12 (トウェルブ, Touerubu) is a Forge Disc released as part of the Burst System as well as the Cho-Z Layer System. It debuted with the release of the B-104 Starter Winning Valkyrie 12 Volcanic on March 17th, 2018. It later debuted in western countries with the release of the Rail Rush Battle Set.
12, like other even numbered Core Discs, is symmetrical and elliptical in shape in order to facilitate a Frame. Each side features three protrusions with the center protrusion in each set featuring molding in the shape of a "12" and four holes in the center, akin to 6. While the aggressive design of the Disc may imply high Burst potential from Disc-to-Layer contact, due to the fact that most Burst Performance Tips are of the same height, such contact is rare. Furthermore, 12's design is so aggressive that there have been numerous cases of the Disc severely damaging Layers that collide with it. Finally, 12 is the lightest Disc at the time of writing, lighter than even Armed which severely hinders Attack, Defense and Stamina potential. While the light weight would create high Burst resistance, the heavy weight of the SwitchStrike/God Layer System and the Cho-Z Layer System makes the use of lightweight Discs for Burst resistance obsolete.
Due to its extremely light weight compared to many other Discs, 12 is outclassed for competitive use by all other Core Discs in all areas.
As such, 12 is recommended for collection purposes only.
