Chapter 5: "Let's Get Beat Up Together!"
(In which Naruto offers himself to be hero-punched by half the roster, and somehow makes it sound like a team-building exercise.)
Naruto awoke with something very rare in the ninja world: a peaceful morning.
The sun poured through the sleek glass windows of Mount Justice like golden syrup, pooling over the floor and warming his face as if even the sun was like, "You did great, kid. Sleep in."
He stretched luxuriously, back popping, limbs limber, chakra pulsing through his body like a perfectly tuned engine. For the first time since arriving in this dimension of tech geniuses and caped weirdos, he didn't feel like a lost tourist.
He felt strong.
He felt rested.
He felt… not alone.
"Man," Naruto murmured, flopping back against the bed, "having Kurama around full-time feels good."
"About time you noticed," Kurama grumbled in his head, sounding vaguely insulted.
But Naruto just grinned. Because yeah, he had a partner now. A piece of home. And for the first time in forever, he didn't wake up with that hollow ache in his chest—the one that whispered you're alone every morning since he was a kid.
He was not alone.
Throwing on his orange and black gear (because fashion never dies), Naruto stepped out into the sleek metallic common area of Mount Justice—and immediately noticed something different.
The team was assembled.
And not just chilling. They were focused, alert, circled around Nightwing like students around a really good-looking substitute teacher.
Nightwing looked up from his holographic mission screen. "Morning, Naruto. Hope you slept well."
Naruto gave a thumbs-up so cheerful it could've jump-started a car. "Like a log! I'm pumped for our sparring match today! Also… do you guys have ramen? Or do I have to summon it from the Shadow Realm?"
A few chuckles rippled through the room.
"Ramen can be arranged," Nightwing replied with a half-smile.
"Thank immortal," Naruto exclaimed—and then, like the chaos goblin he was, launched himself forward and hugged Nightwing like he was reuniting with an old war buddy.
Which would've been fine… if Naruto hadn't forgotten he was now built like a golden demigod fueled by solar steroids and ancient fox chakra.
"Gah—Naruto—ribs! RIBS!" Nightwing gasped, sounding like someone getting squeezed out of a toothpaste tube.
Naruto instantly dropped him like a hot potato, hands up. "Oops! Sorry, sorry—I swear I didn't mean to nearly crush you! That was my 'happy-to-have-breakfast' hug!"
Nightwing took a moment to realign his internal organs before managing a strained chuckle. "No worries. Just… maybe stick to high fives for now?"
Once the room stopped laughing at the accidental near-homicide, Nightwing shifted back to business mode.
"So, about that spar—you sure you want to fight me? You could go against Conner. He's the strongest physically. Or maybe test your speed against Kid Flash."
Naruto shook his head, eyes sparkling with that familiar blend of optimism and mild insanity. "Nah, I wanna fight you. Different types of fights teach different things. And besides, back home, sparring with your friends is how we grew stronger. We tested each other, adapted, pushed ourselves to the next level."
M'gann looked surprised. "You mean, you fought your own team?"
"All the time!" Naruto grinned. "Kakashi-sensei even made us fight bells. You'd think that sounds easy. It's not."
Robin smirked. "You sound pretty confident. You sure you're ready for what Nightwing can do?"
Naruto met his gaze with the kind of look that said I fought a giant fox once and walked away. "Trust me. I'm ready."
Nightwing chuckled. "Alright then. Match starts at 12:30. Until then, kitchen's that way. Let's get you some ramen before you suplex someone else by accident."
Naruto's grin grew impossibly wider.
--------------------------
As Naruto and Nightwing strolled through the sleek corridors of Mount Justice, the conversation shifted—naturally—from food to fighting. A logical progression when one of you is a ninja and the other is an ex-Robin.
Naruto gave the older hero a curious side-eye. "So… how do you usually fight? No offense or anything, but you're not exactly bursting with laser vision or muscles that punch planets."
Nightwing smirked, unfazed. "That's true. But I don't need powers to win a fight. Strategy, experience, technique—those go a long way. I've taken down people twice my size by thinking five steps ahead."
Naruto's grin widened. "Ohhh, that makes this even better. Let's see if your strategy can handle my unpredictability. I mean, my battle plan is basically 'wing it until something explodes.'"
Nightwing raised an eyebrow, amused. "That explains a lot."
"Hey! Controlled chaos is still a strategy."
Nightwing chuckled. "Only if you live through it."
They turned into the kitchen, which was more like a sleek sci-fi café than anything Naruto had ever seen. There were smoothie stations, high-tech ovens, and even a glowing touchscreen ramen generator. Okay, it was just a regular microwave, but Naruto was convinced it had the soul of a chef trapped inside.
