Author's Note: This story has been in my mind for a long time. Dragonball Z and the Justice League animated show crossovers have been done before, but I wanted to try my own take on it.

Summary: Near the end of the training within Hyperbolic Time Chamber, young Gohan goes too far into its depths, and ends up in another universe, (We never know exactly what the limits of the HTC are, so I'm going to use some creative liberties and say that it can go anywhere.) Join him with the Justice League on their adventures.

Second Note: People from the beginning are going to be wondering how Gohan's strength matches up to the rest of the league, mainly Superman. From the DBZ timeline, Gohan will not have achieved Super Saiyan 2 yet, because he was still in training. He will be close to Full-Power Super Saiyan, just slightly weaker than he was at the Cell Games. When comparing it to the power of the Justice League, I'm basing it off of some evidence from previous shows. In Superman the Animated Series, Superman had trouble lifting up a plane, while Adult Gohan as Saiyaman in DBZ could easily. Superman is quite a bit stronger in Justice League than in STAS and Teen Gohan is stronger than Adult Gohan. So, by my logic, 10/11 year old Gohan in his normal state will be a little stronger than Superman, while as a Super Saiyan, he will be much stronger (Super Saiyan increases strength by 50x.) Not to mention, Gohan is a far more skilled fighter. As for Super Saiyan 2…we'll see what happens. This story starts in the last scene in the Justice League episode, "Starcrossed Part 1."

The Justice League: Warrior Unleashed

Chapter 1: Accidentally Inter-Dimensional

John Stewart, also known as the Green Lantern, punched the newly created force field valiantly, but to no avail. It just wouldn't budge. Beside him laid the unconscious forms of Superman, Flash, and Martin Manhunter, all of whom had fallen in various ways to the force of the Thanagarian Empire.

'I can't believe how quickly things have changed around here," Green Lantern thought, continuing his assault, 'To think I trusted Shayera all this time, when right behind my back, she was planning to turn on me at any second in order to please her race. I was almost in love with that woman…but now, I don't know what's right anymore.'

Giving up his punches, he took a step back and prepared to fire an energy bolt at the shield, when the soft fluttering of wings caught his attention. Turning around, he was met with none other than Hawkgirl, clad in her Thanagarian garb, looking no less beautiful.

'Ignore it, John.' Green Lantern thought, mentally shaking his head, 'It's all just a ruse.'

Seemingly calm, Hawkgirl pleaded, "Don't fight us. We're trying to help you."

Enraged, John turned around, "Do you ever stop lying?!"

"It was for your own good," Hawkgirl continued, walking up to John, "You've got to trust me."

Instantly, Green Lantern's ring was in her face, glowing with destructive power. "Why?! Who's side are you on?!"

Hawkgirl's eyes softened, reminding John forcefully of the first time he had seen her whole face; he had taken off her mask in the med bay of the WatchTower after the tumultuous battle with the Royal Flush Gang, and the two had shared a kiss for the first time. It was practically a night of magic.

Even now, as Green Lantern tried to tell himself it was all a trick, his arm subconsciously began lowering.

'Can I really trust her again? After all she's done?'

"Don't you know?" Hawkgirl whispered.

That did it for him. After a few more seconds of glaring, Green Lantern's ring flickered off, the glow surrounding his body faded, and his arm dropped to his side.

All of a sudden, Hawkgirl's right arm snapped up, and John's face was met with the cold, hard metal of her mace. Releasing a loud groan, John dropped to the ground, his face sinking slightly in the sand. With the last amount of strength he had, he lifted his head up to meet Hawkgirl's determined face, as her betrothed, Hro Talak, walked up to meet her.

"I'm sorry, John." Hawkgirl said solemnly.

Giving up, with his heart breaking inside, John's face fell back into the sand.

'What are we going to do now?' Was his last thought as he lost consciousness.

