The character leaks could be fake. The stage leaks are definitely real, though.
Right now it's unlikely that they're fake, the hackers got the files and the 8 characters mentioned are listed.
I can "hack" just as easily. It's called MSPaint. Take my documents tab, screencap, paste, begin editing. Done. As for the "decrypted" beta files, it's just as easy, and that's 100% fake. Do you really think SuperBot misspelled Spectre?
Specter is a character from Ape Escape and that's the way his name is written.
I thought it was Spectre? Maybe it's a localization thing or something like Skid(d) McMarx(x) in R&C1 (and UYA, for the letters in parentheses).
