Naruto from Naruto Shippuden, but this is when he goes berserk versus Orochimaru/Pain and goes into this particular transformation.

Positive Prompts: 4TailedBeastN, humanoid, fox ears, red body, black face, white eyes, no pupils, 4 tails, claws

Most of his scenes in this form has him crouching or being on all fours, so do your best to play around with the positive/negative prompts along with the LORA weights to make him not do that so much in your generating. 0.7 - 0.8 seems to be a good weight for flexibility for posing.

Putting "red aura" in the positive prompt seems to give it the more authentic look.

Put "mask" and "fur" in the negative prompts, so it makes it more accurate to the anime's look. Female variant of this form works great too if you want that.

I meant to change the trigger word to "4TailedFormN" instead before creating this LORA, so my mistake for not labeling the form correctly. Fake fan moment.😂
