This is my second fiction and it follows the Dragon Ball Z storyline. I always wondered what would have changed if Gohan had stayed in the time chamber and if he continued to train after the Cell Games. This story pretty much shows what would have happened. Please read and review.
Also I will be putting up a Pokémon story soon, so that is something to keep an eye out for, but my Naruto story will be my main focus until it reaches Shippuden.

Flashback

Chapter 1 – Extra Time

In the hyperbolic time chamber a father and son duo had been training intensely for the past forty-six weeks.

Goku and Gohan were both wearing blue Saiyan battle armour that had definitely seen better days.

'Alright Gohan I'd say we are just about done. Ready to go?' asked Goku.

Gohan stood there in thought. He realised that he had improved a great deal and was a lot stronger but he also had a feeling that there was more he could do. 'No dad.' Said Gohan.

'Hmm what's wrong son?' Asked Goku tilting his head to the side.

'I want to stay and finish the year I feel like I'm close to something more that might help us in the battle.' Replied Gohan.

'Are you sure son? Torturing your body won't make you any stronger.' Inquired Goku.

'I know dad, I just need a bit more time. I'm close to something.' Said Gohan.

'Okay I'll let you train on your own for the next month and a half but don't overdo it.' Conceded Goku.

'Thanks dad.' Said Gohan before going back into the white abyss.

One Week Later

-line break-

'I'm so close. I can feel it.' Complained Gohan

Gohan began powering up again. 'AAGHHH so close.' At that moment Gohan remembered how Piccolo had to die to save him from Nappa because he was too weak, how powerless he felt when he fought against Frieza, then when Krillin was blown up by Frieza and lastly when Frieza taunted Gohan by lying and saying Goku begged for his life before he killed him. 'I won't let anyone I care about get hurt ever again HAAAAAAAAAAAAAAAAAAAAA!' Gohan screamed.

At that moment the dam holding back Gohan's power broke and his power level increased fifty times more that what it had just been.

'Hah wow I never knew I had this much power. But, for some reason I feel so angry.' Said Gohan.

"I wonder what's going on I feel different somehow, as if, my anger, rage and brutality have been released." Thought Gohan.

'Pathetic monkey you are still no match for me.' Snickered a voice.

'Who is there?' asked Gohan.

'Stupid monkey. You never learn.' Replied the voice. Gohan looked around and finally found the source of the voice.

'FRIEZA!' yelled Gohan. Gohan charged and sliced Frieza's head off with a reverse chop and the rest of Frieza's body crumpled to the floor.

'Pathetic little kid you haven't changed a bit.' Said a new voice.

'GRR show yourself.' Growled Gohan.

Nappa appeared laughing at Gohan.

'You'll pay for what you did to Piccolo, Masenko!' screamed Gohan. The blast raced towards Nappa and tore through his stomach, killing him.

"What's going on all of these guys are dead." Thought Gohan.

'Eraser gun!' called a new voice. Gohan jumped to the side.

'That is it, Kamehameha!' yelled Gohan whose wave vaporized Recoome's body.
'*huff* *huff* man I feel so... tired.' Said Gohan before passing out and reverting back to normal.

Later

-line break-

When Gohan finally awoke he found himself in his bed from the hyperbolic time chamber and was confused as to how he got there.

'Dad, dad where are you?' asked Gohan getting out of bed and looking around.

'Oh hey Gohan you're up.' Said Goku teleporting in front of Gohan.

'Dad what happened all I remember is feeling really angry and then passing out?' asked Gohan.

'Son you reached the second level of Super Saiyan.' Said Goku.

'W-what you can't be serious dad.' Stammered Gohan.

'It's true you have surpassed me I don't have nearly as much power as you do now hahaha.' Laughed Goku while giving the Son grin and scratching the back of his head. 'Oh it is also time for us to leave now, you were out for a couple weeks, our time is almost up.'

'Okay dad I think I'm almost ready anyway.' Said Gohan.

In Last Week Of Training

-line break-

"Hmm I feel as though there is more power to the Super Saiyan transformation. Maybe there is another level beyond the second level." Thought Gohan.

'Hey dad.' Called Gohan.

'Hmm. What is it son?' said Goku appearing in front of Gohan.

'Can you teach me Instant Transmission?' asked Gohan.

