Roktavor, known as Ragnaruk (ラグナルク, Ragunaruku) in Japan, is an Energy Layer released as part of the Burst System. It debuted with the release of the B-03 Starter Ragnaruk Heavy Survive on July 18th, 2015. It later debuted in western countries with the release of the Nepstrius & Roktavor Dual Pack.


Roktavor is a rugged looking Energy Layer that bears a striking resemblance to Seaborg's Whale Attacker, featuring two flat, blunt protrusions with smaller, pointier trailing edges. Unlike most other Energy Layers that incorporate some sort of slope or relief, Roktavor has a nearly-uniform thickness throughout the Layer. The majority of Roktavor's weight is packed behind its two primary contact points, which, coupled with the shape of these protrusions, provide the Layer with a considerable amount of Burst Attack. However, these same features also subject Roktavor to large amounts of rotational recoil during a collision as well. As Ragnaruk has only three average sized teeth and one small tooth, is is unable to handle its own recoil and tends to Burst quite often, making it practically nonviable in competitive play.

Use in Burst Attack Combinations

Though outclassed by Valkyrie, Ragnaruk can be used in the Burst Attack Combination Ragnaruk Armed Revolve. This combo combines Ragnaruk's moderate Burst Attack with Armed's ability to reduce the chance of the combo Self-Bursting. While inconsistent at best, it can be used to defeat Stationary Combinations with particularly poor Burst Defense such as Deathscyther Heavy Revolve.


Despite its potential in Attack Combinations, Ragnaruk suffers from having poor Burst resistance, resulting in a number of Self-Bursts when attacking.

As such, Ragnaruk is recommended for collection purposes only.

Differences in the Hasbro Version

Like all other Hasbro Energy Layers, Hasbro's Roktavor is made of a softer plastic that causes it to have lower Stamina than Takara Tomy's Ragnaruk. However, despite this, the steep slopes of Roktavor make it much less likely to Burst than its Takara Tomy counterpart, meaning that it can take full advantage of its aggressive shape to exhibit excellent performance in Burst Attack while also having moderate KO Attack. Due to its steep slopes and aggressive shape, Roktavor can be used in Attack Combinations with success.

Use in KO Attack Combinations

Roktavor can be put to use on the KO Attack Combinations Roktavor Heavy/Gravity/Knuckle/Spread/Down Variable/Xtreme. Although Xtreme and Variable are preferred for Layers excelling in KO Attack like Xcalius, their high speed can provide powerful hits which combined with the aggressive shape of Roktavor can Burst the opponent. The high speed of Variable/Xtreme also increase the chances of a KO. While using a heavier Disc might provide powerful hits, using a lighter Disc can reduce the risks of Self-Bursting.

Use in Mixed Attack Combinations

Roktavor can be used in the Mixed Attack Combination Roktavor Heavy/Gravity/Knuckle/Spread/Down Accel/Zephyr. Although this combo may not possess the same KO potential and high speed as Xtreme/Variable variants, it is easier to control and the higher stamina of Accel/Zephyr provides more hits, increasing the chances of a Burst or Out Spin if it fails to KO the opponent.

Use in Stationary Attack Combinations

Due to having excellent Burst Attack because of its aggressive shape, Roktavor can be used on the Stationary Attack Combination Roktavor Heavy/Down/Knuckle/Spread/Gravity Survive/Press/Defense/Needle. This combo can Burst opponents as consistently as Accel/Zephyr/Xtreme/Variable variants while having less chances of Self-KOing than Accel/Zephyr/Xtreme/Variable variants. In addition to this, the aggressive shape of Roktavor can Burst other Attack-oriented Layers on a Mobile or Stationary Combinations.

Overall (Hasbro)

Roktavor was a Top-Tier and commonly available Energy Layer for Attack Combinations. However, with the release of the SwitchStrike/God Layer System, specifically Legend Spryzen S3, Roktavor has become outclassed.

As such, Roktavor is not a must have but is instead a welcome addition to a blader's collection.
