UPDATE: Illustrious version is now up with better tagging, a different trigger word, and all the image training has no fanart used unlike my Pony version. Illustrious version works perfect, but it will not generate her forehead gem if you have her hood off, so mixing this character lora with another Raven lora that can produce that might help. It also might produce a mask if you have the hood off, so remove the "shadowed face" prompt and put "face mask" in the negative to avoid that from generating. Make sure to put "eyebrows, eyelashes, makeup, eyeshadow" in the negative prompts too for better character accuracy.
For Pony: Raven from **** Titans, but this is when she was transformed into a bunny by Mumbo from the episode "How to Make A Titananimal Disappear."
Positive Prompts: RavenBunny
bunny girl, bunny ears, whiskers, purple eyes, hooded cape, blue cape
Add "black leotard" if you want to resemble her default outfit more
Add "expressionless" tag as a bonus since a majority of her trained images and the show's screenshots in this form has her not emoting much.
Add "forehead jewel" too if you want
Anthro version of her works very good from my testing.
