Kuma sent PX-1 off to somewhere unknown, presumably to keep it from destroying or capturing the Straw Hat crew.
What if there was an ulterior motive?
I think it’s possible he sent it to the Revolutionary Army for study and possibly so they can attempt to rewire it to work for them. I thought of this because of Oda’s love of the Terminator movies (displayed by Kuma’s design). Having a “good” Pacifista would be a great homage to T2 and give the Revolutionaries a great weapon.
What do you guys think?
