Morgan le Fay is the villain. Series finale. No Doomsday thread.

Why It Matters in the MCU

The final season of Runaways brings the alien Gibborim plot to its conclusion while giving the core ensemble their most complete character arcs across the three-season run. The time-travel element introduced in the final season is the show's most ambitious narrative pivot, and while execution is uneven, it reflects the creative risk-taking that distinguished Runaways from more conventional Marvel television. The series concluded before resolving all of its threads, which is a consistent frustration of the streaming-era Marvel television landscape.
