KH1 - Ursula and final Ansem.
(Re:)COM - Probably Ansem again. (Though for the looongest time it was Marluxia. xD)
KH2 - Last part of the Xemnas fight, the Terra fight (FM+) and the Roxas fight (FM+ again).
Days - Parasite Grave. Oh god parasite grave. D: I forget its English name but that one boss in Halloween Town. That special mission still gets me pissed off even just thinking about it. XD
BBS - Final boss in arena mode. :/ And I guess the secret boss sice I never did beat it but I also never gave it a good try.
All in all, I still rage when I think about Parasite Grave so let's give full honours to that one as least favourite boss. xD;
Oh, it seems that I forgot to say the bosses I hate in the Kingdom Hearts
series.
Re: CoM: It HAD to be Axel (The 2nd time.) Though I like him in 358/2 Days,
he's annoying in Re: CoM. He KEEPS warping around like an idiot,
and is extremely fast. That fight alone took me 10 tries.
KH 2: No words to say about this. It HAD to be Demyx.
He's a water sitar jerk. His countdown is so, so, so, so ANNOYING!
He took me 7 tries.
358/2 Days: Dustflier is ANNOYING with his SUPER HIGH defense
and attack. Its friggin' damn fireballs keeps killing me.
It took me 15 tries to beat the hell outta it.
Birth by Sleep: I won't play this game until it releases in the USA.
And also, that "Parasite Cage" is Leechgrave. It used to be
my most hated boss, but after playing other KH games,
I realized that Leechgrave is easy.
Days The Heartless Eater by a mile. I nearly didnt play to the end because of it.
The "Heartless Eater" is also known as Leechgrave.
Anyways, it's not tough at all if you have a Keyblade with high attack.
Well, if we're going for optional bosses too, then....
KH: Phantom. I never could use my magic effectively and efficiently enough. Otherwise, I'd have to say the first Ursula fight. Once again for magic reasons.
CoM (Surprisingly, I'm the reverse of a lot of you. I played the original, not the remake.): The final Vexen fight. I hadn't collected enough Fire Spell cards, and, well, with that bloody shield he has.....
[/SPOILER]
The original Chain of Memories is just too easy that even a
4 year old can beat it. The remake is much harder.
Vexen isn't all that hard - in fact, he's easy.
Dustflier wasn't particularly hard for me--it takes absolutely forever if you don't have Zero Gear equipped but if you do have it and a few sense panels, it goes down fairly quickly. You just have to watch its patterns and make sure not to do what I did very often, which is accidentally glide out of the area while gliding out of the way fffffff.[/font]
It was hard for me - but there's one thing I disagree...
It's that beating Dustflier doesn't require the Zero Gear,
because I think it will be easier with the Ultimate Gear.
CoM: I only got to play the original. >: Silly, silly Europe. Anyway, I have more trouble with beating the Heartless to get out of Monstro's stomach than I do with bosses. XD; I found that game kinda easy, no-one gave me much trouble except for Captain Hook.
Days: That spiky boss in the Coliseum - I can't remember the name off the top of my head, but that was the only thing I had a lot of trouble with.
KH2: Demyx. Darn countdown. >: Luxord and Xigbar were also iffy when I first fought them, but now I've played it so many times I'm used to what goes down. XD;; Oh, and Sephiroth is a beast too. -w-;
BbS: Uhhh... I WANT THIS GAME TO COME OUT IN ENGLISHHH. D:
I agree with you. Demyx is indeed annoying with his damn water countdown.
I wish Birth by Sleep will get released in English as soon as possible.
And by the "Spiky Thing" in Days, do you mean the Morning Star?
If it is, then it would be weird. Spike Heartless Family HAD to
be the easiest bosses in Days.
It's too bad that you only got to play the original Chain of Memories instead of the remake. If you had played the remake then you will think either
Axel or Marluxia is annoying.
