Works very well (wow, Pony Diffusion can do furries well, who would've thought).
This Lora can generate both regular and shiny Mega Absol, wow ✨
The trigger word is "Megabsol".
Helpful tags:
pokemon \(creature\) -- the usual
white fur, wings -- for accuracy, may not be necessary
blue skin, red eyes -- for regular Mega Absol
red skin, blue eyes -- for shiny Mega Absol ✨
hair over one eye -- specifically if you're going for that look
