(A/N)

This is my First attempt at Fanfiction. We will be following the Isekai story of a young man who is turned into an even younger boy while being inexplicably summoned into another world. That world is the Yu-Gi-OH ZEXAL world. Although I hope to use Synchros, Pendulums, and Links, I will try to keep the references to other shows restricted to the Isekai Character(s). I have hopes to expand this story beyond a single chapter. Please feel free to give any criticism of my story. (Note: Although I do play the game, I am not completely aware of the release dates of all cards. I may resort to the excuse of saying the cards are released at different times in the anime vs IRL. With that said, enjoy the story)

(MC POV)

"Dan? Dan? Hey are you still in there? You got a response?." Kamron waved his hands at the blank faced Daniel. "Huh? Oh. Sorry Kamron, but I was just thinking." The blank look on his face unwavered. Kamron stopped and walked over to Daniel. "C'mon let's keep going. I think I finally have you on the ropes." Dan looked at the field. "Wow" he said sarcastically. "You actually managed to XYZ summon". Kamrons expression quickly changed. "Oh yeah? Well from the looks of it, I'm finally going to take your crown. You should be scared." "Yeah okay." Said Dan "I might be scared if this wasn't the first time you XYZ summoned in the last 5 games". Kamron snarled. "Alright then! If you think you got this then I'll have my newly summoned "Shining Elf" (ATK 1600/DEF 1000) attack your "Red-Eyes Wyvern" (ATK 1800/DEF 1600)!" Daniel facepalmed as the shinny elf swung his katana at the dragon, only to have the sword miss its mark as the dragon bit down on the sword, and then threw the elf back to his original position. "Wait! What? How come he's still on the field?" Dan explained in a mumbling breath. "When a monster attacks Defence position monster with DEF points equal to the attacking monsters ATK points, neither monster is destroyed." Kamron stared with a dumbfounded expression, then quickly snapped back "There's no way that can be a rule. You must be cheating!" "Yeah haven't heard that one before." Dan rolled his eyes. "Do you really want to go to the rulebook again?" "No" Kamron mumbled. "Good, in that case, it's my move. Draw. I summon "Red-Eyes Retro Dragon. (ATK 1700/DEF 1600) Now I'll overlay my two Red-Eyes monsters, and with these two monsters I build the overlay network. I XYZ summon "Evilswarm Thanatos" (ATK 2350/ DEF 1350)" A dark knight charged onto the field riding a white armor covered horse. "And if you do the math right, you'll notice that I have just enough ATK points to finish you." "Not so fast" Kamron smirked "I activate my elfs effect. By using one of its overlay units, I can make your monster lose 500 ATK points, so I'm still in this." "Are you sure about that?" Dan retorted. "By using one of my monsters overlay units, I can make it immune to your monsters effects." Kamron quickly grit his teeth, as Dan readied his hand. With a slight wave of his hand, Dans monster attacked Kamrons and brought the duel to an end. (Dan 4000/Kamron 0)

"Aww man, and you didn't even break a sweat. Huh?" Kamron turned his head to see Dan wandering off. "Hey where are you going?" Dan continued to walk. "C'mon this isn't because I dared to mention the audacity of beating you is it?" Dan paused. "I don't think it's such a bad thing to lose, it's just that… well...hmmm… I guess I kinda want to lose". Kamron looked shocked. "Why would you want to lose? You're like the best duelist in the entire city, heck probably the whole country. You basically have your whole life set with how good you are, so why would you want to lose all that?" Dan thought for a second. "Maybe… I don't want to lose, but rather feel like I earned it, y'know what I'm saying?" "Oh, you mean you want a real challenge?" "I guess." "Alright then. Let's go find one!" Before another word could be said, the two boys teacher walked up. "Mr. Marsden, would you please follow me?" "Uh oh Dan, what did you do this time?" Kamron teased. Dan ignored the comment and went with the teacher.

