The chapter where Luffy defeats Kaido is 1049. This battle showcased Luffy's growth and determination. It also had a ripple effect on the other characters and plot developments in the series.
Luffy uses Gear 5 in a significant battle towards the later part of the manga. But the exact chapter or arc can vary depending on how you're reading it.
The monkey is very smart. When he figures out that the crocodile is up to no good, he quickly devises a plan. He tells the crocodile about his heart being on the tree. The crocodile, being rather foolish in believing this, takes the monkey back. By doing this, the monkey not only escapes the crocodile's clutches but also makes the crocodile look rather silly. The monkey's ability to think on his feet and come up with such a believable lie is how he outwits the crocodile.
Luffy is still alive and kicking in the manga. The story keeps evolving with him at the center of the action, encountering new enemies and growing stronger.
In the manga, Hinata doesn't outright beat Kageyama. Their relationship is more about mutual growth and competition rather than one consistently defeating the other. Both characters have their strengths and weaknesses, and the story focuses on their development together on the volleyball court.
