Could Caesar Clown defeat Ace?


Caesar ate the Gas-Gas Fruit which allows him to control gas. He can also
remove oxygen gas in a certain area. And Ace ate the Flare-Flare Fruit which
allows him to control fire. Since Fire requires oxygen to burn, then Caesar's
removal of oxygen from the air could have defeated Ace's fire power.

So we conclude that Caesar could have easily defeated Ace?




If you are thinking of a mere rock-paper-scissor, it would indeed look like
Caesar fruit has an advantage, similar to how Luffy "Gum" fruit had an
advantage against Eneru "Lighting" or how Akainu claimed that his "Magma"
power was stronger than Ace "Fire".  
On the other hand it is not like a "weaker" fruit hasn't beat a "stronger" one
before, even with some elemental advantage involved. Also, it is not clear how
far Caesar powers could reach. He doesn't seem the type to have trained that
much and instead seems to rely on the base advantage of a Logia. I also doubt
he has any decent level of Haki, while technically Ace was shown at least once
to use the Conqueror variant (that said, it appears only in the flashback and
never again).

But let's keep it simple - **can Caesar douse Ace flames?**

The real issue is that we are talking about speculations. It has never been
specified **how** Logia fruits create things out of nowhere. Do they consume
stamina/willpower/ki/mana? How can someone conjure a giant fist made of magma
up in the sky? Where did that molten rock come from?

It is a common misconception that fire requires oxygen.

This brings quite a bit of questions...

  * do Ace flames require any combustion in the first place? You seem quite sure they need oxygen as the oxidizing agent, but then please tell me also what is the fuel that gets combusted.
  * if they require combustion, do they use oxygen? If the Logia can create the "fuel" then it should be able to create the oxidizing agent too?
  * if Ace powers are a form of combustion that can use any oxidizing agent, can Caesar remove oxygen at atomic level too so that there are no oxygen atoms left? Just to point out the absurdity, this means that Caesar should be able to turn water into hydrogen?  
etc etc etc.

Seems we won't get anywhere this way, so let's try to compare Ace with someone
similar instead.

The Human Torch maybe? This scene from a comic is quite similar to what you
seem to expect: a foe removes oxygen from the area and the Human Torch flames
are affected.

[![The Human Torch claims that his flames will die out without oxygen after a
foe used that trick against
him](https://i.stack.imgur.com/cLmD4.jpg)](https://i.stack.imgur.com/cLmD4.jpg)

But in another panel form a different comic he can fly thru space despite the
lack of air...

oxygen](https://i.stack.imgur.com/3JoX9.png)](https://i.stack.imgur.com/3JoX9.png)

... or at least he can until he can not in yet another issue.

[![but he then remembers there is no oxygen
there](https://i.stack.imgur.com/oUujr.png)](https://i.stack.imgur.com/oUujr.png)

... and don't get me even started on "Power Cosmic" Human Torch.

Let's look elsewhere. In Fire Force the (basic) Infernals seems to be subject
to dousing like any flame would - Akitaru Ōbi even uses dousing grenades. At
the same time there are scenes where the acutal Adolla flame is shown to be
demonic in the real meaning of the term and it does not seem to douse in any
way.  
In Ben10 Heatblast can't breath in space and is weak to water, oxygen
deprivation and anything you would expect to douse a flame.  
Then you have Jaganshi Hiei from YuYu Hakusho dark flame, which isn't
conventional by any mean and is probably more of a demonic flame too.

and so on, I think you get the point: every show has its set of rules, even
when we are talking of the same base trope...

At the end of the day only Oda could decide how the fight would go. You
imagine Caesar dousing Ace fire, but Oda could as well decide to go for a not-
even-worth-my-time scenario with "Caesar explodes as soon as he tries to turn
to gas because gas+fire=boom". Considering that the Ace is dead and many
expect Sabo to face Akainu for revenge at some point, I would not be surprised
by a "I'll mop the floor with you" battle with the Flame Flame fruit revealed
to be not physical fire but the very idea of burning and awake to spontaneous
combustion of anything near, including Akainu's magma. After all, it is not
like other fruits weren't presented for what they actually were in the first
place... so maybe suddenly the Mera Mera will actually be Hito Hito No Mi,
Model: Kitsune.

That said, again, this is just speculation and unless Caesar does try this
against Sabo now we will probably never know if that would have worked unless
someone asks Oda directly in the SBS corner.
