I am dying to hear how they will kill a single Huitzil, let alone Pyron. haermm
Huiltzils alone can vape cities with missile barrages, are made of very durable metal, have a plethora of weapons, are able of flying at fast speeds(In the supersonic range), and are fairly strong.
Shit, it only took like one hundred to render the Dinosaurs extinct.
Sephiroth can use Sin Harvest Angel which brings your health down to 1, and magic to 0. Genesis would probably lose. Cloud wold use the move that he used to beat Sephiroth in Advent Children. Zack would lose but he would stand up longer than Genesis. Sephiroth by himself could beat Pyron. This is no challenge.
