Monkey D. Garp is a legendary One Piece Marine who fought other legendary figures like Gol D. Roger and Rocks D. Xebec when they were both in their primes. He is now in his late 70s, which means that his physical abilities have diminished, but he is still considered one of the strongest characters in One Piece. A number of Marines possess Devil Fruit powers, but Garp is not one of them, which is unfortunate because there are Devil Fruits that would be perfect for him.
