Reign/Samantha isn't a Kryptonian. She is a killing machine designed to destroy with the combination of many bits of DNA to make her the strongest. Some is Kryptonian, but not all of it. Then again, it might be different for the show, but that is how it is in the comics.

So Ruby probably is a World Killer unless the human DNA from the father countered against that happening when she gets of age. As Sanctuary did say that the child "got in the way"
