Papyrus and Sans are brothers and characters of the game Undertale, but they are very different in their deeds. Sans wants to help people, as Papyrus wants to capture them. Sans in Undertale even hides the player so that Papyrus couldn't find him and capture him. Sans believes that Papyrus was tricked with an echo flower to do all those nasty things he does. Sans cares for his younger brother Papyrus and thinks that Papyruses aim to capture humans so he can become a member of the Royal Guard is wrong.
