The first Flying Smash was created from Reika Kine, the co-owner of a ferry with her husband. She was kidnapped by Faust and turned into the Flying Smash before being let loose. She was defeated by Build GorillaMond, reverting her back to her human form.
A second Flying Smash was created when Touto Institute of Advanced Matter Physics researcher and Faust agent Shingo Kuwata poured an unpurified Fullbottle onto himself to become and Smash and fight Build in order to lure him away from the Institute. He was defeated by Build LionCleaner and had his essence absorbed into an empty Fullbottle.
