Using my awesome skillz:
- Double "Double!"
"Cyclone!:
"Joker!"
~Cyclone Henshin~
~Joker Henshin~
- Kuuga (Unchanged) "Kuuga!"
~Mighty Form Henshin~
~Dragon Form Henshin~
~Pegasus Form Henshin~
~Titan Form Henshin~
- Ryuki "Ryuki!"
~Henshin~
"Advent!"
~Dragreder Sound~ (New Sound)
"Final Vent!"
~Final Attack Sound~ (New Sound)
- Faiz (Unchanged) "Faiz!"
"Beep, beep, beep! Standing By!"
~Stand By Sound~
"Complete!"
~Henshin Sound~
(There's some Kanji here that I can't read, but I'm assume it is the same as the original Candy Toy)
- Hibiki (Unchanged) "Hibiki!"
~Henshin Sound~
~Whistle Sound~
~Ibuki Attack~
~Guitar Sound~
~Todoroki Attack~
(Again, Kanji I can't read, assuming it is the same as the original Candy Toy)
- Kabuto "Kabuto!"
~Henshin Sound~
"Cast Off!"
~Cast Off Sound~
"One! Two! Three!"
"Rider Kick!"
(Mostly unchanged, but I think this one put "One, Two, Three" together into one click as opposed to individual pushes. No idea whether "Henshin!" or "Change Beetle!" were added to the other sounds.)
- Den-O (Unchanged) "Den-O!"
~Stand By Sound~
"Sword Form!"
~Henshin Sound~
- Kiva "Kiva!"
"Gabu!"
~Henshin Sound~
"Wake Up!" (New Sound)
~Fuestle Sound~
(Wake Up! was added as a fifth sound. The original Gashapon only had 4.)
- OOO "Ozu!"
~Medal Scan Sound~
"Kamen Rider Ozu!"
"Kore de Kimarida!" ("It's decided!" Google was trying to give me "The deal is made!" which I guess works out for someone like Ozu, but I'm going with "It's decided!" for now. I am assuming it will be his "catchphrase". No idea what else the Medal Scan sound will be, but it doesn't look like it will say TaToBa! or anything like that.)
I'll update this as I make out the Kanji. Also, I have no idea whether this Double will differ from the one in Gashapon Set 5. I doubt it will be any different. It looks like Kiva has finally redeemed himself for me.
