Update: This chapter has been updated for this scene that I felt should've been more fair on the fighting scene, and shouldn't have made Naruto too OP'ed.

I don't own anything that belongs to their respective owners, so enjoy the chapter.

Chapter 7: Secrets from the Past

The Boy Wonder always curious about Naruto's life. He was an enigma as there is no file on him. Anytime he tries to find anything on Naruto, everything's all censored. Even though Naruto has told the team who he is, his mother's reputation and that he was part of Task Force X at one point.

And that's just it, why was Naruto part of Task Force X in the first place? As what Batman informs Robin, Task Force X, nicknamed the Suicide Squad, are made up of a team of supervillains and mercenaries handpicked specifically by Amanda Waller for missions, not even the League could touch upon. Most of the villains that were handpicked, Deadshot, Captain Boomerang, Killer Frost, Bronze Tiger, Killer Croc, have some skeletons in the closet that Waller knows about. Nothing gets passed her.

So, what is the reason for Waller to recruit Naruto? He's already stated that he was in Task Force X, but what was his past? It seems that he's very secretive about it.

Robin has been under night watch duty when going through the security cameras. He's on the Titans computer when going over for any crime in the city. Just a routine check for any more crimes.

"So far, things are quiet," Robin said as he was about to turn in until the computer brings out static. "What the-?"

"Greetings, Robin." Out pop up on the screen was Slade.

"Slade!" Robin cries out, standing from his chair. "What are you up to this time?"

"Oh, it's nothing of some sort," Slade responds coolly. "It's just that I have acquired some digging about that little teammate of yours. Rockstar."

Robin narrows. "What do you want from him?"

"Oh, it's not something I want from him, it's just something about his…past," Slade told him as another window on the screen pops up. "I think you'll love this video."

Robin looks at the video popped up. It shows a bunch of scientists as well as a break in. A blur has killed every scientist in the room, but as soon as the blur stopped, Robin's eyes widen in realization at who it is…

/

In the morning, the Titans are seen having breakfast.

"Happy birthday, Foxy," Blackfire told while giving Naruto a kiss on the cheek.

"Thanks, Komi." Naruto respond grinning. "This is going to be the best birthday I ever had."

"Already got special orders from you, bro." Cyborg states.

"A sweet party for Naruto, this is going to rock!" Beast Boy replied.

"By rock you mean loud music until your ears bleed?" Raven asked in monotone.

"Oh I can't wait to celebrate Friend Naruto's joyous day of his birth!" Starfire declares while setting up decorations.

"Can't wait for that." Blackfire cooed while sitting on Naruto's lap, as the two would make out.

"Sister, please not in front of us!" Starfire cries out while covering her eyes.

Then out came Robin, who came into the room holding a box. He marches down to the counter where Naruto and Blackfire are making out.

"Ahem." Robin spoke but Naruto lifts his finger signaling to wait a little bit. Naruto and Blackfire are too busy making out to pay attention, as Naruto is groping Blackfire's butt while she wraps her legs around his waist. "Raven." Robin spoke.

Raven uses her magic to separate the two of them. "Hey! What was that for?!" Naruto shouts.

"Please, you two were gonna have sex on the counter." Raven told him.

"Yeah, we would." Blackfire states.

"We do have sex around here, even in Cyborg's car." Naruto comments.

"Wait, what?!" Cyborg outcries.

"So, what do ya need, Rob?" Naruto asks the boy wonder, ignoring Cyborg's outcry.

"Well, I would like an explanation." Robin demands.

"Okay, look, whatever the cops say, I was out rave partying. I don't know what that stripper was planning at the time-"

"I mean explain why you have been omitting your past?" Robin told him.

Raising an eyebrow, Naruto asks "What do you mean? I've told you guys that I was part of Task Force X."

"True, but why don't you explain this from your room?" Robin place the box on the counter.

"Dude! You've raided his room?!" Beast Boy asked.

