After arriving at Skypiea you enter into Upper Yard, the holy land where supposedly God lives in, after a while you notice that someone was spying on you since a while, you turn around and see a muscular man sitting on the ground with an arrogant smile, he doesn't have wing as the rest of sky people but some drums on his back.

Who are you to enter the God land's? Blue sea person, you will receive your punishment.

Still sitting points a finger at you, still with his arrogant smile, and unleashes a zap going towards you.
