Nexus HWR 2.5 Arm Wrestling:

"What's going on?" Rin asked as he walked up on the deck of the Thousand Sunny. He walked to the railing in front of the cabin door and looked over it where he heard a commotion on the grass below.

"I believe a bet is going around." Rin snapped his head to the right in surprise as he had asked his question rhetorically. Standing on his right was a tall woman with very large breasts pushing against her tight white top. She had long black hair and smiled down at the group gathered below as well. Robin continued, "Who would you pick?"

Rin looked from Robin back down to the grass. As the people there moved around a little, he became able to see the table Franky was finishing constructing to be extra strong. On either side of the table were other boys on the ship, looking across at each other with competitive looks in their eyes. Closer to the port side was a lanky young man with skinny arms and legs. He was wearing a blue shirt opened down the middle and a pair of red pants rolled up to the knees. He also had a straw hat resting on his back, held there by a string tied around his neck.

Monkey D. Luffy cracked his neck to either side while still looking at his opponent. Behind him, Usopp was rubbing his shoulders and ranting encouragements to him. Gray and Juvia were next to each other behind Luffy as well and Sora stood on their right, pumping a fist up in the air and calling out Luffy's name.

On the other side of the table as the pirate captain was a shorter figure. He had a competitive look just like Luffy, but he also had an appearance of confidence that almost reached the point that he seemed bored. The kid had spiky white hair and did not appear to be worried at all. Killua leaned back on his chair while Dash hopped up and down behind him. Riku had his arms crossed but stood behind Killua as well with Natsu not far from him smirking like an idiot.

Rin looked back and forth between the two opponents as Franky stood up on the side of the table and said that the stage was set. "So," Okumura Rin began, "what are they doing?"

Robin giggled a little from next to the teenager. "Arm wrestling."

"Hey Riku!" Ben called out from on Luffy's side of the grass. He looked behind Killua at his older friend and continued, "Where's your faith in Luffy? Come over here!"

"Sorry Ben, sorry Luffy," Riku apologized to the two of them. He looked at the kid in front of him who glanced over his shoulder a little to look into his eyes. Riku chuckled, "We were supposed to pick the side of who we thought would win."

"Ah come on Riku," Sora called at his best friend. "Luffy's got this one in the bag!"

Goku and Timmy floated above the deck looking down at their friends. Timmy turned to the older man a little, "You know who will win right?" The boy asked the Saiyan warrior.

The man with black spiky hair smiled as he continued to look down. "No, but I have a good idea."

"Alright, are you two ready?" Nami asked the contestants in front of her. Luffy made an affirmative noise and nodded his head once. He slammed his right elbow down on the table with a smack and held up an open fist. He cracked his fingers using just that hand and then left it open with his fingers curled in for Killua to grab.

Killua looked at Luffy's arm, then to his face, then back at the arm. "Not yet," the younger boy stated. Luffy looked confused for a second as Killua still looked mighty confident despite what he said. Luffy opened his mouth to say something, then everyone around them dropped their bottom lips. Luffy's pretty strong, so a little bit of Nen could go a long way. Killua's entire body wrapped in a white translucent aura that flared around him like a blazing fire. "Okay," he said, as his aura gained control around him and steadied with a veil two inches away from his body. "Now I'm ready."

He put his elbow down on the table and looked Luffy in the eyes again. The pirate stared at the kid covered in aura and his confidence was shaken a little. At first he believed it to be an easy win, but now... Luffy's fist turned black and shiny. The Armament Haki wrapped around his right hand down to his elbow and even a little higher up his arm after that.

"Hey Luffy, you sure you don't want to get a little stronger first?" Killua asked as he looked at the pirate's black fist. He grinned and chuckled a little, "I know you're stronger than this."

"No need," Luffy replied, cracking his knuckles again as he held his black hand right in front of Killua's.

Killua shrugged, then his white aura vanished from around him. Everyone looked at him in confusion, but he just smirked and slapped his right hand into Luffy's. His grip was strong and Luffy noticed that even with a coating of Armament Haki he could feel the boy's hand squeezing his. Luffy's eyes began to widen at the exact moment his navigator called out, "Go!"

The table beneath their elbows broke and Franky dropped his metal jaw. He was just bragging about how strong it was to Ben, but now he and the thirteen year old just stared slack-jawed at the broken table in front of them. More precisely they stared at the hole in the floor beneath the table where Killua had slammed Luffy's hand so hard into the ground that the floor broke. The pirate's legs were still straight up in the air since his body was yanked down so fast.

