Regulus R3, known as Shelter Regulus (シェルターレグルス, Sherutā Regurusu) in Japan, is an Energy Layer released as part of the Burst System as well as the God Layer System. It debuted with the release of the B-95 Random Booster Vol. 8 Shelter Regulus.5S.Tw on October 21st, 2017. It later debuted in western countries with the release of the SwitchStrike Starter Pack Regulus R3 5Star Tower.


Regulus R3 is a Balance Type Energy Layer that features two lion heads and two lion claws on each side meant to represent this Layer’s namesake, the brightest star in the Leo Constellation, Regulus. As part of the SwitchStrike/God Layer System, Regulus R3 features a gimmick; the lion heads and claws can extend and retract in battle to create an Attack Mode and Defense Mode, akin to the Variares Metal Wheel from Metal Fight Beyblade.

Due to centrifugal force, the lion heads and claws will extend outward to increase the gaps in the Layer and when spin speed drops later in battle, the heads and claws will retract. In theory this is meant to increase Burst Attack potential early in battle and reduce Stamina draining recoil to win by Out Spin if a Burst is not achieved. However in practice, the change in recoil is minuscule at best with no observable change in performance, furthermore, Regulus R3's perimeter is square, even in "Defense Mode" which creates the recoil the gimmick was trying to avoid. Shelter Regulus' performance is further hampered by the weak teeth of the Japanese release which, when combined with the recoil inducing square shape, cause Shelter Regulus Combinations to Burst easily.


Due to Shelter Regulus' weak teeth and recoil inducing square shape, the Layer incurs Self-Bursts far to easily too be competitive.

As such, Shelter Regulus is recommended for collection purposes only.

  • Regulus R3’ gimmick is identical to Variares, only reversed.
  • Since both Regulus R3 and the Roktavor Line both use the letter "R" for identification, Regulus R3 uses a reversed "R" for differentiation