As they entered, a sudden flash of orange and green energy zipped past them. Starfire, glowing with her usual sunny radiance, zoomed into the room and immediately wrapped Nightwing in a warm hug.
"Greetings, beloved!" she said cheerfully, giving him a quick kiss on the cheek. "I sensed your energy signature and wanted to say hello before you begin the glorious combat of friendly intention!"
Naruto blinked. "Combat of what now?"
Nightwing coughed. "She means sparring."
"Ohhh. Yeah, that checks out."
Then Starfire turned to Naruto and tilted her head. "You have very curious energy. You remind me of Beast Boy… and also myself. It is the chaotic brightness. It sings."
Naruto's jaw dropped slightly. "Wait—what?"
"You are like if Beast Boy and I had a spark child," she added with a bright, genuine smile, as if she hadn't just made the wildest comparison Naruto had ever heard.
Nightwing choked on absolutely nothing and gave her a look. "Kori…"
"What? He is bright and strange and exploding with joy and danger. It is a compliment!"
Naruto gave two thumbs up. "Honestly, I'm not even mad. I've been called worse. Also—'spark child'? Kinda cool."
They made their way to the counter where Naruto was finally handed a steaming bowl of heaven—ramen, blessed be.
Naruto clasped his hands together reverently. "Thank you for this gift, ramen lords."
"Do you always talk to your food?" Nightwing asked as he leaned back with a protein shake.
Naruto didn't break eye contact with the bowl. "Only when I'm about to go to war."
Starfire floated beside him, watching with wide, fascinated eyes as Naruto inhaled the noodles like a vacuum with ninja reflexes.
"I believe he is ascending," she whispered.
Nightwing sipped his shake. "He's definitely something."
--------------------------
The sun was high in the sky, casting golden rays across the lush island that surrounded Mount Justice. The waves lapped against the shoreline in a gentle rhythm, almost mocking how peaceful the world was before Naruto Uzumaki decided to drop an explosive idea in front of a dozen super-powered teenagers.
Naruto strolled beside Nightwing across the grassy clearing, hands behind his head, soaking in the breeze. His stomach was full of ramen, his chakra was buzzing, and his mood? Absolutely ready to be punched into the stratosphere by new friends.
When they rounded the building and reached the wide-open training field that spilled into the beach, Naruto's blue eyes scanned the group ahead.
A small crowd of heroes—some lounging, some sparring, some just enjoying the sun—turned their heads as the two newcomers approached.
Nightwing raised a hand in greeting. "Team, meet Naruto Uzumaki. He's… not from around here."
"Understatement of the century," Naruto muttered under his breath.
Standing (or floating) around were Beast Boy, who was mid-transition from a toucan into a teenager with mossy green skin, Superboy, arms crossed like a living wall of brooding muscle, and Blue Beetle, his alien armor glinting in the sun. Beside them stood Robin (Tim Drake), sharp-eyed and silent, and Lagoon Boy, who was suspiciously eyeballing Naruto like a territorial sea creature. Static, meanwhile, gave a casual nod, sparks crackling from his fingertips.
Chilling by the water were the girls he had met earlier—Wonder Girl, Batgirl, Bumblebee, Miss Martian, and Starfire, who waved cheerfully.
Naruto returned the wave, grinning. "Hey everyone! Great weather, huh? I hope you're not too tired… because I'd like to fight all of you."
A beat of silence.
"…What?" Robin asked flatly.
Nightwing, arms folded now, replied casually, "Naruto wants to spar the team."
Beast Boy blinked. "Like… the whole team?"
"Yep," Naruto confirmed with a bright thumbs-up. "All of you, all at once."
Superboy raised a brow. "That's… ambitious."
"Or suicidal," Blue Beetle muttered under his breath.
Wonder Girl frowned. "Are you sure you know what you're asking for? We don't exactly hold back when we train."
Naruto chuckled, not even a hint of worry on his face. "It's fine! I can make hundreds of clones. So even if all of you come at me at once, I've got the numbers advantage."
"Clones?" Robin asked, still unconvinced.
"He means shadow clones," Nightwing supplied. "Each one has solid mass, can think independently, and disperse when hit."
Superboy crossed his arms tighter, frown deepening. "Still sounds arrogant to me."
Wonder Girl nodded. "You're basically asking us to dogpile you. That's not sparring—that's a beatdown."
Naruto laughed. "Exactly! And I'm fine with that. I'm not some sore loser. You can all knock me around like a practice dummy if you want. I'll just get stronger from it."
That got a few raised eyebrows.