"Ehhhhh?" Half of the ship exclaimed in unison.

Goku smiled down at the floor beneath him. He heard a voice next to him and looked at the boy in a pink hat. "Is that what you expected?" Timmy asked the older man.

"Yep," Goku admitted. "Luffy should have used his Gear Fourth."

"You think that would have made a difference?" Timmy asked.

Goku scratched his chin, wondering if that transformation would really help that much with arm wrestling. The pirate still wouldn't be able to use his rubber powers, but Goku had felt Luffy's strength go much higher before. "Maybe," Goku continued, "but probably not if Killua released more of his aura. I am surprised Killua could power up like that."

Most people on the deck below were thinking the same thing. Even Natsu who had joined Killua's side was staring at the child with a dropped jaw. Only Killua himself and one other were still calm after the pirate got smashed into the floor. Riku chuckled a little under his breath and Killua turned back to him. "What? You aren't surprised?" He questioned.

Riku shrugged slightly, "I had a feeling."

Gray was staring at Killua in awe too. He's stronger than most people on this ship. I never paid much attention to him. He might even be able to tank, though I doubt he would stand a chance against Black Star.

"Heh, didn't see that coming," Kirito said and put his hands behind his head. He glanced at the man next to him who was looking at the younger boy in surprise, "Good thing he's on our side, huh?."

Gray nodded his head dumbly for a second and he turned to the younger man who said it. He looked at Kirito and into the teen's eyes, and his shocked look dropped down to an annoyed one. "Yeah," Gray muttered, but turned away showing that was the end of their conversation.

Kirito watched as Gray walked across the deck to talk to Natsu who seemed surprised by his own pick's victory. The teenager just watched the mage leave and he sighed and mumbled under his breath, "Nice talk."

Fairy Tail Guild Hall

Kirito stood inside the guild hall of Fairy Tail standing ten feet away from a board with lists and pictures pinned on it. There were a dozen people in front of him, and the one in a straw hat ripped a piece of paper off the wall and shouted, "This one!"

"Ah!" Usopp shouted and grabbed the paper from Luffy. "Timmy marked this one down as being 'EXTRA SUPER HARD.' Can't we take an easier base?"

"None of them are going to be easy Usopp," Nightwing told the sniper on his left. "These are all bases full of criminals…" he turned to Luffy and added, "Which makes me agree with him. One that Timmy would label as that hard must be one he considers a job for himself or the Saiyans. Why don't we leave it and go for-"

"It's fine," the group turned and looked up a little to see a boy floating there in midair. The boy was wearing a pink hat and had a pink sheath on his side with a smiling face on it. He was not there a second ago and everyone was surprised to see him. Timmy continued, "We can take that base on. I'll come with you guys."

"Yosh!" Luffy cheered. "Let's go!"

"Wanda," Timmy was getting excited too, and he called out, "I wish we had a super-fast jet to get us to the base quick!"

"You got it Sport," the sheath on his right side replied. Wanda lifted up an arm and her wand lit up golden, and they all heard a thud outside of the hall. The group in front of Kirito turned and ran over to the door and pushed outside to check out their new vehicle.

As the group ran out, a different group was just coming back in, and they had shocked expressions on their faces as a huge plane had just appeared in a puff of smoke in front of them. Natsu, Gray, Juvia, Erza, and Wendy walked into the room and Macao turned his head to look over his booth back at the youngsters. "Back already?"

Wakaba sat across from him and the old man smoking a cigar called out, "What? You forget your coats?"

Erza lifted up her right hand and held up the head of a robot that looked like a gorilla. "It was too easy," she claimed, and the others in the room dropped their jaws as the team had only left an hour before. Erza dropped the steel gorilla head and others started cheering for the team.

Kirito smiled over at them, then turned and stepped closer to the board in front of him where there were less people gathered now. He checked out certain maps that had large areas circled, and found one that did not have an X through it showing it was taken out. Too much area for me to search, even with help. Find a smaller one. He gazed around the map some more, then looked at one of the lists that was labeled 'Slade's Location' at the top. There were arrows pointing from different base designations that correlated with different areas on the map. Guess I could go for another big shot. Akuma and Lelouch in one day was big for these people, they're hoping to get the other leaders soon.

The teen was still checking the map when one of the people who just walked in spotted him. The man with black wavy hair looked over and his eyes opened wide at the sight of the teen. He turned to his friends who were sitting at their booth and said, "I'll be right back."

