X-Men: Evolution Season 4 Episode 9

Havok finally joined the X-Men.

Wanda's and Pietro's future are influenced by their Ultimate X-Men Counterparts. They are agents of the Ultimates, a special team under SHIELD.

Like Static Shock, which got cancelled in May 2004, this series had only 52 episodes and 4 seasons.

Unlike the last series, Xavier didn't die in the series finale.

These characters were all in the picture of the X-Men at the end of the episode:

Angel, Wolfsbane, Berserker, Magma, Iceman, Multiple, Cannonball, Jubilee, Colossus, Nightcrawler, Spyke, Cyclops, Jean, Rogue, Gambit, Sunspot, Havok, Boom-Boom, Storm, Xavier, Wolverine, Shadowcat, X23, and Beast.

Xavier has the last line in the series.

Nightcrawler looks a lot like he did in the X-2 prequel comics.

Gambit, Wolfbane, Jubilee, and X23 return at the end of the episode. They all have no dialogue, though.

Series Finale.

The coat that Rogue was wearing in the future resembled the coat that Gambit wears.

The older X-Men look the same except for X23, Colosuss and Storm. And Shadowcat and Iceman are slightly taller.

Despite all the images of the X-Men of the future, Wolverine doesn't appear in them at all.

Though Scarlet Witches' (aka Wanda's) memories of Magneto were erased, she still went to fight him.

If you look carefully as Jean and Professor X are fighting psychically, she makes a shield. When the Professor comes at her at full force, she powers up, and the shield she created takes the form of a Phoenix.

Xavier's visions of the future are as follows:
1) Anti-mutant demonstrations on Capitol Hill;
2) Magneto training the New Mutants: Wolfsbane, Jubilee, Cannonball, Magma, Multiple and Sunspot. Boom Boom is not with them;
3) Jean becoming the Dark Phoenix;
4) Adult versions of the X-Men, with uniform designs very similar to the "Ultimate X-Men" comic. The roster includes Iceman, Colossus, Shadowcat, Cyclops, Beast, Nightcrawler, X23, Storm and Rogue (who flies in). Jean is conspicuously absent;
5) Adult versions of the Brotherhood: Avalanche, Pyro, Toad, Scarlet Witch, Blob and Quicksilver, all agents of SHIELD. Perhaps the formation of Freedom Force...
6) Bastion leading a fleet of Sentinels;
7) An extended X-Men team, including Gambit, Colossus, X23, Angel, Boom Boom and Spyke.
At no point do we see Apocalypse, Legion, Leech, Mystique or Danielle Moonstar.
The visions appear to be following a linear pattern: anti-mutant sentiment brings about a renewed Sentinel program, with Bastion at its head. The fact that Jean manifests the Phoenix and does not appear with the adult X-Men in the next shot could indicate her fate.

Berzerker's powers become more advance than ever before.

Rahne and Jubilee come back as new recruits.

At the end, Gambit had his arm around Rogue. They also showed Rogue flying (hinting that she fully absorbed Ms. Marvel's powers).

If you look carefully when Jean hugged the Professor he says "Thank you, Jean" you can see he looks at her in a strange way, likely because of what he saw of her in the future.
