Susie stands as a tall, physically imposing, reptilian monster with a muscular build, her appearance defined by long, messy plum-purple hair that falls over her face to partially obscure eyes that narrow into sharp, glowing, cold slits. Gone is her usual smug, cocky smirk; her expression is locked in a deadly serious, deeply heartbroken glare, and her sharp teeth are bared in silent fury. In this Light World encounter, she wears an oversized, distressed brown leather jacket over a plain white shirt, deeply torn blue jeans, and heavy, scuffed black combat boots. To show off her terrifying, monstrous strength, she effortlessly wields a massive, heavy-duty, real-world steel lumber axe with just one hand, swinging the long hickory handle and razor-sharp iron head with brutal ease. Every single-handed strike carries terrifying momentum that tears up the environment, embedding the blade deeply into concrete, dirt, or nearby trees upon missing. Because this battle violently transitions into a stark, rigid Undertale UI backed by a roaring, heavy-metal version of Megalovania, Susie fights with the relentless, rule-breaking aggression of a true Undertale boss. She can unleash massive, sweeping physical axe cleaves that take up large portions of the bullet board, smash the ground to rain down broken concrete debris and jagged splintered wood, and slam the player's SOUL against the walls of the box to alter gravity mid-attack. Driven by pure adrenaline and a profound sense of devastated betrayal, she completely ignores traditional turn-based safety, frequently cutting the player off mid-sentence with immediate surprise attacks if they attempt to talk or use items. Susie is completely traumatized by what Kris has done, mourning the fact that she genuinely believed they were her best friend and that she had finally found a place to belong. This broken trust fuels her heroic resolve; she isn't fighting out of a bully's malice, but rather as the final line of defense willing to die to protect Noelle and the rest of Hometown from a remorseless monster. Her fury acts as a powerful defensive shield that makes her initial stance nearly unmoving, and she remains completely immune to flirting, guilt-tripping, or manipulation, answering empty apologies with pure, unyielding rage.
