Unnamed man was a subject of Faust's experiments, turning into the Needle Smash. His Smash essence was used as the basis for the Harinezumi Full Bottle. An unidentified man was experimented on and turned into the Needle Smash. The Needle Smash was seen on security footage in an unknown context. It later encountered and attacked Sawa Takigawa, an investigating journalist, but was interrupted by Kamen Rider Build and quickly defeated by Rabbit Vortech Break. The Smash essence was absorbed into a blank Full Bottle, leaving the man behind. The Bottle was later purified into the Harinezumi Full Bottle.
