Masked Man is pretty irrelevantI'm going to say it, everything relating to any potential SE rep, to me, points to Erdrick (Or Luminary).
1. Masked Man (An employee of Square Enix whose internet footprint immediately vanished following this statement) Said that the Imgur leak (AKA Heroes vs Villains leak) had characters (note the plural) that he knew for a fact were not playable. Sora, Geno and Mallow were all on that. That puts them all on Suspect
2. Tansut's (The Cloud 'leaker' from Smash 3DS/Wii U) words about a non-nintendo company (Widely assumed to be SE due to their wording and their history) being upset about a current leak going around at the time (October). There were many leaks about the SE rep at the time but there were very few characters detailed that actually reached the public eye.
3. Xenother outright saying Sora and Geno are not happening. While Xenother himself is an unknown as he has yet to prove himself, he has spoken with Vergeben and has been more than open considering what he knows. This slightly lines up with Masked Man's statements from around E3 regarding the Imgur leak.
4. Take all this together and assume it is true. This kills Sora (Who did have a 'leak' that was popular at the time in the form of the KH producer saying "Yes" to a tweet asking about Sora in Smash) and Geno outright. Crono and Sephiroth never had any leaks in the public eye to get SE upset about and if they did, they were fake regardless for other reasons we now know. This leaves the DQ Characters. Despite their credibility (which is the reason I'm only bringing them up now), LeakyPandy's VGA leak fits all these pieces. They strongly hinted at a character from a franchise that is nominated for Best in Genera which DQ11 was. They specified that it was not specifically a character from the game nominated, but from the Franchise in General. The timing of that leak Matches Tansut's statements about SE being upset which would make sense, since it was a leak that had specific information in it (regardless of the actual vagueness of the leak itself).
If I were a betting man, I'd be betting on Erdrick the most. Keep in mind, this is just my interpretation of the SE character chronicle over the course of this cycle. I'm not Saying it is for a fact Erdrick, but it's the one I believe to be the most likely considering everything that has happened so far.
Either Mallow and Geno aren't in and it's Sora which is pretty obvious or Sora and Mallow aren't in and it's Geno which is pretty obvious
Or, even more likely, he fell into SE's trap of catching leakers.
Xenother is going off of Verge's PM, where Sora is ruled out and it says we shouldn't take Geno "too seriously". Keep this in mind. Very in mind.
