Sonic Blade

Sonic Blade is one of Sora's special abilities in Kingdom Hearts, it is learned after Sora defeats Cerberus the first time and after he comforted Cloud, which Cloud in return grants him this ability. Although it is listed as one of Sora's special abilities, Cloud is also capable of executing a stronger version of Sonic Blade. Later, several forms in Kingdom Hearts II, have similar ability, such as Over the Horizon and Sonic End. Sora can also execute Sonic Blade in Kingdom Hearts II: Final Mix through Limit Form.

Sonic Blade AP cost: 3 MP cost: 2 Description: A fast forward lunge where Sora runs past and damages enemy in range. This is also a magic based attack. Effect: When close to an enemy, the command table's last box will appear the word Sonic Blade (provided you've equipped it) by selecting it Sora will make and fast forward pierce on the closest enemy in range.
