The Fusion 4D Metal Wheel is a three component design with a Metal Frame, Rubber Frame, and Core. The Rubber Frame is made of rubber, which is intended to Spin Steal and absorb impacts from other Beyblades. As with other 4D Metal Wheels, Fusion features a mode change gimmick. Its Metal Frame and its Rubber Frame lock in with a simple square teeth system, and the same mechanism is used for the Core. By switching the position of the two frames, Fusion can switch between "Balance Mode" and "Defense Mode". In Defense Mode, the Rubber Frame is positioned on top, allowing more rubber contact and shock absorption. In Balance Mode, the Metal Frame is on top, with the round shape helping Fusion keep balanced.

The Metal Frame is shaped like a circle with bumps on the circumference. In its center ridge, there are four rectangles cut into it, which allows the Metal Frame to slide into the Core and lock in. There are also two angled parts on each side of the Metal Frame which complete the shape of the shields on the Hades Energy Ring.

Fusion's Rubber Frame has essentially the same shape as its Metal Frame. Its bumps slightly protrude from in between the Metal Frame's.
- Weight: 12.2 grams
The Core is a standard shape which has rectangular protrusions to help lock the Metal Frame and Rubber Frame onto it. This part is the only one from the Fusion 4D Metal Wheel that remains in the same position in both modes.
