This character Lora works well on checkpoints that handles non human characters. Yet, with checkpoints that tend to cater to nonhuman characters and highly realistic looks, the results tend to be mutated.

The default strength for the Lora is what I would suggest to make sure the results closely matches the original look of the character. A Lora strength of 0.85 would give a Cooler themed style for characters, and a strength above 1 would result in messy images.

For trigger words beyond Cooler, listing the artists (art by Akira Toriyama:1), the artist behind the famous manga and anime, would help with better results. Also, the terms 'face mask' and 'white armor' helps as well due to the program thinking that the face mask area of Cooler is a mouth with clenched teeth for some reason.

The first version of this Lora is largely based on old screenshots of the Revenge of Cooler movie made in 2008, so I had not much to work with. I intend to find a way to make better screenshots or find better examples for this Lora for a nicer version 2.

For the rest of the stats, the usual default stats with DPM++ 2M Karras sampler makes for a good results with a checkpoint that works well with the Lora. This Lora also works very well with most of the tech Loras made by navimixu.
