Lulu

Lulu first appeared as a mysterious girl rescued from the shoreline by Smith. Originally functioning as a biological battery powering the enemy faction's Death Driver, she could only produce unintelligible sounds like "ga-ga-bee" in her earliest days. Through Smith's dedicated care, she rapidly developed self-awareness and grew into her own identity. After Smith sacrificed himself for her sake, Lulu inherited his passionate spirit and courage, achieving a "Courage Fusion" with Superbia and emerging as a vital combat force fighting alongside the multinational allied forces.
