Infinite-L (無限 L, Mugen L) is a Performance Tip released as part of the Burst System as well as the Cho-Z Layer System. It debuted with the release of the B-126 Cho-Z Musou Beystadium on October 20th, 2018.
Infinite-L, unlike other Performance Tips, is not compatible with a Forge Disc, Right-Spin Layer or Launcher as the weight and prongs of a Forge Disc have been integrated directly into Infinite-L, the thickness of the left 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 Infinite Beystadium it comes with.
Infinite-L’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 Cho-Z Musou Beystadium and keeps the Infinite-L 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 Infinite-L Beyblade back to the spinning center and the heavy weight resists Knock-Outs.
Furthermore, the spring of Infinite-L 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.
Since Infinite-L cannot be used with a Launcher, it cannot be used in tournaments, making it competitively worthless.
However, Infinite-L’s worth lies within how useful the Cho-Z Musou Stadium is to a blader, thus it is completely up to the buyer’s jurisdiction on whether or not to purchase Infinite-L.
