Vile has his Shoulder Cannon at the ready and he’s a powerful maverick, but he’s nowhere near Luffy’s level. Luffy has his Gum Gum Punch and his speed is also on a different level. Vile can definitely take some tough hits thanks to his armor, but Luffy’s attacks will quickly overwhelm him. Vile just wasn’t ready to take on the future Pirate King! Luffy wins.
