Elseworlds: Old Man Superman (or: Kamandi: At Earth's End)
In the '90s, DC released a bunch of alternate-reality Elseworlds specials, which asked the question "What if... DC stole this idea from Marvel?" The answer was that you get some good stories, some bad stories, and some stories that were just WTF. Superman's first ever Elseworlds appearance fell squarely in the last category. For starters, it wasn't even a Superman comic. It was about Kamandi, the character Jack Kirby created in the '70s after watching Planet of the Apes too many times. Superman doesn't even show up until the last two issues, and he looks like a frightening bodybuilding hobo.
This story replaces Kamandi's usual "talking animal world" setting with more of a Mad Max situation, and also gives him a leather jacket and giant guns, because '90s. This version of Kamandi was raised by a computer he calls "Mother" in a hi-tech bunker under a post-apocalyptic world. One day, Mother asks Kamandi to go out and murder some guy she claims caused the end of the world, somehow. After fighting deformed mutants and crazy bikers and such for four issues, Kamandi finds his target, who turns out to be a much older, musclier, and beardier Superman. Also, he's amnesiac and seems to be taking a dump on the ground the first time we see him.
