In Kingdom Hearts Birth by Sleep, when Ventus, Terra, and Aqua set out on their journey, they gained experience and learned new spells and abilities. The same thing occurred when Sora was introduced in Kingdom Hearts. Because of the memory alterations by Naminé in Kingdom Hearts Chain of Memories, Sora and company had to relearn their moves from Kingdom Hearts. Kingdom Hearts 358/2 Days brings Roxas and co.; having their own experiences. Because of both Roxas's and Sora's lose of memory from Kingdom Hearts Chain of Memories and 358/2 Days, both characters had to start from a blank slate in Kingdom Hearts II. Data-Sora was fresh to the scene in Kingdom Hearts Re:coded, explaining why he had to learn things the real Sora had, and Sora and Riku are forced to abandoned their self-taught Keyblade abilities when they journeyed into the Realm of Sleep. So far, there has been a logical explanation for why the player starts off with very little at the beginning of each game. This begs the question, "how will it happen in Kingdom Hearts III?" My theory is simple: Sora and Riku only learned their new abilities in the Realm of Sleep. Now that they have returned to the Realm of Light, they have to learn them for real. What are your ideas?

My theory is. It's a new game so we have to start at Lv. 1.

They're still learning new things.

This is what I would consider over-analyzing things.  

well, riku is a keyblade master and sora has the same amount of skill so they should learn new, dope moves. Like yen sid sad, they have to relearn and apply new keyblade moves with their style

My theory is. It's a new game so we have to start at Lv. 1.

 

LOL! My thoughts exactly . No reason to overthink it.

Yeah. It just is what it is.

This whole time I thought a magical unicorn came and wiped their memories before the start of every game?

Yeah, I don't think you have too worry abou it too much, they'll find some way to do it. And it's not like we're starting from lvl99, it's always lvl1

 

And your theory makes sense, I think they'll go with that.

I think Nomura takes lvl 1 too seriously. As gamers we should know that its a mechanics thing and not necessarily meaning that Sora and Co are weak. But to answer the question they will probably be given some degree of power. Something such as the flow motion abilities of 3D that seemed to simulate the feel that they aren't weak while still being weak would work well for KHIII. 

How about the enemies start off difficult to defeat in the beginning, and as we "level up" they become easier, and then they get harder again.

 

Oh that doesn't make sense D:

*Uses video game logic*

 

Ends game with all abilities. Next game starts all over.

I think what you said will happen.
