The below description is taken from LEGO Book.
As the Viceroy of the Trade Federation, Nute Gunray has a lot of power. But instead of working for the good of the LEGO Star Wars galaxy, this Neimoidian minifigure is motivated by greed. Nute's well-dressed but miserable minifigure is the only Neimoiian to have been created in LEGO bricks. He appears in just one set.