Gray jogged across the room and the friends he left behind at the table followed where he ran off to. Natsu frowned as he saw Gray's destination and he looked back forward with a more annoyed look. Gray did not see Natsu's expression though, and he ran right up to the teen staring at the board who felt him approach. "Hey," Gray began. Kirito turned his head a little and saw the man looking at him closely. Kirito's eyes opened wider and he turned fully to the man next to him. "It is you," Gray said, and he chuckled a few times. Gray stuck out his hand and said, "Long time no see."

Kirito slowly lifted up his own hand and shook the older man's. "Gray," Kirito said in amazement. "You're here," the teen said, still shocked by this development. "Did Kuma, when he hit you-" Kirito started but got cut off.

"I was sent to Aebrith," Gray interrupted. "Across the world with some others, but you!" Gray exclaimed. "The rest of us all landed in the same area, but we couldn't find you anywhere around. Where did Kuma send you?"

Kirito looked down at the floor and said darkly, "I landed on Awul." He hesitated, and then continued, "When I woke up, my wife was looking down on me. I found her."

"That's right," Gray said, nodding his head a few times. "You were looking for someone back then," Gray said it like he kind of remembered hearing it before, though most everything from that far back was a blur to him. He shook his head and looked at the teen wearing all black in front of him, and he had to scratch his chin as he could not put his finger on it. "I'm sorry," Gray began. Kirito looked at him confused, and Gray continued, "After I got smacked away, I was running for my life for weeks. There were nonstop battles, and I just, I mean," he scratched the side of his head, "I forgot your name," Gray admitted.

Kirito looked at him in surprise for a second, but he shook his head like it was no problem. They only knew each other for close to a week, and back then they were stuck running and hiding from monsters the whole time too; there was not much time to talk. The only reason Kirito remembered his name and not the other way around, was because Gray was one of the ones saving him, while Kirito was just one of the many who needed saving.

"It's fine," the teen began. "It has been a while," he reasoned so Gray would not feel as bad. "My name is Kirito."

Gray stared at the teen in front of him and his smile started to fade. He suddenly realized that the guild hall was oddly quiet and he turned his head. Staring at him was pretty much every person in Fairy Tail, including his friends at his table. Natsu just told Wendy and Juvia who did not know why Natsu looked so annoyed, and the girls had uncomfortable expressions on their faces as well. Most people were looking at him funny, though a few were glaring at the kid past him harder, like he was an enemy. "Kirito," Gray muttered, and he slowly turned back to the teen whose expression was dark as he realized Gray had heard that name before. "You, are the Underworld member?" Gray asked, his voice full of disbelief.

Kirito stayed quiet for a second but he could not longer keep eye contact with Gray. "I, was," Kirito said, emphasizing the past tense. "I didn't know, I-" he looked up to Gray's face to give him an explanation, but the older man did not look like he wanted one. Gray took a step back and the look of disgust on his face was impossible to mask. "I, I'm sorry," Kirito whispered.

"You people killed Master Makarov," Gray snarled, keeping his voice as a hiss so that only Kirito would hear him. "He raised me like a son, and you people poisoned him," Gray had to spit the word 'people' out as it tasted bad on his tongue.

"I didn't know about any of that," Kirito whispered, but his head was bowed and he said it to the floor. "I just, needed somewhere I could train. I thought the Underworld was the only option I had."

"Fuck off," Gray muttered. He walked towards Kirito and bumped him purposely with his shoulder as he walked to the board. Gray grabbed the first flier he saw and ripped it off before turning around. "Only option my ass. You're just coming up with excuses because you know you're trash. I didn't remember your name," Gray said, stopping as he walked by Kirito, and speaking away from him still in a voice so quiet only they could hear. "But I remembered you were a good kid. The way you looked after that girl, the one with wings. You were good. I remembered that."

Gray walked away and Kirito clenched his fists at his side as he stared straight down at the floor. Angel. If only you knew Gray. If only you knew how the Underworld had brainwashed her, enslaved her, Kirito was shaking in his boots and he could not help the shame from filling him. He turned back to the board and heard someone call to him from the doorway. "Oh hey Kirito, you going out to fight an Underworld base?"

Kirito heard the voice and he reached forward, grabbing the highest level flier in front of him. "Yeah," Kirito said. He turned and saw Goku standing in the entrance. Some Fairy Tail mages stopped giving him as harsh gazes now that the Mayor was there, considering Goku vouched to everyone for him and they all trusted him. Kirito held up the paper in his hand and said in a dark voice, "Let's go destroy them." His expression was determined and scary, and some of the mages who were looking at him angrily a minute ago suddenly felt worse for the monsters he was going after. I will make this right, Kirito thought, I need to.

