose touch turns people and objects to crystal. And that's only the beginning of his new powers. Seeking revenge for his accident, Shard first sets his sights on getting Warden Cyrus Meece, whose greedy exploitation of his prisoners led to the ordeal in the first place, and the Gemkat 6000's inventor, Dr. Greenbox, all the while randomly ""crystallizing"" every location he comes across. Can the SWAT Kats find a way to reverse Shard's condition before it's too late?
