Think about it.

Kairi with a keyblade.

 

The same Kairi who is immune to darkness and anything evil that tries to harm her is instantly vaporized due to her having a princess of heart.

 

Now imagine that power combined with a keyblade. A keyblade that has the power to do anything, including destroying a building in half and summoning giant pillars of light.

 

We might not need Sora anymore due to Kairi having a keyblade. He might as well be Yensid body guard or go back home to Destiny Islands. Just make Kairi defeat Xehanort while saving worlds, and BOOM. The universe is safe. Throw a little bikini DLC and Kingdom Hearts 3 is considered a masterpiece due to having a female protagonist. Because everyone LOVES female protagonists.

 

1000/10 - IGN, Kotaku, Game informer, Polygon, Famimustu, and every single game reviewer in the world.

Princesses of Heart aren't that strong. It took 6 of them to hold back the darkness from the Final Keyhole. I doubt Kairi would be strong enough to defeat the 13 darknesses herself. She will definitely be strong but Riku and Sora have their own powers which make them powerful (Rikus control over darkness and Soras connections with other people's hearts). Plus more experience using the Keyblade.

Not OP. But she might have awesome Abilities.

Can she be able to use flowmotion, attraction flows, parkour skills, customizable keyblades, and shotlock commands?

Lol, it'd be awesome to see Kairi kick some serious butt, and I'm sure this'll be the case!  The fact that she's the only Princess Of Heart that can wield a Keyblade is a very interesting thing indeed!  Just imagine the power she'd have at her disposal once she masters the Keyblade!  I bet her powers would be on par with Sora and Riku's!  We just might see some badass moments where she swoops in and saves their skins!

 

And I really hope there's more character development for her!!!! X_X

Best... Idea.... EVAR! SQUARE ENIX DO THIS PLZ

 

On topic, I don't know about her being OP, but something tells me that her being a princess of heart means she'll have access to awesome abilities and magic. The possibilities are endless so long as the developers don't screw up...

i don't think just having a Keyblade enables you to slice through buildings. apparently that was a self-taught ability too so who knows how long it would take Kairi to have abilities like that. 

 

chances are we'll see Kairi with plot convenient abilities used only during cutscenes

She might be a Princess of Heart but that does not mean she's untouchable . We all know she's probably gonna be the main focus during the game but she can't be stronger than Riku .

Doubt she'll be in the OP Leagues with Sora and Riku, among others, even with a Keyblade and her unspecified and inexplicable plot convenient abilities as a Princess of Heart, what with being able to resist Darkness better than most people.

 

And unless she gets some desperately needed character development, she won't even stand out. It'll be like Lightning being called a masterpiece of a female protagonist, unearned and bollocks. ...wait, she was.

I do sincerely hope for moments of OP with the Princesses. I think it'd be cool to see them show off some of their skills, which they haven't really had a chance to yet. 

That'd be great if she is playable.
