Striker II or Unicorno II (ユニコルノII, Yunikoruno II) is an Energy Ring released by Takara Tomy. It debuted in Japan with the release of the BB-117 Strongest Blader Set on August 6, 2011. It debuted in western countries with the release of the BB-117-FX Spark FX Starter Pack Blitz Striker 100RSF.
Striker II resembles its predecessor Striker I, with a new purple horn design. The three horns are more elevated than those of Striker I, and heavier. The horns of Striker II are intended to align with three-wing Fusion Wheels such as the Blitz Fusion Wheel. Like other 4D Clear Wheels, Takara Tomy's release of Striker II contained trace amounts of iron powder, which was advertised to increase its weight.
