He already has twelve hims; Sora was gonna be the thirteenth. It didn't work, though; I stopped him from getting Sora.

I dunno his first plan; he did something before running into my world. But one of his plans was to have the heartless take over worlds so that he could use the keyblade to gather hearts and capture them until there were enough to make Kingdom Hearts. Or a way to get to Kingdom Hearts. And his Heartless piggybacked on Maleficent's whole plan to gather the seven princesses of heart and making a way to Kingdom Hearts that way. Sora and Riku and company - the King, yours truly, Namine, Kairi, yanno, people, managed to stop those things, but it was close.
