The stakes have never been higher. Marvel’s Runaways returns for its final season December 13th on Hulu. In Marvel’s Runaways Season 3, the Runaways frantically search for their captured friends Chase, Gert and Karolina. The kids go head to head with an unstoppable enemy who has targeted Leslie – or more accurately, the child she’s carrying. Nico draws them all into a dark realm where its ruler Morgan le Fay, played by Elizabeth Hurley, is much more nefarious than anyone the kids have yet to face.
