Creation Era

His name was William Jack/Jack William. At least that's what Arceus told him when he opened his eyes. William was born from the world's need for fluid and Adauoa [Water Type Primal]. Being Adauoa's champion, William was the Splash Plate. What was his purpose? He was to create water, as it was the main constituent of Impar's seas and the fluids of most living organisms. William was an adventurous plate. Through those bright eyes of his, he was always trying to find the whatever new thing added to the world with his Setmates (Meadow and Flame) following close behind him to ensure he was safe. After all, William always had a knack in sticking his noses in places that always lead to trouble. It was something he never worried about. After all, he was the descendant of God! What did he have to worry about? When humans were introduced into the world and begin to travel by sea, William became interested in a specific group of them. They wore eyepatches and spoke in a language that interests him. They were the thieves of the sea and were separate from the humans of land. Through watching them, William imitated their nature. He wanted to be as cool as them. Whoever they were appealed to his adventurous attitude and sparked something in him to give him an identity that would make him stand out.

This is where Captain William Jack was born.

When it came to William's relationship with the plates, most regarded the male as being a child. He was quirky and brought a smile to everyone he met faces. To Flame and Meadow, he was the best little brother they wanted. There was never a day where the two weren't together, embarking on some secret mission under Arceus' nose. The three love each other to the point and had an unbreakable bond. However, it was a bond that would be tested for years.

It happened one day when Flame, William, and Meadow spent time watching over the humans of the sea. The human of the seas were individuals who traveled the sea through the use of boats. The three plates always watch them as it was something William enjoyed. As they watched them from a little boat they found, they noticed the humans were attempting to hunt down Kyogre. The smaller legend had been attempting to protect a Pokemon it had befriended and was caught in the fray. It was William's duty to protect Kyogre as he was bound to him. As such, Splash, Meadow, and Flame distracted with the humans of the sea, so Kyogre would be able to flee from the fray. However, there is something learned that William would learn to never forget: When humans feel trapped, they react out of desperation and madness. It was proven to him after he witnessed the humans kill Meadow and Flame. Meadow was impaled in the back by a pirate from behind and had fallen in the sea. Flame had shielded William from the rain of attacks that were sent towards him as he stood stunned. He had effectively thrown away his own life for him.

The pain of feeling the death of his setmates and the anger brought out that primal animal that Arceus had told William to control. An animal that William allow to take over as he wanted nothing more than eliminate these humans. This animal did just that. He drowned them. He stripped away their body fluid. He did everything he can to ensure they wouldn't come back. He did everything to ensure they felt the pain that he felt from losing his setmates. He kept going until the sea around him was painted red with their blood, and nothing remained. Once nothing was left, he got down on his knees and cried as he cradled his Setmates bodies. That's all he can do.

To his relief, Meadow and Flame came back, but it wasn't them. New people took their place and held their titles. It was them, but not them. It was the curse of reincarnation. While a plate couldn't die, they gained new identities. Sometimes, they kept their memories. Sometimes, they don't. It was honestly a coin flip. Splash did try not to let that bothered him, but it was hard. They weren't his Meadow and Flame. They didn't look like him. They didn't sound like him. They weren't there. They changed, and it was all his fault. All of it. Not wanting to associate with the fact he potentially leads to Meadow and Flame's death, he stopped associating under the name 'William' to the following:

Captain Splash, the Bloodied Captain of the Seas.

The deaths of Meadow and Flame brought a level of paranoia that grew as more plates died and came back. Would he be next? How would he die? Who can he trust? What about the others? Are they safe? Are they ok? When Meadow and Iron were killed Zap (and Flame and Meadow reincarnation killed each other), this brought him a level of anxiety over the potential idea that those who consider his family could kill him. This lead to the male developing a strange relationship with his fellow plates. For those who died, he would be protective of them. For those who didn't die, he would express a form of wariness over them. Those who died were a member of his 'crew' while those who didn't would be his potential enemy. This strange dynamic would be shifted when Mr. Spooks is introduced.

Splash wasn't in love with Mr. Spooks. He partially disliked the male due to his inability to die and how flirty he was. However, spending time with the male brought him a form of ease. Perhaps it was because of how jolly he was, and his brain giving him this idea that Mr. Spooks could help him avoid death due to his reaper status. What started as a one-sided lust blossomed into a mutual lust that they satisfied through their one-night stands. Again, there was no love. They were using the other as a form of stress relief. However, it was through his bond with Mr. Spooks, Splash learned to (somewhat) not allowed death to stop him from enjoying the relationships he had with his fellow plates and what life has to offer. It's something that Splash spent the next few decades attempting to do. It's slow progress with his paranoia, but it's something that he doesn't mind.

POA Era-Pre Rotom Era

When the day came for Damian and his group to save Shimera, you best believe that Splash was there for that. Granted, it wasn't like he had a choice since the plates were more or less Damian's weapons. However, Splash had partially returned to his roots as William as he developed a knack to getting himself (and the others) in trouble. This lead to the male developing a reputation of being the troublemaker of the group. To this day, Splash will argue that luck is known to be incredibly shitty. Granted, this could be his paranoia, but given everything, he could be right.

