Explanations
First off luffy's hybrid fruit
Luffy still has his gum gum power since its kinda hard for me to imagine luffy without it it just fits him so well.
Now his Logia power the Mizu Mizu power. This power helps luffy be able to swim since as he enters water the water around him instantly repels all salt in the water space he is in imagine a really good water purifying machine and that is Luffy. As for why he was getting his ass beat without turning to water is because Luffy thought he only had rubber powers and was thinking of how he cant get hurt because of his rubber powers which is why his mizu mizu powers did not work he wanted to use rubber and so thats what happened.
Now that he is aware of it his body will react like any other logia attacks go through him, unless he doesn't want them to or its Nami since she is on some God Level shit.
Second: Ace Sabo Dadan. The entire reason i have that 3 year gap is so luffy can meet them before he sets off. Sabo will be gone with revolutionaries since bluejam, and Ace will stay at Dawn Island till he is 17 like the show. And Luffy will remain a little bit weaker than Ace since he will learn about some basic to mediocre medicine, DECENT Navigation, swordsmanship, Gunmanship and he won't be a complete idiot but will still retain his Luffyness if you get what i mean. He will be mature but act childish kind of like me if i think about it.
Luffy won't set off with Shanks till chapter 3 or 4 and he wont start his journey till 5 or 6. But don't worry that will happen soon its the holidays after all.
Also some characters backstories will be altered a bit one is going to be Nami you will find out how very soon. Hehe
