V3 Is a return to the original model's style, with a bit extra. It should be slightly different, but I highly recommend checking the cover images of each model to see what you like most.

V2 is more stable and recognizes characters better (if you get the reference) If not, ultratwink is gabriel and Nikkon is V1. Still isnt great at gabriel's helmet, but this is a concept lora, not a character one. however, this all comes at the loss of the previous versions hard af style, so take it with a grain of salt. (moves more towards the actual style of the Ultrakill album covers: Really good if you want solid color backgrounds.)

E7 is for less Ultrakill and is more stable and varied, but harder to prompt well. Check images. (Personal favorite because I can get different backgrounds easier, like the floaty skelly)
E15 is for medium Ultrakill and is recommended for most use cases
E24 is for extra Ultrakill and suffers some stability problems, with a more emphasized style


If you enjoy the model, please be sure to post images or react to them, as this gives me buzz, letting me create more models and update the ones I have.
As with my other models, I do not ever support using my work for commercial purposes.
