50 Days Left: Porky Means Business!
With Bowser Jr. being added, we got our first "mech based" fighter, and I'd love to see Porky make an appearance as well; Not only is he a major antagonist in the Mother series and a memorable encounter every time you come across him, but he would also provide a unique character archetype similar to Bowser Jr.
Are there any other unique fighter types you'd really like to see more of in Smash?
