Unlike its normal self, a Furious Rajang is not a Subspecies but rather a revamp Variant of an Rajang, which in its dormant state appears to be "almost golden as if it were to be locked in its rage mode". Its Rage mode shows that its fur stands up and it is visibly electrified by an electric aura.
This variant of Rajang also appears in Monster Hunter 4 with separate Icon, yet it does not have a separate name from an ordinary Rajang.
Ultra-aggressive creature that is rarely sighted and seldom survived. Survivors report it exhibits a strange attack. The Rajang is said to be a loner, and this isolated life has made it difficult to pin down its territorial leanings.
