- Type: Attribute / Change / Visual
- Description: A character's body changes gender from their usual one. May invoke transformation if it is shown as a sequence and not a sudden change.
- Note: Should not be confused with body swap or crossdressing. A female becoming a futanari does not count (but may qualify for dick growth). Possession of a person of the opposing gender is acceptable.
- For parodies (e.g. female ranma saotome) the change does not have to be shown.
- Presence includes post-transformation images.
