True Sephiroth was pretty cool as a story battle. I liked Ruby WEAPON, it gave that terror of, I see something small and red let's crash into it and see what happens. Of course it turns out to be near the size of the golden saucer, I can barely hurt it and of it kills me really quickly. For similiar reasons I like Emerald WEAPON because when I first fought it I thought the objective was to survive for twenty minutes. So I attacked it, healed, got killed. Then went back- after a ton of attempts and slowing down the speed of the battle I lasted 20 minutes and... got game over. After I set up my characters decently and got a golden chocobo those two were both too easy. I liked Carry Armor too because it was one of the harder bosses on the game and all the Reno fights cause he's cool.

Why should this be in the Advent Children forum? Everything mentioned so far has been from FFVII.
Actually if the starter of this thread was talking about the motorcycle fight in AC (which makes more sense as it was more interesting) and the Sephiroth fight in AC then this could have gotten put in FFAC forum, however that would have given much fewer fights to choose from. I'm just saying what he said seemed reasonable.
