When performed, Sora lifts his Keyblade into the air to create an orb that traps opponents that make contact with it. If Sora traps any opponents, he will then attack them with a barrage of quick spinning strikes in place with his Keyblade. As he slashes, he can also move with the opponent in any direction that the player directs him in. After the barrage of slashes, he will disappear and then reappear in front of the opponent to deliver a final strike that knocks them away with high knockback.
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 Keyblade 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. In KINGDOM HEARTS II, the move has a second variant that is performed solo, in which Sora instead delivers a series of ten powerful midair slashes, with the final slash being a more powerful lunging blow that pierces the enemy.
In SSF2, the Final Smash mixes both variations of Trinity Limit: at first it uses Sora's group Trinity Limit where Sora lifts his Keyblade into the air, and then it transitions into Sora's solo Trinity Limit where he starts unleashing powerful strikes onto the opponent. However, unlike in the original game, Sora performs the first part of the move by himself.
