What does that matter again?
No reason to mention this, but I'll do it anyway, Cloud and Sephiroth (and undoubtedly several others) can also jump incredibly large heights and distances, slice through buildings, move at incredibly fast speeds, and defeat massive armies and ridiculously powerful enemies.
It's just like watching an anime like Dragonball, YuYu Hakusho, or BLEACH, each time a new big bad comes along it's as if the main character's level has been reset back to basics (although with a few sweet new moves in tow).
