Upper (アッパー, Appā) is a Forge Disc released as part of the Burst System. It debuted with the release of the B-44 Booster Holy Horusood Upper Claw on May 28th, 2016. It later debuted in western countries with the release of the Starter Pack Horusood H2 Upper Claw.
Upper features two sloped metal wings that, in theory, provide Upper Force in Right-Spin and Down Force in Left-Spin. However, in practice, the low angle and short width of the wings makes any Upper or Down Force effect negligible. Furthermore, Upper is light in weight, lower than the more popular choices for Stamina; 4 and 7, making its KO resistance sub-par compared to the aforementioned Discs.
As such, Upper is recommended for collection purposes only.
