The inclusion of rubber aids in this Layer's ability to equalize spin with a Right-Spin opponent.
The second is that the 'F's are made of rubber, akin to both its predecessor.
Geist Fafnir also features gimmicks: The first is that this Layer is meant to spin Left, opposite to most other Beyblades. Takara Tomy's Geist Fafnir, like its predecessor Drain Fafnir, is a Stamina Type Energy Layer that features a triangular perimeter and three side profile dragon heads with an 'F' along each, meant to represent this Layer's namesake Fafnir the Nordic Dragon of Greed. As part of the Cho-Z Layer System, Geist Fafnir features metal in its design in this case, interspersed between the dragon heads. The inclusion of metal makes this Layer heavier than most God Layers.
