Kamen Rider Bravo Durian Arms gets turned into Kamen Rider Bravo King Durian Arms by an evil Helheim stem which popped out of nowhere.
As per the CSM Lockseed Charmant Set, the Lock Seed used will be called King Durian Lock Seed but with the same Lock Seed Designation of "L.S.-12" as the original Durian Lock Seed. The Faceplate will also be a bit different. When used the Sengoku Driver will shout out "King Durian Arms! Mister Violence" (normal Durian voice "Durian Arms! Mister Dangerous!").
It's not known if we will ever get to see Oren using it for a Transformation Sequence.
Kamen Rider Gridon Lychee Arms is going to be the new form used by Jonouchi in the Spin-off. The Head design looks new... But guess what! That sword is the repaint of Lord Baron's sword.
As per the CSM Lockseed Charmant Set, the Lychee Lock Seed will be designated as "L.S.-14", same as Donguri Lock Seed. The Faceplate will also be a bit different in color scheme. When used with the Sengoku Driver will shout out "Lychee Arms! You are the Hero". And that's from where we get the title of the Theme Song!
Jonouchi will use this Lock Seed to fight against Kamen Rider Bravo King Durian Arms. By the way, the above Lock Seed is still the Donguri Lock Seed.
Originally planned to be an Stage Show exclusive Rider, then making on-screen appearance in Zi-O's movie, now Takatora Nii-san will actually show us transform into Kamen Rider Zangetsu Kachidoki Arms with Shin Kachidoki Lock Seed designated as "S.K.L.S."!
