Again, I said plasma like. It isn't normal plasma. It just has its physical properties. And as for the weight of Razors Dodgeball, all that goes to show is that he is surrounding it in an extremely dense field of aura, therefore my theory about small numbers of high energy particles was wrong and my old theory was right after all. You said that Gon wouldn't be able to hold up his fist is aura had mass, but the fact that he does goes against that. Razors dodgeball was as heavy as a bowling ball, and granted while a dodgeball has a much larger surface area than a fist, Killua was still able to hold it up without much of a problem. Therefore, Gon who would have produced much less aura would undoubtedly be able to hold up his fist while using Jajanken. How do I know this? Because he holds up his fist while using Jajanken! These characters are much stronger than you lead them on to be, even without the added power of Nen, so its more than plausible(to the point of being likely) that they are able to tolerate the mass of their aura.
