Chapter 503

Baby Face, Part 4 (ベイビィ・フェイス その④), originally in the WSJ release, is the five hundred third chapter of the JoJo's Bizarre Adventure manga. It is also the sixty-fourth chapter of Vento Aureo.

Summary
Melone tells Baby Face to remain unnoticed by the rest of the squad, not wanting it to be tailed back to him. Giorno notices that Bucciarati and Trish have disappeared from the turtle, and sends Gold Experience into the room. Before he can alert his squad, Baby Face cuts a cube out of Gold Experience's throat, wounding Giorno as well.

Unable to talk or breath, Giorno attacks Baby Face but gets pieces of his right foot and his right eye pulled out as well, forcing Giorno to crawl. Giorno takes the key out of the turtle so that the pieces of flesh which Baby Face hasn't absorbed force the Stand out of the turtle. Seeing Baby Face transform into a rock, Giorno is able to deduce its powers.
