Well,that's one weird event on my point of view,because recently,Ubisoft,Rayman's company home,hasn't done much for Nintendo as of now,and if anything,they're been treating the company like crap since last year(or possibly since 2013),but I won't lie that I would be pretty happy to see the limbless hero in Smash.I guess it wasn't too hard to come with a moveset for him,because you'll already have an idea of how it will be by playing Origins or Legends,and some of his older games.Now,if Rayman going to arrive in Smash alongside a stage,I would say it will be the Glade of Dreams or the Snoring Tree,and possibly the Dark Teensie Magician as a Assist Trophy,as a guess.I have a sad prediction that if this is true,it will be paid DLC,and even less so if the money paid for the DLC goes to Ubisoft,rather than Nintendo,but still,at least Rayman now has a real purpose of being in the game,rather than a collectible trophy.
