By 2030, Shotaro's son was in charge of Tetsujin-28. An Interpol agent like his father, he used the aged robot to combat the Pink Mafia and the Franken organization.

Decades have passed since Shotaro Kaneda and Tetsujin 28 protected the world but evil continues to strike. It's time for a new hero and a new robot, Tetsujin 28 FX, to protect the world. Masato Kaneda returns after mysterious vanishing a year ago to take up the reins of protecting the Earth along with his family and friends from the diabolical Neo Black Gang. With upgrades for Tetsujin 28 FX from Masato's brilliant mother Yoko, along with Shotaro and the original Tetsujin 28 occasionally leaping in to help, can they stop the Neo Black Gang and all the other villains and rogue robots?!.—Discotek Media
