In the Davy Jones story, Davy Jones was a sort of malevolent spirit of the ocean. He was associated with the deep sea and the fate of sailors.

Jessie is an important character in Toy Story. She's a toy with a lot of energy and enthusiasm. She has a backstory about being abandoned and then finding a new family with the other toys.

Giovanni could provide Jessie with better resources and training, which would make Jessie more loyal to him. Another way is through a backstory. Maybe they both had a difficult childhood related to Pokemon, which could create a bond between them.
