The Dai-Shocker Scientists are white masked researchers with black skeleton markings, wearing white lab coats, shirts and pants, alongside with white gloves covering their hands.
A notable Dai-Shocker Scientist was an alternate version of the Destron Scientist Joji Yuki. He was involved in the production of the Decadriver and Ride Booker, as well as the Diendriver. However, Yuki was punished on the orders of the Great Leader of Dai-Shocker Tsukasa Kadoya for treason, having his right arm removed. But Yuki survived and ran away from Dai-Shocker, making him a wanted man in the World of Decade.
Like the scientists of the original Shocker, Dai-Shocker Scientists performed remodelling surgery on humans to turn them into kaijin. In the World of Amazon, Masahiko Okamura was taken to undergo remodelling surgery for his services to Dai-Shocker. A pair of Dai-Shocker Scientists were to perform the operation, with one of them suggesting they make him a sea cucumber kaijin. However, they were interrupted by Tsukasa Kadoya and Yusuke Onodera, who were disguised as Dai-Shocker Combatmen, proceeding to knock out the scientists and rescue Masahiko.