"I'm used to it," he added with a grin. "Back home, half my friends used to punch me during training. I was like their favorite punching bag with a smile."
Beast Boy scratched his head. "I mean… if he's volunteering…"
"Besides," Naruto said, "what better way to learn each other's fighting styles than to experience them head-on? Win or lose, I'm not gonna cry about it."
Nightwing didn't interrupt. He was watching closely, letting the situation unfold. Naruto reminded him of another brash, sunny-haired boy he'd once known—someone who ran headfirst into chaos, not because he thought he was invincible, but because he had something to prove.
Miss Martian floated closer, her expression soft. "You're really okay with this?"
Naruto nodded. "If I collapse, someone can just drag me back inside and dump a bottle of water on my face. Easy."
Lagoon Boy chuckled. "You're insane."
"Just passionate," Naruto replied. "Insane comes later."
Naruto stood tall, kunai in hand and mischief in his eyes, like a kid who just challenged a chess club to dodgeball.
"Let's play a game," he said, flipping the broken kunai between his fingers. "Simple rules. You guys pick a target—someone holds this batarang. I'll keep this kunai. If I steal yours before you steal mine, I win. If one of you gets this from me… well, feel free to rub it in."
There was a beat of silence.
"…That's either the most fun idea I've ever heard," Beast Boy said, "or the most infuriating."
Blue Beetle tilted his head. "So… like ninja hide-and-seek?"
"Exactly," Naruto beamed. "But with the added bonus of explosions."
Nightwing crossed his arms thoughtfully. "Alright, fair rules. But we're making this a challenge. You keep the kunai on your person—no clones hiding it in another dimension, or whatever your ninja magic allows. In return, we'll use this batarang." He held up a standard-issue black, wing-shaped gadget. "And it stays on whoever we choose—no passing it around mid-game."
Naruto grinned, already loving the setup. "Deal."
"I'll signal the start with an explosion," Nightwing added. "You'll know it when you hear it."
With a final nod, Naruto vanished into the forest in a flicker of orange, wind whipping behind him. Somewhere between "this is going to be fun" and "I hope I don't get vaporized," he darted between trees like a blur of sunlight.
Back at the beach, the team gathered into a loose huddle.
Superboy crossed his arms with the intensity of a guy who didn't understand board games and was pretty sure he hated them. "You seriously think he can pull this off? Come on. He doesn't even know who has the batarang."
Nightwing kept his tone neutral. "That's the point. He's testing us as much as we're testing him. This isn't about winning—this is about figuring out where he fits on the team."
"Exactly," Batgirl said, "and Conner, I'd really appreciate it if you didn't Hulk-smash our guest until he tries something actually worth smashing."
Lagoon Boy snorted. "I say let him try. I'll bubble-wrap the batarang before he gets anywhere near it."
Wonder Girl gave him a dry look. "Yeah, because you're the one we'd trust to protect the most important item."
Robin (Tim) adjusted his gloves, completely ignoring the banter. "So who's carrying the payload?"
Nightwing turned to Miss Martian. "M'gann. You're our best bet. Stay invisible, airborne if possible. Don't attack unless necessary. Let him come to you."
Miss Martian nodded. "Understood."
The team huddled in a tight circle like the world's most athletic breakfast club.
Years ago, this moment would've been chaos—Superboy charging in first, Beast Boy cracking jokes mid-battle, Lagoon Boy doing literally the opposite of what he was told. But now? Now they waited.
Because Nightwing was the boss. And even if he looked like the cool older brother who always knew where the pizza was, everyone on that beach had learned not to underestimate him. Especially Lagoon Boy—who once ended up inside a frozen bubble trap for three hours because he didn't follow orders.
So when Nightwing asked, "How do we kick ass?"—they listened.
He glanced at the holographic scanner in his hand, fingers dancing across the controls.
"…He's gone."
A silence fell over the group.
"What do you mean gone?" Robin asked, leaning in.
"I mean," Nightwing said, tapping the screen, "no trace. He vanished right off the radar. Stealth level: spooky."
Meghan—Miss Martian—closed her eyes and reached out with her mind. A moment passed, and her eyes snapped open. "He's near the far cliffs. Just above the ocean. His mind is… sharp. Focused. Excited."
"So he's waiting for us," Superboy said, cracking his knuckles.
Nightwing smirked. "Then let's not disappoint him."
He pointed at Superboy. "You and Starfire approach directly—test his reaction time. Force him into the open."
Starfire's eyes lit up—literally. "It will be a glorious battle."
"Bumblebee," Nightwing continued, turning to the tech-savvy hero, "hover behind them. Use your vibration wings. If he tries to throw anything, shred it in the air."
