In conclusion, the personalities of the three characters have been swapped.
Basically, the two people switch places in the morning and night, and only during the full moon.
Another special personality appears.
Blackbeard’s appearances are always in the morning.
Full Moon’s Blackbeard has not been drawn yet.
Night Blackbeard only appears once at Impel Down level 6.
Only in the scene where Blackbeard goes to a dark place does he have all his teeth.
When I read it in Shonen Jump, I thought it was a mistake.
Even in the comics, the correction was not included, so Oda-sensei deliberately
It is thought that this is the only frame in which Blackbeard has all his teeth.
