Well "Gaster is Skelebro's father" theory is pretty much the most popular one. I have feeling that even Toby himself might just go with it.

But yeah, we have so little canon information about Gaster, so there is high chance that most of super detailed theories might be untrue, no matter how good/interesting they are... Was it Toby's intention to just endlessly theorize about him?
