Jail Jormungand Jerk Unite (ジェイルヨルムンガンド・ジャーク・ユナイト, Jeiru Yorumungando Jāku Yunaito) is a Balance Type Beyblade that's a part of the Burst System as well as the Dual Layer System. As an anime-exclusive Beyblade, it was never released. It's owned by Rickson Clay.
Energy Layer - Jail Jormungand
Main article: Energy Layer - Jail Jormungand
Takara Tomy's Jail Jormungand 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 namesake; Jörmungandr, the Midgard Serpent of Norse Mythology.
While Jail Jormungand has a well-balanced and Defensive-looking shape that makes it appear to be good for Stamina and Defense Combinations, 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 - Jerk
Main article: Forge Disc - Jerk
Jerkis a round, thick and symmetrical Forge Disc that features a round perimeter made of soft plastic that's attached to the Forge Disc via screws, akin to Magnum and Polish. The soft plastic perimeter features two shield-like bumpers that are placed behind the Forge Disc's prongs. Unlike most Forge Discs, Jerk features a "Bound Defense" gimmick; in this case, the bumpers are designed to push inwards.
Upon impact, during Disc-to-Layer contact, the bumpers will theoretically bend inwards to absorb the shock of the impact and reduce recoil. In practice, this gimmick is rather dysfunctional. First, due to how rare Disc-to-Layer contact occurs, Jerk will rarely make contact with the opponent. Second, Jerk is rather hollow, creating poor Stamina despite the Forge Disc being round in shape. Lastly, the soft plastic bumpers hardly have any flexibility. This, combined with the Forge Disc's short distance between the stadium floor makes Jerk unsuitable for Defense and Stamina Combinations.
Performance Tip - Unite
Main article: Performance Tip - Unite
Unite features a flat rubber tip with a sharp plastic tip in the center, akin to the Coated Sharp Performance Tip of Metal Fight Beyblade, that sits at the standard height. When launched straight down into the stadium, the sharp tip in the center will keep the Beyblade stable and still in the center, preventing Stamina loss.
When a mint condition Unite is either knocked off balance by an opponent or launched at an angle, the rubber will make contact with the stadium, creating an aggressive movement pattern with speeds similar to Xtreme. However this aggressive movement is somewhat unreliable as the sharp center can slow it down in the center of the stadium or stop the movement entirely.
When worn however, instead of creating aggressive movement when struck, the rubber will instead act as brakes against a Knock-Out, at the cost of Stamina, before going back to the center of the Stadium due to the sharp tip.
