Trinity Limit

Trinity Limit (トリニティリミット) is a special technique that appears in Kingdom Hearts, Kingdom Hearts Final Mix, Kingdom Hearts: Chain of Memories, Kingdom Hearts Re:Chain of Memories, Kingdom Hearts II, Kingdom Hearts II Final Mix and Kingdom Hearts Birth by Sleep. Trinity Limit is a technique that uses teamwork to unleash a powerful attack.

Mechanics
In Kingdom Hearts and Kingdom Hearts Final Mix, Trinity Limit is a Special Ability. Selecting Trinity from the last command box causes two red orbs to emerge from Donald and Goofy. The orbs will come to Sora's Keyblade. Sora then executes a few powerful flips and leaps, then does a back somersault, planting his Keyblade into the ground, summoning a large energy wave crushing all enemies down within the area. The more MP Sora has during the executing period, the more powerful the finishing attack becomes. It costs 5 AP to equip, and uses all of Sora's, Donald's, and Goofy's MP, requiring at least 3 bars of MP to activate.

In Kingdom Hearts: Chain of Memories and Kingdom Hearts Re:Chain of Memories, Trinity Limit is an Attack Sleight that has the same appearance as from Kingdom Hearts and Kingdom Hearts Final Mix. It is a very powerful attack that deals heavy damage, capable of clearing a whole field of enemies.

In Kingdom Hearts II and Kingdom Hearts II Final Mix, Trinity Limit is a Limit with no resemblance to the previous versions of the ability. It has two forms: If Trinity Limit is used with Sora, Donald, and Goofy, the command menu changes to: After each command is executed, the corresponding button command changes to Begin Combo. Selecting it activates the finishing attack, during which Sora, Donald, and Goofy raise their weapons together and unleash a storm of energy that hits all enemies in range. The pose Sora, Donald, and Goofy take for the finisher is similar to their pose when activating Trinity Detect in Kingdom Hearts. To attain as much damage as possible, the Begin Combo command should be used only after all three attacks are performed consecutively. If Sora is without either Donald or Goofy, or both, he only performs a solo version of the Break attack combo. Sora will attack ten times, with the first nine attacks building up to a final, lunging blow that pierces the enemy with a powerful finishing move. This is the only limit that can be used without any party members. It costs 5 AP to equip, and like all Limits, uses all of Sora's MP. The overall damage and efficiency depends on Sora's overall status, including Drive Form levels.
 * - Major Drive (Sora, Donald, and Goofy fire a barrage of Drive Orbs)
 * - Ultima (Sora, Donald, and Goofy summon a cluster of fireworks)
 * - Break (Sora, Donald, and Goofy deliver a series of powerful mid-air slashes)

In Kingdom Hearts Birth by Sleep, Trinity Limit is an Advanced-class Friendship Command that takes up one slot in the Command Deck, has a maximum level of 1, and a normal reload time of 40 seconds. If used in the Mirage Arena, up to two other players can join in on the attack. It becomes stronger by pressing at the prompt. Its appearance combines the symbol from the Kingdom Hearts version and the pose from the finishing attack from the Kingdom Hearts II version of Trinity Limit.
