I OWN Nothing all of the characters and their origins belong to Dragonball Z and DC Comics

A/N This is my first story, I am open to constructive criticism to make this story better, many minds are better than one. I have taken some creative liberties, being that it is fanfiction. One such liberty, Chi-Chi is dead, murdered by the androids, this is an important part of the story. I feel that these are some of the best characters in DBZ and they did not get enough airtime. There will be some lemons/ pairings when the two heroes arrive in the DC Universe which will be based on the N52. Please submit in either a PM or a comment some suggestions for ladies that these heroes can get with. Well, here goes, Enjoy the History of Heroes an adaptation of the History of Trunks.

Chapter 1 The Key to Victory

Our heroes, Trunks and Gohan have been fighting the androids 17 and 18 for several years. All hope seemed lost until they found an old notebook on a routine part search.

Trunks, a tall and extremely muscular 13 year old boy was flying at a low speed and low to the ground. He was scanning the ground looking for parts that would help his mother with her machine. Bulma the genius daughter of Capsule Corps was trying her luck at a brand new invention, one that would put all of her ingenuity to the test, a time machine. She had told Trunks that going back in time to save Goku from the deadly heart disease and bringing back Vegeta would be the key to defeating the evil androids that had already destroyed so much of the Earth and taken so many human lives. The 13 year old boy was the son of Vegeta and wanted more than anything to be strong and brave like his father. He was not alone though, he was aided by the son of the legendary Goku. Gohan was a 22 year old man who had seen far more than he ever should have. He had fought Raditz, Vegeta, been trained by Piccolo, traveled to Namek and fought with Frieza, and Now he was engaged in a seemingly endless war with the Androids. He had seen countless people die including his own father, twice. Once to a Special Beam Cannon launched by Piccolo and again, unfairly, to a heart disease. He was the last of the Z-Fighters after watching all of them fall to the power of the androids, including his own teacher Piccolo. He had scars that covered his entire body and muscles that have been developed through constant battle. Gohan has mastered his father's legendary Super Saiyan transformation, but it hadn't been enough to defeat the androids or enough to save his right arm. His arm had been severely damaged beyond repair to a blast launched by Android 17, but he was still a force to be reckoned with. The two half saiyan half human hybrids flew in Orange City looking for technology that would save their world. He was normally talkative with his student, Trunks, but today he had a secret. A secret he knew would completely destroy the dynamic of their relationship, possibly permanently, when he told him. If they lived long enough. Trunks took notice of his master's unusual demeanor.

"Hey Gohan, remember that time when I almost transformed?" He said with a smile that read hope, "Those androids won't stand a chance when I can pull it off! Two super saiyans will be too much for them to handle. We should be training."

Gohan replied, "Yeah, don't worry buddy. We'll get em, we have to get them. Look there! It's Krillin's old gym." After Goku died, the Z-Fighters unofficially disbanded until the androids showed up. Krillin became a martial arts instructor in Orange City to keep the bills paid. Considering the fact that he was the strongest human in the world, he was more than qualified to teach the various martial arts to aspiring students. Obviously, neglecting to teach the intricacies of ki powers. "Come on, Gohan." Said the teenager, "Let's spar for a round."

"We have things to do Trunks," the teacher responded.

"Dude we have been looking for parts all week, we really should stay sharp in case the androids show up."

"And your way of doing that is to trap ourselves in a building and fight until we're tired," Gohan was always good with reasoning.

"Please, I promise it'll be quick and then we can keep scrap hunting!" The saiyan teenager had an unmatched persistence, that even Gohan admired.

"Fine! Let's land and go inside the Dojo," he acquiesced. The two saiyans landed right in front of the gym that had clearly seen better days. The surface of the building was covered in vines and cracks in the exterior. The sign that once proudly illuminated "Kame House, The Dojo of Krillin San" was missing half of it's letters and all of its shine. Gohan immediately felt depression and unease float over him, gazing upon the training gym of a long gone friend. Gohan paused to think of all the good times he had with Krillin, traveling to Namek and hunting dragonballs. He sighed as he and Trunks pushed open the doors to the Dojo. The inside was still in pretty good shape considering the circumstances. As Trunks open the door, bugs begin to scatter, it had been quite a long time since light entered this place. There were pictures of Krillin and various students, smiling as they had once been happy. There were black belts hanging on the walls, they represented Krillin's various qualifications in the martial arts. In the back over Krillin's office, there was a picture of him and Master Roshi and Gohan's father when they were children.

"I'm sorry, Master. We'll make those bastards pay for this," Trunks said noting the grim look on his teacher's face.

"You're right, lets train." The two warriors walked to the middle of the gym floor and took fighting stances, looking at each other with intensity. "Here are the rules," Gohan stated "No flying or Ki beams. We don't want to attract the androids. Melee attacks only, first one out of the ring loses."

"Deal!" The teenage saiyan said enthusiastically, he had been mentally preparing for a rematch with his master. Suddenly, Gohan's aura spiked to a golden yellow and his hair turned blonde, standing straight up.

"No fair, I can't go super saiyan!" Trunks exclaimed.

"Battle isn't fair Trunks," the calm Gohan replied. "Right now the androids are stronger than you, the same way that I am stronger than you. You'll never reach new heights if you don't push your limits."

"Ok Master Gohan," Trunks said, still nervous about the upcoming challenge. He got into a fighting stance that mimicked his master and launched at full speed towards Gohan. He threw his fastest plan strikes and Gohan blocked them with ease, redirecting all of Trunks' energy. "You're not focused Trunks, the objective is to get me out of the ring, not swing wildly." At this, Trunks threw in a leg sweep, that Gohan easily predicted as he leapt over Trunks and landed in the middle of the gym floor. "You're too predictable, you have to switch things up," Gohan coached. Trunks grunted with frustration and launched at the older saiyan again, he threw a left hook and a right, then a spinning kick all of which Gohan dodged expertly. Trunks then threw a haymaker which narrowly missed Gohan's face, and then a knee-kick which nearly connected, but Gohan blocked it with his left hand. "Come on," he egged, "remember I only have one usable arm." Trunks was giving it his all, but Gohan's super saiyan speed was proving to be too much. Trunks, refusing to be bested launches another ferocious combo at Gohan, actually catching him in the face. He paused very briefly to celebrate and that was all it took. Gohan fazed out, appeared on the side of Trunks and delivered a kick to his midsection sending him flying from the ring. Trunks smashed into the door that blocked entry into Krillin's office and into the room. Hitting the shelves that once held Krillin's work, the shelves began to crumble under the impact of the saiyan. Trunks was covered in books that detailed Martial Arts techniques and pictures of the Z-Fighters that Krillin used to reminisce about better times. "Fuck! I lost again," Trunks shouted in frustration, punching the ground. Gohan powered down as he approached his student to help him up. "It's okay buddy, I've had much more experience than you. You're getting better." Then something caught his eye, a book laid out on Trunks's chest was called "Secrets of the Earth" and it was bookmarked to page. Gohan picked it up and opened to the page, there was a passage that was highlighted. Gohan guessed that his late friend Krillin had read this before he was killed. The passage read, "On Kami's Lookout, high above the Earth there is a room that will only allow the greatest of martial artists inside. Only the fiercest of warriors can survive a day in the Hyperbolic Time Chamber. One day in the chamber is the same as a year of training on Earth. People who survive, can grow tremendously."

Gohan's eyes welled with amazement and excitement as he read the passage. Trunks now on his feet looked at his master with confusion, "What is it?" He asked.

"It's Hope," Gohan replied optimistically.
