A "genderswap" refers to the almost magical version of a sex change, wherein a character of one sex turns into one of the other sex without any medical involvement. 

This tag can also apply to an image of a character of one sex depicted as one of the opposite sex (e.g. a male version of a female character or vice versa). May also apply to male-to-[[futanari]], but since futanari is not wholly female, female-to-futanari may also qualify. A being with no sex depicted as any of these may technically count.

This tag can also be applied to an [[otoko no ko]] if the character is given female traits such as the presence of actual [[cleavage]] or the obvious absence of a [[bulge]] at the crotch. For [[reverse trap]]s, the absence of cleavage or presence of a bulge applies.

If a character is genderswapped often enough, the genderswapped version may be given its own name. For male-to-female genderswaps, this is often the normal character's name with "ko" appended to it. (子 "Ko" meaning "child" is a common ending for Japanese girls' names.) For female-to-male genderswaps, "o" is sometimes added. 

Known in Internet circles as Rule 63, wherein there is a female or male version of any given male or female character, respectively.

[b]Notes:[/b] 
* If the person has only swapped bodies with another from the opposite sex, but the body itself has not changed, then use [[personality switch]] instead.
* The "女体化" tag may also on occasion be used to describe female [[personification]], rather than a genderswap.
* If a character in canon is genderswapped but rarely shown in their original form (such as [[Mai Natsume]] or [[Tanya Degurechaff]]), the tag only applies if said original form is included or somehow alluded to.
