My friend and I were discussing what the strawhat lives could be like after the events of One Piece and he said that Usopp will end up like Krieg.
This is because
A] Usopp and Krieg have similar fighting styles (as in they both have suprise attacks)
B] Usopp always speaks of having 3000 men or so, didn't Krieg have around that number?
C] You can knock them both around and they won't die.
Although true, I very much doubt that Usopp will become as evil as Krieg, and will most likely run away, but hey, I thought it to be a pretty good view into what Usopp might be like in the future