"If you did, have you seen my bra in there? I've been missing it for a while." Blackfire asked, missing the point.

Naruto sees the content of the box, looks shocked. "How did you find these?"

"Where you hid them." Naruto states as he pulls out the items as he lists them. "Tell me what are...a rubber knife..."

He pulls out a green rubber knife with the initials S.A.A.U.S.O. on the side.

"...This yearbook..."

He pulls out a year book with the label Kunugigaoka Junior High Yearbook. This got Naruto tensed up.

"...And of course, this school photo portrait I found under your bed." Robin finish holding up a picture of Naruto with a bunch of students wrapped in yellow tentacles...by a smiling creature dressed as a scholar professor. The picture is labeled "Fun Times with Class E."

Naruto's eyes widen as they shift to narrow. "What gave you the idea, boy wonder?"

Robin hesitantly replies, "I've got a transmission call from Slade." This earns the shocked looks on the team's faces.

"And you do realize that Slade telling you this is just gonna make you jump to conclusions and distrust me, don't you?" Naruto asked him, letting Robin sink in that knowledge. "Cause that is like, bad guy 101, have the heroes to turn against each other."

Robin sigh as he knows Naruto has a point. Slade would want to try to get Naruto kicked out, as he responds "With my better judgment, I knew not to trust Slade's words. So, I'm willing to let you explain yourself."

Naruto smiled at Robin's decision, as he leans on the counter, while everyone leans in to listen to his story. "It happened about before I came to America, I was living in Japan for a while. My mom wants me to have an education, so she sends me off to this private junior high school for the smartest students. It was fine and all, until I got into some trouble with my pranks, the director of the school decides to send me to the lowest class filled with the students who couldn't keep up. It was at this point I've met my teacher, who is that yellow tentacle monster in the photo."

"That alien guy's your teacher?" Beast Boy asked, confused.

"I have never seen one like him before," Starfire respond, not recognizing the species.

"That's because he's my dad." Naruto states simply.

"WHAT!?" they shouted in shock.

"Are...are you meaning to tell us..." Beast Boy stammers trying to process this information in his head.

"Oh man, I have no idea your mom's that freaky!" Cyborg exclaimed with a nasty image in his head, that he wishes to erase.

Naruto chuckled at their reaction, "Relax, guys. He's not an actual tentacle monster, he's actually used to be human. He's a good guy and genuinely wants to help the students to pass in order to move up to big careers."

"But how did he end up this way?" Robin asked, trying to make sense.

Naruto paused for a moment, unsure if he should tell them. But it must be done for his friends' sake, so he respond. "He looked like this due to the result of an antimatter experiment gone wrong. He wasn't some scientist looking to break scientific grounds or some citizen accidentally got caught in a freak lab accident, he was known as...well, you may have heard of him."

"Who?"

"Reaper."

This caused Robin, Beast Boy, and Cyborg to fall flat on their behind, shocked by the news. Starfire, Raven and Blackfire are left confused.

"Who?" Raven asked.

"Dude, that is just...too much." Beast Boy said while shaking.

"Um, who is this Reaper?" Starfire asked.

"Yeah, I've never heard anything about Naruto's dad before." Blackfire comments.

"To put it lightly, Reaper is the alias of the world-class assassin," Cyborg answered. "People thought he died in a lab accident where he's locked up, but-"

"He was transformed after the antimatter jumped into his cells, as well as the antimatter being the one that destroyed half of the moon." Naruto finished. "He then introduced himself as the alien responsible for turning the moon into a literal crescent moon. The League has a way to cover that up by using a holographic projection, so the moon would look full. At least until they start building it. He got the Japanese and American government to agree to his terms, that he should teach class E-3 of Kunugigaoka Junior High while a member of the government assists him. The students have a job that we have to kill him from destroying the Earth in one year's time, while he educates us as any teacher would."

"Wait, why would an assassin want to teach a class?" Raven asked.

"And why would he want you to kill him? Isn't he your father?" Starfire adds.

