When performed, a flash of energy appears from Sora to trap opponents in front of him. He then says, "Donald! Goofy!" as Donald Duck and Goofy appear beside him and raise their weapons into the air together to create a large orb of energy that pulls in and traps nearby opponents. A prompt then appears on the screen saying, "Make the Limit stronger with the Special Attack button!" and a command labeled "Limit" with the triangle button of the PlayStation controller appears over Sora's damage meter. Repeatedly pressing the special input causes beams of energy to shoot out from the orb, with each beam appearing after four presses and up to nine beams appearing. Opponents that are trapped or hit with the beams are dealt multiple hits of 1% damage each until the screen flashes white, dealing 21% damage to trapped opponents and launching them with strong knockback. Sora then strikes with Donald and Goofy before they cheer and disappear, ending the move.
Trinity Limit is a recurring special technique in the KINGDOM HEARTS series in which the user uses teamwork to unleash a powerful attack. It was first used by Sora in the original KINGDOM HEARTS, in which Sora lifts up his Kingdom Key and draws in red orbs that appear from his friends Donald Duck and Goofy. He then leaps into the air and performs a back somersault before plunging his Keyblade into the ground, which summons a large energy wave that attacks all the enemies within the area. The move in SSF2 is more specifically based on the finishing attack of the technique in KINGDOM HEARTS II, in which Sora, Donald, and Goofy raise their weapons into the air and create a powerful orb of energy with beams shooting out from it as the player powers up the move.
