It took me forever to beat Demyx and Xigbar. Demyx wouldn't stop using his water, Xigbar just keeps teleporting and shooting me. It got pretty annoying. What about you guys?

I died so many times in the Demyx fight. Stupid water clones!

Demyx, and if you also allow the Final Mix+ bosses to be chosen: Roxas.

Xaldin was pretty hard to beat, and every now and then while fighting Xigbar, I would go into Anti-Form ('cause I forgot to turn off all the Auto abilities...), but I would have to say the boss that took me the longest to beat would have to be the final battle with Xemnas.

 

(Yes, I know, that one is the final boss; he's supposed to take a while to kill)

the one that took the most was demyx and xigbar:@

For me it was Demix and Xigbar too,because I didn't got to Xemnas yet,I think Xaldin wasn't that difficult.

the one that took the most was demyx and xigbar:@

 

Yeah those bums took me forever!!!!!!!!!!!!!!!!!!!!!!!

Hmm larxene

xailden omfg wuz he freking annoying or wut!!!!! >.

Oh yeah, Xaldin was really hard, i forgot him.

Demyx and Xalden. If we include Final Mix+ then Lingering Sentiment, Roxas, and Marluxia.

Xigbar, but it was worth it because i unlocked final form 4 times and got to keep it. But i battled him like 17 times.

Xaldin for some reason I kept losing

Terra he kill me 10000 times

he is very strong

Xigbar was the hardest for me!

Well Hercules is out og the running, 12 seconds for him, and so is Demnyx he was like 7 minutes, and xigbar no he took me 5 (All on proud) So I will have to say that the longest boss for me was... Sephiroth.

P.S I was doing a vid for Youtube on beating Sephiroth at lvl 36 no hacks, because I own no hacks, but he killed a bunch of times so I got to lvl 50 (Proud Mode) and killed him! So Sephiroth definitaley, Demnyx and Xigbar are so easy ppl. (Well when I first did it it was hard but they get easier everytime ya do it)

yea Sephiroth, Demyx, Xaldin

Sephiroth took me the longest

Xaldin took me kinda long to beat

Demyx was just plain annoying

oh and in FM+ Roxas, Larxene, Terra

Terra just owns he kileld me like 40 times it i tried using kingdom key couple of times to see if i get lucky.

Roxas was fun but his giant lazer things were kind of annoying and it kept getting me owned

Larxene was more annoying that Demyx and that laugh its still echoing in my head!

Xaldin, he alway enter in his desesperation move, and I needed a lot of mickey help(I was playng with only kingdom key)

I would say that Xaldin was the longest boss for me to defeat.

Heh for me Xaldin was easy compared to Xigbar.

they were all easy but Xaldin pissed me off as it was annoying hitting him without him flying off... Xiggy I beat in like a minute at level 50... he didn't even use his mega attack thing (muahaha =P). Demyx was quite easy as long as I kept spamming reaction commands when he played the Sitar and summoned the water things. I haven't got as far as Sephy yet as at level 60 I would get creamed. Being British = No FM+ so no Terra, Marluxia, Larxene or Roxas =[

the hardest bosses for me were xigbar, sephiroth, and demyx (second battle, the water clones he summoned annoyed me for it was too short of a time limit!!!) though I belive everyone else was easy...I think...

demyx: just because of the stupid time trials

xigbar: i would always die by that rapid fire thing

xaldin: to much invincible stages

siax: to hard to hit him with the beserker

sephiroth: the reaction comand, one winged angel, and meteor

demyx and xigbar r both really and i mean really easy just stay from them when theyre attacking attack back when u have a chance use ur forms if u need to or if necassery, but the only time i had problems was on proud mode demyxs time thing runs out way to early and xigbar was accually easy he just did one to many attacks/shots thats alll

I hated Xigbar and Xaldin. I started over on Proud mode to get the secret ending.

id say the hardest bof for e to beat was sephiroth still cant beat him at lev 87 and longest battle was Xaldin
