Teamwork

Teamwork (ユニゾンアスリート) is a technique that appears in Kingdom Hearts II and Kingdom Hearts 358/2 Days. It allows the user to execute a series of charging attacks. It is a signature of Goofy.

Mechanics
In Kingdom Hearts II, Teamwork is an action ability exclusive to Goofy. It is a limit that costs 3 to equip and all of Sora's MP to use. The first attack is spread over two commands, identically named Knocksmash (ノックラッシュ). In the Reaction Command slot, Knocksmash causes Goofy to throw his shield in the air, while the Knocksmash in the Attack command slot allows Sora to hit the shield at an enemy, like a baseball. After five attacks, both slots of Knocksmash are replaced with Duo Raid (ツインレイド), which allow the duo to throw their weapons at enemies simultaneously. The finishing move, Cosmo Boost (コスモブースト), has Sora launch Goofy like a rocket, heavily damaging enemies he hits. While the limit is active, Sora cannot move freely, and cannot attack other enemies.

In Kingdom Hearts 358/2 Days, Teamwork is a Limit Break. It allows Goofy to repeatedly launch himself like a rocket over short distances, dealing heavy damage to enemies. Holding charges the attack to provide greater distance. During the Final Limit, the attack can be charged further, increasing its acceleration, distance, and damage.
