Joseph's Birthmark Star

This birthmark appears in all people with Joestar blood as a star-shaped mark on the left side of the nape. Although Dio is not a Joestar, he has the birthmark on account of having grafted his head to Jonathan Joestar's body. After inheriting Made in Heaven, Enrico Pucci and Weather Report also have these marks on their bodies as the stand was partially originated from Dio's bone and they are biologically brothers.
