Secret Trailer Summary

In the opening of the secret trailer, we see an unknown man in armor standing on top of an object. He seems to be standing triumphantly, holding his massive keyblade behind him. He then seems to notice something from off screen and jumps down. As he walks away, the object he was standing on blows away like it was dust. As the Enigmatic Soldier (E.S.) walks to the middle of the crossroads, the Female Soldier (F.S.) appears from another direction, along with the Blonde Haired Soldier (B.H.S.). Three keyblades lie there: Kingdom Key, Way To Dawn and Mickey’s Keyblade. The E.S. picks up the Kingdom Key. The F.S. picks up Mickey's Keyblade. The B.H.S. picks up Way To Dawn. They all then notice a shadowed figure off in the distance.

The three knights face down the mysterious figure off in the distance. The figure becomes clearer as it drew closer to them. It is an Unknown Elder Mage (U.E.M.), who then splits himself into two beings. By doing this he creates the Dark Soldier (D.S.). The B.H.S. starts to move towards them, only to be halted by the E.S. who goes after them himself. As he dashes towards them, the U.E.M. casts a spell that lifts a large wall of earth to block his path. He then lifts himself and the D.S., up with another wall of earth. As the E.S. watches them rise up, the D.S. jumps down and casts a powerful thunder spell on him. This leaves his armor badly damaged, engulfed with small flames. The B.H.S. then runs after the D.S. into battle, with the E.S. soon following him. The U.E.M. then casts another spell, where many keyblades start to move and attack in waves. The B.H.S. continues to chase after him, while the D.S. casts blizzard spells to keep him off of his trail.

The F.S. tries to keep up with them, but then notices the wave of keyblades. The D.S. jumps on top of them and rides on the blades, casting powerful blizzard spells as the two knights try running away. The D.S. has the upper-hand when he rides on top of the wave of keyblades, which hit the B.H.S., but he quickly regains balance. When D.S. touches down, the B.H.S. tries to get a hit in but is simple knocked away. The F.S. uses this time to cast a thunder spell, but the D.S. avoids it and rides the keyblades off once again. The E.S. tries to run from the wave of keyblades that have been chasing him, but accidentally falls off a cliff in doing so. He attempts to get a grasp by stabbing his keyblade in the wall, however the wave of keyblades blows off the part of the cliff where he was on.

The F.S. notices that the E.S. is falling off of a cliff. With her distracted, another wave of keyblades strike her from the ground below her. The force lifts her up into the air and then she crashes back down to the ground. The F.S.'s helmet is obliterated from the wave and her face is revealed. The B.H.S. runs to check on her. She quickly casts reflect on the E.S. upon her harsh landing, seeing that he to is being assaulted by a wave of keyblades. She's breathing hard, exhausted from the battle. As the wave of keyblades attack the E.S., reflect reaches him and forces the blades to go away from his body. Yet another wave of key blades assault him, he is safe though with reflect. The blades push the E.S. up to the U.E.M., then the reflect ball holding the E.S. explodes in front of him. The F.S. stays behind as the B.H.S. goes after the two threats.

The E.S. falls and lands not to far from the U.E.M. As he stumbles trying to get on his feet, he begins to run towards the U.E.M. The U.E.M. strikes back at him with his own keyblade. He also manages to knock the E.S. back and freeze his entire left arm. The B.H.S. attempts to strike the U.E.M. while he is distracted. But he just teleports behind him and grabs ahold of his head. The E.S. tries to run and help him, but is hit by another wave of keyblades and is thrown off the cliff. The U.E.M. tightens his grip, crushing the B.H.S.'s helmet. The F.S. rises up, and sees the B.H.S. in the hand of the U.E.M. The D.S. reappears and stands next to the U.E.M. A piece of the B.H.S. helmet breaks because of the tight grip, revealing his right eye. The two look at each other in horror as the B.H.S. is frozen alive.

The U.E.M. freezes his entire body and heartlessly throws him off the cliff. Pieces of his keyblade and suit break off as he falls to the ground. Before he touches ground, the F.S. runs to him. She barely manages to get to him in time. She holds him and looks into his face. His eyes move, showing that he is still alive. The U.E.M.'s keyblade then vanishes and he creates a dark ball of energy in his hand. He then launches it up into the sky. He looks on with the D.S., smiling. The sky suddenly opens up revealing a heart-shaped moon. The F.S. clutches the frozen B.H.S. as she looks on in awe at the sky. When the E.S. finds the strength to get back up from the fall, he removes his helmet to reveal his face. He sees Kingdom Hearts in the sky. As he looks towards it, the screen violently zooms in on him. His blue eyes suddenly turn hazel.

Mickey appears from a hill, quite a ways from the battle. The mouse walks to the edge of the cliff, and watches as a heart-shaped moon appears from the sky. He dons a new black outfit and is wielding the Star Seeker Keyblade. He looks on with a rather serious expression as the trailer ends.
