Who is Lewis? Do you recognise him? You don't . He's a creation of Stable Diffusion and is here for your use in your prompts.
I recommend you use ADetailer to show it at its best.
I was looking at the Nobody characters and as well as not many more normal looking people, I realised what would be useful is actually stock characters of types. If you're doing a story, you need certain sorts of people. There's many more women than men who've been trained as characters, but looking at the few men who have, I realised there's no basic nerd. Lewis is my attempt to cast a more nerdy guy. Hollywood nerd, but nerd enough for us.
Any more types you'd like to see? Just say.
