Zyuden Sentai Kyoryuger was Toei Company’s 37th entry in its long-running Super Sentai Series. It aired from February 17th 2013 to February 9th 2014 for 49 episodes.
Long ago in the time of dinosaurs, the Deboth Army invades Earth to the point of the extinction of the dinosaurs but they were defeated by Wise God Torin and the Zyudenryu during the first invasion. In the present day, the Deboth Army resurface as they resume their invasion. To counter the revived threat, Torin selects five brave individuals who must defeat their respective Zyudenryu first in order to acquire their powers to become the “People of the Strong Dragons”, the Kyoryugers.
Zyuden Sentai Kyoryuger is the third Sentai series with a dinosaur motif (after Kyōryū Sentai Zyuranger and Bakuryū Sentai Abaranger); this time mixed with electricity and up-tempo musical genres such as Samba. Ryo Ryusei, who portrays Daigo Kiryu, said he will find it difficult to live up to the role as the hero in the series. Yamato Kinjo, who portrays Nobuharu Udo, turns 30 within the year and spoke of how he felt it might be difficult to portray a hero to children so much younger than he is.
Critics have noted a drastic shift in the casting of Kyoryuger. Toei producer Takahito Ōmori commented on the lack of a yellow warrior in the series, something that has not happened since Dengeki Sentai Changeman, by noting that the colour yellow has become associated with females for the modern generation of viewers and thus would not be able to properly portray the brutish strength a male character is capable of portraying to match with the concept that the characters beat their dinosaur partners in battle. Ōmori also stated that they chose to make the blue warrior aged 32 to insert some oyaji gags, while also noting the use of Papaya Suzuki as the ending theme’s choreographer to insert some levity, hot-blooded actor Shinji Yamashita as the red warrior’s father, and the inclusion of Shigeru Chiba as the series’ narrator who gives a high tension style to the show.
