Blaze Ragnaruk 4 Flugel (ブレイズラグナルク四フリューゲル, Bureizu Ragunaruku Shi Furyūgeru) is an Stamina Type Beyblade that's a part of the Burst System as well as the God Layer System. As an anime-exclusive Beyblade, it was never released. This combo was used by Rantaro Kiyama whenever he removed the Cross Disc Frame from his Blaze Ragnaruk 4Cross Flugel in the Beyblade Burst Evolution anime.
Energy Layer - Blaze Ragnaruk

Takara Tomy's Blaze Ragnaruk is a round Energy Layer designed for Stamina. Consisting of a small inner layer made of clear plastic and four wings, two of which are small and made of clear plastic and two of which are large are made of colored plastic. The large wings are molded to create the visage of heads to match the anime's rendition of the Layer's beast, a winged demon. The small clear wings are dubbed the "Stamina Wings" and make up the gimmick of this Layer.
In theory, the edges of the wings would extend from their hinges and increase a Beyblade's stamina by increasing the Layer's Outward Weight Distribution (OWD), however in practice the size of the wings are simply too small to cause any noticeable weight shift and thus serve no real purpose.
The compact placement of the wings creates a very round design where any protrusions and gaps from and between the wings are too shallow to create high recoil. The large size of the wings imply high Outward Weight Distribution (OWD) and Stamina potential but in actuality, Blaze Ragnaruk's Stamina is only average. Blaze Ragnaruk features four teeth of tall height giving this Layer high Burst Resistance.
Forge Disc - 4

4, like other even numbered Core Discs, is symmetrical and elliptical in shape in order to facilitate a Disc Frame. Each side features two protrusions, one molded into the shape of a "4" and the other molded into the shape of the Roman Numeral "IV". The protrusions extend further from the center more than other Core Discs which grants 4 high Outward Weight Distribution (OWD) and subsequent Stamina potential. As a Core Disc, 4 is comparatively heavier than regular Forge Discs such as Heavy and Gravity which grants higher Knock-Out Resistance and the ability to facilitate Disc Frames can add characteristics such as Life-After-Death with Cross or Glaive. While 7 has greater Stamina, 4's Stamina is still comparable.
Performance Tip - Flugel
Main article: Performance Tip - Flugel
Flugel features a low angled cone tip that sits at the standard height akin to Survive, but differs by featuring four wings, akin to Metal Fight Beyblade's Down Force 145, that offer Upper Force in Right-Spin and Down Force in Left-Spin.
The cone shape gives Flugel low surface area and friction to conserve Stamina in battle while also providing Stability, giving a Combination resistance against the Layer scraping against the Stadium floor and losing Stamina.
In theory, when used in Right-Spin Combinations, the Upper Force would increase Stamina by generating an air current that "lifts" the Beyblade off of the stadium, effectively reducing the friction between Flugel and the stadium. When used in Left-Spin Combinations, the Down Force generated would push the Beyblade down into the stadium and increase Stability at the cost of Stamina. However in practice, the small size of the wings means that any Upper Force or Down Force generated is minimal with no discernible difference in performance.
- Like its predecessor Raging Roktavor Gravity Revolve, Blaze Ragnaruk is based on the words "Blaze", a large or fierce burning fire, and Ragnarök, a series of future events in Norse mythology, including a great battle, foretold to ultimately result in the death of a number of major figures (including the gods Odin, Thor, Týr, Freyr, Heimdallr, and Loki), followed by various natural disasters occurring, and the subsequent submersion of the world in water. Afterward, the world will resurface anew and fertile, the surviving and returning gods will meet, and the world will be repopulated by two human survivors.
