DigiMemory (Xros Wars)

A DigiMemory (Dub: DigiCards) is an item which resembles a  that appears in Digimon Xros Wars. The data of "legendary Digimon" are stored on them and can be used with the Digimon Xros Loader to summon those Digimon. They depict an official Bandai image of a Digimon along with their name, the character for "Technique" written inside a green hexagon, and one of their Special Moves displayed at the bottom. They are the stored data of the legendary guardian knights of the Digital World who fought against Bagramon in the past with the attempt to prevent him from ruling both the Real and Digital World.

Description
The Digimon represented by the fifteen DigiMemories were once a chivalric order that protected the Digital World. When Bagramon learned of the Real World and decided to conquer it they fought against it and were able to hold it back for a time. However, the growth of digital technology in the Real World caused the two worlds to become closer and closer, eventually destabilizing the core and causing it to shatter into the one hundred and eight Code Crowns. This explosion reduced the knights to spiritual remnants which took the form of the DigiMemories. Most of the DigiMemories were scattered around the Digital World, but Examon and War Greymon's were left adrift in the Digital Space, and Omegamon's was catapulted all the way to in the Human World.

Summoning Digimon
When summoning legendary Digimon, the user inserts a DigiMemory into their Xros Loader and shouts out the name of the technique displayed on the DigiMemory followed by "Activate!" . Digital screens appear either side of the user, containing information such as Special Move descriptions, in addition to a rotating that appears above the user. The middle circle is inscribed with a random sequence of Greek letters (ξοακωοξλξωκθοριξκααεϕχιοθπ,εϕχιοθπ,ξκλ), together with the outlines of the yellow and silver Pickmon at opposite ends and the Digimon's name written in katakana. After all of this pursues, a hologram of the Digimon stored on the DigiMemory then appears. Once used, the image of the Digimon on the DigiMemory becomes a silhouette temporarily.

While Shoutmon X2 fights against Ebidramon, Whamon informs the group of the existence of another "treasure" besides the Code Crown, the "memories of the legendary heroes", hoping that they will help them. After Chibi Kamemon retrieves the case containing five DigiMemories from an underwater shrine, Taiki selects Leviamon's DigiMemory and activates its attack, causing one of Ebidramon's pincers to be severed as a result and leading up to its deletion by Shoutmon X2. ("DigiMemory, Shine!") Following Ebidramon's defeat, Neptunemon summons an army of Seadramon that surround the island in order to obtain Island Zone's Code Crown. Upon Kiriha's arrival at the scene, Mail Birdramon defeats several Seadramon and afterwards, Taiki selects Marin Angemon's DigiMemory, activating its attack, causing the other Seadramon as well as Neptunemon to lose their fighting spirit. Taiki takes this opportunity to rescue Archelomon while at an advantage. ("X4, Crisis Breakthrough) In Sand Zone, Taiki chose Guilmon's DigiMemory and activated its attack to drill a hole in a rock wall, allowing him and Baalmon to pass. While in a protective barrier, Examon and War Greymon explain to Taiki and his friends that long ago, Bagramon became aware of the existence of the Real World and attempted to rule it along with the Digital World. In order to stop this, Omegamon and the others fought against him, but as the growth of human digital technology was also involved, it caused the two worlds to draw closer together. The energy produced from this caused the Core to become unstable, and the Digital World became scattered, forming the Code Crown fragments as a consequence. The resulting shock wave caused the DigiMemories to separate, with Examon and War Greymon being hurled into the space between dimensions.

Digimon Xros Loader
DigiMemory memory cards, based on the ones that appear in Digimon Xros Wars, can be used to summon legendary Digimon. They usually come packaged with merchandise, in particular the models from the Digimon Xros Wars Sofubi Digital Monster Series, which include DigiMemories based on the Digimon of a specific figure, and the Digimon Xros Figure Series, which include DigiMemories that appear in the series. They also have AR codes on the back of them that can be scanned by the Digimon X Arena.
