Forever King 2018 (フォーエバー・キング2018 Fōebā Kingu Nisen-jūhachi) is the sixteenth episode of Kamen Rider Zi-O. It features the debut of Zi-O DecadeArmor Ex-Aid Form, Geiz Ex-AidArmor and Decade Wizard. Kamen Rider Woz makes a brief appearance in this episode.

This episode is accompanied by the final episode of Kamen Rider Zi-O: Supplementary Plan web series, Supplementary Plan Forever (Part II).


"If you throw away that belt, then you'll never become the demonic king... You can change the future..." Sougo after hearing the words of Ohma Zi-O was faced with an excruciating decision. Strangely the DaiMajin that exists to destroy the world still exists. After witnessing the crisis that Geiz is facing, Sougo makes his decision. What will Sougo choose to do?!


"According to this book, average high schooler Sougo Tokiwa embarks on a path which leads him to become the demonic king of time, Ohma Zi-O. After being sent to the future by the Destroyer of Worlds, Tsukasa Kadoya, he is faced with the reality that he is indeed Ohma Zi-O. In an effort to alter the future, he forsakes his belt. That is all that is written as of this point..."
