I never fiught sans. At the begining, I went for the true pacifist ending. I never hit the reset button.
Sans is sort of in his own category in my mind, along with another character who wasn't included in the poll, I'm guessing for spoiler reasons. I have to go with Undyne. She's cool and her pacifist fight mechanic is really creative. I really like them all though.
I love all of them though. ...But if I had to pick one, I would go with Toriel. As a tutorial character, she has a lot of charm and background. Also, her punting Flowey off the screen gets me every time. XD
hOI IM TEM Aside from that I really like Undyne I guess. She's just got a lot of character to her that I like.
For the longest time, it was Papyrus just from the footage I saw. Then I finally played the game and got to Undyne. She is the epitome of awesome and funny rolled into one. "WE'RE GONNA BE BESTIES!" Plus, while Alphys was probably my least favorite reoccuring character, I did find her relationship with Undyne adorable.
It's a tough pick. I really want to choose Alphys, because aaaa Alphys is meeeee aaaa. But self-deprecation jokes aside, Goat Mom is best mom, and even though Toriel doesn't make a recurring appearance until the end of the Pacifist run, she touched my heart in one of the closest ways I can imagine in a game. I could go on and on about how Toriel was meant to touch you that way in terms of the character design and the rest of the game, but something about how her mere existence orchestrates your survival is beautiful.
My favorite character is Spoiler: Undertale True Pacifist Spoilers Asriel Dreemurr They most likely aren't on this list because of spoilers. Oh and another favorite is Spoiler: Undertale Genocide Route Spoilers Chara
NYEHEHEHEH! THE GREAT PAPYRUS IS EASILY THE BEST OF THEM ALL! I mean come on, what is there not to love about this guy?