Present

Thousand Sunny

A fourteen year old standing on the grass of the Thousand Sunny's main deck watched as Gray marched away angrily. The man with wavy black hair heard a conversation on his left and saw Sanji and Natsu arguing with each other. The excitement from the arm wrestling was dying down, and Killua turned his attention to them and listened in to what caught Gray's attention. Franky and Usopp were listening in as well as Sanji snapped, "I thought you said the Black Witch."

The chef looked the Gray as he said it and Gray nodded his head. Natsu turned to his friend annoyed now and he said, "Wait, you said Zeref was there. He's the Black Wizard, right?"

"Listen," Gray said, annoyed he had to repeat himself here. "The black wizard Zeref goes by the title, High Lord Spriggan. The witch, Arachne, actually goes by the title Black Witch." Sanji smirked at Natsu who frowned that he was wrong. Gray continued to the group in front of him, "Arachne was the member of the Co-op who moved farthest south into Resistance territory back when I was there. No one could stop her and she took over most of the eastern coast of southern Aebrith."

"Couldn't you guys go all out and fight her?" Usopp asked.

"There were a few large invasions," Gray said, though he grimaced as he did. "Everyone who made it back from those attacks have bad memories of it. The witch has under her control a monster, a Kishin. Whenever we try to attack her, the Kishin's madness takes over. Friends kill each other because they think their friends look like their enemies. Snakes crawl out of your skin and spiders out of your eyes," Gray's eyes were distant and he had some sweat on his forehead. After a few seconds' pause he shook his head and looked at the four in front of him who realized he was one of those people he mentioned who still had nightmares about those attacks. "Let's try to stay away from both the black wizard and the Black Witch, alright?"

"Got it!" Usopp shouted instantly.

Gray nodded and kept walking away, and Killua turned away from their conversation and walked the other way with his hands in his pockets. Kishin's madness, that's a new one. Killua did not like the idea of an enemy he could not reach without getting past such a crazy monster. How could I even fight something like that?

The idea that he could not stuck in his head and it aggravated him. Time for some training then, he thought, and looked up at a room above the ship he could use for just that.

Killua climbed up the mast of the Sunny and walked over to the door of the weight room. He stepped inside and looked around but did not see anyone else in there. A second after he relaxed though, he tensed up and his eyes darted to the ceiling.

The white haired kid calmed down again as the presence he noticed was just a man in an orange gi flying around, punching and kicking in front of him for practice. Goku finished his set and flew down to the ground where he picked up a white towel and used it to wipe some sweat from his forehead. "Whew, it sure is hot today, right Kil?" Goku asked, turning his head and glancing over at the door.

The fourteen year old nodded at Goku and he walked farther into the room. "Mind if I train in here too?" Killua asked him.

Goku shook his head 'no,' but then he got a better idea and asked excitedly, "Want to spar?"

"With you?" Killua repeated, wondering if he heard right. He held his hands up in front of him, "I don't know what you think of me, but I'm not being modest when I say I wouldn't stand a chance."

"Oh don't say that!" Goku exclaimed. He ran up closer to Killua and bent down with his hands together in front of him in a begging position. "I know you're strong, but I want to see what you can really do."

Goku sounded like an excited kid about to get candy and Killua felt bad that he was not giving it to him. The boy sighed, conceding, and Goku cheered happily before jumping backwards and doing ten back flips on his way down. Goku landed and got right in a fighting stance, one that Killua could not see a single hole in and made the boy nervous though he tried not to show it.

I thought he was just incredibly strong, but that stance, I've never seen anything like it. I don't even know which direction to attack from. His whole body is guarded, I'll need to attack left first to draw his right hand in for a block, then try to get around, Killua got lost in thought just from Goku putting his hands up, and the Saiyan warrior could not be more excited when he saw the gears working in Killua's head.

He's fast, maybe as fast as I am in my base form. Stay in it as long as I can, but maybe Kil can make me raise to the next level! I hope he does! Goku's thoughts were less focused than Killua's, but his posture did not take a toll from it. "Ooh," Goku uttered as Killua started walking right. He was surprised because Kil left after-images of himself behind as he made a circle around Goku.

He looks like a master martial artist, this won't trick him for long. I don't want to show him everything too soon though. Maybe start with just some hand to hand combat, Killua decided and he rushed forward from the spot on the circle of Killuas directly behind Goku. Goku was not tricked by the technique though as he felt Killua approaching behind him.

