Bunshin Core is a Running Core released as part of the Hard Metal System It debuted with the release of Phantom Fox MS.


  • Weight: 8 grams

The RC of Phantom Fox MS, the Bunshin Core, is divided into two separate parts. The upper part and the lower part, both of which spin independently of each other when their separation is triggered by a hit. In this article, they will be referred to as “Bunshin Core (Upper Part)” and “Bunshin Core (Lower Part)”.

Bunshin Core (Upper Part)

This is the part which the AR is attached to. It is made of plastic and has a spring-loaded semi-flat tip that is shot at just a high enough distance for it to separate itself from Bunshin Core (Lower Part). No WD can be attached to this part.

Bunshin Core (Lower Part)

At the beginning of a battle, this is the part that first acts as Phantom Fox's RC. It holds a WD within it, and has interchangeable tips. These tips are attached in a similar fashion to how Bit Protectors are attached. By default it comes packages with a semi-flat tip, but a flat and sharp tip are available through Fukobako 2005.

In an attempt to give some type of weight to each part, they separated the AR and WD. This however effectively halves the overall weight, making each part easily knocked out. Next to being a fun part to watch, Bunshin Core as a whole has no real practical applications in competitive battling.

Ruling Clarification

When the Bunshin Core is separated and one part ceases to spin in the Beystadium, you must leave the part where it is until the battle is completed.
