Those Bangaa become unstoppable in the later levels when you have the items giving you skills to self destruct for more damage than any enemy(besides bosses) in the game has- then resurrect automatically in one turn(accesory item/life resurrect magic).
Eh, 2 player link cable battles were too easy.
There was no true 1 on 1, so my bro and I left one enemy alive, then I did the Bangaa self destruct on him(and his one other teammate) and he was like "No fair, how did you do that! My main character has the highest attack ever! He can't lose."
Ah yeah.