Even at a fraction of his maximum speed, Killua was still amazingly fast. He rushed at Goku hoping to catch the Saiyan off guard, but as he punched towards Goku's back, the man's left arm was curling back and he caught Killua's left fist with an open palm. Goku curled his fingers on that palm and held Killua's hand tight, but Killua pressed his other hand down on the ground and he brought both of his legs around in a kick on Goku's left side.

He thought he could hit Goku's arm and get him to drop his hand, but Goku crossed his right hand over his chest and stopped Killua's left leg only. Before Killua's right leg collided with Goku's left arm, Goku pushed Killua's right backwards and changed the boy's momentum entirely. The younger fighter did not expect the force put into that small push, and he was thrown away from Goku who let go of Killua's left fist to allow him to fly across the room.

Killua flipped himself in the air and skid back on two feet when he landed. He skid twenty feet so he was almost at the wall, then snapped his head back up to see Goku looking over his left shoulder at him. The spiky haired Saiyan pointed down at his feet and Killua looked down before opening his eyes wide and grinding his teeth. "Gonna have to try harder than that if you want me to move," Goku teased over as his feet were still planted in the same spot facing the entrance of the training room.

"Alright," Killua muttered. His head bowed for a second and a dark shadow came over him. Goku's eyebrows lifted as an aura of a snake surrounded Killua and he snapped his gaze up to look into Goku's eyes. His own irises were vertical slits now and Killua picked up his speed.

Toy with me again, Killua thought as he sprinted the edges of the room. As he ran, he picked up various sizes of dumbbells from around the room. As soon as he picked them up he measured how much strength he would need considering their weight, the distance, and his intended target, and he would throw the weights at Goku who spun around his head in amusement much faster than the weights were approaching to see what was happening. The black haired man rose up his hands and caught weight after weight and dropping them to the floor just as fast. Killua kept running though and he threw a few more weights before sprinting forward himself.

Goku was waiting for this, and with the dumbbell he just caught in his right hand, he flicked it at Killua whose eyes widened at the weight flying at him twice as fast as he threw it. A spark of lightning surrounded his arms for a millisecond and his arms snapped up so he could catch the weight. Goku looked amused but he kept moving his arms to catch the other weights still coming at him. Killua was getting pushed back by the force of the weight that hit his hands, and he winced in pain as his arms were shaking from the momentum of it.

Killua flipped over the weight and let it fly past him into the wall. The boy himself then leapt back onto the wall where he crouched his legs and sprang off at a hundred miles per hour. He flew across the small room and caught a weight that he threw before and had intentionally missed Goku with. Goku was currently focusing on three different weights coming at him at the same time, and he dropped the two in his hands to make room for them, but his eyes still had the time to dart over and watch what Killua was doing.

Killua saw him look and he mentally frowned but continued his strategy anyway and threw the weight forward. Goku saw it was aimed at his stomach and he leaned his body to the side so as to keep his feet planted as was the first goal he set for himself when challenging Killua to a sparring match. He moved just enough that the weight would miss him, and at the same time caught two of the weights flying at him. The third from before was coming for the point between his eyes, and he leaned his head back to duck under it. As he ducked though, he heard a loud clank directly in front of where his stomach just was.

Goku wanted to lean back up fast to see what was happening, but the third weight was still passing over his face and to lean up he would get hit by it. He hesitated and then lost his balance as the floor beneath him cracked. When he leaned up he saw a weight lifting up in the air slowly in front of him, the same one Killua threw last. His eyes went down and he saw one of the two weights he had dropped in the previous second was still falling, but the other got hit by Killua's throw and sent smashing into the ground at a much higher speed that the floor cracked and Goku's feet lost balance. He lifted back up his gaze to tell Killua how great of a move it was, but his eyes opened huge at the sight of the kid only a few feet in front of him.

Killua's nails were sharpened and his eyes were still vertical slits. He slammed his right hand forward towards Goku's chest, and his nails cut through Goku's orange gi. Killua's victorious smirk vanished from his face though, and an expression of pain appeared instead. He yelled out as he stared at his right wrist that Goku's hand was clenched around. Surrounding Goku's hand was a golden aura, an aura that stretched up his arm and covered his entire body, made his hair golden as well, and his eyes an icy teal.

