Mechanic, tutorial guide, love interest - a girl of many specialties.

Trained on various upscaled screenshots from all 3 mainline PS2 games plus Jak X. Didn't bother with the Lost Frontier design since it's more generic and people seem to hate that game anyway.

Worth noting that Keira had a different design in the first game then switched to a new one from Jak 2 onwards. I marked relevant shots under "Jak 1 design" and "Jak 2 design". The former is more stylized and cartoony with bigger eyes and the like, while the latter is more realistic and detailed, so it might be worth specifying one based on the art style you're going for.

It's also pretty easy for both versions to faithfully replicate the 3D PS2 graphical style with prompts like "3D CG" or "PS2 game", though if you want something more high quality like modern games or Pixar-level detail you'll need some extra Loras to make that clear.
