The Jimber Arms (ジンバーアームズ Jinbā Āmuzu) are upgraded, jinbaori-themed versions of a default form of Armored Riders. Accessed through attaching a Genesis Core to the left side of a Sengoku Driver to use an Energy Lockseed alongside a normal Lockseed, the Riders in Jimber forms wear different helmets with different visors. While it is mostly used by Armored Rider Gaim, it can also be used by other Riders, provided that the latter has a Genesis Core Unit. Each Jimber form seems to give a special power depending on the Energy Lockseed used: Lemon gives strength, Cherry gives speed, and Peach gives heightened senses; those of other Jimber forms are either unclear or unknown.
