Alverna: This is just an idea that has been biting at me for a long time. I don't own Yugioh or Barbie in a Mermaid's Tail. Enjoy.

01-25-2013: Hey everyone, I'm editing this story to take care of grammar and spelling errors. Also, the first chapter is changed, I added more duel details, (life points, monster attack and defense, etc.).

I'm also aware that SuperSpeed was inspired by this story and is doing their own twist to it. I'm fine with it.


Chapter 1: The King of Games


It was a sunny day in Los Angeles, California. Even more so at the Malibu beachfront, where the Duel Monsters Surfing Competition was being held. So far, the elimination process was doing its job. Many good duelist, but poor surfers, had been knocked out early that morning.

Right at that very moment, a black haired female had entered the tunnel of water after summoning her Dragon Lady to the field, and strengthening it after playing Flying Dragon Whirl, sending four of her dragons in her deck to the graveyard, booting the attack to 3700. With this her opponents attack was 700 points less than her.

The brown haired teen with piercing blue eyes, was thankful for his Negate Attack trap card as it stopped Dragons Lady's attack, forcing Vivian to end her turn.

Seto Kaiba was wearing a dark blue wet suit with a Blue Eyes White Dragon on the front. He had an icy blue shell necklace, the same color as his eyes, on a silver chain.

He knew his three Blue Eyes White Dragons did not have enough attack. He needed to draw the right card and he needed it now.

"Yes!" Seto shouted, and slapped the card on his Duel Disk, a machine of his own invention. "I play the magic card Polymerization. This combines my three Blue Eyes White Dragons and combines them into Blue Eyes Ultimate Dragon."

The Blue-Eyes Ultimate Dragons attack stood at 4500, enough to wipe out the Dragon Lady Vivian had played, and take out the rest of her life points.

"Blue-Eyes Ultimate Dragon, attack! Neutron Blast Attack!" Seto shouted as the blast shook the people on the beach, and knocked Vivian off her surfboard.

"Oh! And that's it for Vivian Wong folks. She is done." The announcer said. "Seto Kaiba is in the finals and has once again proven who he is as a duelist."

Seto was the one who had made the duel disk and had introduced it to the surfing world, what his rival often did if he wasn't at the arcade. Seto gave a short nod to the cheering people before turning his attention back to the water, where his rival and teammate in this competition sat waiting.

"Next up for the championship trophy is," the announcer paused, "Malibu's own King of Games, Atemu Yami Sennen!"

At the sound of his name and the cheers from the people on the beach, Atemu Yami Sennen, Yami to those who didn't have a death wish, turned and waved.

His solid black hair set off his crimson eyes that sat in his tanned face. His 2 piece wet suit that reached to his elbows and knees sported his most favorite duel monster, Dark Magician. His black swirl shell necklace was held around his neck with a basic piece of twine.

"Come on Sennen, let's go already!" Yami's opponent, an annoying person by the name of Rex Raptor called out.

"Yami has been in and out there all afternoon." The announcer said. "With only one more minute to get standing and going, will he find the wave he's been waiting for?"

A beep on his right wrist caught Yami's attention. Giving Rex his trademark smirk, he answered the call. On screen were his two best friends. The one with downward spiking white hair and dark brown, almost black colored eyes was Bakura. The one standing next to Bakura, with lavender colored eyes, and semi-spiky, slightly sanding up white-blond hair was Marik, who was arguably the more insane of the two.


(A/N: I know this isn't what they look like in the anime, it will be explained later.)


"Well is he?" Bakura asked.

"Yeah." Marik added. "You're gonna be disqualified it you don't get moving, despite having a spot already. Rex still needs to make his run and you're his opponent."

Yami looked back behind him and spotted what he had been looking for.

"I think I just did." Yami told his friends.

"No way!" Bakura said when he saw the wave. "You're gonna be pounded fish guts if you try that one."

