The Bad Guy Wins: Fan Fic
- The Masks We Wear seem to be heading this way, though unlike in canon the Fire Nation doesn't seem to have any intention of actually burning the continent down.
- Lex Luthor grants Lois Lane an interview in Lex Luthor Triumphant 8 months after Superman vanished without a trace. We're told in 12 agonizing chapters how Superman is being dissected for science and profit, how his Fortress of Solitud is breached and seized, how Batman miscalculated Luthor's genius, how Wonder Woman and the JLA are duped into fatal scenarios and how, at the end, Lex Luthor ushers humanity into a golden age thanks to all the magic and science he took from the heroes.
- The Pony POV Series has the Alternate Universe "Epilogue", which shows what would have happened had Discord succeeded in defeating the Mane Six. To say that it's a Crapsack World would a vast understatement. It's explored in more detail during the Dark World Arc of Season 6.
- In Game Theory (Fan Fic), although this isn't actually a bad thing, due to the nature of the story. Precia succeeds in reviving Alicia and dupes the TSAB into believing she is dead.
- Michio Yuki has succeeded in letting Ran Mouri find out Conan Edogawa's true identity: Shinichi Kudo in The Devil and the Detective.

- "Character Championship Wrestling": In the Massive Multiplayer Crossover wrestling promotion, heels have won their fair share of rivalries. The biggest examples are Ben & Gwen Tennyson, who are The CCW Magnus Champion and CCW Female's Champion respectively. The former, after losing his Title to Autolycus, stole his Title Belt that night and then ran him over with his car the next week...all setting up for him to win it all back at the next Pay-Per-View. The latter traded The Female's Belt back and forth with Emmy, and then challenged her to an all in I Quit Match where if Emmy lost, her reigns would be erased and everything would be counted as one Gwen reign. Emmy would accept...and then get subsequently screwed by a random run-in from Zoe Payne and then get her face repeatedly curb-stomped into thumbtacks by Gwen. In a very solemn moment, Emmy uttered "I Quit", and Gwen, through all her terrible actions and bad attitude, was able to walk away with The Belt while a poor girl was sent to the hospital for three months. And to this day Gwen still has The Belt...
- The Axis Powers Hetalia fic Human Curiosity largely takes place about a hundred years after the villains win. The secretive HCS kidnapped most of the Nations, subjecting them over time in increasingly atrocious experiments. Many of the remaining Nations had given them up for dead.

Even though its leader was killed, he won in spirit.

- My Little Avengers; although Loki dies at the end, he notes that his death will release a wave of magical energy that will mutate every living thing in the world within a few generations, creating the world ruled by magic that he always wanted.
