Gilbert is an anthropomorphic dog.
Presumably the brother of Debbie, Gilbert is Goofy's nephew, and often stays at his loopy uncle's house. Unlike most members of the Goofy family, Gilbert is a precocious genius who already graduated from university as a young teenager and often cooks up inventions (though his is a more "grounded" sort of science than Gyro Gearloose's). Gilbert often tries to save Goofy from the consequences of his biggest goofs, and that includes relentlessly assisting his uncle in the guise of Super Goofy (sometimes becoming a goober-enabled superhero himself as Super Gilbert).
Behind the scenesEdit
Gilbert first appeared in the 1954 story Relative Genius.
