- Alternative Character Interpretation: Tabletop Games fans on 4chan once got their hands on this comics and decided that it's a disfunctional Dungeons & Dragons game, Horsewoman is a GMPC, Etrigan and Xanadu are played by a pair of munchkins, Exoristos by macho guy or girl who shouts movie quotes all the time, Al Jabr by only normal player in the group, Yustin by Dungeon Master's Girlfriend and Vandal Savage by Mr. Welch.
- Eventually, Al Jabr is a Non-Player Character.
- Crazy Awesome: Vandal Savage.
- The Firefly Effect: Many fans have expressed concern that, since this isn't a superhero comic (at least not in the traditional sense), it may not last very long. That feeling was ultimately justified, as DC cancelled it with issue 23 being its final issue.
- Iron Woobie: Most of them are pretty sympathetic but the biggest ones are Jason and Shining Knight.
- Memetic Mutation: "WELCOME, TASTY RARE CREATURES!"
- No Yay: Cain and Ystin. Sweetest I ever tasted, indeed.
YMMV / Demon Knights
