If he's not a complete sadist, especially as the month break happens at the end of this month, we will see his face hopefully! No reason we shouldn't at this point! Oda didn't do this to other Admirals either, they just appeared suddenly.
I think he's hiding Green Bull's face purposely because he is Ushimaru's son or related to him and Zoro's father. Why hide his face otherwise? His face is gonna be familiar to use somehow, its gonna be important somehow.
Oda is purposely going out of his way to hide what Green Bull looks like, why avoid showing his face as he talks hear and appears properly without being a silhouette?
It's way too damn suspicious.
But I got ridiculed for trying to provide a lot of "evidence" earlier on why he is related to Ushimaru and tried to be as reasonable and open minded about it too but you know, people don't want to read, give it a chance and listen.
We really need to see what he looks like, enough games already Oda. We went SO LONG waiting for Oden to be revealed and especially the prisoner in Udon who just turned out to be Kawa-mid-su. All that hype/teasing/baiting/trolling by Oda for so long, just to get that, sigh.
I can't believe we're gonna end up seeing what he looks like fully even before Vegapunk has a full proper silhouette at least!
