One week has passed since Trunks travelled through time to warn the Z Warriors about the cyborg attack that would happen in three years time. Goku decided to train with Gohan and Piccolo. Vegeta rushed to Capsule Corp. to get Dr. Briefs to build a ship that could create gravity four hundred times that of Earth's. Of course Dr. Briefs called Vegeta crazy, but couldn't convince him to withdraw the request so he built it for the demanding Prince. Shortly after completion, Vegeta retreated to the comforts of outer space to train alone. Meanwhile, Krillin decided to train on Master Roshi's island but the perverted hermit wanted to watch exercise videos all day. It was going to be a long three years for Krillin and Master Roshi.

That brings the story to the forests under Kami's Lookout. Tien and Yamcha were going to begin their intense training today. Yamcha strolled into a clearing in the sea of trees. He was wearing his familiar orange gi with the Turtle school insignia emblazoned on the front and back of his shirt. Tien was wearing green pants, black boots, and a white under shirt. Tien was in deep meditation when Yamcha approached him.

"Ahh you're finally here Yamcha." Tien said casually breaking his meditation. "How did Bulma take the news of you leaving for three years?" Tien questioned his training partner.

"Well let's just say she told me never to come back." Yamcha sadly sulked as the words came from his mouth. Tien looked puzzled at the statement and changed the subject of the conversation.

"I'm sorry to hear that buddy. Well I think it's time for our first session. In order for fusion to work, our power levels have to be exactly the same. I could lower my power to your level, but that wouldn't make the fusion very strong if it were to work." Tien explained to Yamcha. "For the next few months we're going to spar until your power is somewhere close to mine. The goal is to not only increase your brute force, but hone your other fighting techniques as well." again Tien stated to Yamcha.

Yamcha began to raise his power level to his maximum, and the trees began to shake furiously. Tien let a wry smile cross his face as he also began to power up tremendously. The two warriors were covered in white auras and caused panic in the wild life. A flock of birds scattered immediately when the two began to fight with one another. Yamcha rushed forward with his right fist towards Tien's face, but the three eyed warrior side stepped Yamcha and delivered a crushing kick to his side. The kick sent Yamcha flying through a row of trees. He got up relatively unscathed besides a few cuts on his arms and face.

Tien then rushed Yamcha looking to connect with a blow to the chest, when Yamcha phased behind Tien and delivered an axe handle strike to Tien's back that sent him crashing to the ground. After sizing each other's abilities up, Tien and Yamcha then proceeded to get serious. They couldn't afford to go easy on each other, so this had to be a fight nearly to the death. Yamcha was a lot stronger than Tien thought he was, but Tien was holding back almost half of his power to give his friend a good fight.

"Alright Tien, let's take this up a notch. KAAAA-MEEEEE-HAAAAAAA-MEEEEEE-HAAAAAAAA!" Yamcha screamed as he launched a blue energy wave at the triclops.

"Finally, time for some fun Yamcha! Tri-Beam, fire!" Tien roared back as he brought his hands to a triangle formation and launched an equally sized yellow ki wave. The attacks collided with such force trees were launched into the far off ocean. Neither fighter would give in to the other's attack. Tien was forced to increase his energy even more to push Yamcha's Kamehameha wave back enough to cause a massive explosion in the forest.

The explosion uprooted more trees and dirt. The thick brown dust was enough to choke the average human, but Tien and Yamcha could easily withstand the smoke. When all was clear Yamcha and Tien were still standing. Both fighters breathed heavily as the cuts and bruises became almost too much torture to withstand. Despite being around sixty percent of Tien's power level, Yamcha managed to deliver a significant amount of damage to the stronger fighter. Tien saw that Yamcha was laboring began to fire a volley of Dodon Waves his way. However, Yamcha was too tired to dodge most of the ki assault and raised his arms to block the brunt of the attacks.

"Damn Tien is strong, but I still have one more trick up my sleeve." Yamcha thought to himself as he stood up and raised his power once more. Yamcha began to hold his right arm out and concentrate all of his remaining power into his hand. Soon a yellow ball emerged from his outstretched limb. "Spirit Ball attack!" Yamcha screamed as he threw the ball at Tien. Tien phased away from the incoming ki attack, but it kept following him like a homing missle. "You're not the only one who was honing their techniques while you were away. This attack will follow you until you get smashed by it." Yamcha declared as Tien flew away in the opposite direction.

