Once Upon a Time is adding another foe to its cast.

The ABC fairy-tale drama is bringing Captain Nemo and his infamous submarine from 20,000 Leagues Under the Sea to Storybrooke this season, with Faran Tahir playing the role. The news of Nemo's arrival, first reported by Entertainment Weekly, will not be good for the beloved Captain Hook (Colin O'Donoghue).

Once Upon a Time alum joins Timeless as James Bond author

"We're thrilled to give a Once Upon a Time spin to the classic character of Captain Nemo from one of our favorite Disney films, 20,000 Leagues Under the Sea," executive producers Adam Horowitz and Edward Kitsis told EW. "We're excited to see his mythology merge with Storybrooke's own captain — Hook. If for no other reason than to see the Jolly Roger go up against a submarine."

Captain Nemo arrives as Once Upon a Time brings The Land of Untold Stories into the fold. The new world has already introduced classic literary characters Dr. Jekyll and Mr. Hyde to Once Upon a Time, and this season will also include the Count of Monte Cristo (Craig Horner).

Pakistani-American actor Tahir has appeared in many television shows and films, including Elysium, Iron Man, Criminal Minds and most recently Supergirl, on which he played The Commander.

Once Upon a Time returns Sept. 25 at 8/7c on ABC.
