Jormuntor J2 Infinity Cycle, known in Japan as Jail Jormungand Infinity Cycle (ジェイルヨルムンガンド・インフィニティ・サイクル, Jeiru Yorumungando Infiniti Saikuru) is a Stamina Type released as part of the Burst System as well as the Dual Layer System. It was released as a Booster in Japan on January 21st, 2017 for 972円 and was later released in western countries as part of the Jormuntor J2 & Fengriff F2 Dual Pack.

Energy Layer - Jormuntor J2

Main article: Energy Layer - Jormuntor J2
Jormuntor J2 has a mostly circular shape composed of two slopes with slight ridges and two small gaps/protrusions at the end of the slopes. The center part of the bey shows two serpents breathing fire. While this well-balanced and defensive-looking shape appears to be a good Layer, a quick glance underneath shows that the Layer only has one good tooth, with the rest being subpar at best. This unfortunate fact makes Jail Jormungand an ultimately useless Layer.

The Layer’s spirit is based on Jörmungandr, also known as the Midgard Serpent, from Norse mythology. Jörmungandr was one of the three children of Loki, and grew so large that it encompassed the earth and swallowed its tail.

Forge Disc - Infinity

Infinity features a round, thick, sharp edged and warped design meant to recreate the look of a Mobius Strip. Like Ring, almost all of Infinity's weight is focused on the perimeter creating a high Outward Weight Distribution and Flywheel Effect for Stamina Combinations and the round design allows for some Life After Death. However, like Ring, the high Outward Weight Distribution increases the risk of Bursts as the Disc and Performance Tip will resist changes in spin speed while the Layer is more likely to stop, leading to teeth skipping and Bursts.

Performance Tip - Cycle

Main article: Performance Tip - Cycle
Cycle features a low angle cone tip akin to Survive, but differs by having a free-spinning disc above the tip, akin to Metal Fight Beyblade's Eternal Defense 145, the housing of which also extends down around the tip creating a free spinning ring like an inverse Gyro. In theory, the disc is meant to contact the stadium floor when the Beyblade is off balance and bring it back upright while minimizing Stamina loss due to the disc's free spinning nature. In practice however, the disc does little to stabilize a Combination and causes Stamina loss despite the free spinning nature as pressure at an angle, which is created by a listing Beyblade, creates resistance and makes the disc lock up. While the secondary point of contact created by the disc can create some level of KO resistance equal to Orbit, the resistance caused by the disc locking up increases the risk of Bursts, unlike Orbit which increases Burst resistance.
