Back on the Battlefield
Vegeta was being pummeled by Frieza, there was blood flying from Vegetas mouth with every hit, and his condition was worsening with each blow, if that was even possible.
Freiza had a look of absolute glee on his face as he was viciously and brutally attacking Vegeta, savaging every ince he could reach, punch kick kick blast kick, it was relentless, never letting up.
"Give it up Vegeta!" yelled Gohan, "You can't win".
"Nooo" Vegeta managed to croak out"
"HAHAHAHAH" laughed Frieza evily, "It seems you own't be the one to defeat me after all, no-one can kill me, the mighty Frieza"
And with that he continued his attack, as Cell watched on with amusement and Gohan looked in horror.

Vegeta was taking a beating from Frieza, it was a one sided fight, much like their first, Gohan was watching, mouth wide open as he witnessed this horrific act.
Vegeta was well aware of the thrashing he was taking, he took a punch to the face, and had a flashback from his first fight with Frieza, he was being beaten on, then he snapped back to reality, and got kicked in the gut, then whoosh, another flashback, Frieza had him by the throat, holding him in the air while beating his body, then he was back again, Frieza was above him now, and then he backflip kicked Vegeta in the head, sending him sailing towards the ground, on his way down, Vegeta remembered Frieza killing him on Namek, enraged by this, he mustered his little remaining strength and stopped his fall, landing on his feet.

"Frieza" Vegeta managed to splutter out as he got to his feet, "Too long have you haunted my dreams, my nightmares, even long after Kakarot defeated you, I was still afraid, all my life you intimidated me, acting as though I was your own son, all because you murdered my father, the King of all Saiya-jins."
"You were cowardly Frieza, afraid of what we would become, you were running from your fate, you are no warrior, a true warrior would have let the Saiya-jins live, just so he could experience the thrill of a decent challenge, but you out your tail between your legs and mercilessly slaughtered them, you made one fatal mistake, you let the Prince survive, and now Frieza, now I shall avenge my race, all the Saiya-jins you killed, I shall avenge my Father, you will not haunt my sleep anymore!"

He launched himself at Frieza, the ground beneath him collapsing from the force he took off at.
"It looks like the monkey has some fight left in him" said Frieza cheekily.
Vegeta must've caught him off guard, because one quick hook to the face sent Frieza flying, Vegeta flew after him and quickly followed it up with knee to the gut, then he started pounding away, exerting all his energy into the physical onslaught, blood was spilling from Frieza mouth and leaving stains all over Vegetas combat suit.
"Wow, I didn't think he was up to this" said Gohan surprisingly, "But he can't keep it up forever" and he went back to watching the match intently.
Vegeta then gave a two fisted smack into Friezas back to send him sailing away, and then he stood, charging up a blast, as Frieza turned around, he let it fly.

RoSaT

There was a huge explosion, as Goten had sent a Kamehameha flying towards Trunks, and Trunks had tried countering it with a Galick Gun, but it had exploded in his face.
When the smoke cleared, the two SSj3s stood smiling at each other.
"This fight is superb" said Goten happily.
"Yes, unlike anything we've both fought before" replied Trunks with a smirk on his face.
And in the blink of an eye the two had disappeared and were moving many times faster than the speed of sound, shockwaves all over the room as they were both exchanging lightning fast blows, punch: blocked, kick: blocked, every 5th or so hit was connecting, and when it did, the reciever would let out a gasp of pain, but then instantly recover and counter, it was a fierce battle, but niether of the two were letting up.
Then, the both lept back and powered up, Trunks had his hands at his side powering up a purple blast, as Goten had started yelling KAAAAA, MEEEEEE, HAAAAAA, MEEEEEE, HAAAAAAAA!
With that last HAAAAAAAA! Trunks yelled out Galick Gun! and the two blasts connected and exploded immediately on contact, there was smoke everywhere...

Back at the Battle

Frieza emerged as the smoke cleared, looking in the same state as Vegeta, much worse for the wear, open wounds spilling blood everywhere and one arm out of commission.
"Well well well" said Vegeta cheekily with a smile on his face, "It seems that last attack did quite a bit of damage to you"
"Shut up you monkey, I can still beat you" replied Frieza angrily.
"He's right" right thought Vegeta worriedly, "I'm in no state to beat him, my energy is gone, but I must go on"
And Frieza and Vegeta started at it again, matching blow for blow, but Frieza knew Vegeta wouldn't be able to hold it up, so he thought to himself, "Slowly does it, he won't last much longer".
Vegeta started becoming lax in his technique, not keeping his guard up, slow on the blocking, and not countering as often as he should, Frieza was taking advantage of this and getting extra hits in, always sapping away Vegetas energy.

Gohan was watching in awe, but he knew Vegeta was going to exert all his energy soon, as Frieza nastily gave a head smash and sent Vegeta towards the ground, suddenly Gohan snapped out of his trance and remembered something, he had a flashback to after the Buu fight, on Korins tower, he had recieved a whole bag of Senzu Beans from Yajarobe.
"Alright!" he thought as he dug into his pocket and grabbed one, "Vegeta! Catch" he yelled as he threw a Senze Bean at Vegeta, Vegeta reached a hand out and caught it, he hastily popped it into his mouth and swallowed it, suddenly, all signs of injury, battle and fatigue left him, he was stronger than before, being so close to death, he had recieved a Zenkai.

