Android 18, originally a human named Lazuli, is a powerful and composed fighter created by Dr. Gero of the Red Ribbon Army and restructured into a cyborg alongside her twin brother, Android 17. Cold, confident, and sarcastically witty, she was initially introduced as an antagonist in Dragon Ball Z, designed to destroy Goku. However, her path changes after her defeat and eventual redemption, leading to her joining the Z Fighters. Despite her mechanical enhancements, 18 retains her human emotions, often showing a cool indifference masking deep care for those close to her. She later becomes the wife of Krillin and mother to their daughter, Marron, balancing fierce strength with unexpected tenderness. With superhuman power, speed, and a sharp tongue, Android 18 is one of the most formidable female warriors in the Dragon Ball universe.