As the walked Dan continued to think about the circumstances of his being in the world. He had literally done nothing to get here on his own. In his mind it was still the weirdest thing to think about. He merely stepped into a closet when suddenly there was another world on the other side. Not only that, but in fact he had become about 2 feet shorter, and aged backwards about 10 years. Fortunately he was adopted quickly by a loving family, although he appreciated them, he felt really awkward about it. Honestly the best thing about being here was the bizarre anime hair he developed. It was Purple and it had 3 spikes that curled down at the middle front of his head, with the middle most one being much larger and having a blue zig zagging streak down it.

When they both got to the principal's office, he quickly noticed that something was off. In the corner sat a gentleman with a black coat and appeared to be a toothpick in his mouth. Dan couldn't help but laugh at the sight. The gentleman stood up and shook Dan's hand. "Well now here's the famous kid prodigy I've heard so much about." "Yes" Dan said "And you are?". "My name is Malcom Farns. I am here representing the Archive Duel Academy, and we would be more than willing to grant you the honor of joi-" Dan began to walk away ''Pass" "Huh? Wait a second you can't just…" Mr. Farns quickly turned to Dan's teacher. "Dan has turned down every duel school that's given him an offer I'm afraid, from what he's told me, he already knows everything that a school could possibly teach him, and therefore doesn't want to waste his time." "Well" Mr. Farns began while flicking his toothpick. "That will change soon."

"What was that about Dan?" Kamron asked. "You were listening weren't you? Alright fine. You know what? I'm sick to death of dueling! It was fun at first. I felt on top of the world, but now after dueling literally everyone I come across I realized that everyone in this dang town is an absolutely terrible duelist! What's the worst thing about it is that there are almost no other pastimes! So here I am having to do something that sucks for me or just become bored to death doing nothing!" Kamron said nothing. "I'm sorry Kamron, but it's like I said. I just really want to have a hard duel." "Well." Kameron said "Why don't you try to join a pro league?" "Yeah that wouldn't be so bad, but the fact that I'm an 11 year old doesn't exactly make that easy. What usually happens is people will tell me that a kid like me should get experience in one of the "fine" academies. Give me a break. The textbooks they have are a complete joke, and the teachers aren't much better." "Wow really?" Kameron looked at Dan for a while before speaking. "In that case, let's prove them all wrong". "Huh?" Dan stopped "Let's go out there and make a name for you, I know how good of a duelist you are, and I won't stop until the rest of the world knows what I do!" Kamron yelled as he thrust his fist into the air. "Kamron… oh boy. You really are a nut." Kamron slumped over in sadness. "However" Dan continued "Your a nut I couldn't live without being my friend." At hearing this, Kamron sprang up and began to do a peculiar dance, causing his orange hair to bobble up and down. After seeing this, Dan began to chuckle. "Alright then. I'll see you tomorrow then." They bumped fists and went their separate ways.

About a week later, Kamron came charging up to Dan. "Dan!... Dan!.. Hugh hugh." Dan looked at Kamron. "Catch your breath bro, you wouldn't want to end up going home sick again would you?" "Dan" Kamron began. "I found it, I found it." "Found what?" Dan asked, his curiosity now growing. "I found a way for you to make a name for yourself." Dan looked at Kamron blankly before Kamron continued. "Don't tell me you forgot what we talked about last week." Dan paused. "...Oh wait. You were serious about that? Geese, dude i didn't mean for you to go out and find me some big time opponents. How did you even pull that off anyway?" "I didn't" Kamron replied. "I just saw on the news that some crazy dude is using some never before seen monster to attack random people. This is a great chance for you. You can beat him and become a hero city wide." Dans face turned pale. "Dude I never said I wanted to fight crime. I was thinking more on the lines of some higher up academy student, or winning some small time event." "Aww but Dan someone has to stop this guy, he's really causing a lot of people to fear the westside of town." "Look, Kamron." Dan replied. "I appreciate that you're trying to help me here, honest I am, but what would happen if my adopted parents found out? Marcy is already over protective of me. How would she feel if I did something like that? Just let the police and their robots handle it." Kamron looked defeated, but then stood up straight again. "Alright then we'll just make you a superher- oh wait up Dan" Dan knew well enough to dart whenever Kamron got that type of look in his eye, so that's exactly what he did.

