What makes a Dragon Ball Android 21 fanfic interesting?

In a fanfic, it could be that Android 21 has a hidden power that only Goku can unlock. As Goku helps her discover this power, they form a deep bond. This power could be related to the Dragon Balls in some way, like having the ability to control the Dragon Balls' wishes or even create new Dragon Balls.

Well, one possible fanfic could be about Android 18 and Raditz teaming up against a common enemy. Maybe they initially start off as reluctant allies, but as they fight side by side, they begin to respect each other's strength.

It probably wouldn't fit directly into the main canon as it's a rather light - hearted and comical concept. But it could exist as a side - story or an 'alternate universe' type of fanfic. It can show the characters in a more relaxed and fun - loving situation that we don't often see in the main series.

The main interesting part is the exploration of different relationships. In Dragon Ball Z, most of the focus is on the male characters and their battles. But in yuri fanfics, we get to see female characters in new lights, their friendships and possible romantic relationships.

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.

One interesting storyline could be Android 21's struggle to find her true identity. In fanfiction, she might discover that she has a hidden past or purpose that was not initially known in the original series.

There could be a fanfiction where Android 17 and 18 are sent to an alternate universe. In this universe, they have to team up with their evil counterparts to defeat a greater threat that endangers all universes. It would be a story full of action and character development as they deal with their doppelgangers.

One great Dragon Ball Android 21 fanfic is 'Android 21's Redemption'. It delves into her character, exploring her struggle between her good and evil sides. The story has some really intense fight scenes and also shows Android 21 trying to find her place in the Dragon Ball universe.

A possible plot could involve an enemy who discovers Android 18's ticklish feet and tries to use it as a distraction during a fight. However, Android 18, being the strong - willed character she is, manages to overcome this odd form of attack and turn the tables on the enemy. This would add a unique and humorous twist to the typical Dragon Ball battles.

Perhaps the fanfic could be a time - travel story. Android 21 accidentally sends Goku back in time to a point where she was first created. Goku then tries to prevent her from becoming the villain she was meant to be. This would involve Goku having to deal with the scientists who created her and convincing them to take a different path in their research, all while trying to find his way back to his own time.
