Wilson Granger was the Prime Minister of the Mariposa colony and a clone of Captain Walter Granger, the commanding officer of the SS Mariposa and founder of the colony.

In 2365, he and several Mariposans were experiencing replicative fading due to being cloned several times over. After a brief attempt at stealing DNA from the USS Enterprise-D's crew, the Mariposans were reunited with the Bringloidi of the Bringloid V colony who were transported by the SS Mariposa in 2123, and had enough of a genetic base to create a stable society.
