Once turned into 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 Stand seems largely to have been a placeholder for a final step, as DIO slowly assumed Pucci's mind and they became one. C-Moon's gravity manipulation allowed Pucci to perform the final step in the evolution, giving him Made in Heaven: a Stand able to accelerate time.
In this final form, Pucci demonstrates several of DIO's tactics, such as using his control over time to launch an attack of speeding knives at the heroes.
- It should be noted that even though it is considered DIO's bone, it is actually a bone from the body of Jonathan Joestar, whose body he stole, replacing Jonathan's head with his own head, at the end of Phantom Blood.
- According to the rules established in Part 3, it is because of this that the Green Baby, and later on Enrico Pucci and his twin brother Weather Report each receive the Joestar Birthmark on the back of their necks.
- The bone's particular shape and the presence of two round eminences (corresponding to the so-called sesamoid bones) indicate that it's DIO's first metatarsal bone, i.e. one of the bones within the foot behind the big toe.
