@Yoska:
Yeah… but didn't say anything about something getting too big.
The thing I'm saying is: he just created a chain reaction.
I´m not doubting that he created a chain reaction. But the chain reaction is that what is too big for him to handle. One of the pieces of it is something he has control of and thats the sand that he manipulated to become a sandstorm.
If it wasn´t for his power then actually I could also create a sandstorm if I throw some sand in the wind and wait until it gets big. But it doesn´w work like that. His logia powers made him create it. But since he only controls sand and not wind too, he is not able to handle the complete thing. But without his control over sand a sandstrom wouldn´t have been created. And last time I´ve checked were discussing whether or not he is able to control the element sand and not the an elemental power combined of two different elemenst, wind and sand.
So I still say, that Crocodile can control sand. His whole first fight with Luffy at the gates of Rain Base prove that actually. He used the sand there for his attacks. It´s not like "Desert Girasole" is a move that he could pull on any place else besides a desert.
Ace made fire but that fire was from him. The control of the element would mean Ace could fire up or extinguish a candle with just by looking at it, not by shooting at it.
What tells you that he couldn´t do it? In his side adventure he saved some marine from the flames. True he didn´t put the fire out, but he must have somehow protected that poor soul from burning. Otherwise anyone else could have also jumped on board the burning ship.
And don´t say he jumped because he´s invulenrable to fire. That may be true but if he is invulnerable then it doesn´t mean that the guy he saved is so somehow his power was also helpful to protect someone else besides himself.
I kick water and a wave is born. This doesn't mean I can control waves.
But this analogy doesn´t apply on our example as much as Kintaro´s "I light a fire" analogy doesn´t apply. Where talking about elemental users and controling the element. So unless you are not an wave logia user or Kintaro isn´t a fire logia users your analogies don´t work because Crocodile is a sand logia user and we are discussing his powers of controling sand.
