Papyrus

Papyrus is an optimistic, albeit naive, skeleton and a major character in Undertale. He is the younger brother of Sans and is obsessed with becoming a member of the Royal Guard to gain friends and popularity. He uses his unique bone magic, which includes manipulating gravity and generating bones, to try and capture a human. Despite his initial goal, he ultimately becomes a loyal friend to the player, and his kindness and innocence make him one of the game's most sympathetic and popular characters.