Tien then had the idea to fly towards Yamcha, and phase away at the last second to have it hit him instead. He started flying even faster towards Yamcha, but that idea had already crossed Yamcha's mind. When Tien had him in his sights he was horrified to see another Kamehameha wave heading towards him. Yamcha had successfully outsmarted Tien, and the three eyed warrior got hit by both attacks with such force he was sent crashing towards the ground. Tien landed with a hard thud as Yamcha rushed to his aid.

"Tien, are you alright?" Yamcha questioned as he shook Tien back to conciousness.

"Yeah, I'll be alright. You sure are crafty Yamcha. I underestimated your abilities greatly. I thought the difference in our power would be enough to overwhelm you, but you just kept coming back with another strategy." Tien complimented his longtime friend. The two would have many more battles over the next couple of months. The two fighters' strength increased exponentially while training with each other. The two were almost near equal in power and mind when the next phase of their training was set to begin.

"Alright Yamcha, we have grown strong together, but now it's time to become one being. The fusion technique is certainly an odd technique. First I'll go over the limits of the form. If this works correctly, fusion will last half an hour. At the end of that half hour, our bodies will separate and be unable to attempt the technique for at least an hour." Tien carefully explained to the scarred warrior. Yamcha nodded and let Tien begin explaining the execution of the technique. "Alright we have to stand three steps apart. The second move is for us to mirror each other's movements. I'll be on the left and point my two arms to the left. Take three steps towards you while shifting my arms with two pointer figures aiming to touch your fingers." Tien explained to Yamcha while doing the required moves of the dance. Yamcha started to laugh hysterically at the routine Tien just demonstrated.

"You brought me out here to teach me that ridiculous dance?" Yamcha questioned.

"I know it's strange, but can you at least try it before you judge?" Tien strongly retorted back.

"Alright Tien, I'll try the technique. If it doesn't work I'm going back to West City though. Got it?" Yamcha defiantly said. Tien nodded and they began to attempt the fusion. Tien and Yamcha synchronized their power levels. "So three steps apart right?" Yamcha asked. Tien nodded and they began the dance. Yamcha raised his arms to his right side. Taking three steps forward Tien who mirrored his comrades movements. "Fuuuuuu" Both warriors said in harmony. When the two warriors approached each other they raised their knees while saying, "ssssiiooonnnn. Haaaa!" As their pointer fingers touched in perfect harmony the duo were bathed in a white light that took over the forest.

The wind kicked up to gale force levels through the forest. Tien and Yamcha were no longer individuals. The warrior that was left was dressed in an odd outfit. This new warrior had Yamcha's long hair and facial scars, while retaining Tien's third eye and chest scar. They were also wearing white baggy pants with a green sash, green socks, black shoes, and a green vest with yellow padding around the neck and shoulders.

"I am Tiencha! With our new combined power we will show those cyborgs what the power of humans can accomplish!" Tiencha roared as he began to raise his power level. The newly born fusion warrior was easily ten times stronger than Tien and Yamcha combined. However, they would still be little match for Goku in his Super Saiyan form. "How can we close the gap between this form and Goku's Super Saiyan form?" Tiencha questioned himself.

Suddenly, Tiencha felt the presence of someone trying to enter his mind. "Hello? Tiencha, I see the fusion technique that you witnessed on Grand Kai's planet was successful." The mystery voice said to the fused being.

"Who is trying to talk to me? King Kai, is that you?" he questioned aloud.

"Yes, it is King Kai. I was observing you from my planet and had an idea for you to try during your training. Try using the Kaioken technique that I taught the two of you while you were training with me. Normally, it can't be used for extended periods of time unless you're strong like Goku. However, I think the strain of the power can be handled by the fusion technique. Perhaps you can grow your power beyond that of Goku's." King Kai explained. "Good luck to you both, and show the monsters your strength when they arrive." King Kai said before closing the mental link.

The conversation Tiencha had with King Kai caused the fusion to end before they had the chance to attempt the suggestion. Tien and Yamcha were separate beings once again, and looked forward to the rest of their training. "So, do you believe in the fusion now Yamcha?" Tien joyfully questioned as he put his arm around his friend. Yamcha grumbled under his breath and told Tien they better find some food before the sun went down for the day.

