Oblivion has probably been the best overall so far, in terms of strength and difficulty in obtaining it.
the one from KH2 u get after Axel kills himself was pretty cool-looking but not as strong as I wouldve liked it to be

i like metal chocobo u get it from cloud how hot is that lol and it looks hot too

I fell in love with Oblivion. I'm getting a real one too!

I also love the designs of both Ultimas, which I spent weeks getting. Very much worth it.

Oathkeeper is pretty too.

I hate Photon Debugger. It's ugly, has a dumb name, and USELESS!

Ultima Weapon for KHII was pretty nice and it had the longest width of any other keyblade in the entire game, but I prefer the Fenrir, even if it did decrease your combo by one. It was nice to have a Keyblade that actually looked like a blade.

I'd go with Fenrir and Ultima Weapon.

Fenrir was epic good and also, I didn't look like a dorky key. It looked more like some kind of blade..

i like the oathkeeper because it is beautiful

ahh yes the fenrir....had to be the best blade of all...

ya, for whatever reason none of the NPC's can actually DEFEAT them, and the pumpkin one with the oblivion were my favorite. but ultima weapon and fenrir were the best

you know the final mix of kh1? yeah i liked the one winged angel keyblade in that one.

I've always liked Oblivion.I dunno why,maybe because of it's name.It's very noticeable.

Well for for the first kingdom hearts it would definitely have to be between oblivion or ultima weapon. For the second though, it was all the way fenrir.

I love metal chocobo, But in KH II I really hate Hidden dragon and monochrome!!
