Whoes the hardest boss?

Who does everyone think is the hardest boss in the game?
I was wondering because I always find Sephiroth very hard to defeat and Ansem really easy to defeat.There are also all the other bosses like Kurt Ziza and the Phantom at the clocktower.

for some reason i found the 2nd riku fight at Hollow Bastion really hard! i give up and didnt go on KH for ages then i went back on and defeated him! And the phantom fight is hard too.

i think the game is made such that sephiroth would be the strongest boss.some might think otherwise,and i have an explanation for that.

it's just that,through time,as people saw how difficult sephiroth was,they started making guides with total focus on sephiroth.so when other people saw these guides,sephiroth seemed easier because they know what to do,while the other difficult bosses without focused and dedicated guides (kurt ziza,clock tower phantom,etc.) seemed a bit harder.there are more people who fully studied sephiroth's actions than people who fully studied the other bosses.

see?if you know what to do,basically everything gets so so so much easier.

Kurt Zisa is kinda difficult, Phantom requires patients and Sephy is hell.

Of the three I failed to beat Sephyt as of yet.

In optional bosses i thought that the Phantom and Sephiroth were tied, i had a heck of a time beating them. For non-optional bosses i thought the first Ursula form was hard (just because it took me a while to figure out what you should be attacking in that fight and when).

I hope you guys don't laugh at me.... but i find the 2nd Ansem fight on the fake Destiny Islands thing pretty hard. You know the one where he is darting at you with the Guardian guy. Well, i always find that hard. The last Ansem fight is really easy compared to that!!! :)

That Riku one, ya know, the hard one.

Kurt Ziza is pretty hard:)

I found the Ice Titan pretty damn hard, but not as hard as Sephiroth.

I'm sorry i don't agree Ice Titan is easy and yes Sephy is hard:)

I would say, they all have a pattern. If you know the pattern, you beat the boss. So they are all supremly easy.

Sephy after one Sin Harvest when he is superfast is preety un predictible:)

So? Slight unpredictability. You know he is unpredictable, so therefore he is predictable.

Back on topic, i think Rock titan is Far to easy.:)

I have never been hit by him.
