Louis (or Barney in english) is a character created by Bruno Enna and Diego Fasano. He was presented as best childhood friend of Donald Duck. He is a character of Paperino paperotto comics series.
Little Duck, unkempt hair, Louis was the best friend of Donald, perhaps the closest to him, as Donald Duck has a happy little relationship with Tom. Passionate about science and nature, like to explore the objects in the emporium of his father, Lester, finding time to useless junk times, but very useful for your adventures. Like Donald Duck, Luis enjoys reading and collecting the amazing science fiction magazine Papers. Also he likes to invent objects.
