Reaction Command

Reaction Command is a feature introduced in Kingdom Hearts II. At certain points in the game, a reaction command can become available to the player, and these are executed by pressing the triangle button. Doing so often offers great benefits to the player, and sometimes are the key to continuing in the game.
