Metal Weight Flat Core is a Running Core released as part of the Hard Metal System. It debuted with the releases of Thunder Serpent


  • Weight: 3 grams

Metal Weight Flat Core can be considered an upgrade to Gaia Dragoon MS's Flat Core. The added weight on the interior of the RC makes it slightly heavier, and moderately increases its survival and controllability compared to Flat Core. However, this is where the differences end; Metal Weight Flat Core has the exact same design as Flat Core in all other respects.

Mold Variations[]

The Takara Metal Weight Flat Core has a wider tip than the one that Hasbro produced. This results in a higher movement speed in the Takara version.

Use in Upper Attack Customization[]

Metal Weight Flat Core is not the most desirable choice out there for Attack types, but it can be used.

  • AR: Slash Upper (Slash Riger MS)
  • WD: Circle Wide
  • RC: Metal Weight Flat Core (Thunder Dragon)
