Arguably the first "cosmic" comic book storyline, Fantastic Four #48-50 (1966) featured the debut of not only the "Emo before Emo Was Cool" Silver Surfer, but his giant bucket-headed boss Galactus as well...which makes it no mystery why these issues have become known as "The Galactus Trilogy". Since I've got a thing for the omnipotent types, I've always been fond of the planet-devouring, morally ambiguous Big Guy...even though his earliest appearances featured some endearingly goofy "wardrobe malfunctions".
In literally his first appearance, the final panel of FF #48 revealed Galactus in all his cosmic glory...which was almost canceled out by the big, dopey letter "G" in the middle of his chest! That's right...a universe-spanning alien space god inexplicably sporting an Earth alphabet letter as if he was some kind of sweater-wearing frat boy (or superhero)...inside of a white circle, no less!
In later reprints, the G-circle (and bare arms and hands) of Galactus would be re-colored to match the surrounding armor...but even with the more subtle coloring, that G still cracks me up every time.
Okay, so now you know where the "G" in the "Breezy-G" title comes from...but what about "Breezy"? The answer comes a few years later in Fantastic Four #74-76 as Galactus returns minus the "G" and...to paraphrase the bearded sages of ZZ Top...
He's got legs, an' he knows how to use 'em!
Note to Galactus: When issuing a fist-shaking Mighty Oath, it's probably best not to aim the camera straight at your baby-smooth bare legs and cosmic kilt. It kinda undermines the Cosmic Authority thing, you know?
