|This article is about a/an temporary villain in Kamen Rider Build.|
Kyoichi Shimizu (志水恭一 Shimizu Kyōichi) was one of the victims of Faust's experiments who was turned into the Strong Smash (ストロングスマッシュ Sutorongu Sumasshu). His Smash essence was used as the basis for the Gorilla Fullbottle. He later uses the Kuwagata Fullbottle to become the Stag Lost Smash (スタッグロストスマッシュ Sutaggu Rosuto Sumasshu)
The Strong Smash appeared and attacked Sento Kiryu and Ryuga, grabbing Ryuga and trying to take him away, presumably back to the facility. Ryuga fought back without success, but Sento transformed into Kamen Rider Build RabbitTank and fought it. He briefly took HarinezumiTank before returning to RabbitTank and defeating the Smash with Vortech Finish, extracting the Smash essence with a blank Fullbottle. Questioned by Ryuga, Shimizu claimed to remember nothing, escaping into some tall grass as a squad of Touto Guardians arrived.
The Bottle was later purified into the Gorilla Fullbottle.
Later, presumably under Evolto command, Shimizu encounter Sento and by using Kuwagata Lost Fullbottle, he becomes Kuwagata Lost Smash and attacks Sento. Sento later cancels his transformation using Build Genius form. However, just before Shimizu leaks more info about Katsuragi Shinobu, Evolto kills him by injecting Shimizu with a lethal dose of poison that disintegrates him.
