This may be a very stupid Question and please forgive me if it was anserwd before.
I saw the scene, where the Weapons appear. I counted them and i thought that there is one Weapon more than you can fight.
There are Ruby, Emerald, Diamond, Ultima and the Weapon that attacks Junon. Yeah good. But if I counted them correctly, there was one Weapon more appearing out of the crater.
Am I just stupid and can't count or was there really a Weapon more?
