This is a one-shot fanfic as the description says, so this is the only chapter. Please review! Also, none of the characters are mine, they belong to Akira Toriyama and the Dragon Ball Franchise, etc.. etc..
The man stood in the center of the room. Blue mats beneath him, punching bags above him, all in the hope of becoming the World's Strongest. But it wasn't enough. He was too weak. Much too weak. The flashbacks came back again…
A single green, alien behemoth standing in the center of a desert. So small in comparison to the tanks, but still dwarfing them completely. With one hand outstretched, he utters a single word: "Boom." The tank explodes.
With his boxing gloves, he punches the bag harder. They're just tricks, he tells himself. He must have prepared some landmines there or something. The only problem is, he knows they're not tricks. The flashbacks come again…
A man with black hair, a sleeve-less orange gi and orange pants, and blue boots and a belt… Before him stands a man with spiky black hair, a tail, and an unearthly blue and white suit of armor. They begin to fight, their power felt throughout the whole world. Punch by punch, blow by blow, kick by kick, new craters are formed, and the dangling threat of a world-destroying catastrophe is always lingering during the battle.
Stronger, he grunts as he punches the punching bag again. He still knows that is useless. He still wonders why he is going to fight the monster Cell. Because no one else can, he tells himself.
An arrogant, shallow, boastful man. All of this is as he acts, so he can be known as the World's Strongest on TV, and on newspapers. He has won the World Tournament several times, but he wonders what it counts for. He can fight regular martial artists, but not the superhuman martial artists who can fly, who can shoot energy out of their palms, who can destroy planets. Ultimately, he is intimidated and humbled by the other mysterious demigods he has seen before: the short bald one with six dots on his head. The tall one with three eyes. The man with a scarred face and spiky black hair. The green man with antennae. The young boy with spiky black hair. The older man with spiky black hair. And strongest of them all, the only one he knows by name, the one known by the name Son Goku. The man who battled Piccolo Daimao, and is believed to have went against the aliens who appeared on Earth years ago.
He must become stronger, and he must go against the monster who is Cell. "Can I do it?" he asks himself. He pauses in hitting his punching bag. For a second, the entire world seems to collapse under him. The revelation hits him like the ground hitting him after falling out of the sky. He comes to a heartbreaking answer. No.
As he stares at the punching bag, he thinks. Not in this state. But if I train harder, I will become the world's strongest. I will defeat Cell. He punches the bag again.
The man stands humbled before the monster Cell, the monster who had created a tournament to see if anyone can defeat him, and if no one does, then everyone pays the ultimate price: the destruction of the world. He sees them all, the group of ultra-powerful humans and non-humans just as he predicted, ready to go against the monster as well. The demonic Cell has a smile on his face. He steps forward, before anyone else has a chance to. On the ring, before a god, he stands, prepared to risk his life, while having to show the bluff that he is completely confident. He takes on his fighting pose. He puts on a smile for a camera, but the monster can see the determination, and fear within him. Showing no empathy, he takes pleasure in this. He is Hercule Satan, World's Strongest.
