The Imprisoned

The Imprisoned (封印されしもの) is a character from The Legend of Zelda: Skyward Sword. It is a giant, mysterious beast who haunts Link's dreams. The Imprisoned dwells within the Sealed Grounds, and Link must fight it on several occasions throughout his quest, with the monster gaining a new attribute or ability each time.

Biography
After his failed attempt to obtain the Triforce, Demise was transformed into the Imprisoned by the goddess Hylia and trapped within the Sealed Grounds. In the present day, Demise's servant, Ghirahim, seeks to break the seal on his master and return him to his original form by using the soul of Zelda, the human reincarnation of Hylia.

The Imprisoned eventually manages to break free of its seal when Link goes to the Sealed Temple with Groose, just before Link activates the Gate of Time, and when Link goes to Faron Woods to learn Faron's part to The Song of the Hero, but Link manages to defeat it and restore the seal each time. Later, when Link obtains the Triforce, he and Fi use it to wish for Demise's destruction; in accordance with this wish, the Isle of the Goddess detaches from Skyloft and plummets back to the Surface, crushing the Imprisoned beneath it just as it was breaking free of its seal for a fourth time.

Unfortunately, Ghirahim circumvents this by kidnapping Zelda and traveling back in time to resurrect Demise in the past. Despite Link's best efforts to stop him, Ghirahim successfully completes the ritual; the Imprisoned emerges from its seal and devours Zelda's soul, allowing Demise to return.

Ironically, the three boss battles with The Imprisoned that precede the ultimate face-off with Demise are a result of Demise's defeat in the past at the end of Skyward Sword. Chronologically, the events of Skyward Sword begin with Link's defeat of Demise in the past and progress to the loosening of The Imprisoned's seal in the present, then to Link's re-sealing The Imprisoned at the Sealed Grounds, and lastly to the ultimate defeat of Demise via the Triforce and the Isle of the Goddess. In this way, the battle with Demise at the end of Skyward Sword occurred before Link faces The Imprisoned for the first time.

Battle
The Imprisoned is far too powerful to outright destroy in battle; instead, Link must attack the sealing spike on the monster's head, damaging the Imprisoned when it is shoved all the way into its skull. After damaging the monster in this way three times, the Imprisoned will be forced back into the ground, allowing Link to restore the seal with a Skyward Strike.

To gain access to the sealing spike, Link must use one of two strategies. He can destroy all eight of the Imprisoned's toes to topple the monster and expose the spike, or use the updrafts around the pit to reach a position above the beast and jump onto its head where the seal is located. In either case, the Imprisoned must be defeated quickly; if it reaches the top of the pit and destroys the Sealed Temple, Link will receive an instant Game Over.

Round One
In the first battle, the Imprisoned simply lumbers around the spiral path to emerge from the pit, ignoring Link almost entirely. It can create a damaging shockwave by stomping its foot on the ground, but Link can avoid the attack by backing away when the Imprisoned's scales glow red. After taking damage from the sealing spike, it briefly becomes invincible and slithers on its belly to cover some ground, damaging Link if he is in the way. When it nears defeat, it begins creating shockwaves with every step, forcing Link to time his attacks on the feet or necessitating the use of the second method of attack.

Round Two
In the second match, the Imprisoned is faster than before, and begins generating shockwaves right from the start. Its new arms allow it to scale the side of the pit, allowing it to cover distance more effectively, and block Link's path to the sealing spike if the toes are destroyed, forcing him to use the updrafts. Additionally, it will try to shake Link off its head by flailing backwards.

Luckily, the Groosenator's bombs can stun the Imprisoned, knocking it off the wall if it is climbing and staggering it if it is walking. Either way, it is immobilized, leaving the toes and the sealing spike as easy targets.

While waiting for Groose to ready the Groosenator for the next shot, Link can circumvent the foot-based shockwaves using his Bow to hit the Imprisoned's toes.

Round Three
The Imprisoned's tail seems mostly cosmetic, although it can knock Link back when he is trying to catch up with the monster, and, if the toes are destroyed, stop Link getting to the sealing spike as quickly. The Imprisoned gains yet another speed boost for its third attack on the Sacred Temple; attacking it is nearly impossible unless it is stunned by the Groosenator first. If a bomb is missed or Link needs to speed things up or conserve health, he can again circumvent the Imprisoned and its shockwaves by using updrafts to get ahead of it, then fire his Bow at its toes. After taking a hit, it will manifest a halo-like ring on its back and begin floating out of the pit. A well-aimed bomb from the Groosenator will knock it back to the bottom, giving Link a chance to hit the sealing spike again.

Unfortunately, the Imprisoned's fall also causes a structure to collapse, blocking off Groose's supply of bombs and preventing him from repeating his strategy. As the monster begins to rise once more, Link must quickly ascend to the top of the pit using updrafts and meet up with Groose, who decides that the only way to save the temple now is to launch Link himself onto the Imprisoned's head. Groose must take careful aim with the Groosenator as the enemy rises into view and fire Link right next to the sealing spike. Alternatively, Link can wait until the last moment in the bottom of the pit. If he does, a powerful updraft will appear where the sealing spike was, which will launch him high in the air, giving a chance to land onto the monster. When Link is on the Imprisoned's head, he must attack it one last time to defeat it once again.
