Big Bang is the first 4D fusion wheel to be introduced in the Metal Saga. Big Bang is 50 mm wide, making it the widest fusion wheel upon its arrival. It was a much anticipated part of the newly-arrived 4D System, but performance-wise, Big Bang didn't feature great use in Attack. It is best used with tall Spin Tracks, which not only increases its attack power but it's defense as well. There have also been prominent signs of "Force Smash" from Big Bang, a form of attack in which a downward impact is exerted on an opposing bey.
So despite this, Big Bang may be flawed, but is a decent Attack-Type Wheel to say the least. Fusion Wheels like Blitz, Variares, and Beat are much better than Big Bang but in all in all, Big Bang is a decent 4D Fusion Wheel at best.
By rotating the PC Frame and the Core, Big Bang can change between a total of four different Modes, "Directional Attack Mode", "Attack Mode", "Multi-Attack Mode", and "Upper Attack Mode". Its Upper Attack Mode is useful for getting other beys into traps and stadium outs. Due to this, Gingka uses Upper Attack Mode more often rather than the other modes, along with Directional Attack Mode. Its Attack Mode is a superior to the three modes, due to its prominent Attack power. In Multi-Attack Mode however, it suffers from recoil, but still remain as a decent mode.

Big Bang features a PC Frame, with PC being an abbreviation of polycarbonate of which, it is constructed of. Big Bang's Plastic Wheel is a translucent red that bears a three-winged design similar to Storm. As always, these three wings are meant to represent Pegasus' wings and feature a slanted gap between each wing. Big Bang's Plastic Wheel also features two square-like holes on each wing in order to help change it's Mode with Big Bang's Attack Wheel.

Big Bang features a Attack Wheel, in which, along with the Metal Wheel, make contact with the opposing Bey. Big Bang's Attack Wheel resembles Storm, just like it's Plastic Wheel. However, it is bulkier and the wings tend to curve upwards rather than Storm's more flatter wings. It also uses three small square-like protrusions sprouting out on each wing, in order for the Plastic Wheel to fit into place and to change Modes. Big Bang's Attack Wheel is coloured metallic silver.

The last part of Big Bang is it's Metal Wheel. It is compromised of three, flat, and sharp wings going in a left-ward movement. This makes the overall contact of the Big Bang's Fusion Wheel along with the Attack Wheel. It also is designed to hold the Attack Wheel into place. It is coloured metallic silver.
