Yea he would have died right away. Falling off that cliff would have killed him. Being that he is rubber comes in handy.
Lovin that face
And not as strong :|
Kinda hard to say, he would still have BH, but he would have needed to survive that long.
Without his fruit he would have died on Skypiea (if he had got even there)
Yes but then so many things would have been diffrent even before that,actually the entire story would need a change
This is a very broad question and isnt as simple to answer as if you asked what if Naruto didnt have Kurama cause his life would be normal and he could learn evreything from Minato/Jiraiya/Kakashi but for Luffy its diffrent.He would have to develop his skills diffrently with Ace and Sabo,maybe he would get more out of the training with Garp,would need to learn haki sooner etc...
Even Crocodile would kill him without gomu gomu no mi since it gave Luffy the ability to store water and do the long reach attacks etc..
Basicly for Luffy its a whole new story
I think I pretty much said that, just took up less lines :|
its gotta be a wally U_U
