|This article is about a/an villain in Kamen Rider Decade.|
Jyumenki Yum Cimil (十面鬼ユム・キミル Jūmenki Yumu Kimiru) is the leader of Geddon and Dai-Shocker's designated ruler of World of Amazon, developing the mindset that Kamen Riders are the enemies of the human race, rather than Geddon.
World of Amazon
He has the GaGa Armlet and seeks Amazon's GiGi Armlet to gain their full power and use the unlimited ancient Inca powers to complete his master plan of converting humans into monsters. He normally resembles a torso attached to a large boulder, but he can also assume a humanoid form adorned with the faces of the ten Heisei Kamen Riders from which he can access their powers and counter any of the ten Heisei Kamen Riders attacks. Though he gains the GiGi Armlet, he loses both it and the GaGa Armlet to the Kamen Riders with Decade Complete Form weakening him with Faiz Blaster Form before Amazon destroys him with the Super Wild Slash.
Let's Go Kamen Riders
Due to a change in history caused by Ankh leaving a O-Medal behind in the year 1971, Shocker achieved its goal of world dominion with the Shocker Greeed and new members from various other groups gathered around Shocker. Yum Cimil, Geddon's representative, was one of the many villains who were part of Shocker's alliance. After the Great Leader of Shocker reveals his true form, he fell to his death during an earthquake along with several other representatives.
Super Hero Taisen
Yum Cimil was revived as part of Dai-Shocker in the "super hero taisen" incident which saw them clash with Dai-Zangyack under Tsukasa Kadoya then joining forces with them under Doktor G and facing off against the combined forces of the Kamen Riders and Super Sentai. He is seen fighting Gosei Red when Decade attacks the Goseigers.
Kamen Rider Taisen
Yum Cimil was resurrected as part of the revived Badan Empire.

- When he possesses both the GiGi and GaGa Armlets, Yum Cimil can draw supreme power from the ancient Inca civilization, allowing him to induce transformation into monsters in humans without the need of cyborg modification by Dai-Shocker scientists.
