Jerk (ジャーク, Jāku) is a Forge Disc released as part of the Burst System. It debuted with the release of the B-61 Random Booster Vol. 4 Quad Quetzalcoatl.J.P on October 22nd, 2016. It later debuted in western countries with the release of the Starter Pack Quetziko Q2 Jerk Press.
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.
The design of the Burst System makes Disc-to-Layer contact between Jerk and the opponent's Layer rare, the hollow design of the soft plastic heavily reduces Stamina, the thick shape of the Forge Disc makes scraping common, its weight is too light to be used in Defense Combinations, and the force needed to make its Bound Defense gimmick work is simply too high to happen in battle, making Jerk completely worthless.
As such, unless one prefers to use Jerk, it is recommended for collection purposes only.
