Maybe the Samurox thing works like the Alpha in HTTYD. The baby dragons are immune because they listen to no one.
Possibly…but those babies were, like, the dragon equivalent of toddlers I would imagine; given their “baby fat” appearance and…(checks) okay, so I think they have teeth? But they’re hard to notice so they’re not fully emerged, I suppose.
Regardless, who knows…as far as I’m aware, I think Beau was the only dragon whose age was explicitly mentioned—that being 16. All other dragons haven’t been confirmed (again, as far as I know). But then, we don’t even know for sure how dragon lifespans work; like, if they’re the same as humans’ or not. Connor saying “you’re sixteen now, just like Beau” makes it seem that way, but him breeding dragons to breed a new gold dragon makes this seem improbable.
Hmmm…regardless, it is more than likely that Frachsun was too young. Perhaps you’re right and he’s too rebellious in his child-esque age. Frachsun probably only gets along with Lance so well because they’re either the same age or really close. X3
