A short-lived and hard-to-find Japan-only version of the Duncan fixed, wooden axle ProFly, rebranded for Bandai's Hyper Yo-Yo series as the Hyperloop Fly. As a Hyper Yo-Yo, you could use it to attain Hyper Yo-Yo certification in Japan. The shape is identical to the Playmaxx ProYo II GT, the first generation model of this long-lived yo-yo. And just like the ProYo II GT, it has a take-apart design with a replaceable wooden axle.
