Ruby Weapon

The most difficult boss in Final Fantasy VII. This is not the final boss, but rather an optional boss which has so much HP, the stronget summon in the whole game, which can do 100,000 damage every time, takes about a hundred times to defeat this boss. Ruby Weapon is a huge monster almost unbeatable which resides in the sand around the Gold Saucer in the later discs of the game. If you do not know how to beat this boss, you have no chance whatsoever. Its attacks wipe out your party in a matter of only a few turns. Characters with maximum stats even, have no chance of beating him unless they have a specific routine for pummeling him.
