what if goku wished for immortality

It could lead to all kinds of interesting plot twists. Maybe they come back stronger or with new abilities.

Hard to say exactly. Maybe she got a taste of the delinquent life and realized it wasn't all she thought it would be. Or perhaps she ended up finding a better path. The possibilities are endless!

If Planet Vegeta was wished back, it would likely bring back old enemies and allies. The Saiyans might have to deal with the consequences of their past actions and find a way to coexist peacefully or else face more destruction.

I have no idea. It's a rather odd and confusing statement.

Love and family are likely main themes. Adoption is about creating a family through love, not just biology.

The main theme could be about complex relationships. It might explore themes like hatred, revenge or the extreme emotions that lead a character to wish someone dead.

Sure! There are many stories that feature this concept. It often involves some kind of supernatural or magical element that grants the wish to bring the son back to life. Different stories handle it in different ways, but the basic idea is present in quite a few.

One possible plot could be that the Dragon Balls are gathered in the future, perhaps by Goku or his descendants. Bardock is then wished back to life. He has to adjust to the new world, which is very different from the one he left. He might be in awe of Goku's power and the fact that his son has saved the universe multiple times.

The story of the king who wished to marry his daughter is typically a dark and twisted one. It might showcase the king's selfishness and the daughter's struggle to escape this bizarre situation. It could also bring in elements of court intrigue and external forces trying to stop the king.

Well, it could be about Goku Jr learning some of Goku's most powerful moves. Maybe Goku teaches him the Kamehameha. They might also go on an adventure together, like fighting a new and powerful enemy that neither could face alone.
