Kurama in his Tailed Beast Mode from the manga/anime Naruto Shippuden. This was a bit of a tough one to get down, but hopefully it works fine for the most part. Sometimes the black lines on his body won't generate properly, but the other than that it should get the look down pretty well. Just don't expect the AI to pick up 9 tails every single time lol.

Positive Prompts: TBMKurama, male fox, anthro, 9 tails, yellow body, glowing body, yellow eyes, no pupils, sharp teeth

Extra eye colors: white eyes, red eyes

Bonus: glowing eyes

You can remove "anthro" and replace it with "feral" if you want
