Brooke: Is asked to leave the crew, returns to Laboon, there Laboon dies besides Brooke, Brooke then choose to follow by letting himself fall in the ocean.
Franky: When they reach the island that One Piece is found on, a ship starts rushing toward the island at abnormally high speed, on it is the entire crew of CP9, Franky catches the ship (much like when he tried to catch the train), the ship is destroy (causing all CP9 to fall in the ocean and drown :sad:), majority of Franky's body is shattered protecting the others.
Robin: Survives after finding One Piece, she then speaks amongst thousands of people and tells the truth of the World Government which she read from glyphs, a second after the truth is revealed - a sniper from the World Government kills her.
Chopper: Chopper hears word that Doctorine is dying, he (who is fatally wounded from the battle to gain One Piece) is with Shanks' crew (Shanks is dead), the crew return Chopper to Drum Island, there - the wounded Chopper rushes to Doctorine's side, the two slowly die next to each other - remembering the words of Hiluk… "This has truly been a wonderful life.", the both die at the same time.
Sanji: Sanji would survive finding One Piece, he would then move to Fishman Island and meet Kaimi, the two would marry and eventually age, Sanji raised his only son much like Owner Zeff raised him, Sanji eventually died of old age.
Usopp: Usopp was wounded to the point of instantaneous death, the only person keeping him alive was Chopper (who was also near death), Chopper mended Usopp's wounds while neglecting his own, once Usopp recovered and seperated tearfully from Chopper (who went to Drum Island), Usopp would return to Kaya, there he would recover the rest of his wounds - telling the stories of his adventures to Kaya, the two raised a family, Usopp would later die at old age with the same disease as his mother.
Nami: Nami released something that pained her - she had fallen in love with Luffy, already having made her map of the world - Nami fights for her life to help Luffy get One Piece, once obtained - Nami is revealed to be fatally wounded, Shanks' crew took some of the survivors (Zoro, Sanji, Usopp, Chopper, Robin), Luffy and Nami stayed behind, Luffy stayed beside Nami until she slowly died, her last words - "When you let me where your hat that one time, were you saying I was of equal worth?", Luffy responded - "You were of greater worth".
Zoro: Zoro survived, he was later found by Tashigi, Zoro knew that the military was after him, Zoro grabbed Tashigi when she wasn't attacking and kissed her, his last words - "Thank you Kuina", Tashigi (out of rage) rested a final blow on Zoro.
Luffy: Luffy outlived everyone else, he was left alone on the island of One Piece with One Piece itself, he sat there waiting, eventually the World Government captured him, he was to be executed much like his brother and Gol D Rogers, Luffy smiled and cried at the same time, "If you want One Piece, take it. But please remember the words of a dying man, you're Nakama are far more valuable".
I really hope the above doesn't happen. That was REALLY sad. :sad:
