Lets talk about that.
Recently it was finally explained whats up with Natsu and his whole age thing
You think Mashima will ever get back around to explain whats up with Gazelle (I know its not the canon translation). Or is he stuck in tertiary character hell.
Why do all of you think he registers as and octogenarian?
I thought it was implied that the reason that Gajeel and Natsu couldn't go through the barrier back then was because they had their dragon parents inside them(I guess it could count as both for Natsu though)
It's weird, because Natsu & Gajeel's ages are not known (well Natsu is somewhat 400+ years old... kinda). But yeah as the person above said, same I thought it was because of the dragons. Also in chapter 436, when we see Natsu in that egg-thingy, there are others egg-things that seemed finished. So perhaps Gajeel is also one of those? Or does could be failed experiments who knows xD
What I wonder about Natsu is, what happens when he dies?
Does he just get reborn just like the other Demons because Zeref has his book, it could be why he's age has reset.
As for the other dragon slayers, what if their Dragons took them through that timegate, Gajeel and the other slayers could be humans from the past brought to the future in order to keep them safe.
I honestly don't believe Gajeel and Wendy could be Demons to because that would take away from Natsu significant story plot and the story as to why Dragons choose to teach Humans Dragonslaying magic.
I think all the dragon slayers taught by a dragon natsu included were sent forward in time my guess is Layla might of had something to do with it. This is the best explanation for Natsu since he was confirmed 400 years. The dragons inside theory was fun, but I don't think it's valid anymore it feels like a red herring as well as the other dragon slayers ages.
Hmm maybe you're right, I looked back at the chapter and the rules for the barrier were "No statues or people over 80 may leave" so unless a dragon is considered a person then they shouldn't have been affected by the barrier. So maybe Gajeel and the other "real" dragon slayers are like Nastu(some how preserved for 400 years before awakening).
