Luffy was ready to start his journey as he was 17 today. Luffy was not like his cannon counterpart. His body has more mass than previously and his muscle were toned and his body was thin but extremely fit. He was 6'2" due to all the milk and he didn't stop drinking till now. He was enjoying his life in the truest way possible also getting stronger at the same time. he trained in his devil fruit, rokushiki, haki, naginata, martial arts for hand to hand combat. He unlocked the gear 2, 3, and 4. while his haki also reach considerabled hights, he can't use advanced form of the any of his haki. His strenth should be same or more than time skip luffy. Not only that he can produce tiny amount of lighting not enough to use it for attack but enough for to paralyze some one. He gained the complete control of the rubber powers of his fruit now he can start training in the lighting powers of his fruit. Luffy wave his hands to say goodbye to every one as he set sail on the small wooden boat.
After some time you could sea a crocodile like creature standing infront while bearing it's fangs at luffy. Luffy used haki to knock him out as he countinued on his journey. you could see a small whirlpool at the some distance away from the boat. Luffy eat all the food from the barrel and sealing himself inside. He closed his eyes and used observation haki to see everything. As barrel got sucked into whirlpool, the small boat got destroyed. Barrel was thrown out by whirlpool towards the distance merchant ship which was currently raided by pirates. Luffy was constantly watching the ship through observation haki.
Some pirates on the ship saw barrel and thought there's some alcohol in it. So they tie the hook to rope and throw it to the barrel and try to pull towards the ship. But suddenly it got of the hook and started rolling it. It went inside the ship where a pink haired boy was. Luffy can see the potential in the coby as his observation haki was different from everyone but what luffy saw in the potential wasn't mean they will be great fighter as it could be potential in fighting, swordmanship, Cooking ,Nevigating etc. Well luffy waited inside barrel for few minutes as pirates approched the inside of the ship.
As coby started rolling the barrel he heard the pirates say, " look here boys, it's our favorite little coward. you wanna drunk all the boose for yourself, huh ?" . Coby started sweating as he replied, " no, just getting some provisions is all." Coby stammered as the pirates snached the barrel from him. They lifted the barrel and stood it vertically. Pirates said , "we will take boose for ourselves". Hearing this coby said, " if alvida sama finds out,..." . coby shut his mouth from the hard glares of the pirates.
Luffy was watching all this from the observation haki as he heard the pirates knocking his knuckles he understood this was his cue to get out of the barrel. As luffy got out of the barrel he punched the pirate acting like he just woke up from the sleep. pirates got shocked and asked one-another who put him there ? while luffy just send remaining pirates flying before looking at coby and saying where's the food kid and What's your name ?
coby just stared at Luffy in awe before getting snapped out of it and answered "coby, sir and there should be plentiful food while pointing towards the door of the kitchen" . Luffy cheered at the site of food,he then jumped towards the food and started eating it. Coby stattered in fear thinking about alvida as he advised luffy to leave. Luffy just stared at coby while he was explaining about how he got on the pirate ship of the alvida as he thought how it was just an fishing ship and how he has been working as the cabin boy for whole two year. Luffy asked why not leave but he answered while statring in fear how it was impossible and luffy got irritated so he just simply punched coby.
So just luffy decided to give him courage through talk as he talked about hoe he promised someone to be pirate king and he wouldn't mind die while trying with seriousness in his eyes. coby just looked at luffy in awe as his courage grew somewhat. As both were talking alvida decided to come as she saw coby she started to intimidate him. But coby this time didn't get intimidate as he answer even in fear. Luffy saw this grinned as now he can fulfill his promise to Garp finding him a person to train in great marine. Luffy decided to end this as he punched alvida to come on top the ship as he wanted continue fighting in open. so luffy come on the top as all of the alvida pirates surronded the luffy while attacking him with Guns, swords, kick and punches. As luffy decided to end fight in one move he streched his hand backwards and then puched them forward while shouting gomu gomu no buzzuka and alvida got flying out of the ship.
As there were navy coming behinds the pirates luffy decided to run along with the coby as he searched for the small boat to the get of the ship. As he saw nami taking off her loot in the small boat luffy decided to jump in the boat while holding the coby with one hand.
As luffy jumped on the boat, it started sweaing in the sea and some of the water got into the boat, Seeing this nami was incredibly angry as she punched the two while scolding the both for what if her money got dropped in the sea.
