Goku would probably be really confused. He loves Chi - Chi and their family, and he might not understand why Bulma would want to break them up. He might just tell Bulma straight that he's happy with his life as it is. Chi - Chi, on the other hand, would be furious. She's very protective of her family and her relationship with Goku, and she'd likely give Bulma a piece of her mind.
It's debatable. There are many strong fictional characters, and it depends on various factors like powers, abilities, and the context of their stories.
The person who is telling the story is often called the narrator. It could be the main character in a first - person narrative, sharing their own experiences directly. For example, in 'The Catcher in the Rye', Holden Caulfield is the narrator, and we see the story unfold through his eyes.
I think Zeno would be a really tough opponent. Zeno has the power to erase entire universes, and a Goku and Goku Black fusion, despite being extremely powerful, would have a hard time against such a being with god - like powers.
Goku's ultimate form in the manga is Ultra Instinct. This state grants him enhanced combat abilities and reflexes. It's a breakthrough that showcases his potential and is a key factor in his toughest battles.
In a more detailed story, the wife's reluctance could be the central conflict. She might start to question the husband's understanding of their relationship. She could worry about the implications on their marriage, such as the potential for jealousy, loss of trust, and the breakdown of the emotional bond they have. Her reluctance could also make her withdraw from the husband emotionally as she feels that he is suggesting something that is completely against her values and what she thought they had in their relationship.
One possible plot could be that Bulma might be jealous of the relationship Goku and Chi - Chi have. Maybe she sees how much Goku has changed since being with Chi - Chi and she misses the old, carefree Goku. So, she tries to create misunderstandings between them by, for example, making it seem like Goku is more interested in training with her than spending time with Chi - Chi.
It's really hard to say. Goku has the power to destroy planets and reach incredible levels of strength with his Super Saiyan forms. However, Naruto has the power of the tailed beasts and his own sage mode which gives him a huge boost in power. And Sonic, while he may not have the raw power like the other two in terms of destruction, his speed is so great that he could potentially outmaneuver both of them. So it really depends on the situation and how the author writes it.
Well, without more context, it's hard to say exactly who she is. She could be a rival of the person. For instance, in a workplace cafeteria, if there is a promotion at stake and the food somehow represents success or a reward, she might be a coworker who wants to undermine the other person.
