I did some experimentation with various Zelda characters and races and figured out the following:
The AI recognizes the following characters and can get their basic design down well enough:
- Link
- Zelda
- Ganondorf
- Impa
- Saria
- Malon
- Gerudo
I decided to try out some newer characters and the following also work:
- Urbosa
- Sidon*
- Mipha
- Revali*
- Midna
- Zant
The AI does NOT seem to recognize any of the following:
- Darunia
- Goron
- Nabooru
- Ruto
- Sheik
- Sheikah
- Daruk
- Girahim
- Zora
- Kokiri
- Korok
In most cases if I don't go more detailed than that, it still at least gets the "bare basics" down. Saria will usually result in a green haired elf girl with green clothes, for example.
*Sidon and Revali have "red humanoid shark" and "blue bird" respectively, but that's about it. Very loose.
Gorons... I guess they kinda recognize it, to a very limited extent. But they turn out terribly every time.
