[Predictions] The voice Luffy heard

[KakarotxUchiha]

Is probably zou cause he can hear the voice of all things like Gol.D

 

[LBeezy]

This is what I'm hoping for as well!

 

[loj]

I thought of that as well since there was some talk about it in Fishman Arc :x3:

 

[Angelic.]

Zunisha. Its like get these a holes away from my legs lol

 

[MickNerks]

It is Zou
Just like the Sea Kings

 

[Uzumaki Macho]

Luffy can hear the Voice of All Things, so he can hear Zunisha just like he heard the sea kings.

 

[Rikudou Tobi]

He hears the cry of the living island so he'll go solo Jack.

 

[Naruto Power]

I agree voice of all things. I see luffy jumping down with giant Gatling gun move just destroying most ships. then later zou talking to luffy about the voice off all things. who better to get info from new power coming maybe.

 

[YellowFang]

Yep, he's hearing Elephant's voice...

 

[SESH]

Is probably zou cause he can hear the voice of all things like Gol.D

was it also when he was up in that tree in the sky island arc with the group of monkeys

 

[Strict]

I would guess it's the Road Poneglyph. First of all, it seems as this voice took Luffy's attention from the crying Zunisha and secondly, the wale was displayed.
