Kingdom Hearts II This heartless trouble im having

But he wasn't exactly stealing Riku's body so he could have a physical form (after all, we saw him in the beginning of the game, and right before he possessed Riku). He was using Riku's body so he could obtain the Keyblade and release Kairi's heart so the Keyhole would be complete. He couldn't have done that without him, since Heartless can't use a genuine Keyblade (I don't think it ever says this upfront, but Xehanort's Heartless says "The heart that is strong and true shall win the Keyblade.", and since the Heartless don't have hearts, then they can''t use it) . If Mickey didn't say that "Ansem" was actually a Heartless, I probably wouldn't be debating this with so much confidence XD I just can't see the writers of this game have Mickey say in a later game that "Oh yeah, I told ya that 'Ansem' was a Heartless, but I was sorta lying. Ya see, he's actually a ---". It's too much of a weird thing for them to change after saying straight up it was something else. And at that point, nobody would really care, since it would have no bearing on the plot. The holy s*** factor in KH2 was that since he was a Heartless, then there was also a Nobody; but now both of them are dead.

I don't remember what he said in the GBA version, but it was probably more or less the same as what he said in the PS2 version. This is the exact quote: "He held on to his feelings even as a Heartless. And there's only one other man who's been able to do just that."