When Dan got home his adopted mother went up to him. "Dan, I heard you keep turning down duel academies. Is there any reason?" His adopted father chimed in. "Yeah, I don't like the fact that you aren't using the talent you have." Dan sighed then said. "Sorry I'm just looking for a school that's a bit more of a challenge. Y'know what I mean?" "Oh." The both of them said simultaneously. "Well, hmm, that's good. I was afraid it was for some other, um, reason." Dan smiled. "Well thanks for your concern Howard, I mean Dad." He finished with cringe. "Dan." Marcy replied. "I told you, you don't have to call us by those names if you don't want to." "Right. Sorry. Maybe I should just go check the news."

Dan didn't know why he said that. It was almost as if the TV was calling to him, in a very weird way. As Dan turned on the TV he felt a sick feeling hit his stomach, and watching his hand it almost felt like some of the pixelation of the screen was sucked into Dans' hand. Dans' eyes widened when he saw what was on the news. A crazy man with blood red eyes was laughing maniacally as a large red, black, and white dragon spewed a strange liquid on innocent victims, caused them to cease movement upon contact, and turn their skin into a disturbing pale color. The man shouted at the screen. "You will feel the wrath of the ancient bloodline! Number 24, attack!"

Marcy quickly shut off the screen. "Dan, you shouldn't be watching that, it's not safe for young minds." "I would have found out about it from school anyways." Dan replied. "You mean you would have found out about it from Kamron, honestly why do you even hang out with that crazy kid?" "I hang out with him because he's crazy." Dan said with a chuckle. "To be honest, if you ever met him you'd really like him I'm sure. But anyways, I have something important tomorrow, so if you don't mind imma turn in early." "You sure Dan?" Howard replied. "Yeah I'm sure, later."

As soon as he got upstairs, Dan called Kamron with his duel gazer. "Dude you never told me the guy had a number monster!" "Huh? What's a number monster? Why are you calling me?" Dan straightened himself out. "The crazy guy on the news. If you had told me the card he had was a number, I might have acted differently." "Wow Dan" Kamron stated. "I don't think I've seen you this excited for a long time. Do you think this guy would actually be a challenge for you?" "Never mind that, this guy is an immediate danger, and we have to stop him." Kamron smirked. "Meet up at my house, I got an idea."

"...A scarff and a hat?" Dan said in the most unimpressed way possible. "It's all I could come up with on the fly." Kamron said while shrugging. "Alright." Dan said. "What was that other thing you wanted to show me?" "Oh yeah, I forgot. Follow me". The overexcited boy quickly went over to the wall and pulled out a "hidden" computer. "Secret base! Eh? Eh? What do ya think?" Dan tried to hold in his laughter. "Come on Dan. I can make this work." "Are you planning to help me, ME, with my dueling?" Dan replied while trembling with delight. "Ah, so simple minded." Kamron began. "I'll have you know being a secret agent hero requires more than just dueling skills. It takes someone who knows where the objective is, and knows the layout of the land, or knows what's going on in the world. Let's be honest bro, you may know dueling, but you don't know anything about the world events that go on, and you need navigation." "Ok you got me there. So where do I go?"

