This list, for some reason I disagree. It is because Mewtwo is not a bad character. Mewtwo's ranking should be higher. Donkey Kong, Luigi, and Dr. Mario do NOT deserve their places. In fact, they should be much, much lower than any other character. Donkey Kong is slow, Luigi has the worst recovery move, and Dr. Mario is just a weak clone of Mario. Roy also does not deserve his current ranking. If anything, he should be ABOVE Marth, as Roy is a more powerful version of Marth.
See, Mewtwo would have the upper hand against Fox with a perfectly timed down special, Roy would have an upper hand because of his power and recovery, Luigi and Dr. Mario would definitely lose to Link, and Donkey Kong would lose to Pichu in a self-explanitory way. Ganondorf would not be up higher than Luigi, because of his jumping height, speed of attack, and of course, weight. Yoshi deserves a bit higher, Link needs to go up 6 increments, Young Link by 5, Roy above Young Link, Marth below Young Link, Luigi and Doc below Bowser, DK below Pichu, and Mewtwo in front of Samus. By the way, Samus needs to be below Marth and Mewtwo.
