Goku had never realized that he wasn't Human.
Different, yes, but not foreign.
The tail had just been another part of his body, a natural appendage that just happened to connect to his spine. Something that could be used, worked like a muscle, for everyday life. Catching fish was only one of the ways he could name as to why he loved his tail.
The amount of food he could in-take at any given time was necessity. Everyone needed food to survive, he just happened to eat a little more than most people.
The need to fight, for it was a need, was like breathing for him. He could not live without fighting, without seeing how far he could push his body. He needed to find out if he was stronger than every opponent that presented himself. There were no exceptions.
So he lived the only way he knew how. He grew, he created a family, and never once did he think he was abnormal.
Then, his brother had decided to pay him a visit.
And somewhere inside himself he had known he was kin to this man before any words had been spoken. This man, this being, was like himself.
Just exactly how he knew this he could not say. Raditz's mere presence had struck a chord that rang down to his very core and made him feel a sense of familiarity. But his brother had not come to make peace. And suddenly, his life was in chaos. His childlike innocence crushed as reality was forced upon him.
He was Human no more.
There was a name for all of those small differences, those quirky mannerisms that he had never recognized as peculiar to those around him.
Alien.
Saiyan.
His mind refused to accept it even as his spirit acknowledged it as truth.
He was not of the Earth. Not of the planet that he called his home; that he protected with every breath in his body. Not of the home he loved so much. His world crashed and the two brothers fought mightily.
Neither succeeded; death took them both even as more of his kind came hurtling towards them.
In death he was given a goal, reasoning behind all of the questions that had turned his mind to mush and had caused him to lose the fight with Raditz. In death, he came to reconcile who and what he was. He came to understand himself just a little bit more.
And it was in death that he found a way to put his world back together.
