In the peaceful hills of Mount Paozu, a young boy with a tail named Goku lives alone. Raised in isolation after the passing of his adoptive grandfather, Goku has developed incredible strength and agility, though he's blissfully unaware of his own unique nature. He spends his days training, hunting, and exploring the beautiful wilderness, always eager for the next adventure.One morning, as he roams the forest gathering firewood, a loud rumbling echoes from above. Goku stops, looking up to see a strange, shiny object hurtling through the sky. It's a car—unlike anything he's ever seen—speeding toward him, bouncing off rocks and swerving through the trees. Instinctively, Goku leaps out of the way as the car crashes and skids to a halt in the clearing beside him.
Emerging from the wrecked car is a young girl with blue hair, looking both shocked and annoyed. Bulma, a genius inventor from the city, dusts herself off and checks her capsule car for damage."Hey, kid! You almost made me crash!" Bulma exclaims, though she's more surprised than angry. She's never seen a boy with a tail before.Unfazed, Goku tilts his head curiously. "What kind of monster is this thing? I've never seen one like it!""It's not a monster, it's a car!" Bulma scoffs. She's used to people knowing what technology is, but Mount Paozu is more rural than she expected. "And anyway, I'm looking for something important, not sightseeing.""What are you looking for?" Goku asks, eyes gleaming with curiosity. Bulma pulls a shiny, orange sphere from her pocket. "Ever heard of a Dragon Ball?"Goku's eyes widen. "Hey, I've got one of those at home!" He's never thought much about the odd, four-star ball his grandpa gave him, but this strange girl seems very interested in it.Thrilled, Bulma explains her quest: she's searching for all seven Dragon Balls, legendary objects that, when gathered together, can summon a mystical dragon who will grant any one wish. She persuades Goku to let her see his Dragon Ball, and, in return, offers to let him come along on her journey.
Curious and excited, Goku leads Bulma to his home, where he shows her the four-star Dragon Ball. Bulma's ecstatic, knowing she's one step closer to her wish. "What are you going to wish for, anyway?" Goku asks.Bulma blushes slightly, brushing it off. "It's a secret," she says, not ready to admit that her wish is for the perfect boyfriend. Seeing her enthusiasm and realizing this could be the adventure he's been waiting for, Goku agrees to join her. They pack a few essentials and set off down the mountain. Goku marvels at the strange inventions Bulma has brought with her: capsules that turn into vehicles and gadgets he's never seen before. The two are an unlikely pair—Goku's strength and naivety contrasting with Bulma's intelligence and worldliness.
Their journey is hardly easy. The wilderness is full of dangers, but Goku's incredible strength keeps them safe. They encounter wild animals and even bandits, whom Goku easily scares off. Bulma begins to realize that Goku is far stronger than any kid she's ever met, and she starts to wonder if there's more to his story.As they travel, they come across a stranded sea turtle. The poor creature, having wandered far from the ocean, is exhausted and unable to find its way back.Goku, moved by the turtle's plight, offers to carry it to the shore. Bulma, skeptical, tries to convince him that helping the turtle isn't worth the effort. "Come on, it's not like it's going to pay us back or anything!" she complains.But Goku insists, hoisting the turtle onto his back and setting off with determination. Bulma sighs but tags along, and as they make their way to the coast, she begins to realize that Goku has a kind heart, and perhaps this journey won't be as boring as she thought.
When they finally reach the shore and bid farewell to the turtle, something extraordinary happens. Just as they're about to leave, a blue blur appears, speeding toward them across the beach at an impossible speed."Whoa!" Goku exclaims, his eyes sparkling with excitement. "What's that?!"The blur skids to a stop, revealing a spiky-haired, blue-furred hedgehog on two legs. Sonic the Hedgehog grins, striking a pose. "Hey, thanks for helping my buddy here!" he says, nodding to the turtle.Sonic, born on Earth with unique abilities, has been journeying across the land, meeting new people and looking for adventure. Seeing Goku's kindness and Bulma's curiosity, Sonic is instantly intrigued."Name's Sonic," he says, extending a hand to Goku. "What's your story?""I'm Goku!" the boy replies enthusiastically, shaking Sonic's hand. "I'm looking for Dragon Balls with Bulma here."The mention of Dragon Balls piques Sonic's interest. "Sounds like my kind of quest!" he says with a wink. "Mind if I tag along?"Though Bulma hesitates, Goku is thrilled. The three of them quickly bond, each fascinated by the others' unique abilities. With a new teammate, their adventure truly begins, now filled with even more potential for excitement, danger, and discovery.
