A possible plot could be that the Reborn characters are on a mission to find a special item that is said to be hidden in Lambo's time. So they have to team up with Lambo and use his knowledge of his own time period to search for it. Along the way, there are comical moments as Lambo's childish behavior clashes with the serious and often dangerous world of the Reborn characters, but in the end, they all grow to respect each other and complete their mission.
One idea could be that Lambo, with his time - traveling abilities, accidentally transports himself to the world of Reborn. There, he meets the characters and gets involved in their mafia - related adventures. Maybe he uses his ten - year - bazooka in unexpected ways to help the Reborn crew in battles.
Another idea is that his wish in this reborn state is to gain a power or ability that he lacked before. He could be an older Harry who has memories of his previous life where he was weak or powerless in certain situations. So, he sets out on a journey to find a way to gain this power. This could involve seeking out ancient artifacts or learning from a reclusive master. Along the way, he meets Lambo, who might become his sidekick or a rival depending on how the story unfolds.
It could be a new character who has the ability to disrupt both Lambo's time - traveling powers and the Reborn characters' mafia - based powers. This antagonist might be after a powerful artifact that Lambo and the Reborn crew are protecting.
Well, 'reborn x lambo fanfic' could potentially be a fanfic that delves into the crossover of the concepts or characters named 'Reborn' and 'Lambo'. It could involve a unique plot where the characteristics of both are intertwined. For example, if they are from different anime or fictional universes, it could be about how they interact in a new, made - up world. It might include elements like battles, friendships, or a quest they embark on together.
He could be developed as a character with a hidden past. Maybe he has his own reasons for being around Harry in this reborn scenario. He might seem like just a comical sidekick at first, but as the story progresses, it's revealed that he has a deep connection to the power or entity that granted Harry his reborn state. His actions and decisions could then be more nuanced, as he is trying to protect his own secrets while also helping Harry achieve his wish.
