This marks the end of the series. The visions which Xavier has of the future contains footage which, had the series continued, would have been used in the fifth season; the continued persecution of mutants, Magneto reforming and training the new Mutants, Jean betraying the X-Men and becoming the Phoenix, the X-Men continuing to evolve and change, the Brotherhood joining S.H.I.E.L.D and a fleet of sentinels led by Nimrod.
Of all the mutants who appear in the series finale, Sabretooth is the only one who is absent.
The episode and series ends with a group photo of the X-Men, New Mutants, Spyke (formerly of the Morlocks), Boom Boom, X-23, Angel, Havok, Colossus and Gambit (both formerly of the Acolytes).
Professor X has the last line in the series.
