If i remember right luffy used target CoC haki when in was in prison in wano .
It was vs weak people only and there no strong people but he still target them.
I don't think what Saturn doing is haki but DF power .
Still would CoC even effect Atlas since she a robo in term of making her faint lol.
So weakened shrivelled luffy > Sanji? Luffy can move but not sanji lol.
Don't think he was paying attention to luffy since he already so weak .
He get caught off guard when he saw luffy eating .
Saturn just rather mind fuck and torture a 12 year old and kill her , this man truly has issues
