Their relationship could develop through mutual respect. Ace respects Shanks as a powerful pirate, and Shanks respects Ace for his lineage and his own growing power. They might start as cautious acquaintances, but as they face challenges together, like battles against other pirates or dealing with natural disasters at sea, they grow closer and become friends who trust each other.
Maybe Ace is on a mission for the Whitebeard Pirates and Shanks is just sailing around. They meet at a port town. Shanks recognizes Ace's potential and tries to convince him to join his crew for a short - time adventure. Ace is hesitant at first but is intrigued by Shanks' laid - back yet powerful leadership style. They end up going on a treasure hunt together, with lots of banter and friendly competitions as they search for the hidden loot.
They might have an epic battle to test Luffy's growth. Shanks could see how much stronger Luffy has become and be proud. Maybe Luffy will show off his new Haki abilities.
I didn't participate in the episode of Ace VS Ace, Flower Celebration, so I can't provide any relevant information. However, in general, Ace VS Ace was a TV series, and TV series were usually adapted from novels, so some books from novels might be quoted or appeared. If you want to know more about the novel 'Ace VS Ace' Hua Hua Qing Yu Nian, it is recommended to check the relevant online materials or consult other senior readers.
Well, it might involve Shanks sharing some valuable wisdom or revealing some secrets about the past. There could also be exciting battles or adventures as they face new challenges together.
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.
😋I highly recommend One Piece: Replicating Talent from Elbaf to you! This light novel was about a transmigrator in the world of Luffy, Sauron, Ace, and Shanks. Although it was a Doujinshi novel, the plot was very attractive, especially the interaction between the male and female protagonists and the setting of the copying talent. I hope you like this fairy's recommendation. Muah ~😗
