laios touden (demon king)

A what-if version of Laios Touden as a dungeon lord, from one of Ryoko Kui's extras.

Since he isn't canon, "Demon King Laios" can't be considered spoilers on his own, but in fanarts, he's sometimes paired up with spoiler-y characters. Please add the corresponding tag when that's the case.

Also, consider adding alternate universe.