Between Creation Era up to a certain part of the POA Era, the relationship of Zap and Splash has always been a rocky one. For one thing, they were natural enemies of each other. Zap carried a type advantage over Splash and embodied what it meant to be a ninja (the natural enemy of pirates..at least according to Splash). Another thing was Zap was starting to see why Splash was a troublemaker of the group and had a bit of jealousy when it came to the fact the plates still liked him because of that. He wanted the plates to like him similar to that. The last thing was the fact Zap did kill a version of Meadow and Nor (and nearly Mind). Considering how much Splash cares about them (especially Meadow), it makes sense that Splash would have a disdain for the male. Zap wished that wasn't the case. As such, it was no secret that Zap and Splash always had that rivalry for each other. There was never a moment where two weren't trying to one-up the other.

As they continued to work together as teammates, Splash came to view Zap as a brother. He realized how Zap was remorseful for what he did to Meadow, Iron, and Mind and was doing whatever he can to try to move past it. It was similar remorse that Splash feels for (potentially) causing Meadow's and Flame's first death. The rivalry between the two became more friendly, allowing them to converse casually and make jokes about their dynamic. However, this friendship would more than that as the two fell in love with each other. He's not sure how it happened, but he didn't know what to do. What if he didn't return his feelings? What if he wasn't into dudes? What in the world was he going to do? He even asked Mr. Spooks how to deal with this.

"Just tell him."

Splash didn't tell him because this male's confidence was very low. How can someone just say it was beyond him. For weeks, he tried to bury his feelings as a means to try to move on. However, it was impossible. No matter how hard he tried, the male couldn't stop thinking about him. He couldn't stop thinking about his smile, the way he carried himself, and everything that made Zap attractive in Splash's eyes. It made him more desperate to learn how Zap felt about him. If he knew, then he could be free of not knowing where Zap's feelings lay for him.

On the bright side, he didn't wait long.

During the group's adventure in Hoenn, they would eventually battle Kyogre. Much like most battles with the legend, it was not a fun one especially when Kyogre assimilated Splash into him. The assimilation sent Splash into a form of unconsciousness that lead him to relive his past. Amid the chaos, it was Zap that freed him from his mind. Even as the group struggled to remain standing on the ship they found, Zap stood there and yelled at how he was going to free Splash from Kyogre even if it would cost his life. He called out to Splash and pleaded for him to 'wake up' so he can be with him, touch him, and love him. It's corny, but the idea of not knowing where Zap feelings laid him for him was something that haunted Splash. It sent his mind spiraling and added onto his paranoid thoughts. To hear Zap's words and finding out the male love him removed the weight on his chest that been haunting him for weeks. Splash managed to wake up and free himself from Kyogre. Once Kyogre was weakened, Zap didn't even get a chance to even speak to Splash as the water plate had quickly kissed him.

Thankfully, it seemed as if that answered the question on his mind.

Splash became fiercely protective and overly affectionate of Zap. Hell, he even became bashful in his presence. He experienced a special kind of happiness he had never felt before and realized that his being was irreplaceable and essential to him. Of course, he had to battle with himself. After all, Zap was the one who killed one of Meadow's incarnation and Iron's incarnation, so one side of Splash was coming in terms with the fact he fell in love with their killer. However, Zap was patient and allowed Splash to take his time in fully accepting his love. Regardless, the two would continue to date through the years. Something would occur that would bring the two closer.

Damian's fall occurred after the male was hit with Naoto's move and sent flying off a cliff. Falling into a coma, Damian was teleported away from Mi to an unknown location. However, the plates themselves were panicking as the damage done to Damian's body was severe enough that he was lying close to death's door. While he did have the benefit of reincarnation (thanks to his guardian status), the plates didn't know what would happen to them when Damian died. There was also the concern that Yveltal wouldn't be fast enough to save him. For that reasoning, they decided to fuse with Damian. While this did mean Arceus would no longer be able to use them as they were stuck with Damian, they didn't have any other options or the time needed to reflect on them. Giving a silent apology to their Creator for what they were going to do, these elemental spirits fused themselves into Damian, becoming one with the male.

Rotom Era-Our Story Era (Now)

During the months Damian was in a coma, Splash grew closer to Zap and used this opportunity to learn about the male. Through his bonding with Zap, Splash would slowly welcome his old identity as William Jack. The two would have a few bumps in the road with Zap becoming permanently infected with the shadow virus and the two having to adapt to it. After all, Zap being infected resulted in others being slightly wary of the male due to the damages those of the shadow nature can cause. Despite this, Splash stood by Zap's side, refusing to allow him to deter him from loving Zap. Hell, he even went out of his way to convince those others that Zap was one of the good shadows.

When the "War of Providence" ended, Splash and Zap spent time bonding over the years with Splash doing what he can to help his mate get adjusted to being a shadow. Splash's terrible reputation has vanished as the male has grown from that. His fear of dying has somewhat gone away with very few deaths occurring with the plates. However, this isn't to say it's completely gone. He's currently happy where he's at. Now in terms of kids, the two has twins (William and Haru) sometime around during the Our Story Era.
