In the Underfell alternate universe, the central dynamic of the skeleton brothers is inverted from original game norms to fit a harsher, "kill-or-be-killed" underground. Underfell Sans Personality: Unlike his easygoing classic counterpart, Fell Sans is stressed, defensive, and rough around the edges. Living under constant pressure, he is forced to address his younger brother as "boss" to survive. Despite his hostile exterior and foul mouth, he harbors deep, hidden protective instincts. Appearance: He wears a heavy black hooded coat with white fluff and a gold zipper, a red turtleneck sweater, black sweatpants with yellow stripes, and red-and-white sneakers. He has sharp teeth (including a gold-capped canine) and permanent bags under his eyes from exhaustion. Abilities: He utilizes red bone attacks and multi-eyed Gaster Blasters. Underfell Papyrus Personality: Papyrus is ruthless, ambitious, and a high-ranking member of the Royal Guard. He projects a terrifying, authoritative aura, demanding absolute obedience. However, he secretly maintains a complex layer of care for his brother—even stepping in to save Sans from execution at a heavy personal cost. Appearance: Taller than Sans, he features sharp teeth, a facial scar over his eye, and a distinct battle body consisting of a spiked black-and-red suit, a red cape, gloves, and heeled boots. Abilities: Exceptionally powerful and nearly matching Undyne in combat strength, he wields sharp, spiked, and orange bone attacks alongside signature blue gravity manipulation.
