Krillin could be developed by showing his growth from being a bit of a coward sometimes to a more confident fighter because of his relationship with Android 18.

I'm not sure if there is a non - adult version specifically. It might depend on the developers or fan - made projects. Sometimes, in the world of fan - created content, there could be versions that focus more on the story and characters in a non - sexualized way. However, it's not very common as the original concept might be associated with some adult themes in the minds of many.
