One Piece Chapter 18, page 15: Buggy, 'The Clown Pirate'

Buggy launches his detached hand holding knives directly at Luffy, shouting, 'BARA BARA CANNON!!' Luffy stands his ground and catches Buggy's incoming hand with a loud 'UGH!!!' sound effect. However, Buggy smirks and commands, 'SEPARATE!!' Luffy gasps, 'YIKES!', as Buggy's fingers detach from the hand he caught, still holding the knives and flying forward to slash at Luffy's face.
