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).
Some artists consider it a cheat to draw TG art of certain characters who have canonical androgynous overtones to them. Guilty Gear's Bridget is very rarely drawn as explicitly female, while characters like Final Fight 's newhalfs Poison and Roxy tend to be more popular in futanari art.
- For anime fans, Ranma ½ popularized the idea of a magically induced transformation with little or no other associated physical issues, and were common avatars in fandom.
- Demitri Maximoff of Capcom's Darkstalkers series popularized TG art of video game characters (especially from fighting games) which in this case is often called MB. This refers to an in-game special move of his called Midnight Bliss, wherein the opponent is turned either into a woman (if male) or into a more stereotypical woman (if female). Thus since 'official' TG versions of several characters exist, fanart typically speculates and extends this idea to other characters.
- Final Fantasy VII may also have contributed to TG in video game fanart, as Cloud Strife (who once had to wear a dress as a disguise) has been variously depicted not only as a crossdresser but also as an actual girl.
- Male Naruto characters are often portrayed as female in fanart, referring to the "Oiroke no Jutsu", a technique created by the title character that allows him to transform himself into a voluptuous, naked woman as an illusionary tactic.
- OS-tan, which depicts non-gendered objects as gendered characters.
