I don't own Pokemon or the idea of this story which I got from Captain Buggles. I just own my OCs.
TMs will exist in this universe but instead of replacing older moves I will just add to the list like TM02 is still Razor Wind while Headbutt is TM57. I will put a list of TMs in this universe on my profile and I'll just make the HMs TMs as well.
If you have a problem with me capitalizing words like Pokemon or Charizard deal with it because I always capitalize Pokemon and their names same with a good portion of extinct animals like Amphicoecelias and Uintatherium.
Meanwhile Max and May split up from Brock and Lizabeth. Eventually Max and May cross paths with Ashley,only to find that the Captain's right hand man was right behind them with a Beedrill. The Beedrill attacks with Pin Missile, Pikachu countering with Thunderbolt. Then the three try to escape, but Beedrill uses Sludge Bomb to block their path. Ashley decides to stay behind to take care of the Beedrill, while May and Max run off with the Egg. Meanwhile, Captain Phantom manages to catch up with Jackie, only to have Jackie reveal that what he was carrying was a pair of juggling balls. He throws one at Phantom, in which he smacks it towards a nearby cliff wall. The ball simply bounces back and smacks Phantom in his face. Taking advantage of the odd but fortunate turn of things, Jackie runs off, jumping on a boulder. But somehow Phantom begins picking it up, and tosses it. Jackie jumps off however, but the Captain isn't interested in him anymore and begins searching for the Egg.
Max and May find themselves at split in their path, hoping that everyone is okay. Suddenly the Captain appears from behind and tries to pry the Egg container from May's hands. As May struggles to keep a grip, Max jumps on Phantom, stretching out his mouth. But Phantom was pulling on the lid, and soon it popped off, sending the Egg flying. May drops the container and dives in to catch the Egg. Ashley manages to catch up at this point, but the Egg begins to shine. Then the entire Egg glows white before two antennae come out, and when the glow fades away, Manaphy is finally born. It opens its eyes to see May, but begins crying. May tries to calm the newly born Manaphy while the Captain is disappointed that something like Manaphy was the treasure he was looking for. But even so, he's not about to give up that easily and begins to make his move. Jackie comes in time to keep Phantom busy enough for Ashley, May, and Max to escape. Jackie follows shortly afterwards and the four find the trailer which Brock and Lizabeth managed to get back to beforehand. Jackie stays behind as the others get on to ambush Phantom to delay him once more.
The trailer takes off, leaving everyone to wonder about Manaphy. It slept in May's lap, happy and peacefully. Meredith wanted to try holding it, but as soon as she held it, Manaphy began crying. After Meredith gave Manaphy back to May, it stopped crying and was happy once again. They begin to wonder if Manaphy has imprinted May as its mother, considering that it was the first thing it saw. However, Phantom is once more on their tail, and two helicopters launch grappling rods to keep themselves affixed, and also to slow the trailer down. Ship comes in from the front car, telling the others inside to get in. Meredith first goes in; helping May so she doesn't fall. Brock then steps out to help Lizabeth, followed by Max and Ash. Ship gets out last as he unlatches the trailer. This sends the helicopters flying backwards, momentarily losing control as the trailer careens off a cliff. The choppers manage to cut their grappling lines and regain control.
The gang heads down into to ruins, deeper until they reach what appears to be a dead end. Ship however holds his bracelet of seashells near a gem in the end wall. It glows to resemble a combination lock. He slides it to the right combination and a door opens up. Kai asks everyone if they have water Pokémon, since they'll be traveling down a canal. A few minutes later, Phantom steps down into the ruins, coming across the same dead end. However Phantom knows of this somehow and he pulls out a similar bracelet from his pocket. To his disappointment however, he comes across the canal, but there's no way for him to go.
As the gang swims down the canal, Manaphy is enjoying its time in the water. They soon come up to another wall, in which is decorated with murals that tell a legend. Ship explains that there was once Ocean Temple named Samiya where water Pokémon and "people of water" had resided, and where a "King of the Sea" lived. However, evil spirits began invading, and so the king used his power to protect the temple, he encased it in a bubble and took it below the ocean. However normally it cannot be seen, but when its time for the "Prince of the Sea" to return, the moon will glow red for a brief period and Samiya will be visible. But there's a time limit once the Prince is born to return. Manaphy is this "Prince of the Sea", and so Ship plans on leading them to a port town, where he'll have a boat waiting to take Manaphy to Samiya.
Meanwhile, Phantom tries to find a possible idea to where the gang could've gone. But as his right hand man attempts to map out the route, the canal suddenly branches off into many different paths. They'll just have to spend their time finding out where they've gone.
The gang reaches a port town, where they wait for a while as Ship's boat comes along. They take a moment to rest and enjoy ice cream. Manaphy is now asleep in a bassinet, probably tired after all the swimming. Ship quickly finishes his cone as he spots his ship coming in, and warns the others that it's arrived. At the port, three of Ship's old shipmates Gabu, Dabu, and Zabu step out to greet their old friend, and they want to go with Ship on the expedition to Samiya though he doesn't tell them that specifically. Ship of course introduces the gang to his old shipmates, as he used to be an avid adventurer of the seas in his boat Blue Lagoon. However, Ship only takes his family, Jackie, and Manaphy along. May is upset at this, but she knows that it's for the better that Manaphy gets released. Gabu, Dabu, and Zabu though encourage May to stop them so she could get on, and Ashley, not willing to put off an adventure like this, also joins in with May to stop the boat.
