The Bandai Hyper Yo-Yo Yomega Stealth Brain.

The Yomega Stealth Brain was licensed by Bandai of Japan for their Hyper Yo-Yo series. This model was just one of many others from Yomega, Duncan, and YoYoFactory that helped fuel the incredible yo-yo craze of the late 1990s.

The U.S. version, known as the Yomega Saber Wing Brain, and the Japanese version, known as the Yomega Stealth Brain, were identical models. Both models were also cousins to the Yomega Brain and Yomega Hyper Brain, also transaxle yo-yo models, but in a butterfly shape (Yomega called it a "saber shape"). The primary differences between them often involved packaging, naming, and branding, rather than significant variations in design or performance.

The model in this exhibit features a saber shape in an all clear body, black sidecaps with silver printed text, and black brain actuators.

Released in 1997 at the start of Bandai's first Hyper Yo-Yo series, the Stealth Brain was a popular yo-yo in Japan for doing tricks during the yo-yo boom of 1997 to about 2001. Since then, there have been three more Hyper Yo-Yo series released in Japan: 2003, 2010, and 2024. According to Bandai, the legendary "Hyper Yo-Yo" series has sold more than 30 million units worldwide.

From yoyorewindstore.com:
"Originally released in 1997 during the first Hyper Yo-Yo Boom, this now nostalgic model featured a "Brain" response system.

This is an original Hyper Yo-Yo Stealth Brain, which was an OEM version of the Yomega Saber Wing Brain released in USA back in the late 1990's. This model featured a "Brain" device that initiated an auto-return when the yo-yo slows down enough.

Today (2024), this model would not be considered a beginner yo-yo. Although it may have been marketed as such originally. Compared to modern yo-yos, this one is very difficult to control, and nowadays it would be considered a challenge to play with. It is more suited for a veteran player or as a collector model. To play with this yo-yo may require frequent maintenance that requires specialized knowledge.

The string on this model was 100% cotton, which was not very reliable and prone to breakage. A type 6 (50% cotton/50% polyester) string is best for this yo-yo nowadays."
