TG (short for Transgender, but implicitly, Transformed Gender) refers to pictures, usually fanart, depicting a character of one sex/gender as another. Many TG works are non-sexual in nature and done for creativity or simple humorous purposes. Since this is especially true with characters displaying heavily stereotypical manners for their gender, TG art is predominantly of males. Most artists tend to choose a famous character who will still be recognizable to the audience, modifying their traditional costume only as much as needed. Some online communities, such as 4chan, refer to it as "Rule 63" or "Rule 75" (especially when the image contains nudity).
