Since I don't know how to train XL models like I do LoRa outside of the Civitai trainer I'm just going to post this one since one for the suit already exists, my favorite granure murderer let's gooooo!
Since most artist depict him with his outfit from episode 1 the other hoodies (Yellow, Red) and the stomach zipper are not happening and if they are it's not on purpose, neither the Red Gavv, I tried finding drawings depicting his gavv but no such luck.
Prompts:
Shoumagavv
I also reccomend adding these:
blue hoodie, yellow accents hoodie, turtleneck hoodie,
Those will give him the signature hoodie, if you don't you usually get the blue one without the turtle neck nor the yellow accents. Also try to pair it with a hands LoRA because sheesh.
