The timing's really unfortunate for baracat too considering Gen 7 is over and you can't even obtain him in the latest game, hype for Ultimate is now dead because of the GENIUS decision to reveal him and Ken last, and his relevancy in Smash will likely be usurped by a Gen 8 Rep in the form of DLC later down the line because there's no way in hell TPC and GameFreak aren't going for a double whammy.
