11 (イレブン, Irebun) 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-105 Starter Z Achilles 11 Xtend on March 17th, 2018. It later debuted in western countries with the release of the Rail Rush Battle Set as well as the SlingShock Starter Pack Z Achilles A4 11 Xtend-S.
11, unlike most other odd numbered Core Discs, is symmetrical and elliptical in shape in order to facilitate a Frame. Each side features one large protrusion to create the visage of an "11" with one protrusion featuring a large "1" shaped indent to create an unbalanced design, however the shallow depth of the indent creates no noticeable effect. Compared to other Core Discs, 11 is one of the lightest, even lighter than most non-Core Discs. This light weight severely hinders 11's Attack, Defense and Stamina potential and 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, 11 is outclassed for competitive use by all other Core Discs in all areas.
As such, 11 is recommended for collection purposes only.
