I summon Bahamhut to use mega flare, then have all of tyeh peeps ftrom Mysidia use flare. IF they're as awesome as me, it should be enough to kill anything. >:P
I break it apart, then I order it so it is the form of a brick golem. Then I use animate to make it walk, talk, and attack. Then I mount a machine gun that the brick golem can use
