Friend Card

Friend Cards appear in Kingdom Hearts: Chain of Memories as a type of playing card which summons an ally of Sora or Riku to help them during battle. They can be identified by their green borders, which they share with Item Cards. Friend cards behave identically to Attack, Magic, and Summon cards, but unlike the other types of playing card, they cannot be collected, and are instead randomly obtained during battle, and disappear when the battle is finished.

As in Kingdom Hearts, these allies generally cannot be used on all worlds. Each friend summon can be upgraded to more powerful levels by stocking multiples of that friend card, though they can also be used in various combinations with other Friend Cards, as well as Attack, Magic, Summon, and Item Cards to perform different spells and summons unavailable in the other games. Many of these new combinations are Kingdom Hearts versions of traditional Final Fantasy spells like "Terror" or "Teleport".
