Ok, I see some flaws here.

Cloud did not cause anything. HE WAS a low ranking shinra soldier. ZACK was the SOLDIER First Class that accompanied Sephiroth to Nibelheim.

There was some mosters that could paralyze in FF7. I can't exactly remember what they were called but I remember fighting them in the Batlle Arena. They use an attack where they like blow leaves or something on you. You fall in to paralysis for a low ammount of time. You may not believe me, but I SWEAR TO GOD that I speak the truth.
