You know, I think what makes Papyrus and his boastfulness so endearing, despite egoism usually being a negative and unappealing character trait, is the fact that his self-confidence does not exist at the expense of others. He doesn’t build himself up by putting other people down; he thinks highly of everyone! He can consider himself great and admirable while still genuinely being impressed by the people around him and celebrating their accomplishments.
Papyrus understands that greatness is not a competition; it’s something everyone can win at! And even if he is the greatest, it’s only so that he can show everyone else how to recognize their own inherent value.
Papyrus believes in himself! Papyrus believes in me! Papyrus believes in you, too!
