In Kingdom Hearts, Trinity Limit is a Special Ability. Selecting Trinity (トリニティ, Toriniti?) 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, 1 AP in Kingdom Hearts Final Mix, and it uses all of Sora's, Donald's, and Goofy's MP, requiring at least 3 MP to activate.
In Kingdom Hearts Chain of Memories, Trinity Limit is an attack sleight that has the same appearance as from Kingdom Hearts. It is a very powerful attack that deals heavy damage, capable of clearing a whole field of enemies. The card combinations for Trinity Limit are:
After each command is executed, the corresponding button command changes to Begin Combo (コンボスタート, Konbo Sutāto?, lit. "Combo Start"). 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.
In Kingdom Hearts Birth by Sleep, Trinity Limit is an Advanced-class Friendship Command that takes up three slots in the Command Deck, has a maximum level of 1, and a normal reload time of 40 seconds. When used alongside Terra, Ventus, or Aqua, as in the battle against the Trinity Armor, they will join in the attack. It becomes stronger by pressing at the prompt.
In Kingdom Hearts III, Trinity Limit is a Situation Command that allows Sora to defeat Xehanort. When using Trinity, Sora, Donald, and Goofy raise their weapons together and perform a move similar to the Kingdom Hearts II variant, then the red beam is charged to the target while being enhanced by the blue and green beams.
