Little Black Dress

Some fans do not ship a particular pairing, but instead prefer to read/write about a single character. These fans will read anything including their favorite, no matter whom he/she is paired with.

This character is often referred to as a little black dress (or LBD) because he/she goes with everything (literally in some cases).

The PPC has its own LBD character in the form of Agent Luxury.

Notable LBDs

 * Buffy the Vampire Slayer has Spike, who, even in canon, has been paired with several regular characters.
 * Transformers has the character Starscream (who has appeared in some VERY weird pairings).
 * Harry Potter has... well, nearly every main character appears to be an LBD in fanon. Professor Snape and Sirius Black seem to get the LBD treatment a lot.
 * Who can forget Captain Jack Harkness from Doctor Who?
 * Tails from the Sonic universe is also a good candidate. Even though he's eight years old.
