1.5: Sora is established as the King chess piece hence the crown and the throne. He is with the Queen (Kairi), Bishop (Donald) and the Knight (Goofy). The floor is checkered to reinforce the Chess symbolism.
2.5: Xehanort is shown at the background. This is an indication that the opposing King piece is in the playing field of the heroes. He has his Bishop and Castle on the heroes side too (Ansem and Xemnas). Xehanort stretching his hands is symbolic of taking Ventus and Terra from the heroes side.
2.8: The King chess piece is making his move (Sora) alongside the Bishop (Donald), Knight (Goofy), Horse (Riku) and Castle (Lea).
