SaveLoadReset analysis this character here:http://saveloadreset.tumblr.com/post/152206205168/who-was-grandpa-semi

Basically, he was found by datamining Undertale's demo. Named after a font, just like the Skelebros and Gaster. Really, my main hypothesis is that it was the previous Royal Scientist, and I just gave "Grandpa Semi" as an example as to who said scientist might have been. (If the Skelebros did come from Gaster, and Gaster was their father, Grandpa Semi would be Gaster's father, and a prime candidate for the Royal Scientist before Gaster.) Of course, just as SaveLoadReset themselves said, it's also possible that Grandpa Semi was simply a previous incarnation of Gaster.

..But maybe there's some hidden piece of evidence I'm missing that proves Gaster was the first. I'll be analyzing what the Followers have to say about Gaster..
