The last characters that you should be able to get are Wolf, Jigglypuff, and Toon Link. There really is not a certain last character. You can get them in almost any order you want, but to get these last three characters you must beat the Subspace Emisary first. Then you must play The Swamp level to get Jigglypuff, or play The Forrest level to get Toon Link, and play The Ruins to get Wolf.
