to keep close to his old design try any of these - or put in Neg to reduce chance - SFW/NSFW
may need to add 3d, or realistic, in neg for certain 2d/anime styles - lower weight for less 3d influence - 0.8 between 0.6
may update standard to v4 at a later date
Ponyxl TW is Toanxl, - may have more 3d influence
For appearance
Toan, brown hair, brown eyes,
if you want to keep him consistently male, could add flat chest, when not wearing poncho - I suggest adding things like breasts, 1girl, in NEG - some NSFW results may shrink body size due to the ps2 (game) model training
femboy, or otoko no ko, in prompt may enhance/exaggerate depending on style used - or shota, in NEG which may help reduce smaller builds
for attire
orange poncho,green hat,belt,brown gloves,black pants,white neck wrap,red waistband, brown boots,
belt pouch, may spawn randomly
without a hat, ponytail, or hairbun, may spawn randomly
his poncho, has red patterns, or red designs, on them - may not always spawn - due to have a lot of color specific prompts, some colors may need to be put in neg for attire
jewel on left glove may swap gloves, - may spawn brooch, on poncho
it may be possible to spawn his sword, but that may require some tool work
