tested it on AnyLoRA and AbyssOrangeMix2 with my negative embeddings and it's pretty convincing at weight=1 for the offset version and 0.65 for the original (check "original" tab for a comparison). Use the prompt jim lee for better accuracy.
Keep in mind that, while this can make Superman, Batman and Wonder Woman pretty well, this is not a character LoRa but a Style LoRA. Have fun making your own superheroes!