Dan had finally reached the place where the place where the attack was occurring. "Man I hate running." He thought to himself before reaching up to his gazer. "Kamron, any news on where that guy is?" "2 blocks north, you'll run smack dab into him." Came the static reply. Upon reaching the place Kamron described, Dan saw that things looked worse than on TV. The man with the number had already taken down 6 of the 7 duel officers dispatched to take him down, and was about to make another kill. "Alright number 24, attack!" The dragon screeched before letting loose a flurry of red blood colored liquid. The officer was now frozen solid, and turned pale white. The man began to laugh. "Hey!" Dan yelled in the best disguise voice he could muster. "Your job isn't over yet." "Dang it, I was hoping I could come up with a better line." Dan thought. The man smirked before turning to face Dan with his duel disk. Dan activated his duel disk as well, but noticed a peculiar glow in man pointed at Dan."My name is Mark Davidson, I think it's only fitting you let me know who you are." "My name is...um." Dan began. "Go on." The man replied. "I'm just a number hunter, my name doesn't matter." Dan was surprised at how well he was keeping his real voice hidden since he wasn't really even trying now. "Alright then, Number hunter" he said in a mocking tone. "Let's go!" The both held up their duel disks and shouted. "Duel!" (Mark 4000/Dan 4000)

"Alright." Dan began. "I'll start things off, I draw." Dan looked at his cards. "I'll start this off by summoning the black stone of legend (ATK 0/DEF 0). Mark started laughing. "You'd summon a monster with no ATK points? You are a fool." "If ya say so." Dan replied. "I activate my stones effect, by tributing it I can summon forth this monster from my deck. Red-Eyes Black Dragon (ATK 2400/DEF 2000)." Mark grit his teeth. "And I'm not done." Dan continued. "I tribute my Red-Eyes Wyvern in my hand to summon, Red-eyes Alternative Black Dragon! (ATK 2400/DEF 2000) and I'm still not done. I overlay my two Red-Eyes Black Dragons." The two monsters flew up and grew into shiny spheres of different colors as they hurled toward a dark hole in the ground. "With these two monsters, I build the overlay network. I XYZ summon Red-Eyes Flare Metal Dragon! (ATK 2800/DEF 2400)." "Not bad." Mark commented, before Dan continued. "I set 2 cards face down and end my turn." As Dan did this he felt the same peculiar feeling of pixelation he did when he was witnessing the event on the news.

