I played all 3 mother games and I'm a big fan, but what I'm saying he will mostly become a Mewtwo clone/semi-clone, because most of his attacks in both games are incomprehensible, most of the time it's a overwhelming physic attack that cannot be known in shape, form, and even name. While, Porky on the other hand links the two games who already have reps for the franchise, and has a boss battle to show how he can be seen in battle in Brawl. Personally my mother reps in most go in this order, Porky, Masked Man, Giegue, Ninten, other party members. I know most of them won't have a chance in smash. Yet, the top 4 are competing like crazy for the 3rd spot if there even is one.
