Stallord

"But this is truly a bittersweet reunion... Truly! For I fear this is the last time I will see you alive!"

- Zant, before plunging the sword into Stallord's skull

Twilit Fossil: Stallord is the boss of Arbiter's Grounds, Twilight Princess's fourth dungeon. Originally, Stallord is a lifeless skeleton of an ancient beast. Zant however, reanimates Stallord's fossils by plunging a twilight made sword into the skull, thereafter disappearing.

Strategy
Stallord awakens and a large sand pit forms all around him. His skeleton half protrudes from this pit sand. Link is forced to attach himself to the edge of the pit with the Spinner and ride around it. At the right time, he detaches from the wall and immediately directs himself towards the spine, attempting to dodge the non-aggressive, yet armored zombies, called Staltroops, that attempt to block his attacks. By either dodging or killing them, Link is eventually able to attack the spine three times, cracking it and bringing the Stallord down. After this the head falls to the ground, and the sand drained out of the room. By spinning the Spinner into the spinner lock in the center of the room, Link activates the gears, which caused a central pillar to rise in the middle of the room, leading to the second part of the battle.

Stallord, now just a skull, is still as alive as an undead monster can be, and as much trouble as ever. Stallord's head flies around the raised pillar, attempting to bombard Link with fireballs. Only by riding along the wall with the Spinner is Link able to catch up with Stallord's incredible speed. Stallord attacks whenever Link gets close enough, and forces him to jump from wall to wall to evade. By striking him with the Spinner, Stallord is knocked out of the air, giving Link the chance he needs to attack the sword Zant placed in Stallord's skull, during this narrow space in time called his Critical Point. However, each time Stallord rises again, more Blade Traps fill the walls, making it harder and harder to ride the wall, and forcing Link to stay on either side of the wall for a fair time, allowing the Blade Trap to pull away far enough to be harmless. Apart from this, the strategy changes little, and eventually Stallord is defeated, leaving behind only a Heart Container.

Link's Crossbow Training
In the Wii spin-off title, Link's Crossbow Training, Stallord appears as the final boss.

He is identical to his Twilight Princess appearance, but no longer has Zant's sword embedded in his skull and has 6 horns instead of just 4. He also appears to be a little darker in color, but this may be due to the different battlefield. He attacks by showering Link with meteor-like projectiles and striking him with his hands. He is vulnerable in his palms and his head. When he has taken significant damage, Stallord shoots out Bubbles to attack Link while he moves forward. Once he reaches Link, he will attack, causing him to lose points. The battle is timed, meaning that Link has only 120 seconds to defeat Stallord or he may not receive any bonus points for the stage.

Trivia

 * Stallord is currently the largest known member of the "Stal" family. Given its name, it may likely stay this way.
 * Both Stallord and the stalhounds resemble from, especially when Stallord's head is severed.
 * The phase two battle music is a remix of the King Dodongo/Volvagia music from Ocarina of Time.
 * Stallord is the first boss in Twilight Princess not to have an eye as its weak point.
 * Stallord is possibly the largest boss Link has ever fought, along with Molgera, Dark Dragon, Bongo Bongo, Twinmold, Morpheel, Cragma, and Eox.
 * Stallord is the only boss prior to Zant that was not created by coming into contact with a Fused Shadow or a piece of the Mirror of Twilight. Because of this, it is also the only boss that does not guard either of those, although a piece of the Mirror of Twilight is already left in its pedestal, which can be considered to be the piece that Link obtains for defeating Stallord.
