Mephismon is a digimon and the main antagonist from the movie Digimon Tamers: Battle of Adventurers. It won't always generate the star icon on the chest correctly and it sometimes won't generate the red fur around his arm, but other than that, it'll nail the look at least.

Positive Prompts: Mephismon, furry, anthro, goat demon, dark red hair, grey body, black chest, dark red fur, hooves, orange sclera, black eyes, horns

Extras: black wings, demon wings

For an alternate eye look put "no pupils" and remove "black eyes" in the positive prompts.

You can also put "goat eyes" in the positive prompts if you want. Also, you are able to make a female version of this character, but it'll change the core design look a bit if you're ok with that lol.
