Goku might run into past versions of his friends. He could see a younger Krillin or Bulma and have some really interesting interactions. He could also meet past versions of his enemies and try to change their fates. For instance, he could meet a young Vegeta and try to steer him away from the path of evil. This would be a huge change in the Saiyan's story.
Goku's powers would be a game - changer in the MHA universe. His ability to fly would be unique among the heroes there. His Saiyan rage mode could be like an extreme version of a quirk awakening. But he might also have trouble fitting in at first. He's used to a more straightforward fight - or - be - fought world, while MHA has a lot of rules and regulations for heroes. However, his pure heart and desire to protect would surely make him a beloved hero.
Well, Goku's powers are extremely powerful. In the My Hero Academia world, his super strength, speed, and energy blasts would be off the charts. His Saiyan ability to constantly increase in power through training and near - death experiences would make him a top - tier hero. He could probably outclass even All Might in terms of raw power.
Well, Goku's powers are extremely overpowered compared to most in the MHA world. His super strength, speed, and energy blasts would be like nothing seen before. His Saiyan ability to constantly increase in power would make him a top - tier hero. For example, his Kamehameha wave could be like an ultimate move, but he'd have to tone it down to not cause too much destruction in the MHA cities.
It could be Iruka. Since Iruka is an important teacher in Konoha, he might be the first to notice Goku's arrival. He'd probably be cautious at first, not knowing what to make of this powerful being, but then try to figure out if Goku is a threat or not.
In this fanfiction scenario, Goku could meet Bulma when she was a child. He could befriend her in a different way compared to their first meeting in the original story. Also, he could run into King Kai at an earlier time and start training with him much sooner, which would significantly boost his power levels and change the course of his battles in the future.
In a fanfiction like this, perhaps Bardock is on a mission in the afterlife and it leads him to cross paths with Goku and Chi - Chi. Bardock could test Chi - Chi's strength and worthiness to be with his son. Chi - Chi would rise to the challenge, showing her determination. Goku would be in the middle, trying to make sure his father respects his wife. And in the end, Bardock could give his blessing to their relationship, seeing how happy they are together and how Chi - Chi has made Goku a better person in many ways.
They might start with a big hug. Goku would be excited to meet his father. Then they would start chatting about all kinds of things, like Goku's adventures on Earth.
Boruto's ninjutsu like the shadow clones could be used in creative ways in combination with Goku's attacks. For example, the shadow clones could distract an enemy while Goku charges up a Kamehameha. Goku's ki - based attacks could also enhance Boruto's Rasengan, perhaps by adding a ki - infused shell around it. Boruto's ability to sense chakra might be affected by Goku's intense ki, and he could learn to use it to his advantage, like sensing enemies from a greater distance.