Killua suddenly felt very, very afraid as Goku looked down into his eyes. He realized that he really did not know Goku that well, and he was a second from killing him right there. He opened his mouth to apologize, but Goku's flat lips curled up into a big grin first. "That was great!" Goku told him, and he let go of Killua's hand. He stayed as a Super Saiyan and laughed a few times as Killua backed off. "For a second there, I thought I was gonna die! Hahaha," Goku leaned back and laughed more heartily.

Killua looked at the man like he was insane, but the next sentence caught him even more off guard. "You're a very good fighter Killua," Goku began. "Let's keep going. Next time I'm going to get serious, so try to keep up."

Killua's shocked look slowly changed and he himself started laughing. He rose up his hands and his nails stayed extended. If Son Goku was fine with training like this, who was he to argue? I'm fighting a Super Saiyan! Killua thought in exhilaration. Killua shot forward, but Goku moved this time and appeared on his left side, moving so fast it looked like Killua was moving in slow motion as the kid turned his head in awe to look at him. "Going to have to pick up the pace," Goku said, before spinning a kick into Killua's side and sending the boy flying.

Killua's strange thrilled feeling to be fighting a Super Saiyan vanished and an empty, forgetful feeling replaced it. What the- That's one Hell of a power up. Killua leaned up but Goku was flying across the room towards him and he dropped his bottom lip. He jumped up high and Goku changed his trajectory to chase him. He bounced off the ceiling and the walls crazy fast to try and keep his location hidden, but Goku's eyes darted around and he followed the boy every step of the way.

Killua sparred with Goku for longer than he realized. The Saiyan matched his speed at all times but would only surpass him when Killua got close to landing a hit. The boy retracted his nails after a little as it did not make sense to keep them out when Goku kept dodging, but as soon as the nails were back to normal he started landing hits. Goku stopped speeding up and if Killua got a good move in on him, Goku would take the blow but strike back instantly. He reverted from his Super Saiyan state after only a little of their training and Killua was trying hard to force him back into it.

Killua put immense amounts of power into his punches, but Goku took each one in stride. Killua bounced off the ceiling coming down for Goku's head and he shot a burst of lightning first at the Saiyan's head. He learned Goku's eyes could process fast enough that he had already seen the few times he used lightning in their fight, so he stopped trying to hide it and zapped the Saiyan instead. He brought back a fist, but Goku kept looking up, not flinching from the lightning that zapped him. What?! Killua thought as he saw Goku's smirk.

He punched down but Goku saw it was a feint and rose his other arm to block Killua's foot. He grabbed the boy's left foot above the laces and he lightly pushed it the other way, then tapped the other foot with his same hand as it spun around the first. Killua's first punch turned into his main attack and he yelled out as he focused more of his strength into it. Goku rose up his right hand and caught Killua's hand, but his and Killua's eyes widened as the floor beneath Goku creaked and the Saiyan's legs bent down.

Goku was back in his base state but neither of them expected the amount of force that just went into that punch. Goku rose his other hand to stop Killua, but as he rose it his legs came out from under him. Killua's eyes widened and he pushed down harder to finish the punch, but his arm moved the wrong way as he wanted it to and he got flung back up into the ceiling. "Ah! What's happening?!" Killua struggled around and then heard laughter coming from the doorway.

Goku caught himself with one hand before he hit the ground, and he pushed off that hand and kicked his legs up in the air. He arced up and landed facing the doorway with a smile on his face. "Hey Timmy," Goku greeted, and an invisible boy in the entrance appeared in front of him. Goku seemed surprised, "That's weird, I couldn't feel your energy."

Timmy smirked and he rubbed his nose with his index finger. "I was in stealth mode," he said, though Goku did not really get what that meant. Timmy explained, "Can't see me, can't hear my footsteps or breathing, can't feel the vibrations I make with every step, and..." He held up a finger for every power he stated and this was the fifth one so he had a full hand raised. "I don't give off any energy at all."

"Nice," Goku said, though he was already thinking up ways he could find Timmy while he was using that stealth mode. "Want to spar with us?"

"Yeah, and want to let me down?" Killua called over from the ceiling. The other two looked up at the annoyed boy crossing his arms and glaring at Timmy.

Timmy chuckled a couple times nervously then lowered the older boy down with his mind. "Sorry," the kid who messed with him said as Killua touched down in front of them. The older boy only glared for a second before sighing and slouching his shoulders.

"So Timmy," Goku began. "Want to join us?"

"It's why I came up here," Timmy replied and he smiled softly at the older man.

