It's not even that they so much are literally monsters, it's that Rider powers always come from either the same source as the monsters of the series, or from something very related to them. Wizard is powered by his Phantom, Fourze uses Astro Energy, OOO uses Core Medals, Decade was actually a villain the whole time , Kiva was part Fangire, the Naturals designed the Zecters, SmartBrain's Rider Gear can't be used by people who lack Orphenoch DNA, Ryuki contracted with a monster for power, etc, all the way back to Ichigou being some dude who was turned into Hopper Kaijin. The Rider is linked to his foes, they are mirrors of each other. It's thematic!meljta wrote:This is true, all are monsters who decide to fight by humans, and not by their own species,
Kamen Rider is about the struggle against the darkness within the human heart. It always has been.
