You know, simply quoting that rule isn't sufficient as specifying that, as for starters you don't even state which characters are on each side, or anything like that.
Still enough since the strongest person from the FF7verse is Chaos and Omega.. and Id w/Weltall can produce that level of destructive power with ease. Now add that Graf, Myyah and Elehayym in Omnigear are hovering at or near his power, along with G-Element, Seibzehn, Yggdrasil, Excalibur, and Lightforge and there's some massive firepower that FF7 cannot overtune
