Why? You know what, I don't even know why. Maybe it's because of how delusional the idea of how people can even twist something like what we saw at the Smash Bros. Direct into saying, "Hey, that movement looks inconsistent as a boss character based on the shadow." It's a goddamn shadow, people. Of course your shadow is gonna look a bit inconsistent with your actual body proportions. It's been heavily implied that Ridley is going to be a stage boss for Pyrosphere since the PoTD and we even saw a flicker of his disc-like tail in the Direct. All signs were pointing directly to that very thing. It's not vague. It's just that Sakurai isn't ripping the damn bandage off by flat-out not showing Ridley as a boss and explaining it, so he's leaving people like you up in the air that, "Hey, he wasn't shown exactly! That means he still has a chance!" If that were the case, then Gardevoir would still have a chance because we haven't seen any gameplay footage of her too... Oh wait, except there was Gameplay footage of Ridley in the Pyrosphere where all signs pointed to Ridley because of the PoTD saying that an enemy from Samus' past would join the fight on the Pyrosphere. Again, not vague since we all know that Ridley fought Samus there in Other M.
So why do I care? I don't know, maybe it's because I would hate others to feel the same thing I felt when Ashley was not going to be playable when she could have had a lot of potential and was important to the Warioware series as well as bringing more females into the cast. But you know what? %$#@ it. I'll just wait until E3 when hopefully, Sakurai finally decides to rip the bandage off this time and show Ridley as a boss. Even then I doubt people would still believe he is playable because his movement looks "inconsistent" for a boss character.
Ughhh, good God I went on for a long time. I'm sorry everybody. I just had to let it out because of that right there. I'll just show myself to the imaginary door now... Why doesn't this place have a JonTron emote yet?.. Eecch...
