Disclaimer: Big Hero 6 is not mine.

Summary: The summer Tadashi Hamada went to robotics camp, his parents and his four year old brother, Hiro, go on a cruise. But the ship sinks, and his family is assumed dead. That is until, a young boy is found on a deserted island. Can Tadashi be the big brother he assumed he didn't have to be anymore? And what about Hiro? A young boy, torn from the only life he remembers. Is it possible for him to adjust to this new life? Being a big brother is hard, especially when it's just a regular kid. But Hiro isn't normal. He's a wild boy who grew up on an island, and who may or may not be a genius.

I got this idea from...you know, I don't really remember where. I got if from somewhere, I know that, but I can't recall what sparked the idea. Hope you like the story!

Chapter 1

The boy was walking around, checking for traps. He'd set up four of them before he slept, and by now, he expected to have caught something. He hoped, anyway. Food on the island wasn't scarce, but it was hard to catch. Even the fruit and edible plants were hard to find, though it got easier if you knew where to look.

His companion, a Siberian Husky, (not that he knew the name of the dog's breed) was walking along side him, sniffing the ground. The dog was old, having just been a puppy when they arrived on the island. The dog was ten years old now, but it was in good shape, and no one would even have guessed it was about seventy in human years. But it's age did show a little, evidenced by the lanky boy walking a bit slower, so the dog didn't have to force itself to go faster to keep up.

The boy himself was in great shape too, if not very big. Sure, he was skinny, after growing up on a deserted island, but he was fast, and strong. His black hair was wild, sticking up all over the place, and his eyes were lite with a brilliance that was wasted here on the island. But it was all he remembered, (save for a few fuzzy images) and for the most part, he was content.

The sound of something flying overhead interrupted his routine, but he didn't look up. It was normal for planes to go by, and boats too, but they never stopped here, and they never saw him. Now that he remembered. Planes. That was the name of those big flying things that passed by. And boats were the things that floated on water.

But this plane sounded like it was very close. Almost like it was landing. His companion seemed to think so too, for the dog stopped sniffing around for food, and looked the way the plane had gone, barking once. He put a hand on the dog's head, and when the dog looked up at him, he put a finger to his lips, signaling silence. Together, the two island dwellers crept forward, moving silently across the landscape. They passed their home, a small cave that had been dug into the side of the hill a long time ago. He didn't remember who dug it. All he remembered were countless nights spent curled up in it, with only his furry friend for warmth. He thought about crawling into it, and hiding until whatever it was that had come was gone.

But there was another part of him that was curious. After being alone for so long, he needed to see what had come to his home.

In front of them, a plane came into sight. It was making contact with the ground, wobbling like he did that time he ate the berries that were bad for him. He'd stayed in his den for almost three days, waking only when his friend poked his nose in, sniffing the boy worriedly. The plane glided across the ground for a while longer, then finally came to a rest, kicking up the dust and dirt under it.

Someone got off the planes. It was someone like him, something he hadn't seen in a very long time. Something that walked on two legs, and stood up straight.

The boy and his dog ducked in unison, hiding themselves. The dog was growling low in it's throat, and the boy put his hand back on it's head, but this time for comfort. He watched through the thicket, as someone else got out of the plane. What were they doing here? What did they want? His heart was pounding faster then that time he and his friend had had to outrun that blazing fire, which had been started by a flash in the sky tearing down on them.

The people were standing together, talking to each other. The sound of their voices drifted across the air, and reached the boy. He froze, listening hard. It had been a long time since he'd heard anyone speaking, including himself. He and his friend didn't need words to communicate. He only spoke to him if they were separated, and was calling his friend's name.

Some of the words they were speaking...he seemed to know. Every now and again, one of them would say something that he understood. They laughed, and he paused. He knew that sound, for sure. It meant they were happy. He laughed whenever his friend rolled in the mud, then the two of the them wrestled, getting the boy dirty too. Not that he minded. He enjoyed having a reason to go to the spring, which was always warm during this time of year. The colder times he spent dirty, because it was a bad idea to get into water when the air was so chilly.

He looked up at the people again, and his movement caught one of their eyes. The taller of the two looked up, and looked the boy's way. The eyes of the stranger widened.

"Hey!"The man pointed directly at him, and his friend growled. The boy knew he was spotted, and he took off running, with his friend at his heels. They tore through the trees at breakneck speeds, until they came to their den. The young boy crawled in quickly, clicking his tongue to make sure his friend would follow him in. He needn't have worried, the dog was on his heels, and they curled up together in the small space, with the dog wrapping himself around the boy protectively.

The boy breathed quietly, listening. They were approaching. They were speaking to each other.

"I swear, it was a kid!" one voice said. This voice sounded young, though older than Hiro. Not that he really knew what other humans sounded like. But he had a feeling this one was younger.

"Are you sure, sir? Might it just have been your imagination?" This one was older, for sure.

"No way, Heathcliff. It was a kid. A boy. He had black hair, and- oh!"

The voices came to a stop. They had come upon the boy's home. Instantly, he knew what they were seeing. The supplies for his traps, which he'd been working on this morning. None of his food was out there, because he wasn't dumb enough to leave it where the island animals could get to it so easily. But he'd left his supplies out, because usually the animals ignored them. He growled softly to himself, and his friend echoed him.

"Oh my. Someone seems to be living here." the older voice said. "There are clothes on the ground."

The boy had exactly two sets of clothing. He'd made them himself, out of material he'd found on the island. It had been difficult, but it was best to be wearing something when one slept on the dirt. Bugs were notorious for crawling all over him. Though perhaps leaving them on the ground kind of defeated the purpose.

"I told you. There's a boy here."

The boy held his breath as footsteps began crunching around, searching methodically. His friend was growling consistently. They were going to be found, he just knew it. He felt on the ground around him, hoping to find one of his spears. But they too, were outside, as he'd planned to go fishing after returning from his traps. He retreated further into the den, as far as he could go, his heart pounding.

"Hey, there's a hole here. Like a den! Cool!" the younger voice said, and the boy hoped he'd pass it by, afraid to look in.

But the older voice was smarter than then the younger voice, who had started to move away.

"Shouldn't we look in, sir?"

"Oh. Good idea, Heathcliff."

The boy knew he was cornered. He growled louder now, hoping to scare away the intruders, and his friend joined him. But the voice looked in, and the boy came face to face with the first human he had seen in ten years. It was a boy, older than him, with long blond hair.

"Woah." he breathed. "There's a kid in here, Heathcliff."

Another face looked in. A much older gentleman.

"So there is, Master Fred."

The boy, (Master Fred?) smiled at him, and spoke in a friendly manner.

"Hey, there. I'm Fred. This is Heathcliff. Would you like to come with us?"

There, done, got to go, I have work. Thanks for reading, hope you enjoyed.
