If Raditz survived in fanfiction, he would likely have a complex relationship with Goku. He might start to see the value in Goku's way of life. Goku could try to reform him, and Raditz could slowly become a more positive force in the Dragon Ball Z universe.
In a straight - up power comparison, Goku has the ability to reach extremely high power levels that can destroy planets. But Naruto has the power of the Nine - Tailed Fox and his Sage of Six Paths mode which also gives him immense power. If the fight takes place in Naruto's world, Naruto could use the environment to his advantage, like summoning giant toads or using the terrain. On the other hand, if it's in a more open space like in Goku's battles, Goku could use his flight and long - range attacks more effectively. So it's hard to say who would win definitively.
Family ties are a key element. Since they are brothers, fanfictions often explore their complex relationship, like how they deal with their Saiyan nature versus the influence of Earth. For example, in some, Goku tries to make Raditz understand the importance of protecting the planet.
In this fanfiction scenario, Gine's meeting with Goku and Raditz could be filled with various emotions. Maybe Gine is overjoyed to see Goku, her long - lost son. And when it comes to Raditz, there could be a sense of family reunion despite their past differences. It could be a moment of shock and then warm acceptance as they all come to terms with their relationships.
There might be a fanfiction where Raditz survives and teams up with Goku against a new, more powerful enemy. They have to put aside their differences and learn to work together. Raditz could start to respect Goku's strength and his way of life.
One idea could be to focus on Bardock's perspective before his fateful battle. Maybe explore his thoughts about his son Goku being sent to Earth and his own impending doom. He could have some premonitions about Goku's future role in saving the universe.
In a one - on - one fight between One Punch Man (Saitama) and Goku, it's really tough to say. Saitama is known for being able to defeat any opponent with just one punch. However, Goku has a vast array of powerful forms and techniques. If Saitama landed his first punch, he'd win instantly. But Goku's speed and ability to constantly power up could potentially give him an edge. He could keep dodging Saitama's punches until he found a way to overpower him. It really depends on how the fight is set up in the fanfiction.
There's 'Goku and Raditz: A New Beginning'. This fanfiction takes an interesting turn by imagining a scenario where Raditz survives his initial encounter. It shows their journey together as they try to understand Earth and its ways, with Goku teaching Raditz about the values of the planet.
It could be a story of redemption for Raditz. He starts off as a bit of a villain, but through interactions with Bardock (either as a memory or some kind of spirit guidance) and Goku's influence, he changes his ways. They could all be training together on Planet Vegeta before its destruction, with Bardock teaching them valuable Saiyan combat techniques and life lessons that shape them into the characters we know.
