《海贼王》 Theory on why Kuma has done what he's done
A thought came to my mind lately. So before the timeskip and before Kuma became a complete cyborg Ivankov was imprisoned right. So what if Kuma made a deal with the marines to become a part of Vegapunk's experiments in exchange for Ivankov's life, as a means to ensure he lived long enough for dragon to bust him out of impel down. I mean not even Kuma could have known that Ivankov was safe in level 5.5 of impel down right?
What are your thoughts on the matter? Do you think its plausible or maybe you have another theory?
