Shieldon is one of Space Empire Zangyack's Action Commanders.
He is an Action Commander whose forearms can interlock to form Thick Face Shield, giving him the greatest defense ability among the Zangyack forces. This leads Doc to develop the Gokai Galleon Buster to harness the Great Power of the Ohrangers, allowing the Gokaigers to destroy Shieldon's Thick Face Shield and then destroy him with Hurricane Gokaioh.
Super Hero Taisen
He later appeared as one of the many monsters in the Dai-Zangyack army, which eventually fought against an army of Super Sentai and Kamen Riders.