'Sure I guess but it will probably be the only thing you will be able to do before we leave because it'll take a while to learn, are you sure you're ready?' asked Goku.

"Hmm I could try for the next level but on the other hand I think I've got enough power and instant transmission would be really helpful." Thought Gohan.

'Okay dad teach me instant transmission I'm ready.' Replied Gohan happily.

Outside the hyperbolic time chamber

-line break-

'When are Kakarot and his brat going to come out of the blasted place they're wasting the time of important people and if they don't get out in the next ten seconds I'm going to go in there and drag them out!' ranted Vegeta.

'Oh what is that it's huge?' Gasped Trunks.

'Kakarot?' questioned Vegeta.

'No it's... G-Gohan?!' stammered Piccolo.

'Hey guys did we take too long?' asked Goku appearing in front of them with Gohan next to him.

'Kakarot what did you do in there and how is that brat so strong?' shouted Vegeta.

'Well we trained and I have no idea, Gohan got this strong on his own in the last month we were in there.' Laughed Goku while scratching his head.

'Gohan... what happened to you in there?' asked Piccolo.

'It's very simple Piccolo, I became strong enough so you don't have to worry about me anymore and so that I can protect you guys now, not the other way around.' Replied Gohan calmly.

'Please you think you can beat Cell, you're just a child.' Scoffed Vegeta. In a flash Gohan was standing behind Vegeta leaning on his back.

'I may be a kid but I am not going to let Cell destroy this planet. The earth is my home and I won't let anyone destroy it.' Said Gohan.

'Goku, did you teach Gohan how to do instant transmission?' asked Trunks.

'Yeah but he didn't use it right now that was pure speed.' Said Goku.

"Impossible the brat moved so fast even I couldn't keep track of him. It's preposterous." Thought Vegeta.

'Come on Gohan lets...'*grumble* everyone looks to Goku's stomach. 'Uh Mr Popo can you make us something to eat please?' asked Goku holding his stomach.

Mr Popo made them heaps of food and Goku and Gohan ate it in typical Saiyan style.

'Uh Goku wasn't there enough food in the chamber?' asked Tien.

Goku spoke with food in his mouth and so the words were lost on them.

'Okay Goku why don't you try saying that without your mouth full.' Said Piccolo.

Goku swallowed 'Ugh disgusting.' Commented Piccolo.

'What I said was Gohan and I can't cook very well so it's been a really long time since we had a good home cooked meal.' Goku said. 'When I mean, can't cook well I really mean we can't cook at all this one time I asked Gohan to fire me up a roast beef and he set my hair on fire haha.'

'Thanks Mr Popo.' Said Gohan.

'So Trunks tell me what's been going on?' asked Goku.

Trunks filled Goku in on Cell absorbing Eighteen and his whole tournament idea.

'Hmm a tournament, sounds interesting.' Said Goku. 'Hey Mr Popo do you still have the clothes I left here?'

'Sure they're around here somewhere.' Replied Mr Popo.

Goku changed back into his standard orange gi.

'Goku I'm sure my mum would make you more armour if you asked her.' Said Trunks.

'Nah that's okay I want to fight as an earthling.' Replied Goku.

'Piccolo can you give me an outfit like yours?' requested Gohan.

'Sure kid it'll make you look real sharp. HAA!' Said Piccolo. A smaller version of Piccolo's outfit was now on Gohan.

'Thanks.' Said Gohan.

'Kakarot do you think you can beat Cell?' asked Vegeta.

'Well I can't say for sure since I haven't seen him since he absorbed Eighteen. I'll go check.' Said Goku before teleporting.

Goku reappeared in about a minute.

'Well what do you think Goku?' asked Trunks when he reappeared.

'Honestly he has become a lot stronger than I thought he would, but I won't know how tough he is until I fight him. But if I were to fight him right now, I'm pretty sure he'd beat me with only a little bit of trouble on his part.' Spoke Goku calmly.

'Oh okay.' Responded Trunks crestfallen.

'Well you can always go into the hyperbolic time chamber again...' began Piccolo but he was cut off when Goku spoke.

'Actually Gohan and I don't need another turn we can just train on the outside for the rest of the time, after all we've got nine days.' Reasoned Goku.

'Hah I bet you just can't handle the training.' Mocked Vegeta.

