The Brain (full name: Yo-yo with a Brain) by Yomega is a yo-yo with a centrifugal clutch, which makes it return to the thrower's hand automatically when the yo-yo starts to lose spin. It is also the very first yo-yo to feature an auto-return clutch system. This yo-yo is great for beginners, as it helps the user to develop a strong, hard throw and to get a good grasp on the sleeper. It was even licensed to Bandai for the Hyper Yo-Yo line in 1997 as the Hyper Brain (Japanese: ハイパーブレイン), and on April 13th, 2013 as the Wild Claw (Japanese: ワイルドクロー).
