This model can do both fantasy characters as well as sci-fi androids with "intricate" armour pieces. I used realisticvision v2 with this LoRA to generate the images. You can use "science fiction" or "high fantasy art" to get the genre but by default the higher weighting leans towards fantasy anyway, but has limited (mostly side profile) poses. I have mostly focused on sci-fi though in my samples...

Keywords to use as needed are magic-fantasy-mech, 1boy, 1girl, 2boys, 1mechanical and the above genres.

So, some examples:
