2Y Usopp Predictions:

He will be brave, he will be courageous, He will be the greatest warrior of the sea, and he shall claim his right to captaincy!!

He will also spin the greatest lies of them all!!!

-I feel Usopp is going to arrive in some of the craziest armor we have ever seen.
-He will tell us stories of how he nearly escaped death (and lost all the weight while doing it)
-He most likely will blubber a little when he sees everyone together (or at least Luffy), breaking his awesome aura and reverting back to the good ol' Usopp.

- I think he'll ditch his bandana, and do something different with his hair
-He will most likely have a new weapon (not pictured here <.< ) Or at least his Kabuto will be highly upgraded.
-He may bear gifts to everyone, new weapons and such (like to Nami)
-I think, he'll lose the weight, and become more fit, not as fit as Zoro or Luffy, but more so than Sanji.

Either way, I feel Usopp is going to be one of the funnest to be reveled!!

Sanji is Tomorrow
