Attention Kamen Rider Zero-One fans! This DX Progrize Hopper Blade is the awesome new weapon that debuts with Metal Cluster Hopper. It's a bright yellow sword designed to look like a Progrise Key, with similar motifs and details that tie into the Zero-One universe. The coolest feature? The nub at the end of the blade can plug into the Attache Calibur's key slot to combine them into an even bigger weapon – just like in the show. Plus, you can scan it with the Zero-One Driver (sold separately) to activate various final attack sounds in both regular and combined modes. The toy comes with 3 LR44 batteries already included, so you can start playing right out of the box. It's made by Bandai, so you know the quality and authenticity are on point. Whether you're a collector of Kamen Rider merchandise or buying it for a young fan who loves to recreate epic battles, this Progrize Hopper Blade adds a lot of play value. It's sturdy, detailed, and captures that tokusatsu flair perfectly. Get ready to shout 'Henshin!' and unleash some Rider moves!
