Why are people acting like if Master Chief gets in as FP5 that it means the Cacodemon-Mallow hat leak is fake? Why are people acting like if the Cacodemon-Mallow hat leak is fake that it means Geno's chance of getting into Smash are lessened?
Chief getting in in no way lessens Doomguys chances, because the two are entirely separate, and even if you consider a superficial similarity and their both being from the definiing FPS series, we started the FP with two JRPG characters in a row, and had two FE characters in SM4SH's DLC cycle (one being a returning vet, but still).
And we've gone over the innumerable evidence for Geno's inclusion and why he's likely, and whenever Fatman posts his expose it'll all be in one place, but Geno was never going to get in just because there's a leak with a Mallow hat that may or may not be real. If it's fake, so what? Geno was likely anyways before that leak ever came along, and it's just icing on top of the cake rather than a make-or-break thing.
Saying "I don't want Chief because that means that Doomguy won't be in and that means the mii costume leak was fake and that means that Geno's chances went down the toilet" is silly. Chief would be awesome, and if you don't want him that's completely fine, but don't use Geno to justify that unwant, because Geno and Chief have nothing to do with each other here IMO
