Kamen Rider

Blade vs. Blade is a Hyper Battle Video, wherein a Trial-series cyborg pretends to be Kenzaki, who quickly discovers the fraud and fights him. During their battle, the other Riders bicker humorously about which Blade is the fake, which constantly results in their attacking the real Kenzaki. As with all Hyper Battle Videos, this serves to explain in detail the Rider's various powers and abilities.
