Ascension (2)

The four teams fight a losing battle against their horsemen, until Apocalypse moves his plan to the next level. The tops of the pyramids come off and line the Earth's atmosphere, connected to each other by some sort of energy. Pressed for time, the teams become desperate. The Brotherhood joins the team in Mexico to fight Magneto, and Jean amplifies her power with Cerebro to battle Xavier psychically. Apocalypse lies down in his original resting place, and the evolution of humankind begins. But in the last moments of the battle, Rogue shows up with Leech, and she takes his power and negates Apocalypse's power, ending the evolution before any harm is done. Apocalypse is shut into his machine and sent to another time period, and the horsemen fall out of their trances. Rogue and Kurt give Mystique the cold shoulder, and the episode ends with Xavier deeply disturbed after seeing glimpses into the future of the X-Men, and seeing Jean become the Phoenix, among other changes.
