The experiment led him to realize that Devil Fruit users possessed their fruits’ fundamental abilities from the start, even before they learned to develop them.

• Sephiroth interrogated Vander Decken, read his memories, and learned that the Target-Target Fruit power passed through the family by eating a dying predecessor’s heart.
