G:D is a stamina bottom that can be related to a counter B:D. the tip on G:D is not free spinning, and its inner disk spins independently, so it has "double rotation", thus have the ability to slow down and increase speed, only until the inner disk stops spinning.
In the middle of the wd shaped tip is a button, used to activate the G:D. simply, just rotate the center of the tip and it will lock when fully winded. then, once you launch the bey, the tip will push down, thus activating the inner disk gimmick. after it is fully released, the center of the tip will stop spinning, however, the internal disk will continue to remain spinning.
The internal disk is heavier than the rest of the 4D bottom, as it is metal. the rest of the 4D bottom is plastic.
The shell is plastic, and mainly looks like a gyroscope. However, near the bottom of the internal disk is cased, as the mechanics are located there.
G:D would be the tip of the possible Zero-G bey Gladiator Hydra G:D.
