My Batman – The Devastator
Out of all the Dark Knights, I sympathize with the Devastator the most. He’s the Bruce Wayne who let down his guard ans trusted his best friend Superman. Unfortunately for him, something happened to the Man of Steel and he just turned evil, destroying cities and killing members of the Justice League.
With his back on the wall, the Batman of Earth -1 used the Doomsday virus on himself just to kill Superman.
