Uncle Scrooge is the only character in comics before the internet to have such a meteoric rise within five years from his creation. He started off exactly as his name implies, deeply grumpy, filthy rich, yet still feeling like he wants to reconnect with something, whether that be the outside world or his closest people. That suppressed glimpse of emotion was put into the core of his character from the start by Carl Barks. If that wasn't enough evidence, how about the fact that he caught on with the audience more than any of Barks' other original characters (including Mr. Jones, Magica De Spell and Gyro freakin' Gearloose!)? OR, how about the fact that with 1952's 'Only A Poor Old Man', just five years after his creation, one of the richest stories about him unfolded with him literally experiencing existential dread once he realises how little he truly is without his money? Or how about the fact that Tony Stroble was the first comic artist outside of Barks to use him, in goddamn 1951? Or how about the fact that Barks laid millions of little pieces of lore about him, which were later successfully interpreted AND twisted in many ways? Or how about the fact that his main characteristic since the mid 50's has been that he hides his sentimental side in favour of his 'tough, rich, grumpy, richest duck in the world' persona, in an age where comics where viewed as strictly kids stuff, with zero worth of their own? Carl Barks and Uncle Scrooge specifically are one of the main pillars of the modern comic and you can't convince us otherwise.
