Model of Char Aznable trained only with images of his appearance from Mobile Suit Gundam (The origin), so, you will only be able to generate this appearance.
I wanted to use images from the 1979 anime, but the anime is so old that the Lora was going to end up taking that style, and I would understand if that is not to some people's liking.
Tip: You may find that by using prompts like “looking at viewer” or similar and then applying adetailer to the face, Char's mask ends up showing his eyes. To avoid that you can put “vissible eyes, eyes” in the negative prompt or choose prompts that do not have to do with looking.
Example: replace "Looking at viewer" for "Facing viewer"