"He made a promise to a teacher he befriended a year before the accident. She was then killed by her crazy fiancé who was the head of the project. As for the killing him part? Well, because of the anti-matter, he'll uncontrollably decimate the Earth until he is killed by one year. The weapons they've given us are made of a special material that can kill him, like that rubber knife. It was the only request we were tasked to. In about our last days we've all succeeded together to kill him." Naruto notices the shocked looks at his friends, as he continued "We all didn't like it, killing Korosensei. I didn't like the fact that I have to kill my own father. But with that year, he was the only teacher that believed in us, helped each of us for what we've needed. He will always teach us valuable life lessons in order to prepare us for the real world. Korosensei wasn't just a teacher or an assassin..." a tear dropped from his eye "He was...the greatest father I've ever gotten to know."

Naruto crosses his arms as he looks darkly. "After that, I went on a blind rage. I went after the bastards responsible for what they did to my dad. How they use his blood to try to recreate the incident. I ended up getting into trouble by both the American and Japanese governments for hunting down the criminals and black ops that used my dad's blood to make themselves powerful as well as destroying the research." he paused for a moment, letting tears leak out of his eyes, as he continued, "I've made sure to erase them from this planet."

"Then...when you were in Task Force X?"

"I was in America at the time after I offed the last one who used my dad's blood. Deciding to join Task Force X for that Arkham mission was just to clean house." he states while wiping his tears as he gives a sigh. "I don't blame you after telling you all this. So, I'll go ahead and get packing."

As Naruto walks to the door, Robin places his hand on his shoulder. Confused, he turns around to see the boy wonder's expression.

"As you said, Slade wants me to try to distrust you." Robin stated, as he forms a smile, "So I've decided to trust you, Naruto."

This has taken a surprise turn, as Naruto ask "But…why? Why would you want a murderer in your team?"

"We all have done things we've regretted," Robin stated. "Everyone has skeletons in their closet, but as long as we've learned from our mistakes and our past, we won't let it define who we are. You're one of us, Robin, even with all the questionable stuff you have no reason for us to distrust you."

"Yeah, we'd never kick you out, man!" Beast Boy states.

"You are our friend Naruto, and always will be," Starfire said with a smile.

"As long as you're straight with us, we're all good." Cyborg comments.

"You did what you have to do." Raven told him.

"And you're even way hotter and sexier for a man who spills a few blood," Blackfire said as she gives Naruto a mouthful kiss before releasing him.

"Wow, I don't know what to say, guys," Naruto responds, while Robin raises his fist up.

"You are a value player in our team, Naruto," Robin replied as he and Naruto fist bump.

The moment was cut short when the large tv monitor pops up, showing Slade. "Greetings Titans."

"Slade!" Robin and Naruto call out.

"I hope I wasn't..." Slade stares at Naruto, his eye narrow. "...interrupting something."

"Well, you better tell us what you want right now so you can go back partying at some gay bar. Tell me, do you let them fit those dicks in that eyehole?" Naruto mocked at the one-eyed villain.

Ignoring that remark, Slade continued "As you and your little team have failed to put in the efforts to find out about what I have planned, I'll just show you what I have in mind." the camera turns to show the Sladebots uncovering a large, black machine with red lines. "I hope you all are familiar with chronotron detonation."

The team gasps at the sight of the detonator. Beast Boy cries out "Oh no! Um...what's a crouton detonator?"

"You know that bad movie Clockstoppers? Imagine stopping time permanently." Naruto states making Beast Boy panic.

"Tell us where is it?!" Robin demands.

"You're a clever boy, Robin. I'm sure you and your little friends will figure it out." Slade said while turning to Naruto. "And I'm surprised that you kept the son of that pathetic Reaper around-" the transmission was cut off when Naruto threw a table at the screen.

The Titans look at Naruto, who looks mighty pissed. "That bastard better wish he didn't call my father like that. Cause he'll be experiencing a new kind of hell when I'm through with him!"

