Monkey D. Luffy

Luffy has immense physical strength, and is capable of lifting up large boulders, breaking stone, shattering steel with his bare hands, lifting and dragging a massive ball of solid gold attached to his arm, pushing apart large buildings, and shoulder flipping a huge man; his strength was further proven when he effortlessly stopped a stomp from Donquixote Doflamingo, a tremendously strong man who is twice Luffy's size, with only one foot from an angle with no leverage.
