Rayleigh would be a great candidate. He's an experienced pirate and has already trained Luffy for a while. He has a lot of knowledge about the world of pirates and could give Luffy a talk about the deeper secrets of the Grand Line or how to deal with the powerful enemies that lie ahead.
It could be about Luffy having an important conversation. Maybe it's about his dreams, his crew, or some kind of revelation he has. Without reading it, it's hard to say exactly.
Well, 'Luffy and Ace: Unbreakable Ties' is a fanfiction that I really like. It focuses on their childhood memories and how those shaped their relationship as they grew up. There's also 'Ace and Luffy's Great Escape' which is full of action. It shows their cleverness in getting out of difficult situations. 'Luffy and Ace: The True Friendship' is a must - read too. It simply and effectively shows the depth of their friendship.
In Luffy fanfiction, Shanks might talk about his hopes for Luffy's future as a pirate. He could mention how he saw the potential in Luffy when he gave him the straw hat.
Well, perhaps the fanfic could be about how Ace, Sabo, and Luffy's different personalities interact with the Whitebeard pirates. Luffy's carefree nature might bring some chaos and fun to the crew. Ace's loyalty and strength could earn him a special place, and Sabo's intelligence could be used to solve some tricky situations that the crew gets into while sailing under Whitebeard.
One type of fanfiction could be about Ace training Luffy in some special skills. For example, Ace might teach Luffy how to better control his Haki. This not only shows their relationship but also adds to the overall story of Luffy's growth. Another aspect could be flashbacks to their childhood, like the time they shared secrets or made promises to each other.
In some fanfictions, Ace might talk about Luffy's determination. For example, he could recall the times when Luffy faced seemingly impossible odds but still pushed forward. This shows Luffy's unwavering spirit from Ace's perspective. And it also helps readers understand the strong bond between the two brothers more fully.
Sure. 'Ace's Memories of Luffy' is a great one. It focuses on Ace's internal thoughts as he shares various tales about Luffy. The writing style is engaging and really brings out the emotions Ace had for his brother.
