A plot could involve Master Roshi and Lemon going on a journey to find a lost martial arts scroll. Along the way, they face various challenges and opponents. Roshi uses his wisdom and combat skills, while Lemon uses her wits and any unique powers she might have. They might also meet new friends and allies during their adventure.
One plot idea could be that Master Roshi discovers a new form of martial arts with the help of Lemon. Maybe Lemon has some unique abilities that she shares with Roshi, and together they develop a new style that combines her special skills with his vast experience. For example, if Lemon can communicate with animals in a special way, Roshi could use this to train in a more nature - oriented martial art.
There could be a fanfiction where Master Roshi discovers a new form of ki energy. He then tries to teach this to Goku and the others. In terms of the 'lemon' which is often associated with inappropriate content, we should shift our attention to the potential of the story in terms of exploring the Dragon Ball Z lore more deeply. For instance, how this new ki energy could change the power dynamics between the characters and lead to new battles and alliances.
One plot could be that Roshi enters a cooking competition, and Bulma decides to help him out using her scientific approach to cooking. They combine Roshi's traditional recipes with Bulma's high - tech cooking gadgets and create amazing new dishes. Along the way, they face off against other competitors who are jealous of their unique approach. Another idea is that a strange alien race kidnaps Roshi, believing he has a powerful energy within him. Bulma uses her intelligence and resources to track him down and rescue him. During the rescue mission, they learn more about the alien race's motives and end up befriending some of the aliens who were against the kidnapping in the first place.
One interesting story could be Master Roshi imparting his unique wisdom, which is different from the normal Naruto teachings, to a young Naruto. Maybe he shows Naruto some unorthodox ways of chakra control.
They could also have a friendship - based relationship. They might share common interests like exploring new places or trying new types of food. They could have deep conversations about their dreams and fears, and support each other through difficult times.
One possible plot could be that Bulma creates a new invention, like a special training device. Master Roshi, being the curious and eager - to - improve martial artist he is, wants to test it out. This leads to a series of comical and action - filled events as Roshi tries to master the new gadget, with Bulma providing her scientific expertise and sassy remarks along the way.
The fanfic could also revolve around a mission. For example, there's a new threat in the Dragon Ball universe and Android 18 and Master Roshi team up to face it. Along the way, they have to overcome their differences. Android 18's cold - blooded nature (initially) clashes with Roshi's more laid - back and traditional approach, but eventually they find a way to work together effectively.
One interesting interaction could be when Android 18 challenges Master Roshi to a sparring match. Roshi, despite his age, shows some unexpected moves which surprises Android 18. This could lead to her respecting him more.
One idea could be to explore the backstory of the main characters more in - depth. For example, how did they start their journey in the world of Air Master? Another could be to create a new rival for the main character, someone with a very different fighting style. Maybe a character who uses some sort of air - based magic in a more creative way than what we've seen in the original.
Well, it depends on the specific fanfiction. Some might have really cool plots where Naruto's relationship with Roshi (assuming it's an original take) could lead to unique adventures, like facing new and different enemies together or uncovering some long - hidden secrets in the Naruto world.
Perhaps there is a situation where they have to team up to protect the Earth from a new threat. In the process, they discover feelings for each other that they hadn't expected. Their relationship then develops against the backdrop of this high - stakes adventure.
