Anti-Monitor

Anti-Monitor, the gigantic, matter-destroying robotic being from the Antimatter universe, is perhaps more befitting for the big screen, but considering his history with Supergirl, SOME tribute to him should be payed on the CBS show. Anti-Monitor is responsible for the original Crisis On Infinite Earths, and the death of Supergirl. He may be a bit too outlandish for a television series, but if The Flash can pull of Gorilla Grodd, anything is possible. Perhaps they can use Anti-Monitor in the same way Smallville utilized Darkseid in its final season, with a less-is-more, mostly offscreen approach?
