Black coat

The Black Coat (sometimes called an Organization coat, or incorrectly as a black cloak) is a common form of attire for many characters in Kingdom Hearts. It protects the wearer from the darkness in various ways, and in some cases, from detection methods available to those who wield darkness.

It is assumed that this coat is worn by those who regularly travel through the Corridors of Darkness. It appears that the black coat is granted to those who travel through the Corridors of Darkness as a symbol of their ability to resist the potential corruption in doing so.

Somehow, when Riku and King Mickey cast their cloaks off, the black gloves, pants, and boots worn under the cloak disappear. Furthermore, any trace of the wearer's clothing under the coat disappears, such as Riku's collar, jeans, and sneakers in his second attire, or Mickey's trademark white gloves. All these hint that donning the coat transforms whatever clothing the coat's bearer is wearing under it into the black gloves, pants, and boots seen on all the coat's wearers.

The Black Coat seems to adapt to the form of its user, as shown when Xion's form changes to resemble Roxas and Sora.

Kingdom Hearts Birth by Sleep
In Kingdom Hearts Birth by Sleep, Master Xehanort is seen wearing a black coat near Ventus (who is wrapped in a white cloth) on Destiny Islands. In Birth by Sleep's True Ending, taking place after Kingdom Hearts II, Ansem the Wise is also seen wearing the black coat at the Dark Meridian.

Kingdom Hearts Final Mix
In Kingdom Hearts Final Mix, Xemnas is seen wearing the black coat when fighting Sora in Hollow Bastion.

Kingdom Hearts 358/2 Days
In Kingdom Hearts 358/2 Days, Moogles also wear the black coat, as a sign of their services for Organization XIII.

Kingdom Hearts: Chain of Memories
Later, in Kingdom Hearts: Chain of Memories, Riku and King Mickey are given Black Coats by DiZ, so that they would not be tracked down by Organization XIII. Riku continues to wear the coat throughout Kingdom Hearts 358/2 Days and Kingdom Hearts II, until the explosion of the Kingdom Hearts Encoder returns him to his original form. What's interesting about Mickey's coat is that it is much smaller since it's catered to his body. Even the hood is sewn just for Mickey, with places for his ears. When Goofy is injured after the fight with Demyx, Mickey removes and discards his coat and charges into the Great Maw.

Kingdom Hearts II
In Kingdom Hearts II, all the members of Organization XIII wear the black coat. King Mickey also dons the black coat until taking it off later in the game, and Riku is seen wearing it while being possessed by Xehanort's Heartless. He takes it off after reverting back to his original form.



Kingdom Hearts coded
In Kingdom Hearts coded, a mysterious figure is seen in the black coat. In the fourth episode, it is revealed that the man is actually Jiminy's Journal taking on the form of Riku in his coat while helping Sora. The Journal mentions having met the Data Sora in Traverse Town first, leading to speculation that another as-of-yet unknown person in the coat has appeared.

Organization XIII
Among the most notable characters that sport the black coat are the members of Organization XIII. The Organization's coats are not uniform in appearance. For instance, Axel's coat has tight sleeves, while Xigbar and Demyx both wear coats with pointed shoulders. Additionally, Vexen's coat is longer than most other members, to the point that it covers his feet and its sleeves partially cover his hands. Roxas and Xion in Sora form wear what appear to be black sneakers, while Larxene and Xion in her normal form wear heeled boots.

Trivia

 * The black coats were originally designed for Roxas and Riku in the secret video Another Side, Another Story... simply as a way to disguise them while they were still being designed for Kingdom Hearts II. It was then given to Xemnas in his optional boss battle in Kingdom Hearts Final Mix and in Deep Dive, starting the trend of all Organization members wearing it. It was again used simply to hide his face here.
