Undertale opinions and small stories

"Who is the actual villain in Undertale?" This will all be my main opinion. I'll be defending some of the proposals that people have said and I will be against some. Whatever I say in the book is only my opinion I will occasionally use info I got from someone else or from another site. If this stuff does occur I will tell you what is not mine so you guys know. I will also occasionally include art in the book. I will even talk about characters which people don't care about that much which is sad sometimes cause almost all the characters are interesting in their own ways. Current cover will change soon trust me and is not mine.
