The Guard Armor is an Emblem Heartless that is found in Kingdom Hearts, Kingdom Hearts: Chain of Memories, Kingdom Hearts 358/2 Days, Kingdom Hearts coded, and all of their remakes. It is one of the bosses at Traverse Town and Olympus Coliseum.
The various pieces of the Guard Armor, known as "Armored Torso", "Gauntlets", and "Hammerlegs", are able to move independently, and by rearranging its pieces, the Guard Armor can transform into the more powerful Opposite Armor.
The first Guard Armor attacks Sora right after he meets Donald and Goofy and they slay a gang of Soldier Heartless. It is the leader of the Traverse Town Heartless, and after it is defeated, the local Heartless temporarily calm down.
Later, Sora tests the legend about the Second District bell by ringing it three times, and the world's Keyhole is revealed within the district's fountain. However, as the group goes to seal it they are attacked by a second Guard Armor, and though they defeat it, it transforms itself into the stronger Opposite Armor and attacks again. After it is destroyed, they are able to seal Traverse Town's Keyhole.
Kingdom Hearts: Chain of Memories
Sora explores the memory version of Traverse Town within Castle Oblivion and meets Cid, who warns him that a giant Heartless is said to appear when the Second District bell rings. Just as it did before, the bell rings, and the Guard Armor suddenly appears. Sora defeats it, and Leon, Cid, Yuffie, and Aerith see him off to the exit.
Another Guard Armor appears in Riku's version of Traverse Town, but this one is simply a manifestation of the darkness in his heart, and is quickly defeated.
Kingdom Hearts 358/2 Days
Roxas is dueling Xigbar in the Olympus Coliseum Games when a Guard Armor interrupts. Xigbar steps out to let Roxas defeat the Guard Armor on his own, and while fighting it Roxas has flashbacks to when Sora fought the Guard Armor in exactly the same manner, mirroring Roxas's combat patterns and abilities. However, the Guard Armor is soon defeated, and Roxas "wins" the Games.
Kingdom Hearts coded
After Data-Sora unlocks the Keyhole of Data Traverse Town, he encounters data-Guard Armor, which happens to be the source of Bug Blox corruption in data-Traverse Town. Data-Sora defeats it afterwards and restores the data-Traverse Town.
The Guard Armor's body is divided into several pieces—a body, a head, two arms, and two legs—none of which are directly connected to each other and all of which can act independently of the other. The Armored Torso is vaguely hour glass-shaped, violet with a lilac, diamond pattern around its waist, and has light black additives on it. The Heartless emblem is emblazoned on the center of the armor. Its head is violet, spherical, and sports three silver spikes and a silver faceplate with several holes in it. Both of the Gauntlets are violet with wide wrists and three lilac, segmented fingers. The Hammerlegs are short, violet, and ends in large, hammer-like, black feet. All of the pieces of the Guard Armor seem to be hollow.
In Kingdom Hearts Final Mix, the violet sections of the Guard Armor are silver, its torso gains red, yellow, and blue stripes on its upper half, its head becomes red with yellow spikes, and the additives on its top and upper rims become blue and yellow, respectively. Its fingers become grey, while its feet become red.
The Guard Armor's name references its armored body and the fact that it first protects the Heartless in Traverse Town, and later guards the Traverse Town Keyhole.
The Guard Armor utilizes its size and strength in battle. Each part attacks individually; the Torso and Gauntlets attack by spinning, while the Hammerlegs attack by stomping. It may also jump in the air and crash down, creating a shockwave.
Lock onto its torso and attack with combos, since Sora's attacks will most likely strike the limbs as he go past them.
Hitting the torso also keeps it from launching its main attack. Just remember to destroy the limbs before destroying the torso. Doing so will make the limbs drop needed HP balls. The Guard Armor will also throw itself up in the air and come crashing down near Sora's position. Try to dodge this by jumping out of the way, as it will take away half of Sora's HP if hit. Its attacks are deflectable.
Kingdom Hearts: Chain of Memories
The strategy for the Guard Armor is slightly different in Kingdom Hearts: Chain of Memories due to not having unlimited attacks. Using the Gimmick card will make the Guard Armor collapse and this allows Sora to attack the limbs. When the Guard Armor is only the torso and head, attacking the head is simple, but be sure to dodge the attacks quickly as Sora does not have that much HP.
Kingdom Hearts 358/2 Days
The Guard Armor is extremely resilient against all forms of magic, so use melee attacks to overcome it. Jump and attack its head, then move away when it begins to march and swat at the ground, then circle it to continue attacking its head.
Sometimes the Guard Armor leaps into the air and crashes to the ground, releasing a mild shockwave that causes minor damage. When this happens, its head falls off. While it scrambles to recover its head, run up and attack the helmet on the ground.
Afterwards, the Guard Armor reattaches its head, but the damage inflicted causes its arms and legs to separate from the torso and act independently. Lock on to the arms and attack them, using Limit Breaks if possible. Destroy both limbs before the Guard Armor reassembles itself. Otherwise, if one limb is destroyed and not the other, the missing limb regenerates after the boss reassembles. The Guard Armor also regains some HP during this regeneration process.
Eliminate both arms, then do the same with the legs. When the legs and arms are gone, the floating torso becomes helpless and just spins to defend itself. Continue attacking the helmet until the Guard Armor collapses.
Kingdom Hearts Re:coded
The Guard Armor in Kingdom Hearts Re:coded is fairly easy to beat. At the start of the battle it will jump and stomp the ground, this can be easily avoided with a well-timed Dodge Roll. If the Guard Armor jumps and disappears on top of the screen, be ready to dodge as a few columns of blox will fall along with it. If it raises both its hands, it will shoot both of them towards Data-Sora, either dodge by using Dodge Roll or just jump out of the way. It can also summon a Soldier or Shadow, but be careful when it does, as this is usually a sign that it is about to ready its cannon. Although the cannon seems threatening, it's actually very easy to dodge, just run to the opposite direction of the Guard Armor, or right under it, and stay there. The cannon's charging time is pretty long, so Sora should have plenty of time to get out of the way. It will be open to triple damage while charging its cannon, so attack it or use Overlay commands like Thunder Rain or Blizzard Dart. It is recommended to be under the Guard Armor while doing this to avoid taking immense damage.
Overlay commands can really help in this fight, especially Blizzard Dart since it's ranged. Otherwise, look for openings, attack and the Guard Armor should fall with ease.
