Kouji Sakuraba acted as the designated Webdiver for Sharkon, a Web Knight that transformed from a hovercraft into a shark-based combat form. Sharkon possessed aquatic mobility and employed a pressurized water cannon attack named the Aqua Tornado. While Sharkon remained under Deletloss's control, Kouji underwent brainwashing alongside the Web Knight. This conditioning enabled Sharkon to emit sonic waves that agitated marine life and triggered aggressive behavior.
