Hardest boss huh? The first time through I had a hard time with the Red Dragon & the Demons Gate in the Temple of the Ancients. The 5 warriars of the Pagoda in Wutaia was difficult for me too. I thought Emerald was easy, I had a harder time with Ruby.

well i thought that ultima was annoying bascially because you hade to run after it but then again safer sephiroth was annoying to

If I play FF7 again, no boss would even hold a candle to me now that I know all the little tricks and strategies.I was just stating that these bosses were hard the first time around.

I know now that you can stop Ruby for the whole fight, but I didn't know that the first time through, that's why I said she was harder.

None. it was all too simple. No regular boss could match my strength and power. i did have a little trouble with the weapons and afterwards...cakewalk

There were several annoying bosses, but some of the harder ones were probably the materia keeper and the demon wall, but I can't remember what I found hardest. But I was always ahead level-wise, so nothing was too hard.

First time I ever played the game I found the Guard Scorpion fairly hard. Don't laugh! I never took note of Clouds warning and always got raped by its Tail Laser

But more properly would definitly be the Materia Keeper. That guy is a nightmare if you don't know what your doing. Simply set-up Big Guard, hit it with Ice 2 magic and Limit Breaks, healing and recasting Big Guard when necassary and watch the bugger go down! (Not forgetting to learn Trine either )

Other notable mentions are Godo (especially at lower levels), Demons Gate can be abit of a basterd at times, and even Dyne if you haven't been using Barret all too much (his two attacks in one turn can really screw you over if your weak!). Other than that its not really much else.
