We all know that in the past Bartholomew Kuma was friend with Emporio Ivankov and Dragon, but marines erased his memory.Is there a possibility that kuma will get back his memory in right time ?
That depends if he's still a cyborg or a 100% robot.
I think he will still have his brain left untouched and as long as it's there he should be able to get back to his true self. If he's a complete robot there's no chance he could return.
I think there is a secret code that Kuma will remember again that he was a revolutionary, which only Vegapunk and the higher members of the world government know it. Maybe even Dragon.
I had a theory that his Bible is there for him to remember glimpses of his past.
Idk though... Maybe Vegapunk still has his personality stored somewhere
