DIO's Bone

The term Dio's Bone refers to a finger bone belonging to Dio Brando, entrusted to Enrico Pucci before the events of Stone Ocean. After Pucci enlists Sports Max's power to bring it back to life, the bone becomes infectious; anyone who touched it would mutate upon contact, slowly germinating them until they became a plant. Once plants, the nutrients they absorb from sunlight were given to a baby like creature referred to as Dio's homunculus or the Green Baby. Upon the birth of the Green Baby, a part of Dio's soul was reborn into it, this part sought out Pucci and upon finding him he fused with his stand and created the stand, C-Moon. This stand was merely a placeholder for the final evolution as Dio slowly took over Pucci's mind and became one. Due to this, the gravity of the planet coordinated with his position, granting him Stairway to Heaven (Made in Heaven), a stand with the ability to accelerate time, a fusion of Dio's stand, The World and Pucci's C-Moon as it was able control gravity along with it. In this final form Pucci demonstrated several of Dio's tactics such as using his control over time to launch an attack of fast speeding knives at the heroes.

It should be noted that even though it's called 'Dio's' bone, it is actually a bone not from Dio's but from the body of Jonathan Joestar, whose body Dio took and placed his head onto after killing the protagonist at the end of Phantom Blood. Because of this, the Green Baby, and later on Enrico Pucci and his twin brother Weather Report (Character) each have the Joestar Birthmark on the back of their necks.
