Univolt from Palworld. Trained on game screenshots. CHaracter works both Male.female Anthro/Feral. I had the best luck with Furrytoonmix, though WaiIllustrious and NovaFurry work well enough.

Primary prompt: Univolt

Supporting prompts:

Yellow fur, green skin, yellow accents, yellow helmet, beautiful red eyes,, biped (Biped if you want anthro. Also "anthro" if you want anthro.)

Horse, adding horse tends to botch the lightning tail, but does wonders for stabilizing the characters head/helmet configuration.

I've found prompts like lightning tail, or lightning crown tend to add lightning to the background instead of the character.
