goku's tail grows back

It could also be a symbol of a new power - up. In the Dragon Ball series, new physical changes often lead to increased power. So, getting his tail back might mean that Goku is about to reach a new level of strength. Maybe he'll be able to transform into a new form that is related to his Saiyan heritage and the presence of the tail. This could give him an edge in future battles against stronger opponents.

He might be surprised at first. After all, having his tail back is a big change. He could start to explore the new sensations and abilities that come with it, like better balance perhaps.

In the Dragon Ball universe, there are many strange and wonderful things. King Kai might have access to some rare or magical items. He could use one of these items to help Goku's tail grow back. For example, there could be a special fruit on his planet that has regenerative properties. When Goku consumes it or King Kai uses it in some other way, it triggers the growth of the tail.

In some fanfictions, it might grow back due to magical or alien forces. For example, a powerful wizard in the fanfic universe could use a spell to regrow it. Another way could be through some sort of advanced medical technology created by the Saiyans or their allies.

One scenario could be that Goku enters a special realm where time and space work differently. In this realm, the laws of biology are altered, and his tail simply regrows. Another might be that an enemy's attack, instead of harming him further, accidentally triggers a hidden regenerative ability in Goku that causes the tail to grow back.

Goku might become more in touch with his Saiyan heritage. His tail was a part of what made him a Saiyan originally, so getting it back could make him more aware of his roots. He could become more aggressive in battle, like how Saiyans are known to be.

In a fanfiction scenario where Goku gets his tail back, it might be due to a genetic experiment gone right. Some scientist in the Dragon Ball world, either good or bad, might be working on Saiyan genetics. They accidentally (or on purpose) trigger the regrowth of Goku's tail. Once he has his tail back, it could change his relationship with other characters. His son Gohan might be really interested in his dad having a tail again. Also, Goku could use his tail in combat in new and unexpected ways, like using it to grapple opponents from a distance or as a distraction during a fight.

Erza would also be a good pairing. She is a very disciplined and strong - willed character. Goku could learn from her discipline, and she could learn from Goku's carefree yet determined attitude. They could fight side by side in battles and protect each other.

Well, perhaps Percy is a character in a magical world. He could have been cursed or exposed to some strange magic that causes him to grow a tail. Maybe it starts as a small, furry growth that he tries to hide, but as the story progresses, the tail takes on a life of its own and gives him unique abilities like climbing better or sensing danger.

One possible plot could be that Naruto's new tail gives him unique abilities related to balance and agility, like a real fox. He might have to learn to control it at first, causing some comical situations in the Hidden Leaf Village. Maybe he could use it as an extra limb in battle, grabbing kunai or shuriken that he couldn't reach otherwise.
