|This article is about a/an leader in Kamen Rider OOO.|
The Boss (首領 Shuryō), later revealed to be the Shocker Leader (ショッカー首領 Shokkā Shuryō, lit. Shocker Boss), was the leader of the 6 Greeeds, and was able to transform into OOOOOO (ヘキサオース Hekisaōsu, lit. Hexa OOO).
It was later revealed that this Shocker Leader was only a character in Eiji's dream.
As a counterpart in Eiji Hino's dream, this Shocker Leader was the incarnation of the Great Leader of Shocker appeared in OOO, Den-O, All Riders: Let's Go Kamen Riders. Although the Rock Great Leader was defeated by the All Rider Break, the spirit of Shocker Leader survived. He reformed the organization and hijacked Kougami Foundation. Using Cell Medals kept in the foundation, Shocker Leader created the 6 Greeeds of evil organizations. He later sent the Greeeds to attack Kamen Rider OOO in order to obtain the OOO Driver.
The OOO Driver was later analysed by the scientists, and successfully created a 6-slot driver. Shocker Leader, now a skeleton, used the driver and transformed into OOOOOO. He then battled Kamen Rider OOO Putotyra Combo and Riderman, and easily defeated them. Shocker Leader then shown the ability to breakdown machines. This ability was specifically effective on cyborgs, and thus successfully disarmed Riderman. However, a man with red mask suddenly broke in and damaged Shocker Leader. The man then team up with OOO and Riderman, and... the dream ends.
