Body Set: Bison
Head Part: Bison Head
This Head Part is based on a bull's face as evident through its design. It is a bright red, using a red and black decal on its forehead with a red, golden-edged hexagon depicting a black bull's head with red eyes. It features two long, curved horns known as the "Bison Horns". Due to their design (with its multitude of indents), it serves as a Grip for the B-Daman. Additionally, they attach at the head's sides and are detachable to be placed onto the Bison Arms, acting as Stabilizers for "Stabilizer Mode/Full Horn Mode".
Arm Parts: Bison Arms
The Arm Parts have big cylinder-like armor plates using black, gray and red stickers resembling waves. The rest of these bright red arms are longer and thinner, also using yellow and blue stickers at the hands. It also features holes for the Bison Horns to attach, converting the B-Daman into Stabilizer/Full Horn Mode.
These Stud Parts are a copper-brown in color.
Leg Part: Bison Leg
The Leg Part is rather large in surface area, thanks to how long and thick the feet area is with circular impressions. They are bright red and use red, black, gray, yellow and blue stickers.
Core Part: Burst
The Burst Core, unlike with most other Core Parts, has no spring in its Trigger, which is where its gimmick comes in; a special extension, the Bison Grip, allows the user to pull and push the Trigger to fire B-Dama with the strength in his arm. It uses the same type of body shell as Spin.
