His father craved power but made him a slave.
In the abyss, they were opposing each other but also mutually dependent.
As the story unfolded, they gradually discovered that they were not only facing the horror of the Abyss, but also a deeper secret.

Naruto is often paired with Gaara in these fanfictions. Their strong bond in the original series makes it interesting to see how they interact when Gaara time - travels. Naruto could be the one to help Gaara adjust to a new time period or vice versa.
Often, Naruto's female characters are paired with Gaara. For example, Hinata. Since Hinata is a kind - hearted and shy character, her relationship with the initially cold - hearted Gaara could be an interesting exploration of how two different personalities come together.
Gaara's unique sand abilities and his connection to the tailed beast within him can add a lot of depth to a fanfiction. Sakura could be curious about this part of him and through her curiosity, they bond. Sakura's medical ninjutsu skills are also something to consider. Maybe Gaara gets injured and she has to use her skills to heal him, which leads to a deeper emotional connection between them as they talk during the healing process.
They're similar in their tenacity. Naruto never gives up, no matter how tough the situation is. He keeps fighting against powerful enemies like Pain or Sasuke. Gaara is the same. He has faced numerous challenges, especially when dealing with the internal and external threats to his village. Despite his past traumas, he stands firm. Also, they both understand the pain of being an outcast, which makes them empathetic towards others who are suffering.
Naruto could still be a main character. Their relationship would likely be different if Gaara were a girl. Maybe Naruto would be more protective of her.
