I don't understand why some people thought he would he make it into this game. He has little to no role in any Mario game. He appeared in Mario Kart, Tennis, and the party games that's basically it. I expected him to come back as an assist trophy. Now we can move on, hope Ridley is dis-confirmed next.
It's quite obvious that he is going to be a stage hazard for the pyrosphere stage, I believe that's what it is called. Then there is something inside me that wants him in the game for the simple fact, that I want the Ridley request fans to be disappointed when Sakurai gives him the most bland to mediocre moveset in the game to the point that he isn't fun and no one uses him. Just like how everyone stormed Capcom's twitter for Phoenix Wright to make his debut in Ultimate Marvel vs Capcom 3, what a face palm request and the fans got what they want and in the end most people ended up being disappointed in him. Hardly ever see him used online and in pro tournaments.
