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.
In fanfiction, when Sabo and Luffy meet again, they might have an emotional reunion. They could share stories of their adventures since they last saw each other. Sabo might show off his new skills or powers, and Luffy would be excited to see his brother again. They could also plan new adventures together, vowing to face any challenges as a team.
Luffy might be more confident and less like a little kid around Shanks. He has grown a lot, and Shanks would notice this. Their relationship could become more of an equal partnership in terms of respect.
Their relationship would likely deepen. They would have a stronger bond as brothers. They might understand each other's dreams and goals even better. Sabo would support Luffy's pursuit of the One Piece more actively, and Luffy would be more aware of Sabo's role in the revolutionary cause.
Several characters have met their demise in the MHA manga, but it's a bit complex to list them all precisely. Some of the notable ones include [mention specific characters if known].
I think it's hard to say for sure. There are a few characters who could potentially be the traitor, and it's all part of the mystery and suspense of the story.
I'm not entirely sure specifically as it could vary a great deal. 'MHA' might refer to 'My Hero Academia'. A 'fanfic' is a fan - created fiction. However, the 'diaper' part makes it rather odd and it could potentially be some sort of very strange or niche fan - created story within the My Hero Academia universe that involves diapers in some way, perhaps in a comical or very out - of - the - box scenario.
It depends on the specific situation and the character's personality. Some heroes might have moments of fear but overcome them through their determination and sense of duty.
