I was looking online, and I got genuinely annoyed there just wasn't a good lora/TI on Krystal, much less only based on her look from Star Fox Adventures/Assault, so heck it I took the time and made one,

Trained on AnyLora, so pretty decent compatibility with most semi-realistic/illustrative models

Setting the Lora to 1 may be a lil' strict, I would play around with a range 0.7- 0.4 for best results, any higher and the lowpoly-ness of her gamecube iterations rears its head lol (refer to the weight chart for reference)

Triggerword is krystalodd, if details get lost just add some variation of 1girl, furry female, furry, fox girl, fox ears, fox tail, aqua eyes, blue hair, short hair, bangs, two tone fur, body fur, blue fur, white fur, and that should help maintain likeness

For Her Star Fox Adventure Outfit:

arm tattoo, leg tattoo, circlet, red gemstone, yellow bandeau, strapless bra, shoulder armor, gold armor, loincloth, vambraces, gem, blue gemstone, neck ring, shin guards, sandals, collarbone, cleavage

For her Star Fox Assault Outfit:

blue bodysuit, high heel boots, circlet, clothing cutout, cleavage cutout, blue gemstone, cleavage, collarbone, medium breasts

or alternatively use those if you don't want those to pop up

Have Fun!
