Trigger word is 'sierrago'.

There weren't many images of her out there, so some details (like the side satchel and bow on back) are omitted, while details such as the 'Red R' on her suit will only sporadically show up.

Works well with 'upper body' images, 'full body' images need Hires. fix to come out well (so generate without hires fix and then pick the best pose/look to upscale).

More information you can specify:

smirk, purple lips, lipstick, hair bun, hair pin, brown eyes

Place this in positive prompt if you want to see her hold a PokeBall, or negative if not:

holding, poke ball, poke ball (basic), holding poke ball

0.7 strength and CFG Scale 9 works well and also mixes quite well with art style or pose LoRas, but your mileage may vary. See example images for inspiration.