Gohan woke up from another one of his fitful rests, breaking out in a cold sweat. He had had yet another nightmare where Cell had somehow gotten in to the Hyperbolic Time Chamber while he was training. Only this time, instead of killing his mom and Piccolo, Cell had killed his father, driving a hand through his chest. And once again, Gohan hadn't been powerful enough to stop him.

'Why does this keep happening?' Gohan thought, 'I need to stop worrying about what hasn't happened yet? Cell doesn't know about this place, and even if he did, my dad would stop him for sure.'

But even as he tried to reassure himself, he had his doubts. Goku had said from the beginning of their training that he wasn't strong enough to destroy Cell, and as they were entering the ninth month, that statement hadn't changed.

'And yet, Dad is always so carefree, as if there isn't anything to worry about.'

True, the two had gotten a lot stronger during their training, and Gohan was surprised to find he was sparing almost evenly with his father now, but still, what could Goku be hiding?

Suddenly, a mop of spikes with a smiling face attached to it leaned in through the curtain around Gohan's bed.

"Come on, Gohan!" His father shouted, "Get up! I want a nice breakfast before we get to training today."

Smiling, Gohan leapt out of bed. "Okay dad!" He paused to wipe a lock of golden hair out of his face. He quietly marveled at how natural it felt to be a Super Saiyan now, even when he slept. It was as if Saiyan power knew no limits.

A few minutes later, the two Saiyans were at their dining table, gorging on their customary hall of food. Well, one of them was anyway.

"Hey Gohan, what's the matter?" Goku asked, swallowing a mouthful of spaghetti. "You've barely touched your food."

"Huh?" Gohan mumbled, jerking out of a daze. "What?" He looked down to discover he had been twiddling a meatball between his fingers.

"Oh, sorry dad. Guess I've just been a little stressed today."

Smiling fondly, Goku put a hand on his son's shoulder.

"Hey, don't worry about it. When the time comes, we'll be ready for Cell, and any tricks he might have up his sleeve. There's nothing to be afraid of."

Gohan looked up at his father and couldn't help but smile back. The infamous Goku smile was pretty darn infectious.

"Thanks dad." He said, "Hey, do you mind if I go outside and put in a little extra training before we start?"

"Sure, son." Goku nodded. "But just make sure not to go too far. You know how dangerous it can be to go deep into the Hyperbolic Time Chamber alone."

Gohan nodded back, standing up from the table. "Don't worry, I shouldn't be gone too long. I'm just feeling a little restless right now."

"Well, then get on out there!" Goku cheered, clapping his soon good-naturedly on the back. "I expect you to give me your all when we spar today."

Giving his father a thumbs up, Gohan opened the door and stepped out into the unknown depths of the chamber. He looked around, seeing the blank witness he had grown accustomed to these past eight months, took a deep breath, and powered up, feeling the familiar rush of power soar through his veins.

"Let's go."

Ten minutes later, Gohan was coming close to breaking a sweat as he repeatedly threw lightning-fast punches at the air, his golden hair flying around his face. He pushed his feet off of the ground and flew into the air, repeating the same routine.

'C'mon, Gohan.' He thought, 'You've got to do better than this. Dad is counting on you to make him proud.'

Unleashing a snarl, he threw a large ball of energy from his left hand onto the ground, and then threw another from his right, both of which created a large explosion beneath him. He rushed to the ground to steady himself and landed in a fighting stance. Tensing his muscles, he held his fists out in opposite directions and let his power surround him in a golden aura.

"I've got…to surpass…a Super Saiyan!" He grunted, trying as hard as he could to raise his power level even higher. But to his shock, and to an extent, annoyance, it would not go any higher.

Gasping for air, his golden aura vanished, and he fell to his knees.

"What is going on?" He asked himself. "I feel like there's this power in me that's trying hard to come out, but no matter what I do, nothing seems to happen!" He stood up slowly and wobbled a little, the exertion from releasing his energy hitting him.

"I guess I'll have to wait another day and see what happens." Taking a deep breath, he fixed a smile on his face. "At least now I can spar with dad!"

