I'm arguing the only point I've been arguing. That there's no proof that Teach is the only one able to ever eat 2 DF's and just because the majority of the OP population believes it to be true doesn't make it so. Teach is the only one to do so, so far but that also isn't any kind of proof that no one else will be able to also.
You were arguing that Marco did not refer to a single devil fruit user as normal and BB a double devil fruit user as not being normal, and you argued that teech isn't the only one who can use two devils fruit.
Which is 100% wrong.
What? Because 2 people have had the mera mera this makes that any one who eats a second DF will explode and die a law? In what world? All that implies is that the OP population believes it to be true, just because it's the popular opinion doesn't make it a fact. Those 2 DF users not eating the Mera Mera doesn't prove that nobody besides Teach is able to eat a 2nd DF it means nobody besides Teach is willing to risk it because of the information the WG put out. But here's a fun thought, maybe the WG purposefully put out misinformation to reduce chances of threats by preventing any one person from amassing too much power. I know a bit of a reach, not like the WG wouldn't put out misinformation. Now I don't think just anybody is able to eat more than 1 DF but I don't believe Teach is the only one able either.
Because Doffy or Diamante not eating Ace's fruit would not be beneficial for to beat Luffy and become stronger? Common sense, they could not eat it. And how about Oda's law, that anyone else who eats it explodes and die period. That's a manga fact.
Unlike most people, Teech knew he could use more than one devil fruit so he didn't risk anything.
And are you questioning the scientist now? So you're saying three pages of the manga is wrong just to support your stupid theory?
Psst. You don't know that since we have no information on their anatomy. They're not normal within the context of the story or the OP world no matter how you want to try and deflect. Notice the only known 2 fruit user is a D also.
Psst. This is the most retarded thing I've read. You're arguing with me that Luffy is not human? You're literally arguing with me that luffy and ALL the other D. are extraterrestrial? You are seriously reaching hard.
Obviously it isn't always imminent which is my point. If one character was capable of it then that opens the door for other possibilities. And just because a character says it within the context of the story doesn't make it a fact, it just means that that character believes it to be so but characters can be wrong. Blueno said the Grand Line scientist studied the phenomenon but yet nobody seemed to know that the YYnM could acquire a second fruit until Teach got a hold of it so how complete is their information?
Do you know what imminent means? When you explode, you die. That's as forthcoming as it gets.
And Blackbeard himself said that he studied the yami fruit which is why he knew he could absorb devil fruits. Just because the government didn't specify doesn't mean the broad topic of taking in two devil fruits will not result in death.
Nobody can use BB's unorthodox method of gaining more than one devil fruit, because he didn't ingested it just so you know.
Neither of them did anything remotely close to tore his body apart. Gear 2 had drawbacks to his life span but that's got absolutely nothing to do with his body expanding and withholding an explosion. Gear 3 made him small but doesn't anymore but showed he can expand to large proportions. This did nothing to disprove Luffy can expand to considerable sizes and could in theory withstand an explosion that would result from eating a second DF.

You're theory has nothing.
Not when that's what his fruit is supposed to do. Do you really not know what the Phoenix represents? Or do you just not think Marco has the powers of a Phoenix with his Mythical Zoan fruit?
I know that Marco does not have the power to resurrect from the dead and I know that marco's fruit powers as kizaru said has blue flames that regenerate.

So it's clear to me that you have no idea on what you are talking about.
And yet the very page you use as evidence Marco says he thinks it's Teach's body that allows him to have 2 DF's. Regardless Teach's DF allowing him to have 2 DF's just shows that there is a chance that there's more than 1 fruit that can do the same, all the fruits aren't known and they're not all well known to the general public so people not knowing another fruit would allow you to do this means nothing because nobody probably knew the YYnM could do it either until Teach came along but the fruit existed before Teach so that means the ability has been around but people were unaware how to use it this could still be true for other fruits like a mythical zoan based on regeneration or the MC's DF.
There is no chance, just you and your speculation. And like Teech told Ace, he did some research and knew that ONLY the yami fruit gave him these properties. It's also the only reason why he killed joined WB ship and killed Thatch in the first place. You know, just in case you didn't read that part.
If you eat a DF you get the powers. If you have a DF already and eat another one you explode but you'd still get the powers before your body exploded because that's how DF's work, the power is in you after the first bite. So if you are able to survive that explosion you would have 2 DF abilities. Teach survived the explosion by using the YYnM to absorb the explosion I think, Luffy would use the GGnM to expand beyond the explosion size and Marco would need to eat it in Phoenix mode because his fruit repairs all damage based on the name until shown otherwise, that's why they had to cuff him at MF and after his cuffs came off all his wounds from when he was cuffed were healed.
No you don't and no where in the manga did it said it worked that way. Keep your fanfic theories out of Oda's mouth. As for "surviving" the explosion, Teech did no such thing since the explosion never happened.
And Teech didn't eat the 2nd devil fruit just so you know. The rest are just more senseless theories.
No I'm taking his words at face value for exactly how he says them, you're putting implications on them and saying what Marco was really talking about to fit your stance. Marco literally says "normal people can only have 1 DF but Teach isn't normal...maybe it's his body" This bit about Marco lumping himself in with normal people is subtext you're reading but that doesn't mean it's there. Plus if he meant to include himself why didn't he reply something like "Normally we can't but Teach is different"?
Marco made a suggestion that it might be his body but the context is exactly as that. You cannot have a second devil fruit without already acquiring another. He said normal people can only have one but normal people cannot have another. It's as simple as that unless you really wanna keep playing dumb.
That's literally what his fruit is based on, The Phoenix, the fruit itself implies that while his fruit is active he can not be harmed or killed. Whether that holds true or not is something to be determined but based on his fruits inspiration, signs are in his favor.
Hahaha

Where in the manga was that fanfic stated?
Was it

Now he's so immortal that he cannot die? Fascinating.