"Ha it's my turn kid! I draw!" Mark smirked. "I set 1 card face down in the same zone as 1 of your set cards, next I special summon Mekk-Knight Green Horizon (ATK 2100/DEF 1600). I can special summon this monster if there are 2 cards in the same zone. Also, since you already have 2 cards in the same zone I can summon this. Mekk Knight Orange Sunset (ATK 800/DEF 3000). Now I overlay my 2 level 6 mekk-knights. With these two monsters I build the overlay network. I XYZ summon Number 24: Dragulas The Vampiric Dragon! (ATK 2400/DEF 2800)." "Man that was fast." Dan stated. "I don't know many people who can summon a rank 6 XYZ monster in 1 turn. To bad I don't plan on letting it stick around. I activate the trap Red-Eyes Fang with chain. By equipping this to a Red-Eyes monster, it can make a second attack each turn, but I plan to use the cards other effect. By sending it to the graveyard, your monster takes its place." A bunch of chains shot at the number monster and dragged it over to Dans dragon who unfolded its metal shell to reveal that it was empty. The vampire dragon was instantly crushed inside of the metallic skin. "Pretty clever, hunter. But I activate the spell card De-Spell. This card will destroy my monster." Dan quickly raised his hand. "At this moment, my dragons effect activates. You now take 500 points of damage." The Red-Eyes let forth a small heatwave at Mark as Mark yelled in pain. Dan quickly remembered that in duels like this, pain was real. He suddenly tensed up, then straightened himself. "I can do this." He thought. "So your monster gives me a nasty burn any time I try to do something. (Mark 3500/Dan 4000). I activate the effect of Number 24, if it's sent to the grave, I can set it to my field" The card appeared on Marks field as Dan pointed to it. "In that case you'll take another 500 damage." (Mark 3000/Dan 4000). "It's fine." Mark said. "Everything that has just occured is all worth it." "Dang it!" Dan thought. "I didn't have enough time to read his card. I do know it said something about a flip effect, and it does have the same DEF as my Dragons ATK. If I attack it and the effect activates he'll take 500 damage, also if I attack and it doesn't activate he'll be losing out on that effect." Dan reached his hand for his deck. "My turn, I draw! Red-Eyes take out that set monster." The monster flipped face up and pushed the dragon off of it. "Now I'll use the effect of my vampiric dragon. When it's flipped face up, I can send any card on the field to the graveyard, even if that card can't be destroyed by card effects." Dan was shocked. "Ugh I activate the effect of my Flare Metal Dragon. By using 1 of its overlay units I can special summon Red-Eyes Black Dragon from my graveyard." "Not bad." Mark praised. "And now I'll take effect damage, but I promise you it will be the last damage I take this duel" (Mark 2500/Dan 4000) Dan cursed himself for being too hasty, but then tried to think of a way out of this. Mark had plenty of cards in his hand while Dan had only 1. "I end my turn." "Ha then it's my turn. Draw! I summon another Mekk-Knight Green Horizon. Thanks for summoning that Red-Eyes in that zone hehe. I then activate the spell card snatch steal to take control of your Red-Eyes Black Dragon. Now I'll use your monster to XYZ summon." "But my monster is level 7" Dan stated. "The monster I plan to summon can change your monster into a level 6 monster." Mark replied. Mark then summoned an XYZ monster. "I XYZ summon Dhampir Vampire Sheridan! (ATK 2600/ DEF 1000). Now I'll use one of his overlay units to send 1 card on your field to the graveyard. I think I'll send that set card of yours." "Oh no you don't!" Dan yelled. "I activate the quick play spell, Hyper Refresh. Thanks to this, my life points are doubled." (Mark 2500/Dan 8000) "Well in case you plan on doing anything with those dragons of yours next turn, I'll flip up my face down card. Soul Releases effect will banish all those pesky monsters in your graveyard." "Oh no." Dan thought. "Am I actually going to die here? I don't recall ever seeing a case where a non number user loses to a number user." "Now" Mark began. "I'll have both of my monsters attack you directly" (Mark 2500/Dan 3000). "Alright your move." A strange pixelated glow began to appear over Dan's hand. "Huh?" It guided his hand down to his deck box. "What's this?" A new monster had appeared in his box, but Dan knew it wasn't from this era. "Light Dragon Ignister? This was a card that came out a while ago before I ended up here. Are you here to help me?" He awkwardly asked the card. "Hmmm okay. I draw!" Pixels flailed from his hand as he drew. "I summon Bururu Ignister (ATK 600/DEF 1000)." "The what now?!" Mark asked in shock. "When Bururu is summoned I can send another Ignister monster from my deck to the grave. I chose to send Pikari. Now I activate the spell card Monster reborn. Come to my field Pikari Ignister (ATK 1200/DEF 600). Now Pikari uses its effect. I can add an A.I. spell card from my deck to my hand. I choose to add A. reborn. Now I'll use my Pikari's effect. My Bururu becomes level 4. I overlay my 2 ignister monsters." Instead of the monsters jumping into the air and falling into a black hole as usual, the 2 monsters flew backwards behind Dan. He didn't dare look at what was happening, it wouldn't look cool. The 2 monsters inserted themselves into a satellite looking device before becoming pixelated as 2 lasers fired towards a center point in front of Dan. "XYZ Summon! Come forth Light Dragon Ignister." An incredibly bright dragon covered the field and behind it formed 2 rings in an infinity shape. This was far different from the average XYZ monster. "Now watch closely. I use one of Light Dragon's overlay units to activate its effect. I destroy monsters on your field equal to the number of Ignisters I control. I'll destroy your number monster." "But why would you do that? My monster will simply come back from the graveyard." The monster set itself on Mark's field. "That's the thing I noticed about your card." Dan pointed out. "That card only comes back when it's face up. Now it's face down and is completely vulnerable." Mark grunted. "Yeah but you have no way of destroying it." "I activate A. reborn. This will return my Pikari to my field. Oh and by the way, my Dragon can use this effect again." The second ring disappeared. "I'll destroy both of your monsters this time, and with both of them gone your wide open. Light Dragon, Pikari." Dan nodded to both of his monsters. "Attack him directly and end this duel!" (Mark 0/Dan 3000).