"Easy there, Foxy," Blackfire said with her hands on his shoulders. "We will find him."

"And the bomb. We need to fan out and-"

"That won't be necessary." Naruto interrupts the boy wonder as he held up his guitar, "My guitar picks up the transmission and soundwaves from Slade's call. Once I pick up the sound waves...I know where it is."

"But…how?" Cyborg asked.

"Alien-advance tech, curtesy of Mama Haruhana!" Naruto declares as he instantly disappears at an inhuman speed. Leaving a cloud of dust.

"Yo, he went in Mach 2 in a nano sec!" Cyborg comments.

"If it's Naruto, he might be able to find the bomb," Robin said.

/

Naruto was traveling so fast that the wind blew over town. Once he reaches to the sewers, he saw the bomb, which is heavily guarded by Sladebots.

"Let's get this party started." Naruto whispered, as his guitar glows bright orange.

The Sladebots all charge to shoot their laser beams at Naruto, who dodges each of them in his Mach 6 speed. He swings his guitar to smash them all, including the bulkier ones. He jumps up as he swings his guitar, destroying the Sladebots with extreme prejudice.

He then held his guitar as he raises his pick, as he strums his guitar to cause a sonic soundwave that decimates most of the Sladebots to pieces. He saw the remainder ones, as he plays a high-strung note that causes the Sladebots to malfunction. "Cheap-ass, robots." Naruto mutters as he looks at the chrono-bomb. "Like hell I have to deactivate it!" he pulls a cord from his guitar, as he cries out "YYYEAAAAAWWWWWWW!" as he swings his guitar at the bomb, thus sending it out of the building in a follow up explosion.

The bomb was sent sky high, as it gets launched towards the sun.

/

Watching over at the Justice League Watchtower, Martian Manhunter was busy enjoying his cookies while on monitor duty. Then he noticed a twinkle from Earth as it is launched towards the sun.

"Hmm, odd." Martian Manhunter states as he looks over the monitor. "Must be another disaster prevented."

/

Slade watch as another one of his plans foiled thanks to Naruto. He grip at what was going to be the trigger but it isn't really a trigger. The chronotron detonator wasn't a bomb, it was a trap that was going to send out detonator probes in the Titans' bodies to use for blackmail on a certain person of interest.

This wasn't how it should've end.

"I should've realized that boy would find the bomb sooner." Slade stated "He was supposed to be obsessed with finding me. Hell, he could've brought the bomb to the Titans so they can try to detonate it. He's just as smart as-"

"Bugs Bunny?"

Slade turns around with his chair, seeing Naruto in front of him. "How peculiar. How did you find me, boy?"

"Same as how I found the bomb," Naruto said gripping his guitar.

"I see," Slade said as he stands up, walking towards to Naruto. "Well if you must know, the Chronotron detonator was a fake, there was never a bomb."

"Why am I not surprised," Naruto said sarcastically.

"You see, Naruto, I was expecting to find someone to train, someone to mold into my image. Someone to be my apprentice." Slade states "I was originally pinning towards Robin, but after learning who you are, well I reconsidered making you my apprentice."

Naruto scoffs. "Tough luck, you fucking pirate. I don't work for cocksuckers like you."

"Your juvenile tendencies will be fixed. I shall make you my apprentice, as you are Reaper's son."

SMACK!

Slade was launch to the monitor, crashing it. Oh, how he regrets not having a robot double for this kind of preparation.

"DON'T YOU DARE CALL HIM THAT!" Naruto cries out in full rage, as in an instant speed he launches himself at Slade, grabs his chest and throws him across the floor.

Slade rolls over as he rolls back up. He held up his staff as he saw Naruto jumping from wall to wall of his base. "I can study your patterns, boy," he states as he can tell Naruto's going on a rapid speed of Mach 1, he dodges Naruto's punch from behind, as he swings his bo staff towards to hit Naruto across the floor. Naruto only slides down butt stands up.

