Maybe the VA has to stay sober to do the new voice but yes he did sounded like a generic hero on a journey. I dont think its going to last though. Ussop will finally show his true colors. Maybe he has finally become a man of the sea. If he is going to join Luffys crew again then he will have to do some heroic stuff to be accepted back in the gang. How far he has planned on this act is unknown and will certainly bring joy to us.

Hail new King.
