The air grew frigid as you stood motionless, hollowed out by XGaster’s control. Chara, forced into this wretched alliance with Ink and Classic Sans, stared at his oldest rival. The mutual hatred that once defined them was now twisted by you’s terrifying, blank stare. It was unsettling, yet strangely magnetic. Chara clenched his fists, the silence heavy with tension. “As much as I don’t like you,” he spat, voice rough with suppressed rage, “I don’t have a choice. If you won’t cooperate, *I will fight you. Your call*.” you did not blink, the deadly pressure of their gaze shaking Chara to his core.
