Sonic Blade
Sonic Blade (ソニックレイヴ Sonikku Reivu, lit. "Sonic Rave"), translated as "Sonic Rave" in Kingdom Hearts II, is a technique introduced in Kingdom Hearts. It allows the user to execute a number of successive thrusting attacks. After the first attack, each successive attack is activated through a prompt command.
Mechanics
In Kingdom Hearts, Sonic Blade is a Special Ability that Sora can use while on the ground against a target at mid range. It lets Sora charge with the Keyblade up to seven times. Sora is invulnerable during the technique. Selecting the Sonic (ソニック Sonikku) command from the last command bar executes the initial attack, an additional three attacks can be added by selecting the Rave (レイヴ Reivu) command each time it becomes available, and the final, more powerful finishing strike is executed by selecting the Blast (フィニッシュ Finisshu, lit. "Finish") command when it appears. In the Kingdom Hearts HD 1.5 ReMIX release of Kingdom Hearts Final Mix, the initial Sonic command, the Rave followups, and the Blast finisher are all implemented as Reaction Commands. Sonic Blade costs 3 AP to equip and 2 MP to use.
In Kingdom Hearts: Chain of Memories, Sonic Blade is an attack sleight that allows Sora to dash back and forth across the field, and can be steered slightly up or down as it is executed. The dashes are slower than in other games, allowing the player time to add up to six additional thrusts by pressing 
at the end of each dash. If used in midair, Sora will return to the ground before throwing the Keyblade. In Kingdom Hearts Re:Chain of Memories, the dashes automatically target an enemy and cover a greater distance, although they can miss if the target is airborne. Additional attacks are activated by pressing 
when prompted, but the timing for the press is stricter, and pressing at the wrong time cancels the sleight. The card combination for Sonic Blade is:

In Kingdom Hearts II, Sonic Rave is a limit that is exclusive to Genie. The limit begins with Sonic, in which Genie transforms into a giant hand that Sora uses to smack enemies several times. Afterwards, Rave transforms Genie into a rocket that propels itself into enemies as Sora rides on top of it.
In Kingdom Hearts II Final Mix, Sonic Rave is also an action ability exclusive to Limit Form. It is a limit that is equipped by default and costs 60 MP to use. It is automatically assigned to 
in the shortcuts menu. On activation, Sora performs the opening lunge attack, and up to five more attacks can be executed through the Rave Reaction Command. Afterwards, the Reaction Command is replaced with Finish to perform the final attack. If used in midair, he will return to the ground before throwing the Keyblade.
In Kingdom Hearts Birth by Sleep, Sonic Blade is an Ultimate attack command that takes up one slot in the Command Deck, has a maximum level of 5, has a normal reload time of 15 seconds, and fills the Command Gauge by 20%. If used in midair, they will return to the ground before throwing the Keyblade.
In Kingdom Hearts 3D: Dream Drop Distance, Sonic Blade is an attack command exclusive to Sora that uses two slots and has a reload time of 36 seconds. It lets the user charge at the enemy multiple times. It grants +3 to Strength and +1 to Defense when attached to a Dream Eater recipe.
