Energy Layer - Roktavor
Main article: Energy Layer - Roktavor
Roktavor is a rugged looking Energy Layer that bears a striking resemblance to Seaborg's Whale Attacker, featuring two flat, blunt protrusions with smaller, pointier trailing edges. Unlike most other Energy Layers that incorporate some sort of slope or relief, Roktavor has a nearly-uniform thickness throughout the Layer. The majority of Roktavor's weight is packed behind its two primary contact points, which, coupled with the shape of these protrusions, provide the Layer with a considerable amount of Burst Attack. However, these same features also subject Roktavor to large amounts of rotational recoil during a collision as well. As Ragnaruk has only three average sized teeth and one small tooth, is is unable to handle its own recoil and tends to Burst quite often, making it practically nonviable in competitive play.
Forge Disc - Heavy
Main article: Forge Disc - Heavy
Heavy is a primarily circular Forge Disc, sporting a ring-like shape with numerous ridges on its interior that is interrupted by four rectangular protrusions designed to look like armored plates. As its name suggests, Heavy was the heaviest Forge Disc in the Burst System for a considerable period of time, until Gravity, which also weighs 21.6 grams, and Quarter, which weighs 21.8 grams were released. Despite this, Heavy is still one of the heaviest Forge Discs in the game, making it a popular choice for many Bladers. As its weight is a welcome asset to nearly any Beyblade, it enjoys a wide variety of uses on Combinations of all types. Heavy's high weight and compact shape gives it a Centralized Weight Distribution, making it particularly useful for Burst Attack as it will maximize the RPM of the Beyblade. This same weight distribution also makes it considerably more difficult to Burst than Gravity, the other disc in its weight class, at the cost of a significant amount of Stamina. Because of this, it is a better option for a KO Defense Combination than Gravity as KO Defense Combinations rely on high friction and weight to remain in the stadium, at the same time increasing their vulnerability to Bursting. However, due to its weight, Heavy is still more prone to Bursting than most lighter competitive Forge Discs such as Spread, Knuckle, and Armed.
Performance Tip - Survive
Main article: Performance Tip - Survive
Survive is extremely similar to the Metal Fight Beyblade Performance Tip Defense (D), with a low-angled cone shape protruding from a cylinder. As a result, while it is overpowered by some Heavy Defense Combinations, it has still shown to be useful in Stamina-based Burst Combinations like Defense does for Metal Fight Beyblade Combinations.
However, it can also be used as a Defense Performance Tip in absence of better ones, and while it is outclassed, its shape helps it rebound from attacks to avoid being KO'd. While good ball-shaped or rubber sharp Performance Tips lack in Beyblade Burst, Survive has enough stability to take hits without losing all balance and precessing too early like sharper tips.
