But mostly hilarious lmao. Does this come with any pre-existing and working defaults?

Thanks for reply.
You mean say other default custom character?
I have less drawing skill, so any sprite(for destributable) cannot be created from nothing. sorry.
It would be nice if there was a license-free graphics(matched the atmosphere of factorio).

I mean, if I download this mod, will I get the anime character shown in the images? And if there are any other character options included in the mod itself, without having to do any other work.

About anime character shown in the "title images"?
She is the default character.
If you want to use her, You need to not unpack and modify this MOD.
