Sonic Blade

Sonic Blade is one of Sora's special abilities in Kingdom Hearts, it is learnt 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 ability, 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.
