Boom! The Cavities of Ankydon (ドゴォーン！ムシバのアンキドン Dogōn! Mushiba no Ankidon?) is the fifth episode of Zyuden Sentai Kyoryuger. It marks the first appearance of Ramirez and his partner, Zyudenryu Ankydon.
When Debo Batissier causes Ian to get painful tooth cavities, Daigo, Nobuharu, and Amy must figure out how to call upon the power of a new Zyudenryu, Ankydon, while they meet a mysterious man within the Spirit Base.
After getting into a fight with Ian while they and the others are testing the powers of the Zyudenchi, Souji feels he and Ian can not work together. Soon after, the Kyoryugers are alerted to Deboth activity at a pastry shop where everyone is in pain from cavities after eating the shop's cakes. Canderrilla and Luckyuro soon discover this as well, as any plans they have would be to make people unbearably happy, and discover that their cavity-ridden Debo Monster Debo Bathisie is the cause. During the fight, Kyoryu Green and Kyoryu Black's disagreement puts them at a disadvantage, allowing Debo Bathisie to escape. At the same time, a mysterious Zyudenryu emerges while Torin and a mysterious man arrive to the battle. The man is introduced as Ramirez, the partner to the Zyudenryu Ankydon who suddenly went wild. Upon revealing Ankydon to be one of the five missing members of the Ten Great Zyudenryu, Torin believes that Debo Bathisie has caused Ankydon's strange behavior. Despite Ramirez trying to ease the tension between the feuding Kyoryugers, Souji scolds the man's naivete while Ian agrees to help him calm Ankydon. Though Souji speaks ill of Ian after he runs off, Daigo him to reveals that Ramirez is actually a ghost and that Ian has only agreed to help as he noticed this fact as well. Meanwhile, upon revealing to Canderrilla he was not acting on his own accord, Debo Bathisie suddenly goes wild again and transforms. He attacks the city once more before being spotted by Ian who hits the Debo Monster while transforming into Kyoryu Black. However, Kyoryu Black finds his attack on Debo Bathisie's teeth had no effect, but he instead finds himself with painful cavities. Luckily, Souji arrives to protect Kyoryu Black from the Debo Monster's attacks with the others following soon after. The two agree that they should help each other, and they trade Zyudenchi to fight in tandem. Kyoryu Green uses Parasagun to cut away Debo Bathisie's teeth and Kyoryu Black uses Zakutor to finish the attack, freeing him from the painful cavities. Before he can be destroyed, Debo Bathisie uses a Sukusuku Joyro to enlarge, now with a new set of teeth, as Kyoryuzin is formed to fight the Debo Monster. With Torin and Ramirez telling them to board it with the others, Kyoryu Black and Kyoryu Green enter Kyoryuzin so the five Kyoryugers' Brave can enable it to use the Goren Zyudenken sword, destroying Debo Bathisie with the Brave Finish attack. While all of Debo Bathisie's victims are now restored to good health, the group soon discovers that both Debo Bathisie and Ankydon have actually been under the influence of another Debo Monster: Debo Wilson.
