Here we have another final boss theme, this one from the final fight against Xemnas in Kingdom Hearts II. Quite a long piece, it is nevertheless excellent from the first minute to the fourth, gradually increasing in both tempo and volume before slowing down once again, befitting the tense and hectic nature of the battle it is scoring in perfect fashion.
5. Ventus (Kingdom Hearts: Birth By Sleep)
Resembling both Sora and Roxas in terms of style and personality, Ventus, one of the main characters in Birth By Sleep, isnt exactly the most original or interesting of characters. His theme, however, goes a long way to make up for his dullness, featuring tragic undertones and some beautiful piano elements.
4. Riku's Theme (Kingdom Hearts II)
Throughout the series thus far, Riku has undergone strong growth, but remains an enigma, with his good intentions sometimes countered by the dark nature of his actions. This theme is similarly mysterious, making it an excellent accompaniment to the character, about whom the player does not get complete clarity until the end of the game.
