The Slow Motion Burstis a move or technique only a counter clockwise or left-spinning beyblade can master. When it is almost out of stamina and spin power, when hit by a clockwise spinning bey, it speeds up and can burst an opponent easily. In the video made by Drago Galaxy, you can see that Drain Fafnir got a Burst on Legend Spriggan The Rubber on Fafnir came in contact, and Fafnir got so much spin that the grip from the rubber on Drain Fafnir made Legend Spriggan's teeth skip all the way in one hit, which also made Fafnir come out of the stadium, but was still spinning on the floor. This move can be used with Drain Fafnir, Geist Fafnir and Wizard Fafnir. This move can also help you get a last second burst as seen in this video made by u/Slash-Valkrie:  This video is also proof that not only beyblades with rubber can use this move.
