I learned an easy way to create fictional character embeddings, just by prompts and without any images from the following articles.

"Train OCs without Images | Automatic1111" by Mr. Monster

"5-second embeddings and how to make them" by tvange365

I would like to share some of my results here.

Since the effect of the embeddings depend strongly on the checkpoint used, I tested with 5 different models from anime type to realistic type.

qchar01: Asian, long black hair

qchar02: Asian, short brown hair

qchar03: Western, short blonde hair

qchar04: Western, long wavy red hair

All the images were generated by random prompts, using the "OneButtonPrompt" extension.
