Budou Arms (ブドウアームズ Budou Āmuzu, lit. "Grape Arms") is an alternate grape-based armored Chinese Soldier form of Armored Riders. Accessed through the Budou Lockseed, this form's Arms Weapon is the Budou Ryuhou, while the helmet the Rider wears is the Syoryumen (招龍面 Shōryūmen, lit. "Summoned Dragon Face") with the Ryugan (龍眼 Ryūgan, lit. "Dragon Eye". Doubles as a pun on "Japanese Longan") visor. While it is the default form of Armored Rider Ryugen, it can also be used by other Riders.
