After losing to D'Arby, Joseph and Polnareff have their souls taken. In order to have their souls returned, Jotaro shows off Star Platinum's powers before going into a match with D'Arby, warning him that cheating won't work.
If they find out you're working for me, I'll kill you!
إذا علموا بأنّك تعملُ لحسابي، سأقتلك
Wenn sie herausfinden,
dass du für mich arbeitest, bin ich dran!
¡Si descubren que trabajas 
para mí, te mataré!
¡Si descubren que trabajas 
para mí, te mataré!
Si Jotaro découvre que nous sommes
de mèche, je te tue, petit con !
Se scoprono che sei mio complice,
sarò costretto a farti fuori!
Se eles descobrirem que você 
trabalha para mim, eu te mato!
