The Zero-G was Yomega's first attempt at creating an offstring yo-yo, and despite the high anticipation for it, the yo-yo was never officially released. It was also Yomega's first attempt at making a yo-yo that has rubber shells.
In a time where many companies are trying to find their way around Playmaxx's Brake Pad patent, others were also trying to bypass Henrys' patent for the removable rubber shells used by yo-yos such as the Viper.
Yomega's solution to this conundrum; don't make the rubber shells removable. This had also solved the problem of working with soft rubber without it flying off of a high-speed spinning yo-yo during play. The Zero-G's shells are built into its plastic hub, thus locking them in place.
Possibly to lower production costs, Yomega used a transaxle sleeve for the Zero-G. Unlike the transaxle used in the venerable Fireball, the Zero-G's own transaxle sleeve was made narrower so that it cannot be interchanged with the former, meaning that it cannot use Raider-sized ball bearings either.
Ultimately, Yomega realized that making open-sourced yo-yos with their parts interchangeable would only help their sales, but not in time for the Zero-G, which was cancelled as a result.
- The presence of Bandai's logo on the hubs shows that the Zero-G was slated to be released as part of the Hyper Yo-Yo range, possibly as Yomega's answer to the Henrys Hyper Viper.
- Its design would eventually be used in the YoTech Super Wing, only it has a ball bearing instead of a transaxle.
