Engery Layer - Storm Spriggan
Main article: Energy Layer - Storm Spriggan Takara Tomy's Storm Spriggan is a rather elliptical Energy Layer, and somewhat resembles its predecessor, Spriggan. This Layer has two main contact points protruding from the under layer at the extremities of its oval, which are each followed by a similar-looking blade composed of the polycarbonate over layer and a square-shaped projection that also serves as a location for the screws. While such an aggressive design might indicate potential usefulness in Attack, the Energy Layer is made useless by its teeth, which are smaller than the teeth of Chaos, which are reputed to perform poorly. As the teeth on Storm Spriggan are completely unfit to manage the rotational recoil the aggressive shape of the Layer subjects them to during collisions, it Bursts itself very easily and should not be considered for use in competitive play.
Performance Tip - Mugen
Main article: Performance Tip - Mugen Mugen, unlike other Performance Tips, is not compatible with a Forge Disc, Left-Spin Layer or Launcher as the weight and prongs of a Forge Disc have been integrated directly into Mugen, the thickness of the right sides of the prongs and the width of the prongs prevents a launcher from fitting inside. This is due to the fact that the Tip must be used with the Mugen and/or Musou Beystadiums.
Mugen’s bottom features a wide, low angled cone tip, akin to a larger Wide Defense from Metal Fight Beyblade, that is magnetized, akin to Prototype Nemesis from Metal Fight Beyblade. The magnetic tip connects with the center of the Mugen and/or Musou Beystadiums and keeps the Mugen Beyblade fixed in place and spins with the stadium’s motorized center, when knocked off of its perch, the wide cone tip creates a stable, Stamina-conserving spin and brings the Mugen Beyblade back to the spinning center and the heavy weight resists KOs.
Furthermore, the spring of Mugen is much stronger than that of other Performance Tips which increases the Burst resistance of the Layer it’s paired with. Such features are meant to simulate a strong Stationary Defense/Stamina/Attack Type depending on the Layer used in order to practice Banking Shoots with Attack Combinations or test a Combination’s Burst and/or KO resistance.