Two years have passed since that fateful encounter with the boy from the future. Tien and Yamcha were training ferociously to master the art of fusion. Meanwhile on Mount Paozu, Goku and Piccolo were deep in a sparring battle before sunrise. The purpose of their training was to have Piccolo become as strong as Goku's Super Saiyan powers. Piccolo was progressing very nicely, being able to match Goku at his power level when he fought Freeza on planet Namek. Gohan was studying at home while his father and mentor were battling in the mountains. The young scholar found it hard to concentrate on his books when he could sense what was taking place in the distance. Gohan was lucky he was allowed to train at all, as Goku had to make a deal with Chi-Chi. The deal was Gohan could train in the afternoon until dinner, provided he finished all of his homework first.

The training Gohan was getting from the two powerful warriors was enough to have doubled his strength from when he was fighting in outer space. All of a sudden, Gohan sensed his father and Piccolo's power level drop almost down to nothing. This worried Gohan, as they never suppressed themselves to this degree. Gohan went to rush out of the house and to their aid, when his mother suddenly walked into his room with breakfast for her son.

"Gohan what on Earth are you doing?" Chi-Chi asked while snapping her voice.

"Mr. Piccolo and daddy's power is almost down to nothing mom! I hope they didn't kill each other, I have to go check on them!" Gohan roared back as he opened his window ready to fly off at jet like speeds.

"Oh no you don't Gohan! You're staying right here." his mother forcefully demanded. "Besides, I'm sure they just tired each other out. Have some faith in your father Gohan. Now eat your breakfast and finish your work so you can go outside." Chi-Chi lovingly instructed her son.

"Okay, mom. I'll finish this up." Gohan agreed finally.

"That was a nice battle Piccolo! I've never had to drop my power this low after a fight in a very long time." Goku complimented the green warrior.

"I hope we didn't worry Gohan though. I'm sure he's awake by now and could sense our fight. You know how your wife likes to wake him up early to do homework." Piccolo joked back chuckling with his once arch rival.

"Yeah, Chi-Chi sure is tough on the kid. I don't blame her though, I wouldn't want Gohan to grow up like I did. He's far smarter than I am. I looked at his homework one day and it gave me a migraine." Goku laughed as he stood up. "Let's go get take a break and get some food. Do you like fish Piccolo?" Goku asked of his training partner. Piccolo grumbled at the thought of eating another fish meal with Goku and his family. That's all they have eaten for the last month straight. Despite telling Goku numerous times he doesn't like fish, Goku kept asking anyway.

"Hey, Goku. Do you think we stand a chance against the cyborgs Trunks warned us about?" Piccolo questioned Goku who was looking for fish in a nearby lake.

"Well Piccolo, to be honest I'm not sure. Our powers have gotten stronger, but I always think what if all the training we do isn't enough." Goku stated back as he plucked a massive fish from the clear blue waters.

"I'm also concerned about the Heart Virus you were warned about. Have you taken the medicine to prevent yourself from getting sick?" Piccolo questioned.

"Piccolo I feel fine right now. Maybe I won't get sick after all. But if I start feeling off, I'll take the medicine." Goku reassured the worried Namek. "Let's go back and cook this delicious fish for lunch. I hope Chi-Chi likes that we brought home food." Goku said with a laugh. The two training partners then flew away towards Goku's house.

Meanwhile in the deep recesses of outer space, the Saiyan prince Vegeta continued his training under four hundred times Earth's gravity. Vegeta has not yet figured out how to transform into a Super Saiyan. "Damn you Kakarot! Why can't I transform? It's supposed to be my birthright!" Vegeta shouted at the top of his lungs from inside his ship. No matter how strong Vegeta became, he would never surpass Goku without the ability to become a Super Saiyan. Vegeta then decided to head back to Earth for a few months. The monsters were predicted to appear one year from May 12. Vegeta did need to refuel his ship after all, or be stuck in outer space forever.

While most of the other Z Fighters were gaining massive amounts of power, Krillin seemed like he wasn't progressing at all. "Master Roshi, two years have gone by and I barely learned anything!" Krillin yelled at the old hermit. Master Roshi paid little attention to Krillin and kept his eyes on the television set.

"Krillin, you're interrupting my work out!" Master Roshi yelled back at Krillin. Master Roshi of course wasn't working out but staring at the woman doing aerobics on television. These "workouts" have been a common occurrence for Krillin the past two years. He needed to do something drastic to improve. Krillin snuck through Master Roshi's closet and found an old turtle shell. Krillin put the shell on his back, walked out the back door of Kame House, and flew off to parts unknown to train for his final year.
