Uh no. Smoke is more than gas. A common definition of smoke is=
"Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion or pyrolysis". It has solid particles (and some liquid according to some sources) in it as well, and gas is a different state than solid. Caeser is gas logia, and only gas
The only overlap with Magellen is both can create poisonous gas. I don't see it as a problem, as one is paramecia that secretes any poison and other is logia that transforms into gas.I had thought that snow and ice as the same, just a difference in hardness. But a search online showed me difference. This is the repeated answer I got to "what is the difference between snow and ice?"=
"Snow is nothing but the frozen atmospheric vapour which falls in winters on earth as light flakes whereas ice is simply frozen water."
{but to complicate things Wikipedia says=Snow is a form of precipitation in the form of crystalline water ice, consisting of snowflakes that fall from clouds. Since snow is composed of small ice particles, it is a granular material.
since we are talking about logias, I'm going to use the first one to differeate them}Read more: [http://wiki.answers.com/Q/What_is_the_difference_between_snow_and_ice#ixzz2A 0GHtTvj](http://wiki.answers.com/Q/What_is_the_difference_between_snow_and_ice#ixzz2A 0GHtTvj)
Ah I just showed above they are not the same so I don't think that CC can control smoke or Aokiji can control snow.
As I said above, I just found out that snow (frozen vapor) is different than ice (frozen water), so nope Kuzan can't make it snow. But by the same token, in the real world magma doesn't create the flames. Magma is just molten rock. Its the intese heat that causes things to dry out and combust, so the flames are a byproduct of the magma. Just as ice can make it so cold that snow can form
But remember it's been two years from that battle. So pently of time for the extreme heat/cold to create the scene.
Yeah i looked at wikipedia too but even so smoke contains gas and depending on what the source is usually in large amounts and a various types so Caesar should still be able to manipulate it. And while we classify snow as different from ice because of things like weather, snow is still frozen water, just in a different form. So when you get down to the basics of what these DFs are they still have higher tiers. We've even Seen Aokiji use his DF to travel partially as frozen ice particles and they often surround him when he transforms so saying that he has no control over them doesn't make sense.
It could just be the way it was was chosen to be animated but you can see that he often creates small ice particles around him or forms larger attacks from them so it would make sense that he would be able to manipulate snow especially if monet made something like a snow hut. But you can also see that Monet would never be able to do most of the things he can do simply because of the limitations she's shown so far with her fruit.
It's possible we'll just have to wait and see if they comment on Monet's ability like Kid said or if Smoker and Caesar meet.