Naruto was blinded by rage as he held his guitar. He swings it towards to Slade. Slade blocks the attack with his bo staff, as he can see Naruto sweating. "You're getting tired out, boy. Using up that speed is slowing up your stamina."

Naruto kept swinging his guitar but Slade keeps dodging the attacks, as the assassin pulls up his bo staff. Slade hits Naruto's chest makes the boy sent to the ground.

"Such a long time for you to have so much power, but lack the skills" Slade comments.

Naruto was panting heavily, he has used up his speed which resulted in losing his stamina, as well as his strength.

"Your father should've taught you more, I can teach you what he couldn't."

"SHUT UP!" Naruto shouts as he launches himself to Slade, who dodges as Naruto as Naruto ends up stepping on the wall and bounce back towards Slade. He held his guitar to swing it towards Slade, who dodges away and brings out a stick at Naruto, electrocuting him.

"ARGHHH!" Naruto scream feeling his body being completely electrified.

"You have so much power and potential, but wasted on these foolish heroic acts," Slade said as he picks up Naruto by the neck.

"Screw you." Naruto groans with a death glare.

"You are so much like your father...a weak, pathetic man who looks like a yellow octopus freak who wasted his life to protect worthless school children. I would've had the pleasure of killing him myself, while you watch. Seeing your eyes change the way you look at me, maybe I can start with killing your mother." Slade spoke cruelly.

This ticked off Naruto, as he glares at Slade, "You...piece of...SHIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII-!" he cries out in a high pitch scream, causing Slade to drop him while he continues to scream.

"AAAAHH!" Slade cries out as he covers his ears, however, the scream is so loud, his eardrums exploded. The sound waves have damaged the nerve systems of his ears, leaving him only hear nothing. "My...my ears..." he then saw Naruto, who stopped screaming, grab his eye and pluck it out "AAAAAHH!"

Naruto then kicks Slade to the ground. This doesn't stop him, as Naruto grabs Slade by his chest to his leg, as he raises him up while Naruto bends his own knee.

"Hope you like being a cripple," Naruto told him as he's about to raise him down.

"Naruto, stop!"

He stopped, as he turns to see his friends and girlfriend at the base. "What are you all doing here?!" he cries out.

"Stopping you from going too far," Raven told him.

"Dude, you've beaten Slade." Beast Boy states looking at Slade's defeated form.

"He's defenseless. defeated." Robin clarifies walking towards to the scene. "We've won, Naruto. Slade will be put behind bars for the crimes against the city. He won't be doing anything after what you've done."

Naruto turns to his friends, then to Slade as he gives a sigh, finally calming down. "You're right. He deserves a trial for everything he's caused."

SMACK!

Naruto was instantly smacked across the floor, dropping Slade to the ground. Naruto turns around and saw someone wearing the same kind of armor Slade wears, but wears a cat mask and has long purple hair.

"Who the hell are you?!" Naruto cries out, but the mysteriously masked assistant taps her chest plate, as both she and Slade disappeared. "Wait!"

"Self-destruct sequence activate."

"Dammit!" Naruto growls.

"We have to go!" Robin shouts as the whole team exit out of Slade's now former base.

While the Titans get out of the base, he turns to the shadows where Slade escaped, as he thought 'Next time I see your face, Slade, you'd wish you were in hell.'

/

Naruto is standing on the roof of the tower while looking at the sunset. He remembers the past of his father and his moment together...at the very sunset.

'Dad... I'm sorry.' He thought while shedding his tears.

"Naruto," spoke Blackfire who flew towards him, joining him at the sunset. "Are you okay?"

"Yeah, I'm...doing better," Naruto responds sadly. "After everything that happened today, Slade is still out there."

"And he won't be bothering us anyone for a long time after what you did to him," Blackfire states while sitting on the edge. "Come, sit with me," she said as she pulls him down. "Your father would be proud of you."

