A loyal follower and friend of Dio, Pucci aspires to implement a plan long formulated by Dio to "achieve heaven." Working as a chaplain at Green Dolphin Street Prison, he secretly frames Jolyne Cujoh and uses her as bait to lure Jotaro Kujo and his memories of Dio's Diary.

He is the twin brother of Weather Report

Whitesnake is Pucci's Stand, with which he may steal up to two discs from individuals, one disc contains the Stand of the target while the other disc contains the target's memories.

Pucci develops C-Moon with the instructions in Dio's Diary and with Dio's Bone, which manipulates gravity.

Pucci develops Made in Heaven, which steadily increases the speed of time. This Stand is the final metamorphosis in a chain following Whitesnake and C-Moon; one of the very last elements of the plan referenced in Dio's Diary. It was considered by Dio to be the ultimate Stand and the key to achieving "heaven".
