Year One

While desperately searching for his kidnapped wife, Superman is confronted by Doomsday while inside the submarine the Joker and Harley Quinn stole. The Man of Steel, fearing for his wife and unborn child's lives, tackled the monster into the upper atmosphere but is horrified when he realizes he was drugged by kryptonite laced Fear Toxin, and 'Doomsday' was really Lois Lane.

Year Three

The hallucination of Doomsday is seen again during Superman's dream state, only with the Man of Steel saving Lois's life this time instead.
