In 1984, he reprised his role alongside Hiroshi Miyauchi (Kamen Rider V3) and Takehisa Yamaguchi (Riderman) in the TV special Birth of the 10th! Kamen Riders All Together!!, which featured former Super-1 candidate Shun Sugata as Kamen Rider ZX.

Scandal
In 2013, the media had exposed that Shunsuke Takasugi had bilked 50 million yen (about US $450,000) from his fans. He used the influence of his role as Kazuya Oki/Kamen Rider Super-1 to cheat his fans and refused to return them all the money. For example, one of excuses he came up with is that "Super-1's henshin belt was taken by the Yakuza (gangsters) and I need money to get it back." From 2003 to 2012, he bilked 5 people who were big fans of Super-1. Even as he was sued, he refused to appear in court. Due to his dishonesty and currently being missing since January 2017, despite Super-1 going on to make later minor appearances, including in recent crossover movies, Shunsuke Takasugi is unable to reprise his role again.
