My brother introduced me to the idea of this group; while it's not necessarily the best group possible, it's my favorite for use in the game.

Umaro (w/Rage Ring - does his own thing without any need for human interference)
Mog (Set him to dance, and he's off on his own for the rest of the battle)
Gau (Start up your favorite rage, and he's set to go too)
GoGo (He can dance or rage as well)


There are obvious problems such as with not being able to heal the party, use life spells, etc...but all in all I've found this group to be highly enjoyable. Especially if defeating a difficult boss with them. Just sit back and say, "Yep, those are my BOYS!" Also, most of Mog's dances and many of Gau's rages will do things that heal the party anyhow.

Perfect for a lazy bastard, like me.
