Kilardoian is a robotic alien from the planet Kilardo and an agent of the Warp Monarch. He is an antagonist in Chouseishin Gransazer.
Kilardoian was sent to Earth to destroy the crystal recorder in the possession of the 18 year old Nobel Prize winner Professor Aya Stacey. He assumed the form of a man in black to better blend in to society.
Despite the efforts of the Gransazers, Kilardoian managed to accomplish his mission. He then turned his attention to Aya and Gou and attempted to kill both of them. However, Sazer Tragos and Sazer Dail intervene and attack him.
Tragos manages to deliver a crippling blow to Kilardoian, allowing Dail to finish him off.
