An image containing the non-canon children of two known characters. The child is often either a fusion of their parents or resembles an aged down but otherwise identical clone of the mother. See science babies for the children of a same-sex couple.
Typically these are the children of a canonical couple or a popular fan pairing, but they can also be other established characters or even characters from unrelated copyrights.
If the child has its own tag, don't add the parents' tags unless they are also present.
