Why couldn't he simply turn into fire and repair the damage?


Spoiler alert, stop reading if you're not past _One Piece episode_ 483.

When the guy (Akainu) put a hole in Ace, why couldn't Ace just turn into his
element like all of those elemental Devil Fruit users? I get that magma was
able to burn him, but how does that stop him from just dispersing like the
other elemental fruit users?




You can read [here](http://onepiece.wikia.com/wiki/Logia) that:
