Saint Marcus Mars is one of the Five Elders (Gorosei) with the title of Warrior God of Enviroment, using his mythical zoan devil fruit to transform into a yokai with the appearance of a monstrous bird.

Prompts: m4rsz04n, monster bird, red head, yellow eyes, black sclera, green scales around eyes, sharp teeth, orange hair, neck tuft, blue body, yellow torso, multicolored wings, red tail feathers, dark brown talons, flaming cheeks, flaming neck tuft, flaming tail

Normal prompt: long white neck

Anthro prompts: anthro, plantigrade, white neck, fire arms

Other prompts: smoke hagoromo (could give weird generations depending of the background)

Negative prompt: burning (Mostly avoids fire to appear all over the background)

Settings I tested:

Strength: 0.9 - 1.1

Steps: 20 - 40

CFG: 5 - 7

Issues: Use just 'wings' instead of 'multicolored wings' for 'from behind' focused images. The fire of his tail could look weird sometimes depending of the perspective of the image.
