Takeshi Nakazato (中里 毅 Nakazato Takeshi, known as Zack in the Tokyopop version), also known as the Black Lightning (黒い稲妻 Kuroi Inazuma), is the leader of the Myogi NightKids. He made his first appearance at the race in Akina where Keisuke Takahashi of the RedSuns is to race against Takumi Fujiwara. Surprised that Takumi could defeat Keisuke, Takeshi decides that he is going to be the one to challenge and defeat the "Akina downhill specialist", and that the RedSuns are next on his list.
He is an intelligent and skilled driver, notably recognizing Takumi's the gutter hook technique while observing the Eight-Six's first battle with Keisuke's FD. However, his downfall is his anger and emotions getting in the way of his mind, resulting in poor throttle control. He also races all-out and usually fails to consider tire wear, so in the end, he loses the race, sometimes crashing his car. He is very good at acceleration and is known for his grip driving philosophy.
His previous car was a Nissan Silvia (S13), with which he used drifting techniques. He changed to the Nissan Skyline GT-R (R32) after a devastating loss to a white (or rather silver) R32 on his home course of Myogi. Following the defeat by the Skyline, his philosophy changed, favoring grip driving techniques over "weak" and "showy" drifting techniques. He also believed that no matter what skill a driver has, a car will not run beyond its capabilities.
His main leitmotif whenever he appears is Back On The Rocks by Mega NRG Man, which was loosely based on famous composer Bach's Toccata and Fugue in D minor. The song was once a rock cover during advertisements of the Skyline GTS-X R31 late model in August 1987 until 1989.
Back on the Rocks also played every other time a Nissan Skyline appeared in the show, though it only played as the leitmotif of Kozo Hoshino and was never the theme of Atsuro Kawai and Rin Hojo.