Killua got some sweat on his forehead. When I asked the Straw Hats if I could come with them, I did not expect to be sparring with Son Goku and Timmy Turner. This could, get ugly, Killua took a step back and he waved a hand at them. "I'm actually feeling a little tired. I'll just watch for now."

"You sure?" Goku asked, as he had been having a fun time fighting with the white haired kid. Killua repeated himself and walked over to the side of the room where he took a seat on a bench. "Alright then," Goku said, and he spun to Timmy with a big grin. "You ready?" Goku asked, curling his fingers in and cracking his knuckles in front of him.

"Let's do it," Timmy replied. He turned his body sideways and closed his eyes. When they snapped open, they were narrowed and his eyebrows dipped in. His eyes had yellow irises with black horizontal lines through them, and under his eyes his skin tinted green. Timmy rose up his fists too and Killua was again surprised to see a stance better than his own.

Timmy and Goku flew off the floor and they shot towards each other. Killua's eyes widened and his eyes darted around the room as the two of them flew around. Timmy got a white aura around himself but Goku followed suit. The two of them were still visible to Killua, but their movements at this speed were too fluid, too thoughtless. They are not thinking as they fight. Sure, they're imagining moves, but those are moves ten moves from now, Killua thought in amazement. Everything they do is natural, no thoughts needed. All instinct. At such speeds too.

The two fighters stopped across the room from each other and they lowered to the floor. "Something wrong?" Goku asked as his young opponent was taking very deep breaths like they had been fighting for a while.

"No," Timmy replied, though his voice was dark. He curled his elbows in to his sides and clenched his fists hard. The training room around then started to shake as Timmy's aura grew bigger. "Let's take it up," Timmy began. "A notch!" He roared, and a huge gust of wind slammed into Killua.

Goku opened his coal black eyes in surprise as Timmy's skin started to ripple. "Are you sure about this?" Goku yelled over the wind.

The crew on the Thousand Sunny below looked up as the sky above the crow's nest started distorting. The blue sky changed color and got a lot darker. Wind rushed around then and their ship was trembling on the ocean.

"I'm sure," Timmy yelled back at Goku. He yelled again a second later, but he was not making out words, just screaming in pain. His arms and legs extended, his muscles bulking out as they did. Killua's jaw dropped in recognition and his whole body covered in sweat as Timmy's face became more defined, his brown hair got longer and fell back behind his head, and his chest buffed out in front of him stretching his pink shirt that oddly had the ability to match his new size.

Timmy was now taller than Goku, with muscles as large if not bigger, and his aura was a hundred times more intense. "Form 3!" Timmy yelled. The kid started panting over and over and his breaths sounded like he was wheezing.

"That sounded intense," Killua said, still hearing Timmy's pained screams in his ears. "Is it always that painful?" He asked.

"It is now," Timmy replied in a dark tone. Goku frowned and Killua looked back and forth between them in confusion. Timmy looked into Goku's eyes, "With Wanda gone, I need to be able to transform on my own. If I don't get used to it now, when I really need it on Aebrith, I won't be able to transform in time."

Goku nodded at him as that made a lot of sense. Killua on the other hand, just thought, Who the Hell is Wanda, and how would she make transforming easier?

"You ready?" Timmy asked, his voice still high-pitched despite his eight foot tall body. Goku nodded back and the Saiyan's spiky black hair all shot up in a single spike that turned golden.

Now I get to see these two fight seriously, Killua thought, only to drop his jaw as they vanished from in front of him. He calmed down and his eyes darted around following blurs as they smashed into each other and bounced back. An explosion blew up in the air up to his left, but when he looked over he heard the slap of a fist on skin to his right.

I need to follow their movements... No! Don't waste Godspeed just to watch a fight. No matter how much you want to watch it, Killua kept looking around and he would catch glimpses of the fight going on around him. The longer he watched, the more his eyes adjusted to the speed the other two were moving at which made it easier to enjoy their spar.

After ten minutes of the two fighting, they took a break and Killua could fully evaluate the damage on them. It was not hard to see who had been winning the fight, as Timmy had a trail of blood coming down from the right corner of his lip, and a lot more bruises in general around his body. Goku did not come out without his fair share of damage though, scratches on his arms and legs and a bruise on his left cheek. Goku though, was not panting like his opponent at all.

"Want to hop back in this?" Goku asked, turning to look over at the bench Killua was sitting on.

The boy held up his hands, "I'm good," Killua replied. He tried looking confident as he hopped off the bench and started walking towards the door. "Maybe some other time," he said.

