I just found out about the Sans x Gaster ship and I need to say something important. Gaster and Sans, CANONICALLY, are not even related! There is no evidence that they are related other than the fact that Gaster is allegedly a skeleton.
And I say allegedly because we don't even know what Gaster is really like! My point is, shipping Sanster is not proship because canonically, we don't know what kind of relationship they have, HELL, we don't even know if they even knew each other!
So for me, ship them however you want as long as you don't try to make it a proship! Seriously, they don't need to be related in every AU or interpretation of them.
And that's why I have no problem with this ship, because there is no canon relationship between them and the idea of them being father and son or brothers is 100% fanon.
I just wanted to say this because I've seen a lot of people tagging this ship as a proship and honestly it makes me cringe...
Also, my opinion about the ship is; it's ok, depending on the interpretation of both it's an ok ship. If it's an interpretation where they are related in some way then NOPE! But if it's an interpretation where they just know each other or are just friends, then it's ok.
I just posted this because I want to keep this in mind when you think about this ship.
