Who Is The Mysterious Prisoner In Wano’s Jail?

In the Udon region, people are put hard to work making weapons in Kaido’s factories. In the dungeons of these factories, one of the Beasts Pirates delivers a poisonous fish to a certain cell. Their orders are to give a poisonous and boneless fish to feed the prisoner inside, who seems to be still alive in spite of the poison.

The Beasts Pirate guards then rejoice as Luffy is brought in, and they taunt him. However, the mysterious prisoner spits out the fish skeleton at the guard and strikes him in the neck, causing him to be reprimanded for not taking the bones out of the fish as ordered. Who is he? Is he a new character? The lurking legend? Or a character that we already know? I think he might be the former Roger Pirate Scopper Gaban. I mean the first time we saw Rayleigh he was in a prison too and all the Supernovas were in attendance.

This time 8 Supernovas are present in Wano as well. I was thinking that the mysterious prisoner is so strong that he has been surviving on 1 poison fish per day for don’t know how long… so who’s this person that even Kaido wanna kill? I mean Kaido’s policy is if you are strong then i break your will and you work for me so maybe this person is mentally and physically so strong that he just can’t be broken like that so maybe he is Scopper Gaban. Kid, Luffy and Gaban might escape outta this prison together and then Gaban could train them about Armament/Conqueror’s Haki or Awakening so their chances of defeating Kaido would increase.
