Flowmotion

Flowmotion (フリーフローアクション) is a gameplay mechanic that appears in Kingdom Hearts 3D: Dream Drop Distance, Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage- and Kingdom Hearts III. It allows Sora, Riku and Aqua to traverse their surrounding environments with great ease when they interact with certain environmental elements. Using Flowmotion, Sora and Riku can jump off of walls, grind rails, leap great heights, and dynamically attack opponents.

In Kingdom Hearts 3D: Dream Drop Distance when Sora and Riku use Flowmotion, they are enveloped in a magenta aura, and they are sometimes accompanied by two orbiting lights of the same color, that trail light behind them. In Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage- and Kingdom Hearts III when Aqua and Sora use Flowmotion, they are enveloped in a blue aura.

The full set of Flowmotion commands are automatically equipped to Sora and Riku's Command Decks after Sora meets Neku in Traverse Town.

Kingdom Hearts 3D: Dream Drop Distance
When Sora awakens in Traverse Town, Neku can be seen using Flowmotion over the rooftops, using a Wall Kick off the side of a particularly tall building. After the two of them meet, Neku heads for the Second District, executing a Pole Spin, Rail Slide, and Superjump along the way.

In the Grid, when Rinzler attacks Riku and Sam Flynn on the Throneship, Riku uses a Wall Kick to knock Rinzler off of the ship's bridge.

Back in Traverse Town, Riku corners the Spellican in the Third District by Wall Kicking and Super Sliding in front of it, forcing it to switch to Sora's Side.

When Sora confronts the Spellican in Symphony of Sorcery, it leads him on a chase through a starry sky, as he Rail Slides along a sparkling trail.

Kingdom Hearts 0.2 Birth by Sleep -a fragmentary passage-
When Aqua heads toward the Castle of Dreams from the Main Road, a tremor causes the ground to collapse, forcing her to Rail Slide across a frozen river to reach the other side. She also uses Rail Slides while evading Darksides in the Forest of Thorns of the Enchanted Dominion.

Kingdom Hearts III
In San Fransokyo, Sora demonstrates and executes several Flowmotion techniques during the Shugyo. His usage of Superslide, Superjump, Pole Spin and Free Running, inspires Go Go Tomago to add similar techniques to her arsenal.

In The Caribbean, when the Raging Vulture attacks the Black Pearl, it is accompanied by numerous Vaporflies trailing colored smoke. When one passes near the Pearl, Sora uses Rail Slide to travel along the contrails, instructing Donald and Goofy to keep the ship safe while he deals with the Heartless.

Mechanics
In Kingdom Hearts 3D: Dream Drop Distance, Flowmotion is activated by pressing to Dodge Roll or Air Slide into a wall or other interactive object, or by landing on certain environmental features, such as rails or fountains. Sora or Riku will perform a context-sensitive action, such as briefly sticking to and jumping off of a wall or spinning around a pole after Air Sliding into it. Using an Air Slide, Sonic Impact, or Double Impact to transition into Flowmotion will work faster than using a Dodge Roll. During a Flowmotion command, Sora or Riku cannot be staggered, but they can still receive damage.

Once a Flowmotion is activated, it can be chained together with additional actions. The player may press to use a Superslide to travel long distances or transition to another Flowmotion-compatible surface,  to perform a Superjump that boosts the user to a great height, or  to use a Flowmotion Attack (フリーフローアタック), which depends on the Flowmotion action the player is using.

In Kingdom Hearts III, Flowmotion is no longer as potent as its incarnation in Kingdom Hearts 3D: Dream Drop Distance; however it remains a viable method of quickly moving across the map, especially early game. Flowmotion is activated by pressing to Air Slide or Aerial Dodge into a wall, or by landing on certain environmental features, such as rails. Using Dodge Roll onto these surfaces will no longer activate Flowmotion, but certain magics will now cause it to activate, such as Blizzard and Aero. Also, Sora can be staggered while in Flowmotion.

Once Flowmotion is activated, it can still be chained together with additional actions but (again) not to the extent as it could in its debut. The player may press to use a Superslide to travel long distances (equipping more will cause the distance to increase dramatically); or they may  to perform a Superjump that boosts the user to a great height, though Super Jump can no longer be chained. Flowmotion Attacks (フリーフローアタック) return, linked to, though they are now slightly different. Kick Dive is replaced with Sonic Slash, and Shock Dive is replaced with Sonic Cleave, which does not generate a shockwave.
