Krea2:

Use strength 0.7-1.0, I think ~0.9 is a good start; some details like the glove should be "baked" into the character. The ghost trap and proton pistol don't work well. I kept the "nurse" picture as an example of poor results. This tube actually is proton pistol cable. Overall, this version is much more stable compared to Pony. Partly because I twice fully remade the dataset from scratch.

Pony:

First time trying to create a character instead of style or real person. Not bad as I expected, not good as I want.

After more than a hundred tries and many experiments, I've managed to create a pretty fine version; however, this is still not satisfying for me, especially because of those damn straps of armor (I really hate struggling with them, they are still not so stable to use, but much better than earlier). Use a strength 0.9-0.7. There are two blocks of trigger words, and although using 'navy' a few times in them isn't a good decision, it's a smaller sacrifice. The bad part of it is that if you want the original outfit, you could end up with blue armor or just a bodysuit; therefore, put 'orange armor' in your prompt as early as possible or/and increase its strength.

I don't recommend using those versions below.

Versions (0.5 and 0.7) work badly with realistic checkpoints or loras. Unfortunately, I didn't find enough good quality images with a proton blaster beside TV series.

There is an experimental feature in V0.7( keyword: 'holding proton blaster') to make her holding a proton blaster. It is very not stable, use it only if you're really ready to do many generations and edit it with img2img or/and graphical editor. The example is in the OP, the last one picture.
