As an aspiring member of the Royal Guard, the great Papyrus not only trains really hard, but works really hard to help his friends whenever they need it most (and when they don't)!  Papyrus can be considered a friend to most due to this, and his brother Sans often keeps him busy due to his laziness.  He loves puzzles and cooking spaghetti, and he often will cook some regardless if it's good or not.
