EDIT:Now in Illustrious, I recommend a furry focused lora for this if you want to use animal features as base Illustrious isn't as good. For other tips see version details.
Here it is, my first concept lora. The ability to make a character into a kaiju or to make your own kaiju. Definitely going to improve this one later but still happy with how it came out. Be sure to be descriptive with your tags. Claws, sharp teeth, tail, fins, wings, spikes, shell, and more all work. Check example images for most of them.
Description
Spikes,scales,anthro,furry, and scalie are helpful. Monster gives more non-human results.Giant monster gives better size results than giant or giantess if you need the help with that.Fusion helps when an Animal/Pokemon/etc doesn't want to merge with a specific character.