"See you back on the beach." Yami said, and cut communication as he started towards the shoreline.

"Are you insane?" Rex Raptor shouted.

"It's up for debate, considering who my friends are." Yami called back as his duel disked fired up. "But I'm going to win. Especially if you don't get moving. You'll be disqualified."

With the threat of going out in disgrace hanging there, Rex paddled to catch up, activating his duel disk. Even if Yami wiped out or lost the duel, he would still be in the finals tomorrow, having won three duels already that morning. To him, this run was just for fun; Rex however, needed the opponent. But if Rex wiped out or lost to Yami, he was out for good.

"I don't believe it!" the announcer shouted. "Those two are going to take this wave in."

"You're the King of Games!" Marik shouted as the wave picked up the two surfing opponents.

"Go Yami!" Bakura cheered. The announcer started a song that had been requested by Bakura and Marik to play when Yami did his run. The two started to dance and sing. It was their own weird way of cheering for their friend.

The duel started with 8000 life points for each player.

"He's ready, he's steady

He's up on his feet

Dueling on the water

To his own kind of beat."

Yami smirked back at Rex who was having a hard time staying up. Turning his attention back to the game, he drew his cards, and waited as Rex summoned Trakodon, 1300/800, to the field. Yami grinned and summoned Celtic Guardian, 1400/1200, placing Mirror Force face down on the field. Focusing on carving the wave, Celtic Guardian attacked.

"He's in it; he's on it

He's rockin' the skills.

Tearin' up his opponents

And going for the kill."

Rex growled as Trakodon was sliced and diced by the Celtic Guardian, dropping his life points to 7900. Drawing his next card, he grinned and placed Megazowler, 1800/2000, on the field. Calling for an attack, Megazowler effectively destroyed Celtic Guardian, lowering Yami's life points to 7600.

But Yami wasn't fazed a bit. He had been expecting that, and again reached for his deck.

"Draw cards

Leanin' side to side.

Summon your monster and

Go for a ride."

Yami gave a small smile as he summoned Feral Imp, 1300/1400, into the game. It was 500 attack points weaker than Megazowler, so it was equipped with the magic card Horn of the Unicorn, raising its attack to 2000 attack points, 200 attack points higher than Megazowler.

"Catch that curl

Get into the groove.

Take out your enemy and

Make your tail fin move."

"Having fun yet, Rex?" Yami smirked as he had Feral Imp attack.

"Uh-oh." Rex was all said as Megazowler was destroyed, life points dropping to 7700.

"He's the King of Games!

Check it out he's spinnin'

That board around.

King of Games!

No one's gonna

Take away his crown."

Rex growled as he drew a card and cursed, it would not help, so he ended his turn.

Yami grinned and drew again. "I place Kuriboh, 300/200, in defense mode, and have Feral Imp attack your life points directly. Now I place one card face down, and end my turn."

"Surf's up, bow down.

He's the King of Games!"

Rex hissed as his life points dropped to 5700, drew his card, and smiled. "I play the magic card Chain Summon. Now I can summon three monsters on to the field. I choose Two-Headed Rex King, 1600/1200, Crawling Dragon # 2, 1600/1200, and Serpent Night Dragon, 2350/2400."

"Yippee." Yami rolled his eyes at Rex's drama.

"Now Serpent Night Dragon," Rex glared at Yami, "take out his Feral Imp. Two-Headed Rex King, attack his Kuriboh." The two faithful monsters on Yami's field were destroyed, lowering Yami's life points to 7250.

"Draw cards

Leanin' side to side.

Summon your monster and

Go for a ride.

Catch that curl

Get into the groove.

Take out your enemy and

Make your tail fin move."

"Crawling Dragon # 2, attack his life points directly." Rex shouted and Yami smirked. "What's so funny?"

"You fell for my trap." Yami said. "Activate Mirror Force."

"Ahhh!" the crowd gasped as Yami pulled off an amazing cutter while Mirror Force wiped out Rex's three monsters on the field.

