As far as I know, Fox cannot escape Meta Knight's Neutral B if it is mashed properly.Fox's SDI alows him to "pop" out of the tornado (much more easily than most of the cast, likely due to his light weight), directly above the center, and dair downward. This only depends on the timing of the SDI, and not on the spacing of the tornado...
ATL South has CT and Trump.
Also, Florida has Virg, who is pretty good (he's arguably better than Trump, but he's not very active).
