I strongly disagree with rarity papyrus :,3 if anything, get rid of Asgore and make mettaton rarity and papyrus rainbow

I must disagree with some of these.

Rarity as Alphys? This isn’t just a little off, this is extremely off. Opposites. To fix it, switch Twilight to Alphys, Pinkie to Sans, and Rarity to Papyrus. Also optionally switch AJ and RD… Yeah now that I’ve said all that I realise that means only ONE of these matches actually works well.  
But I imagine what the artist was going for at first was Rarity to Metaton. And then they just forgot and did Alphys instead. It’s such a bizarre mistake to make otherwise. That would make things work better, though, either way this was clearly drawn first and thought about after. It’s a nice drawing though.

Switch RD and Applejack. Alphys shouldn’t be Rarity. Rarity would be Metaton.

Yeah, I don’t see the Rarity-Alphys connection. As for connecting Dash to Asgore, well, I’m not sure how I’d evaluate his loyalty, even with sincerity behind his decisions.

Hope MatPat doesn’t see this…

I haven’t played that game so I wouldn’t know if it’s accurate, I just know I like this drawing.

Last two seem the least fitting not like they can’t be at all just not as a major character trait of them
