Guard Armor

The Guard Armor (ガードアーマー) is an Emblem Heartless that is found in Kingdom Hearts, Kingdom Hearts: Chain of Memories, and Kingdom Hearts 358/2 Days. It is one of the bosses at Traverse Town. 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.

Kingdom Hearts
''Leader of the Heartless in Traverse Town. It falls apart when it receives damage, but each part attacks individually. Sora meets Donald and Goofy for the first time just before fighting this Heartless.''

Kingdom Hearts: Chain of Memories
A Heartless that haunts Traverse Town. It appeared when the bells rang to wreak havoc on the town.
 * Sora's Story

''A Heartless that haunts Traverse Town. It appeared before Riku as a token of the indelible darkness in his heart.''
 * Reverse/Rebirth

Kingdom Hearts 358/2 Days
Large and heavily armored, these Heartless will jump and then crash into the ground, creating a powerful shockwave. ''They drop their heads after landing, however; strike then and the body will eventually fall to pieces, with each piece acting autonomously. Start with the limbs and take them all out.''

Kingdom Hearts
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 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. However, the Guard Armor is soon defeated, and Roxas "wins" the Games.

Kingdom Hearts coded
When Data Sora opened the Data Keyhole of Data Traverse Town, he fought Data Guard Armor, which happened to be the source of Block corruption in Data Traverse Town.

Kingdom Hearts
This Boss has a torso and four limbs, all of which act as targets. Remember to watch over your new teammates, since this is your first time controlling a party. Lock onto its torso and attack with combos, since your attacks will most likely strike the limbs as you go past them. Hitting the torso also keeps it from launching its main attack. Just remember to destroy the limbs before you actually finish off the torso.

Kingdom Hearts: Chain of Memories
The strategy for the Guard Armor is slightly different in Kingdom Hearts: Chain of Memories due to the fact of not having unlimited attacks. Using the Green Mickey card will make the Guard Armor collapse and this allows you to attack the limbs respectively. Then when the Guard Armor is only the torso and head, attacking the head is simple but one must dodge the attacks quickly as Sora does not have that much HP.

In Re: Chain of Memories using a Goofy Friend Card and two keyblade cards to use Goofy's strike limit attack works wonders in this battle.

Trivia

 * In the original version of Chain of Memories, the Guard Armor was incorrectly fought in the Third District, where the first Guard Armor appeared in Kingdom Hearts, even though the previous scene was set in the Second District, where the ringing bell summoned the second Guard Armor. This was corrected in Re:Chain of Memories.
