Sorry this took me a bit to get to, work has been doing that thing where I’m only able to be creative when it’s kinda slow. But the fact that you’re still asking me about the crossover….
You’ll let me love you forever right?
Ahem! Anyhow…! So! Here’s a few headcanons for you – I’ll probably elaborate a bit more on these in the actual story.. [Hiya @phoenix-manga tagging youuuuu cause crossover! Woo!]
But, the Hunter does have an array of weapons by the time the get somewhat settled with the boys on Eos. Mind you, Cid was right confused when the Hunter asked him to build a greatsword made of bone, but he figured things out alright in the end.
Noctis was nice enough to let the Hunter store their gear in The Armiger, and of course, one day, Noct was curious about the weapons they were using, so the bros asked to use them one day at training.
So..there was a lot of trial and error in the beginning..
Noctis: had been eyeing that longsword ever since Cid built it for them, and he was positive that he could use it easily enough. However the first time he picked up the blade he didn’t think he’d flop over face first at its weight.
He got really good with the Spirit Thrust attack with the weapon though, and adding his warp ability to it as well, he almost got harder to hit than the Hunter when using it.
Prompto: He became almost a pro with the Gunlance. When he could compensate for the weight. “Jeez, how do you move with this thing?!” and he came to realize that it was much like the Machine weapons he’d used from Niflheim.
The Hunter got a bit jealous with him using this weapon however, because he could get the Wyvern’s fire to go off more often than they could.
Ignis: Being ever so elegant with spears and daggers, he figured he’d do well with the Lance or with the Dual Blades, and despite their size, which he compensated for rather quickly, was actually able to master them in a short time.
The Hunter started to affectionately call him Demon, just because of how often he’d flip into the ‘Demon mode’ with the blades and would become more acrobatic if that was possible.
Gladio: The Greatsword was his choice, just because of the fact that the first time he’d seen the Hunter use this weapon, he was impressed by its size, and the fact that it was so damned heavy and they could lift it with ease, he was impressed with it to say the least. And since he already used a greatsword of his own, all he had to do was compensate for the weight.
He loves tackling monsters with it. And the Hunter swears that they made a mistake teaching him how to do that.
