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 it's a fan - created scenario where Android 18 has a bet with someone, like Krillin, that she's not ticklish on her feet. Then the story revolves around the attempts to tickle her and her reactions. It could show a different, more vulnerable side of Android 18 while still maintaining the fun and adventurous spirit of the Dragon Ball universe.
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.
It could be about a trainer named Mina who has a unique bond with her Pokemon. Maybe during a rest in the Pokemon journey, her Pokemon accidentally tickles her feet, leading to a light - hearted and funny moment that strengthens their relationship.
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.
It could also be a fanfic centered around their friendship. Android 18 might initially be cold towards Bulma, but as time goes on, they start to bond. Bulma could introduce Android 18 to the joys of normal life, like shopping or going to the beach. And Android 18 could protect Bulma from threats that her scientific work sometimes attracts. In the end, they become inseparable friends, changing the way the other characters view Android 18.
A Dragon Ball Android 21 fanfic is interesting when it adds something new to the existing lore. Maybe it gives a new origin story for Android 21 that ties in with the overall Dragon Ball mythology in a creative way. It could also explore her place in the universe from a different perspective, like how she might view the Saiyans' obsession with power or how she could use her scientific knowledge in ways that the original story didn't. Additionally, a good fanfic will have well - written dialogue that really captures the essence of the characters, especially Android 21's internal conflict and her external interactions.
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.
A rather interesting fanfic has Piccolo being tickled by Dende in an attempt to cheer him up. This is unique because it shows the relationship between the Namekian characters in a new light. The tickling serves as a way to break the stoic nature of Piccolo and also highlights the innocence and kindness of Dende.
Well, in a fanfic, Kid Goku and Android 18 could have an interesting dynamic. Kid Goku is pure - hearted and always eager for a good fight. Android 18, on the other hand, is tough and has her own sense of justice. Their interaction might start with a misunderstanding. Maybe Goku mistakes 18 for a bad guy at first because she's an android. But then, as they get to know each other, they could end up teaming up against a common enemy. Goku would be impressed by 18's strength, and 18 might be a bit amused by Goku's naivete.
Well, it could be about a trainer having a light - hearted moment with their Pokemon. Maybe the Pokemon is feeling a bit down, and the trainer discovers that tickling its feet makes it laugh and cheer up. It could also involve different Pokemon species and how they each react to having their feet tickled, like some might be more ticklish than others.
Dragon Ball Z is known for its intense battles and complex storylines. Tickle fanfic adds an element of fun and playfulness. For example, seeing Goku or Vegeta in a situation where they are ticklish breaks the usual serious image of them. It's a different way to explore the characters' personalities and relationships, which is not often seen in the original series. This makes it stand out from the regular Dragon Ball Z fanfic.
