Drawing 'Undertale' characters like Sans and Papyrus is such a fun creative challenge! For Sans, start with his iconic skull shape—keep it rounded but slightly angular for that cheeky vibe. His eye sockets should glow, so sketch hollow circles first, then add tiny white pupils. Don’t forget his toothy grin; it’s asymmetrical, like he’s always up to something. His hoodie’s oversized, with a high collar, and those shorts? Comically short. For Papyrus, exaggerate his lanky frame. His skull’s more elongated, with dramatic eye sockets and a permanent, confident smirk. His armor’s angular—think sharp shoulder pads and a chest piece with a stylized 'delta rune.' Both thrive on bold lines, so ink confidently!
For shading, Sans’s shadows are minimal (he’s lazy, after all), but Papyrus deserves dramatic contrasts. Use deep blues or purples under his jawline. Backgrounds? Maybe a spaghetti-stained table for Papyrus or a starry void for Sans. Pro tip: Their expressiveness lies in posture—Sans slouches, Papyrus strikes heroic poses. And if you mess up? No worries! Their designs are forgiving. Just lean into their quirks, and your fanart’ll ooze personality.
