Idea inspired by a tale, I think appears in Arabian Nights, 1,001 tales by Sherazade. The one about the demon beauty contest, where two demons decide they want to hold a contest of beauty using humans. They each decide to pick a fetching human, and let the other’s human judge their beauty by the reaction they have to each other.
In the Voltron universe, the demons chose Lotor and Allura for their game. Naturally somehow the two end up hooking up romantically after the contest. XD
A silly little idea I penned back in 2002.
