I have never heard of Goku, so Buzz Lightyear is probably more famous.
I would debate that....Goku - a character from Dragonball (153 episodes), then Dragonball Z (291 episodes) then Dragonball GT (64 episodes) , then there have been 13 movies with Goku in them coupled with the fact that the Dragonball franchise is worldwide and the fact that Dragonball has been around for many more years than Buzz Lightyear (Dragonball began in 1986) Plus add the fact that Hollywood did a movie with Goku makes me believe that there is an extremely good case that Goku is the more famous of the two.
Goku is more famemos cause his gracefullnice and his talents.

Buzz Lightyear
Harry Potter is more famous than Buzz Lightyear.
