The Stealth Brain is a yo-yo produced by Yomega and released as part of Bandai's Hyper Yo-Yo line in October 1997. It was adapted overseas in North America as the Saber Wing Brain.


The Stealth Brain is a variation of the Hyper Brain featuring the same narrow wing shape as the Stealth Fire, which was released a month prior. Of course, it has an auto-return clutch system, allowing the yo-yo to return to the user's hand on its own when it begins to lose spin. The wing shape also allows players to learn basic string tricks, such as the Elevator.
