Yegdrion, known in Japan as Yggdrasil (ユグドラシル, Yugudorashiru), is an Energy Layer released as a part of the Burst System. It debuted with the release of B-31 Starter Yggdrasil Ring Gyro on February 20th, 2016.


Yegdrion is a Stamina Type Energy Layer named after Yggdrasil, the tree of life in Norse mythology, however to represent the anime’s rendition of this Layer’s beast, two dragon heads are present on either side near the center of the Energy layer.

It is a square-shaped energy layer with two Dragon heads and two sloped blades meant to represent dragon claws on each side which make up the primary points of contact of this layer. There are two small notches on either side of the layer giving it a rough perimeter, which may imply high recoil but the protrusions are too shallow and produce only moderate recoil in practice.

Most of the weight of Yegdrion is focused on its perimeter. While this may imply high stamina potential, the square shape and rough perimeter of the layer produces recoil which diminishes the Stamina of the layer in battle, making it outclassed by Energy layers like Deep Chaos and Screw Trident stamina-wise. While the sloped blades may imply destabilizing potential, the angle is too shallow and so they serve no purposes other than creating recoil. The recoil produced by the its shape is very low to be useful for Attack Customizations. Further more, the Takara-Tomy release of Yggdrasil features four teeth of short length which are unable to handle its recoil making it extremely prone to losses by Burst Finish.


Yggdrasil is outclassed for Stamina by many other Layers and incurs self-Burst far too easily. While it can act as a consistent counter against Xcalibur, with the release of the SwitchStrike/God Layer System, that niche use is no longer viable.

As such, Yggdrasil is recommended for collection purposes only.

Differences in the Hasbro Version

The Hasbro release of Yegdrion features moderate slopes, giving it greater burst resistance than its Takara-Tomy counterpart and allowing the layer to withstand its own recoil, however the slopes are weaker than those of layers like Kerbeus, Anubion A2 and Jormuntor J2 making it lag behind these aforementioned layers in terms of burst defense. The high flywheel effect produced by its outward weight distribution makes it one of the best layers available for Stamina Customizations in the Hasbro-Only Format.

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

Use in Stamina Combinations (Hasbro)

Yegdrion can be put to use in Stamina Customization Yegdrion 2/4/7 Glaive/Cross Orbit/Atomic.The high Stamina of 2/4/7 Glaive/Cross synergizes with Yegdrion's own and Orbit/Atomic further bolster stamina due to their low friction. This combination is capable of out spinning most of the popular Stamina/Defense Customizations but is highly vulnerable against Attack combinations.
