Trained on a large dataset with images of Red Sonja and Conan.
Usage and notes:
Positive prompt for Conan: 1boy, Conan
Positive prompt for Red Sonja: 1girl, redsonja, green eyes
You can make Red Sonja's design more consistent by adding redhead and bikini armor
If you add comic to the prompt then you'll get a style that's similar to what's in the comic books.
Female characters might tend to squint or keep their eyes closed, but if you specify an eye color then it doesn't happen.
Characters tend to frown by default. I guess no one is happy in the Conan universe.
