Killer Frost and Deathstorm had been portrayed as some pretty powerful bad guys during Welcome to Earth-2s runtime, and the final moments some them lay an absolute beat down on The Flash. In a shocking move, the pair, along with Reverb, got the better of the Scarlet Speedster and proceeded to put a truly brutal beating on him, literally beating him to death until theyre stopped. And who is it that stops them? Why, thatd be Zoom. Not happy that his prize asset has had such damage done to him, Zoom proceeds to kill Deathstorm and Reverb before also making his wrath known to Killer Frost, although she's okay for now as she was the one trying to stop the Scarlet Speedster from being completely wiped out.
