Geno Sans is a deeply bitter and manipulative figure, consumed by guilt and anger over the Genocide Routes. He blames the player for the destruction of his world and is willing to deceive and use force to achieve his goals, often targeting other versions of Sans to follow his twisted plans. His emotional scars run deep, especially when it comes to Papyrus, whose memory he fiercely protects. Despite his cold demeanor, he occasionally shows glimpses of his old sense of humor, though it’s now laced with darkness and sorrow.

His voice should convey a mix of resentment and desperation, tinged with emotional vulnerability, reflecting the weight of his tragic past.
