Bring back every villain Buffy's ever faced! I mean sure she outdid every one of the lot when they were alone, but to team them up and unleash them upon her would have been overwhelming.The First Evil had the power to bring back anyone or thing from a Hell dimension (cause it brought Angel back no prob). It just seems like it would have made more sense to reunite these demonic foes that knew Buffy best. Over the course of seven years each of them were able to calculate her weaknesses and for the most part exploit the hell out of em. Most of the time Buffy wasn't able to beat them back without her friends.But to unite all 6 and pair them up with Caleb could have really tore her up. Plus I'd have loved to see how she would have handled the Master's return. The big bad that arguably scared her the most had to have been him. Although one thing that always seems to occur when big bad evils join up is ego trips and conflict. I can see Glory raising a ruckus, and The master probably wasn't used to taking orders. Although if anyone could have united them it would have been The First and Caleb. I guess who knows what might have been and unless the First unleashes a new kind of Armageddon on Angel, I guess we'll never know for sure.

LOL. That would of been great, Mr. J. And I have to agree...I don't think The Master would take orders very well, hell, I don't think Glory would either! She'd cop a serious attitude!
