  Ulises "Gree G." Tobar (born November 4, 1969) is a Chilean-born American artist, voice actor and writer.


  • He created Gree City with Greg Garfield, which is one of the worst shows ever because it has been said to rip off Greeny Phatom and Geo's World.
    • In it's later years it was made that way on purpose, so Robert and Ulises could pretend to hate each other.
    • Robert Stainton and Ulises Tobar are actually great friends, in real life. They came up with the rivarly after Gree City started to get negative attention, and Robert & Ulises went so far with their "rivarly", as to joke about a fake lawsuit.