Manaphy on board soon wakes up and Jackie tries to comfort it. But it soon shoots out a red lighting that hits Jackie, and then trails down into the ocean back to the port. It travels towards Ashley and May, and then suddenly Ashley gets his foot caught by the lightning. Then, Jackie and Ash switch bodies, leaving them confused. Manaphy is happy though to see the Jackie Ashley, but the real Jackie continues running towards the end of the port.
Later on, the gang gets on the boat, Jackie and Ashley exchanging comments about that weird experience they just had. Jackie however says that this is one of Manaphy's powers, Heart Swap. Ship then tells May that Manaphy is referred to as the Prince of the Sea. May asks Manaphy if the reason he switched Ashley and Jackie was so they wouldn't leave without her. Manaphy nods happily while May gives him a nuzzle on the cheek, saying he makes her happy. Manaphy then says happy, leaving everyone to the excitement that Manaphy can talk. Meredith recalls Lizabeth's first word which was apparently "Fu Fu," meaning food. Ship then says she loved to eat and Meredith chuckles. Ash and Max try to get Manaphy to say their names, but Manaphy resumes speaking out its name. Manaphy then rubs his flipper on May's cheek and she hugs it, saying that its cute. Jackie looks at them bonding, obviously not pleased about Manaphy getting close to May. Ship says that Manaphy needs to guide them to Samiya, and that Manaphy has to be released into the water. May lets Manaphy back into the ocean, and it jumps around swimming freely.
As Manaphy swims by, Ship brings the gang down to a lower part of the boat. After releasing a hatch, a dome in front of them opens up to reveal an underwater forward observation room. And they see Manaphy swim by with the various ocean faring Pokémon. Manaphy sees May and tries to swim up to her, but it hits hard on the glass dome. It begins crying but May tries to comfort it and Manaphy is once more a happy camper. Days pass, Manaphy still following the Blue Lagoon, trying to call out to May every so often. Jackie still sees some disproving in this, as if Manaphy gets too close to May, he may not go back to Samiya. Jackie though is scouting out of the ocean, probably looking for both the location of where Samiya is or perhaps looking out for Phantom. In one instance, he was parasailing to get a much better view. Ashley watched him from below, commenting how cool it must be to be a Pokémon Ranger.
The boat makes a stop over a coral reef and the gang decides to take a swim. Although May seems still a bit preoccupied on the boat still, with Manaphy sleeping in her arms. Ashley gets back on the boat to find Jackie, who hands her a towel as he comes up. Ash asks Jackie how he would decide to become a Pokémon Ranger. When Jackie was much younger, he got caught in a blizzard in his homeland. He found refuge in a cave, stumbling in and shivering from the cold. A Swablu comes down next to him, and he realizes that the cave is filled with Swablu, Altaria, Sentret, and Furret. They all huddle next to him to keep warm, and he stays the night there. The next morning, the storm has cleared up and all the Pokémon begin moving out of the cave. After seeing the flock of bird Pokémon take off, he was interested in Pokémon life, and wanted to defend such, and so he's been on adventures. After hearing that story, Ashley removes her clothes revealing her swimsuit, She gets a bit excited and she soon jumps back into the ocean, with Buizel. May goes in as well with Manaphy, and the both of them explore the coral reef together. They both resurface and May cuddles Manaphy lovingly.
Later that night, May is sleeping outside with Manaphy on a hammock. She tells Manaphy that she loves him, and asks Manaphy if he can say "I love you." Manaphy looks at her with a questioned look on his face. May then helps him out by saying "you." Manaphy almost said it, so May repeats "you" one more time. Manaphy finally learns and says "looove you!" May praises Manaphy, and Manaphy says happy. May affectionately hugs Manaphy while Manaphy tells May he loves her. Jackie is watching from above, and is very concerned about the relationship between Manaphy and May.
Later the next day, Brock is cooking a meal with Meredith, who finds his cooking to be very impressive. May is seen walking down the hallway towards the underwater observation when she hears Jackie talking with Ash. He tells Ashley that Manaphy being all cuddly with May isn't such a good thing. After all, Manaphy is supposed to be the Prince of the Sea, a leader. How's a leader going to look if it acts how it does to May? At that, May suddenly comes in, telling Jackie that Manaphy will still do a fine job being a leader, and then she rushes out just as Lizabeth was about to enter. Manaphy is outside the boat, trying to get May's attention as May is curled up against a hallway wall. Lizabeth finds her and tries to console her, as May doesn't seem to want to let Manaphy go. To help her feel better, Lizabeth gives May her sea shell bracelet. Later that night, Manaphy sits on a rock, looking at the moon. It begins to sing, and as it does, Pokémon begin crowding near Manaphy. It seems Manaphy has influence on the Pokémon and perhaps its relationship with May hasn't hindered its position.
