The term "transfur wolf" likely originates from the furry fandom or specific media like the game "Changed" (by DragonSnow), where characters undergo a transformation (a portmanteau of "transform" and "fur") into anthropomorphic creatures. Here's a breakdown:

1. In the Game "Changed":
In Changed, the protagonist is infected with a virus that slowly "transfurs" them into a furry creature. A "transfur wolf" could refer to a wolf-like creature in the game or fan-created content depicting such transformations.
The game features various "transfur" outcomes, including wolf-like beings, as part of its body-horror and puzzle-solving narrative.
2. Furry Fandom Context:
In the furry community, "transfur" is slang for a character transforming into an anthropomorphic animal. A "transfur wolf" might describe:
Art or stories about a person turning into a wolf-like furry.
Role-playing scenarios involving transformation.
A character design or species in furry art.
3. Other Media:
The concept overlaps with werewolf lore or transformation themes in anime/manga (e.g., Wolf's Rain, Wolf Children), but "transfur" specifically ties to furry culture or Changed.
If you're referring to something specific (e.g., art, a character, or a game mechanic), feel free to clarify! ✨
