Definitively, no! The ‘One Piece’ world still has the strong marine officer, Vice Admiral Garp. This veteran warrior, known as the 'Hero of the Marines,' continues to make appearances intermittently in the manga and anime. Of course, being a high-risk profession, anything could happen in future, but as of now, he remains very much alive and kicking, influencing the storyline with his established reputation and strong moral compass.
So fans of this Mighty Marine, despair not! He's still around and may even have more core moments awaiting us in the plot!
