Power Grip is a Tune-Up Gear introduced in the Cross Fight B-Daman toyline.
This adds significant power to the B-Daman. It has three ways to hold it and it can turn for a sideways grip. The parts can be removed so that you can invert it and attach it to B-Daman with a different kind of trigger. This grip is mainly used on Thunder Bison and provides a comfortable grip on the trigger by holding the B-Daman with one hand and holding the grip with the other. There is also a small wheel on the bottom for a smoother shot. This grip works by thrusting the grip forward to fire the B-Daman.
