Flame-X Diomedes D4, despite the added prefix and "D4" suffix, is simply a recolored Hasbro Diomedes D2. As such, one should refer to the Diomedes D2 page for information on performance.

Forge Disc - 8

Main article: Forge Disc - 8
8, like other even numbered Core Discs, is symmetrical and elliptical in shape in order to facilitate a Disc Frame. Each side features four protrusions, each molded into the shape of an "8". Each of the lower loops of the "8"s features gaps, akin to Knuckle, which takes weight away from the center and creates high Outward Weight Distribution and subsequent Flywheel Effect, features theoretically perfect for Stamina. Furthermore, 8 is one of the heaviest Discs in the game, heavier than Heavy, Gravity, 2, 4, and 6 and its use can bolster a Beyblade's KO resistance and Attack potential. However, like other heavy discs with high Outward Weight Distribution such as Gravity and Ring, the use of 8 severely decreases a Beyblade's Burst resistance as a trade off.

Performance Tip - Defense-S

Main article: Performance Tip - Defense-S
Defense-S is a Performance Tip that features a ball tip with four tabs, and a protective disk that sits halfway down the Performance Tip. Its height is significantly increased in order to facilitate its SlingShock gimmick. Defense-S features a mode-change gimmick, able to switch from "Battle Ring Mode" to "SlingShock Mode".

In "Battle Ring Mode", Defense-S performs as a standard ball tip. Due to the small size of the ball tip, Defense-S has a small surface area, though not to the degree of Performance Tips such as Orbit, Yard-S, and Atomic. The four tabs surrounding the ball tip act as brakes against KOs by striking against the stadium floor when the Defense-S Combination is struck, at the cost of Stamina. While the increase in height may imply that the ring of Defense-S has a better chance of making contact with the opponent's Layer, it is positioned too low for any opposing Layer to make contact with. Furthermore, the ring of Defense-S has four protrusions, which nullifies its Life After Death potential.

In "SlingShock Mode", the ball tip is hidden, revealing a small hole-flat tip that's more akin to Zephyr. This mode gives the Defense-S Combination a huge boost of speed as well as an increase in Stamina thanks to the hole-flat tip. Since the height of both Battle Ring Mode and SlingShock Mode are similar, the Defense-S Combination isn't as prone to being destabilized as other SlingShock Performance Tips like Jolt-S and Xtend-S. While SlingShock Mode may imply that a Defense-S Combination in this mode is capable of maintaining a Banking Pattern, the four tabs of the tip makes maintaining a Banking Pattern impossible. Of the two modes, Battle Ring Mode has the greater success.
