Best result in MeichiDarkMix_Reload and Prefect Pony XL so far.

Spider-man:

1boy, spider-man, bodysuit, red bodysuit, superhero, mask,skinny,

Unmasked Spider-man (should be able to have him wear regular clothes by omitting bodysuit references entirely, but haven't tested it):

1boy, spider-man,, bodysuit, red bodysuit, superhero,brown hair,thick eyebrows,brown eyes

Battle damaged Spider-man (I haven't seen the battle damaged mask activate, but if you trigger it, please post it. It's somewhere in there):

1boy, spider-man, torn bodysuit, superhero, damaged mask,skinny,

BEWARE THE FOLLOWING PROMPTS:

webline,holding webline,webswinging,spider web print,armpit webbing

They will mess you up. I had hoped including webswinging language in the tagging would help use this character in webswinging poses/work as a backdoor webswinging pose model. But no, it just throws webs and weblines everywhere with no rhyme or reason. Sometimes it will throw this stuff in anyway, in which case using them as a negative prompt should solve it.
