Geno Whirl

Geno Whirl is the meanest attack in Super Mario RPG: Legend of the Seven Stars. If it isn't timed right, it will do just around 500 or 100 damage. But, if timed right, it will do maximum 9999 damage. No lie. That's true. It doesn't apply to bosses and stronger enemies (mini-bosses), though. Well, it applies to Exor. That's a Time Level 1 attack.

Timing
The timing is a bit frustrating. You must hit any letter button EXACTLY when the last circle goes out of the screen. If it's timed right, a thunder sound effect will play. Why is that hard? Well, every circle gets more and more transparent. That means, that the first circle is seen in complete colour, the second with like 90% transparency etc.

Exor
When you stun the right eye, or both eyes, you can use that on the top part of the sword (the part with the flashing thing). Why is that like that? Isn't Exor a boss? If we want to be honest, not. He's used for a portal to the Factory. Only the eyes and the mouth are a boss. The main part is a normal enemy, that can be attacked only if the right eye boss, or both eye bosses are killed.
