Generating Siblings Based on a Reference Character

Prompt

This is a prompt for Nano Banana Pro that generates a character’s siblings based on a reference illustration.  It works just by specifying things like “younger sister” or “older brother” in the prompt. It may also work for mother, grandfather, and so on.  You can specify not just one person, but multiple people as well. You can also specify each one’s characteristics. The first image was generated using the following:  {argument name="siblings to generate" default="one younger sister (funky), one younger sister (subculture style), one older brother (musclehead), one older sister (shut-in)"}  You can also customize the size, not just the original format, but also portrait, landscape, square, and more.
