Suika Arms

"Suika Arms: Odama Big Bang!"

- Transformation announcement

Suika Arms (スイカアームズ) is an alternate mecha-like watermelon-based armored Japanese Samurai form of Armored Riders using the Suika Lockseed that bears the Suika Head (スイカヘッド) helmet with an unspecified visor. It can also be deployed unmanned.

Suika Arms is the most massive Arms Change, and it shows by having the most monstrous punching and kicking power once in Yoroi Mode. Consequentially, it also has the worst jumping height in all of Rider history, and any Rider can practically outrun it. Though this is rendered moot thanks to Odama Mode and Gyro Mode. Also, after a utilization, the Suika Lockseed's color becomes grey, indicating that its energy is low and needs time to recharge back to its green color before it can be used again.
