In Kingdom Hearts Re:coded, Sonic Arts is an Overclock ability. While active, Data-Sora gains a completely new set of basic combo attacks. Each attack of Sonic Arts is weak, but is capable of dealing multiple hits per attack, and is much faster than Sora's average combo attacks. The attacks are also more chaotic, making them effective when dealing with small or compact groups of enemies.

The air-combo for Sonic Arts-equipped weapons is similar to Leviathan's combo in Kingdom Hearts 358/2 Days. The ground combo finishers are quick Zantetsuken-like slashes, while the air combo finisher resembles Hurricane Blast.
