In old comics from the 1960s and later, Goofy used to have a superhero alter ego, Super Goof. Toonopedia explains that Disney made a trial run in Donald Duck #102 (October, 1965) where Gyro Gearloose invented a super cape that Goofy used. The character was well received and
That same month, he got his own title, and Super Goof #1 (also by Connell and Murry) provided yet another origin story. This one involved a goober patch in Goofy's back yard, which, irradiated by a nearby meteorite, yielded super goobers which powered him up when ingested.
I am a bit confused about the line about the goobers connection to a meteor. It has been referenced in many places, it even showed up in an episode of Disney's House of Mouse. It is well known that Goofy got his powers from peanuts, or goobers as he calls them, but there does not seem to be any reliable source that show where in comic they attribute it to a meteor?
The first number of the comic Super Goof #1 (1965) says nothing about it, it only mention that Goofy managed to grow the goobers in his garden, but no mention about why they were so special.
Much later, in Super Goof #31(1974) the goobers were destroyed by the Beagle Boys which forced Goofy to get replacements. His research of the origin of the peanuts leads him to a Mexican superhero called Super Señor who had "superior goobers" on his ranch and who provided Goofy with new ones.
That is all the origin there seems to be for the goobers, so where does the meteor come in? Could anyone bring clarity to this?
