Phantom Ganon

Phantom Ganon (ファントムガノン, Fantomu Ganon) is a recurring boss in Hyrule Warriors Legends. He is an enemy that made his first appearance in Ocarina of Time, and has played a major role in nearly every Zelda game in which Ganondorf makes an appearance. The Hyrule Warriors incarnation is taken from The Wind Waker.

Role in Game
Phantom Ganon appears as the main villain of the Wind Waker segment of Legend Mode. It's revealed that, in attempt to increase his power, Phantom Ganon stole the Triforce of Power from Lana and sealed Cia's spirit within the Temple of Souls, then created a shadowy clone of her named Dark Cia to steal her magic. Using the Triforce of Power he tore open another rift in time and space, this time to the Great Sea, and Link was sent to investigate. He was soon joined by Tetra, Lana, King Daphnes Nohansen Hyrule, and even a revived and redeemed Cia. Together this group destroyed Dark Cia, then traveled to Phantom Ganon's lair in a merged version of the Wind and Earth Temples to confront him.

In the ensuing battle, the group combined their strengths to weaken the Evil Spirit from Beyond, and destroyed him. With his destruction, the rift closed, Cia regained her magic, and both her and Lana regained the Triforce of Power, now shared between them. Notably, it's never clear what exactly Phantom Ganon intended to do with his stolen resources, if anything.

Counter Strategies
Like The Imprisoned and the Great Fairy, Phantom Ganon has no Item based weakness. For the first phase of his fight, one must bounce back his projectiles to reveal his weak point gauge. Due to the randomness of his attack patterns, fighting Phantom Ganon can some times drag on longer than players would like, especially when fighting him in Adventure Mode. One alternate way to get him into his Weal Point stance is to attack him directly in the back, have him target your allies instead of you and attacking him in the back enough times will make his Weak Point Gauge appear.
