Saint's Corpse
The Corpse Parts are a key element unique to the plot of Part VII: Steel Ball Run.
About
At the beginning of Steel Ball Run these mysterious objects known as the "corpse parts" became the center of attention to both Diego Brando and Funny Valentine, but soon both Gyro Zeppeli and Johnny Joestar were after them as well. Feeling that they could not allow these objects to fall into false hands our heroes collected them and on the way met many of Funny Valentine's personal assassin and some neutral members such as Hot Pants. Yet the mystery remained at large as each corpse part was obviously giving our heroes clues as to were the next one was located. Soon enough possibilities of the corpse parts belong to once long dead Saint arose and who ever control them could become the new world leader.
The corpse parts act similar to the Bow and Arrow from the original series given those who are imbued with them Stand powers in Diego's case turning him into semi-reptile, this clearly a nod to his original vampire form in the previous universe. Each corpse part seems to react highly different with characters as Gyro gained a momentarily stand know as Scan while someone like Diego retained properties of the stand effect use upon him.
As of now some characters had have vision of the Saint, who clearly shows himself to be no other than Jesus Christ as to how his body parts arrived upon America is unknown. In one occasion Johnny was willing to go as far as to destroy one of the corpse parts as to not allowed his opponent from obtaining it, this action as said by Gyro was blasphemous and Gyro told him it be better to let fall into the hands of the enemy that being destroyed, this shows that Johnny clearly has a 'dark' side within him.
Lucy Steel was recently imbued with several corpse parts changing her and even given her a stand.
Also, the corpse parts are unique as it exists only in one dimension. This is shown when Hot Pants and Diego are chasing after the train upon which the president is on-board, they got sent into another dimension by him and in that dimension the president holds a diamond instead of any of the corpse parts.