Bumblebee gave a firm nod. "Roger that. No ninja tricks getting past me."
"Lagoon Boy," Nightwing said, pausing for just the tiniest second (possibly for dramatic effect… or caution), "head into the water. Give us control of the ocean. Try to trap him with water pressure if he gets too close to the cliffside."
Lagoon Boy cracked his knuckles. "Finally. Something I'm good at."
"Beast Boy," Nightwing added, turning to the green shapeshifter, "go alien."
Beast Boy grinned. "Thought you'd never ask."
A bright flash of green light lit up the beach, and a moment later, Beast Boy stood there as a hulking, four-armed alien with dark armor-like skin, glowing yellow lines, and gravity-controlling fists. "Galilean mode: Activated."
Everyone took a step back as the sand beneath him started to compress under his influence.
"He's gonna regret inviting us to this party," Beast Boy rumbled.
Nightwing gave a final nod. "Everyone else, hang back. We'll observe and adapt. Remember, this isn't a fight—it's a test. Let's show our guest just how serious we take our games."
---------------------------
Naruto floated silently beneath the crystal waters surrounding the island, the ocean wrapping around him like a velvet curtain. In the silence of the deep, his golden chakra flickered and danced like sunlight refracted through glass. He sat in full Bijuu Sage Mode, suspended in meditation—his body glowing, his mind anchored deep within himself.
His cloak of golden chakra rippled outward, disturbing no water, yet marking his domain like a silent current of power. Nature energy poured into him from every direction—Earth's rich, vibrant energy was far denser than what he'd ever experienced in his own world. It buzzed with life, tension, emotion.
His enhanced senses could hear the gentle rhythm of fish swimming nearby. He could feel the vibrations of Beast Boy shifting forms on the surface. He could even taste the faint scent of ozone carried by Bumblebee's electric field high in the sky.
But for now, none of that mattered.
He was inside.
Within the familiar space of his subconscious, the great stone pipes and shallow water echoed with a deep, ambient hum. The massive seal had long since faded. Now, the area felt less like a cage and more like a sacred temple—the temple of the Nine-Tailed Fox.
Kurama lay comfortably in a curled heap, the ambient glow of Naruto's chakra giving his fur a warm, fiery shimmer. His ears twitched lazily, and his eyes—vast pools of ancient intelligence—cracked open with mild curiosity.
"This," Kurama said with a yawn, "is the first time we've been able to cut loose with no war hanging over our heads. No Akatsuki. Just a bunch of overpowered kids in tights."
Naruto chuckled, still seated in lotus pose within the seal space. His voice echoed calmly through the chamber. "Yeah… and for once, we don't have to hold back to protect anyone. It's just us. A perfect field test."
Kurama's grin widened slightly. "Let's play with them."
Naruto smirked. 'Careful. That sounds like something the old you would say.'
Kurama snorted. "Maybe. But you and I both know this world has its own monsters. And they won't all be this friendly. We need to know how far we've come."
Naruto's face turned serious, the playful light in his eyes replaced with resolve. 'I'm eager to see how strong they really are. Superboy's chakra—or whatever that energy is—feels… heavy. He's stronger than me physically, probably even without trying. But he's not the sharpest blade in the armory.'
"Starfire's worse," Kurama added, stretching his limbs. "She's a living sun with arms. One hit from her at full power could shatter bones. Be careful."
'Wondergirl's strong too… But I think the others will be easier to handle. Blue Beetle has some sort of armor AI. Beast Boy's unpredictable but not dangerous unless he pulls something crazy. The rest? I can end most of them with a single hit—assuming I don't get tech-blasted in the face first.'
Kurama narrowed his gaze. "Don't get cocky. The tech here is unlike anything back home. If you see a toaster flying toward you, don't assume it's just for bread. It might shoot lasers."
Naruto snorted. "Yeah, noted. No trusting kitchen appliances."
Kurama's tone softened slightly. "Just fight the way you always do. Use your unpredictability. Use your clones. I'll keep an eye on the field. If anything happens outside your range, I'll react with the chakra limbs before it hits you."
Naruto glanced up. 'Thanks, Kurama.'
Kurama huffed, clearly pleased. "Tch. Don't get sappy on me now. But yeah… I got your back, Naruto. Always."
A silence settled between them, filled with the hum of energy and mutual respect.
Naruto slowly opened his eyes back in the real world—still underwater, his pupils glowing like twin comets.
'Let's see what Earth's finest can really do…'
And far above, on the island…
A faint BOOM shattered the calm—the signal.
The game had begun.
But Naruto? He was already moving.