Growing excited, he looked up to where he knew the entrance to the Hyperbolic Time Chamber was, and to his surprise, he found it to be merely a speck in the distance.

"Heh, whoops." He said sheepishly, rubbing the back of his head. "I guess I traveled out a little farther than I thought."

Rising hesitantly into the air, he began to fly back, looking around in all directions.

"I'd better be careful though. Dad said this place can be subject to a lot of…"

All of a sudden, large, orange flames erupted from the ground and headed towards the young Saiyan.

"CLIMATE CHANGES!" Gohan yelled, jumping backwards in the air to avoid the flames from hitting his bottom. To his horror, the flames rose higher than him and completely obstructed his view of the entrance. He put on a burst of speed, attempting to fly around them, but no matter which direction he turned, the flames were there to greet him.

"I've got to get out of here somehow!"

Giving out a yell, he let his energy surround him once more in an attempt to fan away the flames. At first, nothing happened, and Gohan began to feel silly. But very gradually, the flames began to swirl around him, as if working in tangent with his energy. Soon enough, all the flames had been sucked away from the ground, and had evaporated into nothingness.

Gohan sighed with relief, and was about to congratulate himself, when a burst of cold wind suddenly hit him with full force.

'Oh no! I forgot about the cold!'

Before he could power up again, the wind blew him off his feet and sent him tumbling head over heels though the frosty air. For several minutes, he was tossed to and fro amongst the empty the space, so much so to a point where he didn't even know where he was going. He tried to fight against it, but the temperature dropped to a point where his hands and feet became encapsulated in ice. He could only watch in horror as it traveled up his body and neared his head.

"NO!" Gohan shouted. "I DIDN'T COME THIS FAR TO WIND UP IN A BALL OF ICE!"

Having had enough, Gohan powered up to the highest he could go as a Super Saiyan, his power rushing out in rapid waves that shattered the ice covering him like fine glass. For a brief moment, nothing else could be heard but the sound of his screams. Then, all at once, the ice stretching out in mountains around him met the same fate, all creating an almighty crash that shook the endless limits of the Hyperbolic Time Chamber.

After that, there was silence.

Gohan stood alone in the air, his golden aura continuing to warp itself around him. He allowed a small outtake of air to escape his lips.

"Whew," He uttered, letting his aura fade away, "I'm sure glad that's over. It's a good thing the wind didn't blow me too far away…."

He paused at his own words.

"It didn't blow me that far away…did it?"

Feeling a sense of trepidation, he turned to where he thought the entrance was, and found…nothing.

"…No."

He spun in all directions, searching frantically, but was met with the same empty void he had seen all too much in the past eight months.

"No!" 'This can't be happening to me! I can't have gone that far! How am I going to find dad now?!'

Growing desperate, he tried to search out for his father's energy, but once again, he felt nothing.

"NO! DADDY!" He cried out, but the only sounds that met him were his own echoes. He could feel a wetness forming around his eyes and scrubbed at his face to wipe away the tears, but his own emotions failed him as a sob escaped him.

'I'm going to be stuck in here forever.' Gohan thought, 'I'm never going to be able to see dad, or mom, or Piccolo, or anyone ever again.'

He began to fly out in a random direction, knowing that staying put wouldn't do any good, but it seemed that no matter how far he flew, nothing in the environment changed. He continued flying around for another hour, but nothing changed. He even tried raising his power again to alert his father of his distress. But once again, nothing changed.

"It's hopeless." Gohan said dejectedly. "I've just been flying in circles for the past hour. No matter where I go, all I see is white."

He sunk to the ground slowly, dropping out of Super Saiyan in his depressed state for the first time in several weeks. Hugging himself, he allowed several more harsh sobs to escape him.

"After all that I've been through," He murmured to himself, "After the aliens I've fought, gotten beaten up by, and even killed, this is how I'm going to go down. Lost forever in nothingness."

