Dark Gasher CH120SF is a Balance-Type Beyblade from the Metal Fusion series, known for its unique CH120 Spin Track, which allows its height to be adjusted mid-battle (from 120mm to 145mm) for varied strategies, paired with a Semi-Flat (SF) Performance Tip that balances speed, defense, and stamina, making it versatile but compromising peak performance in any one area. It's a repaint of Mad Cancer (or Dark Cancer), featuring the crab motif and owned by Tetsuya Watarigani in the anime, making its key feature the tactical height change.}
