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 Super Jump 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.

Mechanics
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.

Once a Flowmotion is activated, it can be chained together with additional actions. The player may press to use a Burst of Speed to travel long distances or transition to another Flowmotion-compatible surface,  to perform a Super Jump 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. When you finish a boss, a portal, etc, using Kick Dive before you begin to do the shockwave will make the finish quickly vanish.

Air Sliding tends to allow for an instant transition into Flowmotion, while any Dodge Roll-type command only allows so during the final few frames of the command's recovery; in short, activating Flowmotion is faster with an Air Slide than with a Dodge Roll command, and also works as fast with both Sonic Impact and Double Impact alike.

Any form of Flowmotion also prevents the user from being knocked out of it, allowing for easy interceptions in the style of Super Armor in terms of being immune to flinching; but due to this rule, they still take the usual amount of damage or status effects during Flowmotion regardless, which can lead to untimely deaths during it.
