Who IS the most mysterious character in Undertale? Sans, Gaster, the Annoying Dog, or perhaps, Napstablook? Tell me, what do we really know about Napstablook's past? We know he was close friends with Mettaton, his cousin, before he became the star of the Underground, and that's it. So, I have a theory, one that will explain Napstablook's self-esteem issues and his connection to the True Lab. Also, I will call Napstablook a "he" times, because when I first fought Napstablook I thought they were male, and their gender isn't relevant to this theory anyway.

In the true lab, we see multiple logs (8, exaclty, I'll explain soon) from Alphys recording her expiriments, but in entry Number 9, the style of writing changes. The person writing does so in lowercase. There are only two monsters I know of who speak in lowercase, Blooky and Sans, like how Papyrus and Mettaton speak in Capital letters. At first, it might seem to be Sans, until Entry Number 11, when the writer says this:  I don't think Sans would say this, he doesn't care what Mettaton thinks of him. If it were Papyrus, he might say something like this, but Napstablooks constant use of the "..." gives us another hint of him being the one recording the entries. Later, he talks about how ASGORE found a teacup that looks like him, leading me to ask myself, is the Annoying Dog himself trying to lighten the situation, or trying to tell us something? Well, everything in the True Lab exists either to create suspense, and scare the player, or to give us backstory. Napstablook is roughly the shape of a cup, so a teacup could easily look like him, unlike someone like Alphys or Sans. Later, he says that he spends all his time in the Garbage Dump.
 * now that mettaton's made it big, he never talks to me anymore. ... except to ask when i'm going to finish his body. but i'm afraid if i finish his body, he won't need me anymore... then we'll never be friends ever again. ... not to mention, every time i try to work on it, i just get really sweaty...

Now let's talk about Napstablook has self-esteem issues. Everyone is mad at him because he's been lying to them. He goes to the RUINS because there, nobody knows what he did. He isn't used to people being nice to him after what happened, so he assumes you won't either. Perhaps Muffet and Mettaton were the few people willing to forgive him. Technically, Napstablook pretty much created Flowey and the Amalgamates, so we have reasons he doesn't even know about to be mad at him. However, that also means that without him, Flowey would have never absorbed the SOULs and become the God of Hyperdeath, so Napstablook, in a way, freed the Underground

However, this doesn't explain why exactly Napsta was doing in the True Lab, why his logs replaced Alphys's. Nor does it explain what Napstablook's relationship with Gaster may have been, if he even had one. Could Blooky even use Gaster Blasters? I don't know, so what are your thoughts on this?
