In every game I ever play there is always one section I find way harder than the rest, and once I'm through that I pretty much breeze through the rest. But on the subject on FF7, which boss do you always have a bit of trouble getting past?

Mine is Schizo, the annoying two-headed thing on Gaea's Cliff that spits fire and ice on you. Normally I tend to be okay if I can manange to equip all the proper elemental defensive stuff, but even then it always poses a challenge because its attack pattern is quite unpredictable: Never possible to tell when it's gonna get its next attack (I swear it's sometimes getting some in when it shouldn't be able to.) So now, on my current save, which is initial equipment and no additional Materia, every single one of their attacks does at least 900 damage and I'm really struggling :P Having Yuffie on Fury so that every single attack fills her Limit gauge and enables her to use Clear Tranquil is somewhat helpful, but not much.

Go on, which boss gets on your nerves?
