The fan blog actually went over this in detail. Fire is a good conductor of electricity due to the plasma it produces. As this is the case, and one of the primary weaknesses of Logias is that you can utilize its physical properties to bypass the intangibility, it actually does make sense that Natsu's lightning attacks should be able to hurt Ace through his Logia Intangibility, utilizing the conductive properties of fire to hurt Ace's true body within the flames. In essence, it's a bit of the same concept as the way Luffy beat Crocodile. Luffy solidified Crocodile by dousing him, causing his sand body to stick together. In this same vein, Natsu utilized the conductive properties of flame to bypass Ace's intangibility, with the electricity harming Ace regardless of his flame form.
Ok. This clears some stuff up I asked you in your other reply, but doesnt prove how conducting electricity gets past Ace's intangibility. Croc was specifically weak to liquids.
People often say that Ace's true body is not his flames but that his body is flames. If this is the case, then while it means that while MOST of Natsu's attacks should not be able to hit Ace within his intangbility, since Ace is technically flames while in his intangible form, the electricity SHOULD be able to reach him assuming he touches a portion of the element that is connected to where Ace's true body should be. At the very least, while being in his intangible form WILL stop the fire portion of the attack from harming him, there is still the electricity to be worried about.
Ok I finally had time to go through it and basically it relies on a ton of scientific ideas and theories that are heavily debatable. Also, their "expert" on logias had no fucking clue what he was talking about on Croc or Enel.
That's a NASA FAQ (may be dated) where they answer the question of "Is fire a plasma?" by saying no as the flame in their experiment did not conduct any electricity.
Then you get into the weird debate of fire being a plasma or not and whether or not fire conducts electricity too. To both, the answer basically boils down to maybe (????). Also, any combination of yes and no (except being a plasma and not conducting electricity as not conducting electricity would mean it isn't a plasma) is possible.
If fire is thought of as plasma, then it would conduct electricity. However, under the same line of thought of having fire be plasma, you'd also have to believe lightning as plasma too, making Natsu's lightning form going past Ace's intangibility the same as saying fire could do so.
Now if you go with fire conducting electricity, but not being plasma, you're forced to recognize not all fire conducts electricity, meaning you can't prove Natsu's lightning form will hurt Ace due to selective conditions you'd have to enforce on Ace's fire. The "proof" of fire conducting electricity is reliant on specific conditions, usually the fire being dopped like propane.
Finally, nothing they've posted proved lightning would hurt Ace through his intangibility. Basically, they make a fuck ton of assumptions here.
