One idea could be that Bonney discovers a piece of jewelry that has a mysterious connection to Lemon. Maybe it holds the key to a forgotten past or a hidden power. They then embark on a journey to uncover the truth behind it.
One possible plot could be that they team up during a strange adventure on a new island. Maybe they have to work together to uncover a mystery related to an ancient treasure. Luffy's carefree nature and Bonney's unique abilities would make for an interesting dynamic as they face various challenges like battling strange sea creatures and outwitting pirates who also want the treasure.
A plot could be centered around a shared enemy. Suppose there is a new and dangerous pirate who has a grudge against both Ace and Bonney. This pirate targets them separately at first, but then they figure out they are both being hunted. So, they team up to fight back. Along the way, they learn about each other's dreams and motives. Ace's dream of making his father proud and Bonney's dream of becoming the greatest female pirate in the world. This mutual understanding strengthens their bond as they face the common foe.
One possible story could be that Ace and Bonney meet during one of Ace's adventures. They start off as rivals, constantly trying to outdo each other in various challenges. For example, they might compete in a race to find a hidden treasure on an uncharted island. As they face different obstacles along the way, they gradually come to respect each other's skills and tenacity. Eventually, they form an alliance to take on a bigger threat, like a powerful pirate crew that has been terrorizing the area.
Well, it could be about Naruto finding a special piece of jewelry that has some sort of connection to Bonney. Maybe the jewelry has a power that can help them in their adventures. And Lemon could be involved as a friend or an enemy who also has an interest in the jewelry.
It could be someone from a different ninja village who hears about the special jewelry that Naruto has. They send out their best agents, and Lemon could be working for them secretly. So, in this case, the main antagonist would be the leader of that ninja village who wants the jewelry at any cost, and Lemon is just a tool in their plan.
In fanfiction, their relationship could be one of mutual respect. Bonney's strong - willed nature and Lemon's (assuming he has certain qualities) might make them equal partners in their adventures.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. Some fanfictions might focus on their adventures together in the One Piece world, exploring how their different personalities interact.
Bonney's power to manipulate her own age or the age of objects around her could be used in combination with Naruto's shadow clone technique. For instance, she could make a clone seem older or younger, confusing the enemy. Naruto's ability to transform into the Nine - Tails could provide a huge physical advantage in battles. Bonney could then use her powers to make parts of the Nine - Tails' body have different properties, like making its fur as hard as steel or its claws as sharp as diamonds, further enhancing their combined combat capabilities.
One possible plot could be that Naruto discovers a special piece of jewelry that has some sort of hidden power. Bonney, being a curious character, gets involved. Maybe the jewelry is linked to an ancient prophecy in the Naruto universe. They then have to go on a journey together to figure out the true nature of the jewelry and protect it from those who would use its power for evil.
