Hot Topic merchandise

Beginning in the early June of 2009, the clothing store Hot Topic began to produce Kingdom Hearts-based t-shirts. The store began by selling three designs: two unisex designs and one that is female-only. All three designs contain two designs that were both Puzzles in Kingdom Hearts II Final Mix. The two unisex designs feature the Awakening and Heart puzzles, whereas the female shirt features the EDGE puzzle.

In reaction to the profiting sales of their original three designs, Hot Topic then released another unisex t-shirt. However, unlike the other shirts, this one was not based off of a Puzzle. Instead, this shirt is black, has the Kingdom Hearts II logo centered in the middle, and has silver silhouettes of every Keyblade that appears in the game.

Since then, Hot Topic has released several other pieces of clothing based on the Kingdom Hearts series. Two more unisex shirts have been created, the first of these featuring many of the main characters over a pure-black background, all facing forward. The second is Hot Topic's first (and currently only) Kingdom Hearts-based hoodie. The hoodie is black, and featured four perpendicular squares featuring a headshot of one main character each. The top left is King Mickey, the top right is Sora, the bottom left is Goofy, and the bottom right is Donald. More shirts have since been added, another female-oriented shirt was created. This black shirt contains a picture of Sora, Donald, and Goofy in battle position over a white area, with the phrase "BEWARE THE HEARTLESS" written above them and another shirt with Sora in his Vampire Form with the Way to the Dawn Keyblade in the background.

The only t-shirt based on Kingdom Hearts 358/2 Days is a shirt with the cover design of the game and it comes for both genders. The most recent additions to the T-shirt collection is one featuring Mickey in his Organization coat and another group T-shirt. The store also began to produce three different Kingdom Hearts II-based pins; they model the Kingdom Key, Heartless insignia, and logo of Kingdom Hearts II.
