If this were as credible as the Simon leak? Yeah, sure.
But it's not and I'm afraid this is only but one fallacy for /v/ to fall into.
If people weren't even to take a guess to who Piranha Plant or Joker was much before their reveal and no one having OUTRIGHT GIVEN THEIR ACCURATE INTENTS, what makes you think """Erdrick"" is suddenly a exception?
And yeah, sure, I'll believe that one other guy I already forgot his name over ""Nintendo rep"" in regards to fucking Piranha Plant, even though that's as vague as it gets and let's pretend Nintendo would never, EVER, EVER take advantage of K. Rool's massive following not only overseas, but IN JAPAN and Isabelle's remarkable popularity over the years for the Animal Crossing series and the clear BIAS Smash will always have over having at least one Pokemon rep warranted for Smash and these new reps (excluding older existing ones) almost ALWAYS being humanoid and the ones broadcast in fucking movies and anime portrayals (""""Incineroar"""") of which I was deathly afraid of for a very good reason. Also yeah, fucking Ridley.
Although yeah, I can admit, if all this speculation just ends up being for yet another jRPG protagonist, I will be tremendously be disappointed about it unless it meets to everyone's expectations fucking somehow.