Frieza had a stunned look on his face, watching as lightning crackled all round Vegeta and he radiated with pure energy, then, all of a sudden Vegeta had teleported above Frieza, he smiled and knocked him straight towards the ground, smiling with complete satisfaction at the look of horror and pain that Frieza wore as he went flying towards the dirt.
As Frieza got up, Vegeta yelled out to him, "This is my time Frieza, for my father, for every Saiya-jin you layed even a finger on, and for all those years you tormented me, I shall even the score!"
He extended both arms and palms open started charging up a blast, "Say good-bye Frieza, you will meet your demise again, here today, by the hands of Prince Vegeta".
"FINAL BANG ATTACK!" he yelled out as a bright energy wave was sent towards Frieza.
Frieza just stood there, paralyzed in fear as he was obliterated by the blast into nothing.

Gohan was flying towards Vegeta to congratulate him when out of the blue, a voice said "Well, you managed to get rid of him, but now you have me to face, I wouldn't celebrate just yet"
The smiles faded from Vegetas and Gohans faces, as they looked at Cell, they had completely forgotton about him, now they had another fight on their hands, and Gohan was thinking it was going to be just as hard as the last.

"So which one of you pathetic insects will I be fighting today? said Cell slickly.
Vegeta and Gohan just both looked at each other and nodded, "Both of us" they said simultaneously with grins on their faces.
"But, but that's not fair, you can't both fight" said Cell, wearing a look of fear on his face.
"Why should we play fair, it's not as though you ever did, now prepare yourself fool" said Vegeta.
"Vegeta" said Gohan cautiously, "Don't take him lightly, both of us fighting is not going to guarantee a win, we have to fight this fight with our heads"
"Right, I get you Gohan" replied Vegeta.
Meanwhile Cell was looking at Vegeta funnily, this couldn't be the Vegeta he knew, taking advice from someone else, "Ohh well, what does it matter" he thought to himself, "I'll squash them both like they're nothing, I am...
But he was interrupted as Gohan threw a small blast at him, Cell, caught off guard barely had time to dodge, moving to the left just in time, but at that moment Vegeta had faded over beside him and with a two-fisted hit, he slammed Cell into Gohan awaiting knee, causing Cell to spit up some blood.
Not holding back though, Cell soon quickly regained his posture and stood up tall, and with a scream outstretched his arm and let to beams of energy fly, one and Gohan and one at Vegeta, they had not been expecting this, and were soon being driven back by the blasts, Vegeta powered up and managed to throw his blast off, but it seemed Gohan was having a little trouble, Vegeta quickly flew over and kicked the blast away.
"Wow Vegeta, you really have surpassed me" said Gohan respectfully, "Your power amazes me"
"No time for sentiments Gohan, we have a fight on our hands" said Vegeta, his gaze fixed on Cell.

And with that Vegeta lept at Cell, Gohan followed lead and flew after him, Cell braced himself as the two Saiya-jins connected with him, a shockwave was let out as Cell blocked Vegetas kick and Gohans punch, they were both stringing together punch, kick, punch, punch, blast combos, unlike anything that had been witnessed before, but Cell was blocking and dodging as though they were nothing.
"Something's wrong" Vegeta thought to himself, "He isn't tiring down one bit, we're throwing all this at him and he's not even fatigued.
Cell had noticed this momentary lapse in Vegetas concentration and punched on the chance, giving him a hard and fast punch to the face, sending him flying backwards, as Gohan looked backwards to check on Vegeta, he knew straight away he had made a big mistake, then wham, a foot had been firmly implanted in his back, sending him flying as well.
Cell took this time and powered up 2 blasts, then quickly let them go in the directions of the two warriors, they barely had time to block as the blasts hit, alot of smoke and shockwaves later, the two Saiya-jins emerged, clothes tattered, and a few grazes and cuts here and there.

Vegeta regained his pose and spat out some blood, "Are you okay Gohan?" he asked.
"Yeah, just fine and dandy" he replied, although he certainly didn't look it.
"We can't beat him in this state Gohan, we're going to have to try something else, and I know exactly the thing"
"What's that Vegeta?" asked Gohan
"Fusion"
"What! Are you serious, geez Vegeta this is a big move, do you think it will work?"
"Of course it will, we'll take a Senzu Bean each, then distract him somehow, then I'll lower my power level, and bam, we perform the dance"
"Okay then Vegeta, I trust you on this" said Gohan as he grabbed two beans from his pocket and passed one to Vegeta.

After the beans had been eaten Vegeta yelled out to Cell "Come get me you big green technique stealing freak"
Cell, enraged did exactly what Vegeta wanted, he charged at the two in fury, "NOW GOHAN!" screamed Vegeta as the two of them fired blasts at Cell then flew away, "That should keep him distracted long enough" thought Vegeta.
They landed on a flat bit of land and immediately readied themselves for the dance, Vegeta had matched his power level to Gohans, "Alright, let's do this"
"FUUUU, SIIIOOOONNNNN, HAAAA!"
There was a huge bright light as the two bodies became one, Cell watched on in fear as the warrior "Vehan" was born.
