When Gear 4 Appear ^new^ -

Gear Fourth is fundamentally different from previous Gears. Instead of just pumping blood (Gear Second) or inflating his bones (Gear Third), Luffy blows air into his and then coats his entire body with Busoshoku Haki (Armament Haki).

To understand the gravity of Gear Four’s appearance, one must first examine the context of its debut. The Dressrosa Arc was defined by the tyranny of Donquixote Doflamingo, a Shichibukai (Warlord of the Sea) whose physical strength and influence were second only to the Yonko (Emperors). Leading up to the confrontation, Luffy had faced Warlords before, but Doflamingo represented a different echelon of threat. He was a man who held an entire kingdom in a literal and figurative grip of strings. When Luffy’s standard Gear Second and Third techniques failed to pierce Doflamingo’s formidable defenses, the narrative tension reached a breaking point. The audience realized, along with Luffy, that the brute force of the past was no longer sufficient. The appearance of Gear Four was the solution to a problem that threatened to end Luffy's journey permanently. when gear 4 appear
