Hahaha yeah! Im in the fandom of undertale :)
I didnt played it,but I watched the game and comics that fan did around this story and I have to say that they are sooo funny and cool :D
One of my favorite ones is Sans :) He's cool,funny and always with a big smile of da face (Being a skeleton helps I think)
Asriel is too cute and innocent to not like him...even if he tries to destroy everything at the end he's good ^^ (and he's sooo cute :3)
I really thanks Toby Fox for the game x)
