Gustav 1

This is an Illustrious XL exclusive character LoRA, trained to generate a towering evil muscular demon king.

The model perfectly retains core features: massive hyper-developed muscles, small black demon horns, long dark brown hair, goatee, menacing evil facial expression, and iconic white fur-lined cloak. It supports multiple outfits: original dark purple noble vest, bare upper body, and tight black briefs for stronger oppressive aura.

100% natively compatible with all Illustrious series SDXL base models, no obvious feature loss or figure distortion. Recommended LoRA weight: 0.75 ~ 0.85.

Best for creating full-body / half-body anime illustrations with dark hell-themed backgrounds.

Not compatible with SD 1.5, standard SDXL 1.0 base models, Pony XL or FLUX. Do not use it to draw female characters, children, cute cartoon styles, or soft bright pastoral scenes.
