Luffy being the enthusiastic adventurous person he is shouted, "LET'S GOOO!"
Mew-Wailord started moving, picking up speed as he moves sometimes creating small waves. 'This is amazing, who would've thought I would reincarnate into the world of One Piece let alone become a broken pokemon.' He thought surprised but at the same time excitedly.
On the deck of the Going Merry Luffy was so excited his pupils partially turned into stars, "SUGOI!!" he shouted. He rushed off the ship landing on Mew-Wailord's body before sitting in a lotus position, he touched Mew-Wailord's body his fingers partially sank in due to its softness.
(A/N: apologies, if the Sugoi sounded cringe, but saying amazing, wow, awesome, etc. alone doesn't fit Luffy's character as well as saying Sugoi, in my opinion. I'm going to add what Mew transformed into after his name from now on, for example, Mew-Wailord, Mew-Luffy. It not only helps me keep track but also helps the readers, a little.)
"Chopper! Usopp check this out! It's so soft!" called out Luffy with the same excitement turning towards the ship, to only see a terrified Nami, Chopper, and Usopp. "L...look behind you Luffy!" said Usopp, his voice trembling with fear.
Luffy followed the other's gaze, and behind him stood a snake-like sea king with two large fangs and a lion mane speeding towards Mew-Wailord with an angry glare, the sea king was enraged that another 'sea king' dared to enter its territory.
Once Luffy saw the sea king immediately stood up and took his basic gomu gomu no pistol stance, ready to hunt this new source of food. Sanji and Zoro also leaped over to where Luffy stood taking their own stances.
Suddenly Mew-Wailord spoke interrupting the trio who were ready to hunt this new foe, "Wailord wailord wailord!" getting outta his terrified state Chopper translated, "Mew said, 'hold on tight everyone, I'll take care of this,'" before grabbing on the white wooden rails of the Going Merry tightly, Vivi, Karoo, Usopp, and Nami also copied his actions.
(A/N: Karoo is Nefertari Vivi's pet super spot-billed duck, a fleet riding bird one of the fastest modes of transportation available in Arabasta.)
Mew-Wailord opened his gigantic mouth sucking in a lot of sea water, creating a tiny whirlpool. This sudden action had the trio on his body wobbling from side to side because they had nothing to hold on to and didn't hear Chopper's translation.
A sphere of water started forming in the middle of Mew-Wailord's mouth, the sphere was violently shaking as if it carried a lot of power. The sphere expanded at an extremely fast speed from its initial basketball size to about half the size of the MSG London Sphere.
Mew-Wailord closed his mouth with the water sphere still expanding inside before firing it like a bijuudama towards the snake-like sea king. The water beam moved at an extremely fast pace and immediately obliterated the top half of the snake sea king. Its body slowly fell into the sea, floating motionless.
(A/N: the move was Hydro Pump.)
"What?!" exclaimed Luffy stupified about what just occurred, everything happen too quickly to even make any sense of it. 'That...that was powerful, I don't even think I will be able to block nor resist it.' thought Zoro while looking at the dead body of the sea king.
Suddenly a huge explosion occurred a hundred or so feet away from Mew-Wailord's initial position, of course, this was the aftermath of the water beam, being fired at 100% power since Mew-Wailord doesn't know who to control all of his abilities.
'I didn't think it would be this powerful, I should never try using moves like this casually,' thought Mew-Wailord with sweat dripping from his 'forehead.'
"SUGOI!" exclaimed Luffy over the moon with enthusiasm, he stretched out his arms and easily picked up the sea king and brought it up on top of Mew-Wailord's body.
The others who saw the evisceration of the sea king were left speechless, "Mew-san is..is amazing," muttered Vivi under her breath, the rest could only nod.
Luffy ignored what Mew had just done and turned toward Sanji and asked drooling, "Can you make food now!" Sanji could only sigh, "fine bring that thing to the ship," he said.
---<^>-----
An hour or so passed since the battle and Mew-Wailord was only 100 meters away from Alabasta island, so to remind his crewmates he roared, "WAILORD, WAILORD!"
(A/N: 1 meter is 3ish feet so 100 meters is around 328ish feet.)
Chopper who heard the roar got excited and immediately translated to the crew who were all around the dining table eating food, "everyone mew said 'we're close to the island and will reach the it in few minutes.'" Hearing this Vivi stopped eating and rushed outside, followed by the rest.
Once they were outside they saw a sandy island and a city in the distance. They could see the city because of Mew-Wailord's height. 'I'm finally home, wait for me dad, I'm almost home.' thought Vivi looking towards the city with longing.
