In Kingdom Hearts 3D: Dream Drop Distance, Dark Barrier is a defense command exclusive to Riku that can equipped in the place of a Block-type command, which can overlap with a Dodge Roll-type command. It generates a spherical barrier around the user when the player presses . It may be used in midair, causing Riku to briefly hover while the barrier is active, and overlapping with Air Slide. Dark Barrier grants +3 to Defense and +30 to Dark Resistance when attached to a Dream Eater recipe. The barrier's blocking duration is extended whenever any attacks come into contact in succession.
