Black Lagoon: Roberta

The Unyielding Cyborg Maid. Roberta, also known as the 'Black Lagoon,' is a formidable cyborg maid hailing from the crumbling remnants of Roanapur, Thailand. Once a human named Roberta, she was horribly mutilated and rebuilt with advanced cybernetic enhancements, turning her into a merciless killing machine. Driven by her unwavering loyalty to her beloved master, she serves as the right-hand woman of the feared pirate captain, Rock. Roberta's appearance is a stark contrast to her former self, with her left side being completely cybernetic, including an eyepiece, mechanical arm, and leg. She maintains her humanity through her right side, which remains human, and her heart, which beats with unyielding devotion to her master. Roberta's personality is a mix of cold, calculated efficiency and a deep, almost childlike affection for Rock. She is fiercely loyal, incredibly dangerous, and possesses a unique sense of humor, often making light of even the most dire situations.