"Aww," Goku complained. "I wanted to see what you can really do," he groaned. Killua stopped where he was and darted his eyes over to see Goku smirking at him. The Saiyan knew he was holding back some moves, and Killua chuckled for a few seconds when he turned back to the door.

As he re-faced the door, his eyes opened wide and he took a step back. The ground in the entrance lost its brown wooden color, turning instead to a pitch black. The feeling of the darkness made Timmy and Goku both look over as well. Unlike Killua though, the two of them just grinned at the dark circle and at the oval of black that shot up out of it. Dark wisps swirled around the portal that had a center of deep purple.

Killua looked into the portal and saw a dark shape approaching. The teen stepped out of the portal with his arms crossed, looking into the room amusedly. "You know you guys are shaking the whole ship, right?"

"Hehe," Goku laughed and scratched the back of his head. "Sorry about that."

"Oh I don't mind," Riku said. "Nami told me to come up here and scold you guys, but I've got a better idea." He held up his hands and two flashes of light appeared in front of him. He clenched around the light, and black and red hilts formed in his grasps. "Mind if I join in?"

"Sure," Goku exclaimed happily.

"You can take my spot," Killua said, and he kept walking towards the door now that the black portal vanished. Riku was wearing a yellow tank top and blue jeans that were ripped up around the knees. Killua was annoyed at himself for being nervous upon seeing the darkness in the first place. The Straw Hats I could handle, Killua thought as he walked by Riku. But there are too many monsters on this ship.

He walked into the doorway as Riku walked farther inside. Goku and Timmy let their auras fade and it looked like they were going to revert to weaker states. "Don't on my account," Riku began, making the other two look at him in surprise. "I can keep up," the teen said, and he held his arms out to the sides.

Killua heard Riku speak and he chuckled darkly under his breath. He has no idea what he's talking about. Those two are- He glanced back and his jaw dropped. Riku lifted off the ground with his arms raised, and his entire body covered in a bright white aura that stayed there while his clothes underneath shifted to become much darker. His skin got wrapped in a dark coating of, of darkness that pulled tight against his muscles and made them look bigger. Timmy and Goku both grinned and they regained their auras.

The battle started and Killua could barely follow the movements of the two bigger fighters. Riku was trying to keep up, but it looked like his boast really was just that. Riku got punched by Timmy and then kicked by Goku so that he flew back across the room into the wall.

Timmy smirked over and he called out, "Sure you don't want us to slow down?" Goku went in for a punch but Timmy saw it and lifted a block, only for an elbow to slam into his left temple instead and send him flying.

Timmy flipped in midair to control himself and he focused only on Goku again. The Saiyan was distracted like he was a second ago and he prepared to attack, but he realized that Goku would not do something like that for no reason unlike him. He risked a dart of his eyes towards Riku, and his eyes opened wide as the floor around Riku was dropping into darkness. The darkness spread from Riku to the walls and surrounded the entire room in a few seconds.

Killua stepped back from the doorway so he was closer to the railing. He looked at the room in front of him that turned into a realm of darkness. Out of the walls, floor, and ceiling, creatures of the darkness emerged. Killua gulped at their beady white eyes and powerful bodies as they appeared all around Goku and Timmy. He heard yelling down below him and noticed that even the outer walls of the training room were starting to turn black.

Killua turned and hopped off the crow's nest as the fighting started back up behind him. He hit the grass deck below and wiped some blood from below his nostrils. The others all looked at him and Nami snapped, "What is Riku doing? He was supposed to stop them!"

"He joined in," Killua replied as he walked by her. He tried to hide it but the others noticed a small limp in his left leg. An explosion sounded above them and everyone looked up to see a ball of darkness flying out of the right side of the crow's nest. The darkness faded to show light inside it like someone else hit the wall with a beam, and wooden shards fell out of the air around the light and dark as the fight above damaged the ship.

The pirates and their comrades talked about the fight above and some of them talked about joining in, but Nami yelled at them that they don't want to have to stop to get more materials again. This got Gray to agree with her and argue about going faster to Aebrith and taking less stops.

Killua walked away from them though and towards the cabin. The ground beneath his feet shook and he glanced back up at the training room shrouded in darkness. Keep making friends with them. With their power, I won't have to worry about anyone.

He smirked as he reached the cabin door and grabbed the handle. He froze as he held onto it though, Just remember, if they knew, they would kill you in a second. Goku, Timmy, Riku, they would all turn on you. He opened the door and stepped inside, closing the door behind him and leaning back on it. They can never know my secret.
