Is Amadam really responsible for the creation of Core Medals, Gaia Memories and the like?
So all the Heisei Monster groups owe their origin to a wizard? I don't know how I feel about linking the mythologies of various other Riders to Wizard's, especially considering the quality of the show, but it's an interesting concept. And I like how Amadam empathized how he created the Kamen Riders since he created monsters, what with how integrally connected a Rider and his monster group tend to be.
I was wondering from where this was even coming from, considering how it was mentioned in another post too, but I just noticed that Tv Nihon's version of the episode was out. Anyway, I believe their translation of some of Amadam's dialogue in the battle changes the meaning of his words.
In Tv Nihon's episode, Amadam's lines are
"That's why your powers are also ours!
"The source of the 13' Kamen Riders powers... is the Cross of Fire within me."
I think the way they translated that line changes a lot of the meaning there. For comparison, here are OT's
"That is why your powers will become mine!"
"And the source of you 13 Riders, the Cross of Fire, is within my grasp!"
In TVN's, he's claiming that he's the source of the 13 Riders' powers, the Cross of Fire. In OT's, he's just saying that saying that he's obtaining that Cross of Fire
now by stealing their power (because both of their powers come from the same source).
I do believe OT's translations are more accurate here. Regarding the first line, the original Japanese sentence uses "tonaru", which means "to become". He isn't saying that their power
is his, he's saying that their power will
become his. Regarding the second line, the original statement didn't separate "source of" from "the Cross of Fire" like Tv Nihon did.
13人の仮面ライダーの力の源クロス・オブ・ファイヤーが私の中にある。
"The source of the power of the 13 Kamen Riders, the Cross of Fire, is in my body."
So, Overtime's seems like the correct one there to me. Amadam never claims to be the original source of Riders and monsters' power. He wanted to obtain the Cross of Fire
by stealing the powers of the Riders. He could do that because his power was like theirs, and came from the same source, but that doesn't mean he was the Cross of Fire itself.
On the other hand, Overtime's translation attempts to imply that the Kuuga receiving the FFR here is Onodera (With a "not again!" line), which seems wrong and wasn't implied in the original dialogue. Tv Nihon went with a generic "This is..." which is much more appropriate.
Who is Amadam? How did he get here?
He's an Ancient Wizard who was sealed in that magic stone for his crimes. Episode 53 even shows him using the Rider rings. He wanted to obtain the "Cross of Fire", which is apparently the original source of the powers of all Riders and monsters, and also wanted to break free from that world and send the monsters back to Earth to have his vengeance.
He let the kids escape with the rings, but forced them to fight, exactly to see if they could open a portal to outside with the Rider Rings, that he could use for his plans afterwards. After they did just that, he captured the kids and rings and tried to force them to open the portal again to break free with the monsters and have his revenge against the world.
