In Dragon Ball Z fanfiction, how would a relationship between Goku and Android 21 develop?

At first, Caulifla might be a bit intimidated by Goku's power. But as they train together, she would start to understand his techniques and philosophy of fighting. Goku would also learn from Caulifla's unique approach to battles. Their relationship could evolve into a deep bond where they rely on each other in tough battles. For example, Goku could save Caulifla from a near - death situation, and in return, Caulifla could come up with a creative battle strategy that helps Goku against a difficult opponent.

Obviously, Goku and Android 18 are very popular. Goku is the main hero of the Dragon Ball series, and his power and determination make him a central figure. Android 18, with her cool demeanor and powerful abilities, also attracts a lot of attention in fanfiction.

One interesting storyline could be Goku and Android 18 teaming up to fight a new, powerful enemy that neither of them can defeat alone. They have to learn to combine their skills and powers in unique ways.

Trunks could become Goku's mentor in some aspects. Since Trunks comes from a more technologically advanced future, he could teach Goku about advanced energy - manipulation techniques that are not yet known in Goku's time. This would create a new dynamic in their relationship as Goku looks up to Trunks in this particular area while still being the overall more experienced fighter in terms of raw combat.

At first, they were just partners in the search for Dragon Balls. Bulma was attracted to Goku's unique naivete and strength in a way.

In the fanfiction, their relationship might start off as a bit of a shock to both of them. But gradually, they begin to respect each other more. Goku starts to see Bulma's intelligence and how it can benefit their family and the world. Bulma, on the other hand, comes to admire Goku's unwavering sense of justice and his strength. They communicate more often, sharing their thoughts and dreams. For example, Goku might tell Bulma about his Saiyan heritage in more detail, and Bulma might share her latest scientific ideas with Goku. This sharing helps them grow closer together.

In a fanfiction scenario, Goku and Android 21's fight could attract the attention of other Z - fighters. Vegeta, for example, might be reluctant to help Goku at first but then realizes the danger Android 21 poses to the entire planet. Goku could also try to reach out to Android 21's good side, as he has a history of trying to redeem his enemies. This could add an interesting moral dilemma to the story, whether to fight or try to save her.

Another way is that Goku could use the Spirit Bomb. He could gather energy from all living things on Earth and nearby planets. Android 21, being an artificial being, might not be able to withstand the pure energy of the Spirit Bomb. However, she could try to absorb the energy, but if Goku can overload her absorption capabilities, it would be his victory.

One possible plot could be that Android 21, with her unique powers, teams up with Goku to face a new and powerful enemy. They might have to combine their strength and fighting techniques to defeat this foe.