"I did it." Dan thought as he looked over at a nearby window. He saw that his attire changed. He was now wearing a black coat that covered the entirety of his upper portion of his body and was loose around his lower waist. His lower half was covered with red leathery pants and dark blue shoes. His scarf had turned somewhat into a mask that stretched over his nose and went over his ears. His duel gazer had stretched to cover both of his eyes and connected with his scarf. "Huh? What's with this getup?" He thought. The pixels that had formed earlier floated over Mark's unconscious body and pulled a card shape out from him, handing it to Dan. "Number 24. Huh I guess I can take numbers from other people when I win." Dan figured that the reason for this peculiar power was because he was from the real world. Before he could gather himself, the people who were frozen sprang to life. The officers quickly came over to him. "Sir are you responsible for defeating that man?" "I am" Daniel replied. "What's your name then son?" "My name?" Daniel thought for a second. He got into a position to run. "You can call me Cyberse Slayer." Dan took off, and as he did a cluster of pixels formed under his feet into a snowboard shape. It lifted into the air as Dan quickly caught his balance, as to not be seen as a fool. "Wait! Come back!" the officer shouted as Dan disappeared into the clouds.

Kamron was freaking out when Dan came back. "Dude, you look so awesome." "I know right, and apparently I can change my looks by just thinking about it." "How are you able to do this? Was it that weird number or something?" "No" Dan replied. "I think It's time I told you the truth." Kamron sat up with immense interest. "I'm actually from another world." Kamron wasn't shocked at all. "WHICH PLANET?" He asked excitedly. "Mars, Venus, One of Jupiter's moons, a planet we never heard of?" "Hold on." Dan said while moving his hands up and down. "I said world not planted. I'm from the same planet but another universe. It may also interest you to find out that my universe created yours." Dan said with a smug smile. "Yeah...sure." Kamron said. "Next you'll tell me you're actually a 20 year old." Dan raised his eyebrows. "Sit down, this is gonna be a looooooooong story.

In a dark room with very small amounts of light. A nervous Mr. Farns stood in front of a large throne. A metallic voice echoed from the throne. "Are you sure you've found the sixth one?" "I am sir, no doubt about it. Daniel Marsden is the sixth power that you have been seeking." "Good, good. Have him transferred here as soon as possible." "Oh-uh" Mr. Farms began before gulping. "WHAT IS IT?!" The metallic voice boomed back. "There is a slight complication. Small, really nothing to worry about. It's just that he uhm… refused to join the academy." "I see." The metallic voice continued. "It would only make sense. Someone who holds the sixth power wouldn't be persuaded so easily by something like the setup we have here." The voice explained while reaching over and placing a card into a slot. "I suppose it would be best to have the other 5 handle it." A large sea serpent like creature formed in front of Mr. Farns. "Oh no sir!" "I'm sorry to have to do this to you Farns, but as it stands right now, the only function you had will be performed by the others and you simply know too much about us. I'm afraid you are more of an expense than you are an asset. Alright boy" The metal hand raised into the air. "Chow time." The serpent lunged forwards and ate the screaming Mr. Farns in a single bite.

Well that wraps up the first of my fanfictions. Hurray! I know I have changed the effect of number 24 slightly but I wanted the numbers of this world to be more OP, just like the ones in real life. I hope to be able to do more of these soon. Please keep in mind that this is the first time I have written anything in a long time. Feel free to be the grammar police. I will take any criticism and hopefully work it into my next chapters. I hope that next time we can find out just who is this peculiar machine, and where Dan got his odd powers from.

That's all for now. Until next time.
