For this model, I mostly just tried to teach it the appearance of his different forms. NovalAI/Anything already knows enough about Goku to use this model at lower settings, such as 0.5 or 0.6.
This model is somewhat janky so don't get your hopes up too much
It was trained on his base form, super saiyan, super saiyan 3, super saiyan god, super saiyan blue, and mastered ultra instinct. Most forms work decently enough, but Super Saiyan 3 has a lot of issues.