"My turn." Yami said as he drew. "Now I call forth my Dark Magician, 2500/2100."

"Oh no!" Rex cried.

"He's the King of Games!

Check it out he's spinnin'

That board around

King of Games!

No one's gonna

Take away his crown."

"Attack his life points directly. Dark Magician, Dark Magic Attack!" Rex's life points dwindled down to 3200. "I place one more card face down and end my turn."

Rex growled and drew, setting Red Eyes Black Dragon, 2400/2000, in attack mode, and added the magic card Dragon Nails, boosting Red Eyes Black Dragons attack points to 3000. "Attack, my Red Eyes!"

"Trap card, Negate Attack." Yami said and activated the face down card he had added when he played Kuriboh.

"No!" Rex growled as he ended his turn and watched Yami draw a card.

"He's the King of Games!

Check it out he's spinnin'

That board around."

"Activate magic card Magic Formula." Yami said as he played the magic card, making Dark Magician's attack point total jump to 3200 attack points.

As Dark Magician attacked, some ocean water splashed onto Yami's head, which he promptly ignored. He also didn't notice that the edging of his hair turn a bright crimson color, and his bangs turning blond, along with the three lightning-bolt streaks that ran up his hair. The rest of his hair remain jet black.

"King of Games!

No one's gonna

Take away his crown.

Surf's up, bow down.

He's the King of Games!"

With Red Eyes Black Dragon destroyed, and 3000 life points remaining, Rex didn't have a strong card in his deck that could destroy The Dark Magician. One more attack and he was finished. Then he noticed Yami's hair.

"Did you get a new hair dye that reveals itself after getting it wet with ocean water?" Rex asked snidely.

Yami rolled his eyes and faced forward again. Rex Raptor's comments were not going to make him loose his focus or the duel.

"WHOA!" The announcer shouted. "Check out Yami's hair! It's changed color!"

"What?" Yami said out loud, and he grabbed one of his bangs, shocked to see it a golden blond color, not the black he was used to seeing every day in the mirror.

"Blond and crimson hair?" the announcer was talking to himself but he had left his mic on. "What is going on here? And when did he go to the gym?"

Yami's eyes had widened in shock as he glanced at his body. It had become well-muscled, like someone who lifted heavy weights from day to day. Something he did not do. He ran on a treadmill.

The sound of Rex's board coming closer along with a magic or trap card being placed down, (most likely trap since Rex had no monsters on the field), spurred Yami into the tunnel of water. Rex growled as the tunnel of water folded in after Yami entered, so he followed on the outside, staying close to Yami's shadow as best he could. But Yami had positioned himself to be faster than Rex, but not fast enough to speed out of the tunnel for a minute or so.

"What's going on?" Yami said aloud. He often did when trying to solve a hard problem.

"It's Yami's turn." Yami heard the announcer threw the wave. "But he has to get out of the tunnel first. And I want another look at that gnarly hair."

Yami's breath was caught in his throat. He couldn't explain what had happened. The end of the tunnel was coming quick. He could ride out of the tunnel, take out Rex, and then try to explain what had happened, or he could…

"OH! Rex Raptor could not keep up and wiped out." The announcer called out.

'Wipeout!' Yami thought, dove into the back off the wave.

"OH!" the announcer shouted as Yami's board flipped above the wave. "Looks like Yami has also wiped out."

Bakura and Marik gasped. They looked at each other. Both of them knew Yami had done that on purpose. Looking back out to the water where Yami's board was, they waited and breathed a sigh of relief with everyone else as Yami waved from behind his board.

"He's okay everyone." The announcer confirmed for those who couldn't see. "Just a reminder that Yami Sennen is in the finals tomorrow. This last run was for Rex Raptor to have an opponent. Now the rest of you surfing duelist, come on in."

Yami dove under the water, wanting to figure out what happened, and not ready to face the 'fan club'.

