One Piece: Season 1, Episode 391

Tyranny! The Rulers of Sabaody, the Celestial Dragons

The crew splits up in order to explore the archipelago. Hatchan, Keimi, and Paggag lead Luffy, Chopper, and Brook to find the mechanic Hatchan spoke of. In town, they witness a disturbance caused by a man claiming to be an escaped slave yelling for help in getting an iron collar off. To the Straw Hats' horror, the collar explodes, severly injuring the man. Two people wearing gaudy clothing and bubble helmets, Saint Roswald and his daughter Saint Shalulia arrive and callously shoots his body twice before leaving him for the Marines to pick up. Paggag later explains that they were part of the Celestial Dragons, descendants of the founders of the World Government, and that they have the power to summon one of the three Admirals if they so please.
