Okay SmashBoards-Mewtwo hopefuls, we're here to speculate in this thread, right? Well, don't make fun of me but while I was taking a break from doing some illustrations (hence the Photoshop writing on the picture below) I was looking at the flier given out at the World Hobby Fair. I wasn't looking for anything in particular when I noticed that there were at least a couple of patterns used for the arrangement of the characters on the flier.
Pattern (A) As you can see, all the Pokemon are equally spaced apart in a pyramid, which might mean it's deliberate. Pikachu, of course, at the top of the pyramid, and below him are 5 boxes with Charizard and Lucario at the ends, and below that is what would be 7 boxes if the Mii Fighters didn't take up 3 spaces; at one end is Greninja, and at the other end is the hidden character.
Pattern (B) As you'll notice, the bottom row of the roster on the first page has 6 boxes. From left to right, there's 5 newcomers and 1 veteran. On the second page, the set up is the same, except instead of a veteran, it's the unrevealed slot.
Pattern (C) Let's just say for the sake of geeky speculation, the number of question marks as a placeholder for a name actually represent the same amount of letters that are in the hidden character's true name. There are 6 question marks. I borrowed this idea from speculations on other forums/commenters/etc. regarding the identity of the hidden character.
So let's connect the dots:
Based on Pattern A, the hidden character is a Pokemon.
Based on Pattern B, the hidden character is a veteran.
Based on Pattern C, the hidden character has 6 letters to his name.
To be clear, my intention wasn't to take this seriously, I just thought it was fun. Could this be proof of something? Even if it's deliberate, it's questionable. So let's just have fun with it yeah?
IT'S FREAKING MEWTWO!!!!!!!!!!!!!