"Let's go." Bakura said as he and Marik looked at each other again. The grabbed their boards and went out to where their friends board was.

Under the water, Yami had swum down to near the sand. He stopped and grabbed some of his hair again and looked at it. What was he going to do?

"Hi there!" a child-like voice said behind him.

"Huh?" Yami turned around and gasped. There was a young boy, well, he looked like a boy, but Yami knew from experience that height and looks can throw off what your real age was.

"Yes. I'm talking to you." the boy giggled.

He had pale skin opposed to Yami's tan, innocent amethyst eyes, and hair that looked just like the way Yami's was now. The only difference was it was tipped with amethyst instead of crimson, and he had no lightning streaks running up his hair.

He wore a black tank-top that showed his abdomen, which appeared to be made out of leather, a neck belt, some wrist bracelets, and 3 silver chains that hung loosely around his hips.


(A/N: Look at Episode 53, 'Steppin' out.' Slight difference with the top.)


But the major difference was that he had a beautiful amethyst tail where his legs should be. He was a mermaid. Merboy. Whatever.

"Uh." Yami was speechless when he realized what the boy in front of him was. Then he realized he was breathing out his air. His hand flew to his mouth, not wanting to lose anymore.

"It's okay." the boy swam over, pulling Yami's hands away from his mouth. "You can breathe underwater." Yami only stare at the boy, who looked up. "Your friends are worried you."

Yami looked up and saw Bakura and Marik looking down into the water as they sat on their boards trying to find him. But Yami wasn't ready to talk about what happened. He felt so lost and confused.

The merboy smiled at him and took his hand, gently pulling him upward. Yami didn't even realize he was swimming until he was a few feet away from the surface.

"You should talk to them." the merboy spoke to Yami, and began to swim away.

"Wait!" Yami shouted. "What's going on?" The merboy turned and gave a small grin that seemed to easy some of Yami's stress.

"I'll explain later." the merboy called back. "Go to your friends."

The merboy disappeared into the blue water.

'I don't even know his name.' Yami realized.

Taking a deep breath, he propelled himself upwards. As his head broke the surfaced, Yami gasped in fresh air on instinct.

"Yami." Marik said, relieved to see his friend. "You're okay."

"Whoa." Bakura's eyes went wide. "Radical hair dude."

"Bakura." Marik leaned over and smacked him upside the head.

"Well it true." Bakura protested. "And weird. A cool weird, but weird."

"It's okay Marik." Yami stopped his friend from smacking Bakura again as he rested his arms on his surfboard.

"You feel okay?" Bakura asked, concerned. Yami would usually protest when Marik or himself said something like that.

"Yeah." Yami said unconvincingly. "Some weird things just happened."

"Like your hair." Marik said.

"Yeah, but this was a bit weirder." Yami said, and Bakura and Marik stared at him with full attention. "When I was underwater, I was breathing. And then I spoke with a merboy."

Bakura and Marik looked at each other then back at Yami.

"We had a conversation, kind of." Yami looked up at his friends after a lengthy pause. "I just became the most insane here, didn't I?"

"Maybe." Bakura answered.

"Mysterious colored hair, a new body build anyone would die for, breathing underwater, and a merboy!" Marik listed off as the grin on his face got bigger. "There is something deep and intense going on here."

"Yeah." Bakura agreed. "Like a deep, intense concussion."

"Oh come on." Marik whined. "I'm tired of being the most insane here."

"I'm fine guys. It's just been a long day." Yami said as he pulled himself onto his board. "I'm going to head home."

"Okay." Bakura said. Still unsure if his friend had hit his head, he called after him. "But if you get sudden blurred vision or a killer headache, have Solomon take you to the doctor."

"Or the arcade!" Marik called after Yami.

"The arcade?" Yami and Bakura questioned Marik at the same time.

"I love the arcade." Marik responded with a dreamy look in his eyes.
