Do you know who's fell off the fake leak bandwagon? Bandana Dee.
Prior to the August direct, he was in everyone and their grandma's leaks. Now, almost no leaks seem to have him, even leaks that swear by the holy tetrad of Geno, Issac, Banjo, and Skull Kid don't have him.
Weird thing is, nothing has changed about Bandana Dee's chances. No other Kirby or spear wielding character has been confirmed or even hinted at. He's still extremely popular in Japan, unique, and relevant. You'd also think K. Rool's confirmation and the confirmation that ballot results would play a key part in Smash Ultimate's roster would increase his visibility, given how well he did in that category, but nope.
Granted, this doesn't really mean much in the grand scheme of things, but you'd figure a character who has so much going for him would be on more fake rosters.
