Nina A Thunder is an eX-Driver who operates out of the Los Angeles branch of the organization. She has long blonde hair and blue eyes. Before the events of the main éX-Driver series, she worked alongside fellow eX-Driver Rei Kazama, and the two are the central figures of the prequel éX-Driver: Nina & Rei Danger Zone. In that story, they investigate a series of mysterious runaway incidents involving invisible AI-controlled cars, which leads them to confront hidden threats. Nina is a highly skilled and experienced driver, confident behind the wheel and capable of handling a wide range of vehicles, including cars and motorcycles. She is quick-thinking and resourceful, often taking decisive action in high-pressure situations. Her motivation stems from a strong sense of justice and a commitment to protecting others by stopping rogue AI vehicles. She forms a close working partnership with Rei Kazama, and their combined abilities allow them to tackle dangerous missions effectively. Nina is assertive and self-assured, showing little hesitation in pursuing her objectives. Her character does not appear in the main OVA series beyond the prequel film, leaving her development focused on this earlier chapter of her career as a capable and dedicated eX-Driver.
