Spryzen S2 Knuckle Unite, known as Storm Spriggan Knuckle Unite (ストームスプリガン・ナックル・ユナイト, Sutōmu Supurigan Nakkuru Yunaito) in Japan, is a Balance Type Beyblade released as part of the Burst System as well as the Dual Layer System. It was released as a Starter in Japan on April 2nd, 2016 for 1300円 and was later released in western countries as a Starter Pack.

Energy Layer - Spryzen S2

Main article: Energy Layer - Spryzen S2
Spryzen S2 is an overall elliptical Energy Layer designed for Balance, which somewhat resembles its predecessor, Spryzen. In the center of the Layer is a beast looking to the right, meant to represent its Japanese namesake; the spriggan, a legendary beast of Cornish Faery Lore.

The perimeter of Spryzen S2 has two main contact points made of colored plastic that also matches the weapon the Layer's beast wields; an axe, which are each followed by a similar-looking blade made of clear plastic, and a square-shaped protrusion that also serves as a location for the Layer's screws. While such an aggressive design might imply high Attack potential, the Japanese release of Storm Spriggan is made useless by its teeth, which are smaller than the teeth of Chaos, which perform poorly in battle, as the teeth of Storm Spriggan are unable to withstand the recoil the aggressive shape of the Layer creates during head-on collisions with the opponent's Layer, causing it to Burst and even Self-Burst very easily.

Forge Disc - Knuckle

Main article: Forge Disc - Knuckle
Knuckle is a circular Forge Disc with six notches around the perimeter and four holes near the center of the Forge Disc. The letter "K" is written on its prongs for easy differentiation from other Forge Discs. Due to the holes in the Disc, Most of the weight of Knuckle is focused around its perimeter giving it high Outward Weight Distribution which results in excellent Stamina properties. However, it lags behind other Forge Discs like Spread and Gravity in terms of Stamina potential.

Although, one advantage Knuckle holds over the aforementioned Forge Discs is increased Burst resistance which only falls behind Down and Armed, both of which suffer from scraping issues and low Stamina respectively. Due to its good Stamina, decent weight and high Burst resistance, Knuckle was once an excellent Forge Disc for all kinds of Combinations. However, Knuckle has one major weakness, the protrusions nullify Life After Death potential which is detrimental in the current Life After Death centered metagame.

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 KO, at the cost of Stamina, before going back to the center of the Stadium due to the sharp tip.