Naruto puts his head on Blackfire's shoulder. "He sacrificed so much for me and everyone... I just wanted to make sure Slade will never harm anyone again."

Blackfire kiss his head. "Slade will never get us." She states while caressing his face. "You, beating Slade like that was…pretty hot."

"Glad to know that, but I only use violence as a last resort." Naruto replied while kissing her neck. "I didn't want to let you guys see this side of me."

"We all have our emotional moments, Naruto." Blackfire replied "But we can't let them defy who we are."

She stands up while holding Naruto's hand. "Now come on, there's a birthday party waiting for you." she told him.

Naruto smile as he stands up. "Wouldn't miss it."

Unaware of them, they are being watched by a spirit of a yellow alien with a bunch of tentacles. Wearing a black robe with a black blower hat, having a smile. This is Korosensei, Naruto's father.

Korosensei smile as he watches his son. " Happy birthday Naruto." He said before he disappears to the clouds.

/

Soon the Titans celebrate Naruto's birthday. There was cake, presents, and very, very loud music. Naruto loves this, seeing his new-found friends hanging out and partying with him. Robin and Cyborg confront him with a briefcase.

"Happy birthday, Rockstar," Robin said as he hands Naruto the briefcase.

"A briefcase? Why Robin, I have no idea I'm joining in the business world." Naruto replies "But I'm not going to let the man take over the music in me!"

"Nah, bro. That briefcase contains a special surprise for you." Cyborg said.

"We've been working on it for months to help make your powers more, provocative." Robin states.

Naruto opens the briefcase, checking it out and sees the bright, golden light as his eyes widen in awe. "...This...looks...so cool!"

"Hey, you wouldn't believe what dropped by the door." Beast Boy said as he brings out a large create along with tons of presents. "There's gotta be like...30 of these presents. Plus, the crate's from your mom."

Naruto looks at the presents, he grins as he reads the name tags to who's it from. "Looks like they've remembered after all."

"Who?" Robin asked.

"My classmates, along with two of my dad's assistant teachers," Naruto replied as he looks at the large crate.

"What kind of present did your mom sent?!" Raven asked.

"Must be a big one," Cyborg respond.

"Let's check it and find out," Naruto said as he raises up a crowbar out of nowhere, as he sticks it under the top. Once he opens the crate, he looks down to see who's in it.

It was a silver skinned girl with spiky black hair with red bangs and black clips on the side. She has red eyes with black pupils, and black lips, as she wears a gothic outfit consist of a black corset fitting her C-cups, black fingerless arm gloves with red spiky trims, black boots with red on the bottoms. She has a red A tattoo on the center of her chest. She also appears to have been bound to a ribbon with a bow gagged into her mouth.

"Toni!?" Naruto cries out, taking the gag off of her.

"'Ello, luv." The girl named Toni replied. "Yer mum put me in this crate as a birthday gift to you."

/

Meanwhile, at an unknown location, Slade is seen in bed, with doctors in hazmat suits helping him heal.

"You have taken quite a beating, master." spoke the pale old man in the white suit, he is Wintergreen. "Your daughter should be here in a few hours to help take care of you. In the meantime, once the voice collar is installed to your neck."

Wintergreen saw his master twitching his finger as if signaling something. "Of course, master. I shall spread the word about the boy's true father."

/

So, you all thought that this will play out like in Apprentice episode, right? He, he, WRONG! Yeah, I know there are some that are probably disappointed that Slade got easily beaten by Naruto, who's basically a superhuman. Slade on the other hand while may be a tactician, he's nowhere near as fast as Naruto's most unpredictable and instinctive attacks.

Some might say it's a copout and uneven match, but I would like to change up the pace as this is just Act I. Slade will come back, but will he try to even the odds? What is Slade's plan of getting his revenge on Naruto? And what is his relations with Argent? Stay tuned and find out on Rockstar Titan!

Also, I hope you like that I include a Assassination Classroom blend in.

Next chapter, Naruto takes the spotlight in the worst ways to come.