'Ha if you think torturing your body is the way to get stronger then be my guest. Later.' Said Goku before he and Gohan flew off.

At Korin's Tower

-line break-

'Hey Korin.' Said Goku as he and Gohan touched down at Korin's tower.

'Ah Goku how are you, do you think you're strong enough to fight Cell.' Inquired Korin who was a white cat holding a wooden staff.

'Well that's what I came here for.' Said Goku. 'Can you compare my power level to Cell's and tell me who is stronger?' asked Goku.

'Sure just give me a second to get ready.' Said Korin who stood in front of Goku before Goku started powering up.

'HAAAAAA!' shouted Goku in his Full-power Super Saiyan form. His power rose dramatically and started to cause the tower to break.

'GOKU STOP!' shouted Korin in order to be heard over Goku's screaming.

Goku heard Korin and stopped powering up before relaxing.

'Well that was about half.' Said Goku.

Korin sweat dropped while thinking "That was only half?"

'So what do you think?' asked Goku.

Korin thought about it for a very long time and considered twice of what he just felt to what he could feel of Cell now.

'Well, if that was half. Hmm I would have to say that Cell would beat you.' Concluded Korin after some time.

'Ok that's what I thought.' Said Goku which made Korin comically widen his eyes due to the fact that he already knew he couldn't beat Cell yet still almost destroyed his tower.

It was at this time Gohan had been thinking about his own power level and wanted to ask Korin how his power compared to Cell's.

'Um excuse me, master Korin?' asked Gohan waiting for the guardian to look at him before continuing.

'If what you just felt from my dad was only ten percent of his current power do you believe he would be able to beat Cell?' asked Gohan stoically not giving too much information away.

'Why of course. If that was only ten percent of his maximum he could destroy cell four times over easily.' Replied Korin.

'Thank you master Korin. Bye dad I'm going home.' Said Gohan before he vanished away without needing to put his two fingers to his forehead.

"Gohan you keep making me prouder and prouder. I know you will beat Cell." Thought Goku.

Nine days later

-line break-

The Z-fighters had arrived on the scene in time to witness a, as Vegeta put it, 'big haired buffoon' get slapped away by Cell and go flying into a cliff.

'Uh I just slipped, yeah the tiles were wet.' Defended the buffoon who was clearly outmatched.

'So who's first, Goku?' inquired Cell.

'No Cell, I shall be your opponent today.' Said Gohan in a serious tone of voice.

'HAHAHA you amuse me child but a simpleton like you would stand no match against me despite being a Saiyan. After all you forget I have assimilated your cells into perfection.' Said Cell while putting his hands out to the side.

Gohan narrowed his eyes at that and gave a slight growl while flaring his KI. Gohan reached over to his left shoulder with his right arm and took off his weighted cape, he flung it right past Cell's head and into the mountain the buffoon had slammed into previously and utterly destroyed the cliff leaving only rubble. Cell merely raised an eyebrow in surprise while the buffoon's eyes widened to insurmountable levels.

Gohan then charged at Cell in the blink of an eye and delivered a strong right to Cell's gut.

'Ughoghu.' Choked out Cell as he coughed out blood.

An announcer near the buffoon begun to commentate on the recent turn of events.

Gohan then pulled out his fist and in the blink of an eye, gave Cell a side kick which sent him into another mountain which also shattered.

Cell came out of the rubble heavily damaged blood rolling down his forehead and across his cheeks, with his right leg twisted to the side with his left arm destroyed.

'Ugh HAAAA.' Shouted Cell as an arm emerged from his left shoulder.

'You brat how dare you!' shouted Cell as he twisted his leg back into place.

'You shouldn't have underestimated me Cell. It will be your end.' Said Gohan in a cold tone.

'You insolent, arrogant child. I will destroy you and kill everyone on this planet!' shouted Cell.

Gohan scoffed before flying at Cell with two KI blasts in his hands.

'HA!' shouted Gohan blowing off Cell's right arm and leg.

'DAMN YOU!' screamed Cell in pure rage as he regrew his right arm and leg.

'When you threatened to destroy this planet you overlooked one fact, that this is my home and I won't let anyone destroy it. I am the Earth's protector and as long as I live you won't touch this planet, ANY OF MY FREINDS OR MY FAMILY!' shouted Gohan as he started powering up and turning into a Super Saiyan two.
