Phantom Ganon (Ocarina of Time)

The Evil Spirit from Beyond: Phantom Ganon is the boss of the Forest Temple, the first dungeon in the adult portion of The Legend of Zelda: Ocarina of Time. Created by Ganondorf to hold Saria captive, he is depicted as being near identical to Ganondorf, with the only exception being his skull-like face.

Story
When Link enters the boss chamber in the Forest Temple, he must climb a set of stairs. When he reaches the top, he finds himself in a circular room. Identical paintings of a dirt trail leading through a dark forest, with a castle in the background adorn the walls of the chamber, and all is quiet. It is not until Link attempts to walk back down the stairs that Phantom Ganon appears. Once the stairs are approached, a metal fense jolts out of the ground, impeding Link's path.

All of a sudden Phantom Ganon, atop his horse appears in the center of the room. He gallops into one of the paintings, and the battle begins.

Battle
Phantom Ganon's fighting style consists of the use of a lance, in conjunction with magic attacks and a replica of his master's steed. He starts off by riding from within a painting towards Link, confusing him by appearing in two paintings at once. However, the darker image will turn back from the surface of the painting at the last moment, indicating that the other is the true Phantom, and Link must shoot him with his bow as he rides out. If he is not hit, he will fire an energy blast at Link, depleting two of his hearts.

Eventually the horse will be destroyed, and Phantom Ganon will resort to hovering over the field of battle, using his staff to fire energy balls at Link, which Link must deflect without being hit himself in a game of Dead Man's Volley. If he is hit, he loses one heart container. Once he successfully deflects the energy ball, Link can then move in and engage the Phantom in close quarters until the Phantom rises. Nearing the end, Phantom Ganon will also mount his staff and charge at Link, hoping to impale him. This particular attack is the most powerful attack that appears in the game (until the player faces Bongo Bongo) and will instantly defeat anyone attempting to complete the game without obtaining any extra Heart Containers. All Link has to do is dodge this attack, wait for the Phantom to fire another energy ball, then revive his strategy.

After Link slashes him roughly a dozen times, the Phantom falls defeated; and the real Ganondorf's voice is heard in the hall, possibly through the phantom itself, or the case may be that he speaks directly into Link's mind, taunting him that the real King of Evil will not be as easily vanquished; he then banishes the writhing Phantom to the "gap between dimensions".