At the tender age of ten, approaching eleven, he had not been one to consider how he was going to die, even though he had seen it happen to his friends, mentor, and even to an extent his own father. But now, he had lost all hope.

"If only I had listened to dad. If only I had stayed inside. If only…"

Unexpectedly, a spike of energy snapped past Gohan's mind. Breaking his reverie, he sat up.

"What was that?"

He closed his eyes and allowed his senses to take over. The energy he felt was not as high as his or his father's, but it was substantial. Looking deeper, Gohan could sense a few other energy signatures close by the first. A few were obviously strong, while two others were much lower, but had a large potential that intrigued the young Saiyan. Either way, they weren't too far away.

"Maybe following these will lead me back to dad!" Gohan exclaimed, powering up and following his senses. "…I hope."

He increased his speed, breaking the sound barrier in his desperation to be free from his barren prison. He drew nearer and nearer to the energy signatures, and after a few more minutes, he could finally spot a small black dot in the distance. He gave a grin.

"Finally!"

However, as he got ever closer, that grin began to fade. Instead of the entrance to the chamber he had been hoping for, he saw the beginnings of tall buildings and skyscrapers. Closer yet, and he could see streets on the ground with American cars parked on the sides.

"It…It looks like one of those cities in America Mom sometimes talks about." Gohan said, looking on in awe. "I wonder if…WOAH!"

He stopped in midair as he beheld the sight in front of him. The city was there, as he had seen coming up to it, but it only seemed to begin where the whiteness of the Hyperbolic Time Chamber ended. Looking to the left, Gohan expected to see some stripe of energy separating the two locations, but one could not be found. It was as if the two locations merely…coexisted with each other.

"How is this even possible?" He said to himself. "I thought the Hyperbolic Time Chamber was supposed to be this blank, empty void. Where did this come from?"

Thinking hard, Gohan tried to recall what his dad had warned him about, and only came up with the advice to not go out too far.

"He…never actually did get trapped himself, did he? So…he wouldn't know what the depths of this place truly were. Is it possible this could be a different world all together?"

He floated to the rip between the two worlds and slowly reached out with a hand in an attempt to touch it. But he paused.

"Wait. If I go there, I could make things worse than they already are. Maybe I should just…"

He turned back, and was met with the cold, white background once again.

"Then again…" Gohan said nervously, "Anything's better than this."

Taking a deep breath, he moved up to the rip, reached out with a hand, and allowed it to slide through.

For a moment, nothing happened. But then, everything seemed to explode around him in a bright light. Gohan covered his eyes immediately with his free hand, and when the light died, he noticed that nothing had changed. Except for one thing.

Looking down in horror, Gohan saw that his hand was being slowly sucked in through the rip. He pulled back with all his strength, but it seemed this inter-dimensional force far outclassed the young Saiyan. He grabbed with his other hand, but it only resulted in that hand getting trapped as well. Soon enough, his legs had become ensnared. He twisted himself to face the white space of the Time Chamber as he was sucked further into this new world, his head the only part of his body remaining.

He knew it was hopeless now, but as the remaining part of him slid though, he hoped that somewhere, his dad could hear him.

"DAAADDDYYYY!"

Another bright flash of light occurred, and this time, Gohan was knocked unconscious as he left the world he knew and entered the unknown.

And what was unknown to the half-Saiyan, was that his life was about to get a whole lot more complicated.

Author's Note: And that's the start. Quite a piece of work this chapter was. Somehow, I always felt my wording and descriptions seemed off, or just a little repetitive. But hopefully it will get better from here. And for anyone who's wondering, the energy he felt was Wonder Woman's. After getting captured by the Thanagarians, Superman was put under red sun radiation, so his power is basically gone. As for the two with potentially high energy signatures, well, that will be revealed later. You can guess if you want. Aside from following the JL plot, I'm making it up as I go. Anyway, read and review please. If you have any criticisms, be constructive, and if you have any ideas on how you'd write the story, I'd love to hear them.
