For every given male character, there is a female version of that character.

Its converse tends to be lumped in with it:

For every given female character, there is a male version of that character. (But do keep in mind the First Law Of Gender Bending generally means there are fewer male versions of female characters.)

The point of this rule is that most of them aren't canonical. The internet has a fascination for producing gender swapping regardless of the context of the original character. No character is immune to this effect — not Darth Vader, not Master Chief, not Jesus — no one. (Not even Chuck Norris. Rule 61 lied to you.)

When a separate character is a female knock-off of an existing male character, you have a Distaff Counterpart; if it's male, then you have a Spear Counterpart. Crossdressers, of course, provide their own version of this.

Note that though this can be a Porn Trope, a great many examples have nothing to do with porn.

  • Danielle is a female version of Danny Phantom.
  • Metalocalypse. Dethklok had a tribute band that was composed of all women, giving each of the band members a female counterpart. Dethklok rejected them, as they found them rather creepy.
  • Superjail! has an episode where female versions of the entire cast appear, complete with a female-to-male transgender to compliment Alice and a lesbian couple in the place of the gay couple in SJ.
  • Happy Tree Friends will prove this rule disturbingly true for Flippy with a simple deviantART search. Although, use caution with that one, because it's not a female version of Flippy they're making, it's their own characters and a separate entity that's basically just if they made Flippy as a girl and then ship them with the real Flippy.
  • The Adventure Time blog has recently given a lot of attention to a series of Rule 63 drawings by one of the concept artists. An upcoming episode will use this concept.


  • Every Vocaloid (including Rin and Len) and almost every UTAUloid tend to have a genderbend. In the UTAUloid's cases, many are made by the authors themselves. People have also edited their vocal files to create a masculine/feminine version of the characters.
  • Among Mixed Martial Arts fandom, Cristiane "Cris Cyborg" Santos is considered to be Wanderlei Silva's female counterpart.
