It was released as a Booster in Japan on January 21st, 2017 for 972円 and was later released in western countries as a part of the Jormuntor J2 & Fengriff F2 Dual Pack for CAD$19.99 in Canada, USD$14.99 in the United States, and AUD$24.99 in Australia.
Energy Layer - Jormuntor J2
Main article: Energy Layer - Jormuntor J2
Jormuntor J2 is a Stamina Type Energy Layer that has a mostly circular shape composed of two slopes with slight ridges and two small gaps or protrusions at the end of the slopes. The center of the Layer depicts two serpents spitting fire, meant to represent the Layer's Japanese namesake; Jörmungandr, the Midgard Serpent of Norse Mythology.
While Jormuntor J2 has a well-balanced and defensive-looking shape that makes it appear to be good for Stamina and Defense Combinations, for the Takara Tomy release of Jail Jormungand, it only has one good tooth, with the rest of its teeth being sub-par at best. This in turn, makes Jail Jormungand an ultimately useless Layer for competitive play.
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.
- Jormuntor's Japanese name, Jail Jormungand, is based from "Jail", a synonym for incarceration, and the world serpent Jörmungandr from Norse mythology.
