Supergirl divides its focus between comic book superheroics and the more realistic day-to-day concerns of its characters more evenly than any of the CW's DC Extended Universe series (likely because it was originally developed for the more conventional CBS network). But the series still manages to pack a lot of Superman Family "deep lore" into its ever-growing mythos - including Mon-El, Miss Martian, The Guardian and even The Man of Steel himself.

Now, the synopsis for the upcoming episode 'The Darkest Place' reveals that one of DC's deadliest villains will make their debut.

Released today by The CW, the breakdown for the November 21st episode of Supergirl drops some fairly significant hints about where the plot of several running storylines - particularly the fate of Mon-El and the continued villainous presence of CADMUS. But the biggest news is that the long-anticipated appearance of DC villain "Cyborg Superman" has been confirmed:

IT’S SUPERGIRL VS. CYBORG SUPERMAN — While Guardian (Mehcad Brooks) tries to clear his name after being accused of a murder committed by another vigilante, Supergirl (Melissa Benoist) heads out on a solo mission to rescue Mon-El (Chris Wood) who has been captured by CADMUS. While fighting to free Mon-El, Supergirl comes face to face with Cyborg Superman. Glen Winter directed the episode written by Robert Rovner & Paula Yoo (#207). Original airdate 11/21/2016.

Originating as part of DC's mega-selling Death of Superman and Reign of The Supermen storylines in the 1990s, Cyborg Superman was one of three beings claiming to be the original Superman "reborn" after his battle with Doomsday (the fourth of the Supermen, John Henry "Steel" Irons, made no such claim). Instead, Cyborg Superman was revealed to be a previously-encountered cybernetic villain named Hank Henshaw attempting to ruin Superman's legacy as part of a revenge plot.

Supergirl has teased Cyborg Superman as a villain before, with "Martian Manhunter" J'onn J'onzz using Hank Henshaw as his human name before his true identity was revealed midway through season 1. How the show's version of the character (who traditionally has powers and strength roughly-equivalent to Superman's along with other robotic enhancements) will originate is yet unknown, though many fans had already speculated that Supergirl and Alex Danvers' father Jeremiah - currently known to be a prisoner of CADMUS - will be transformed into a version of the villain. Notably, Jeremiah Danvers is portrayed by actor Dean Cain, who previously played Superman on Lois & Clark in the '90s.

Supergirl continues Monday, November 7 with ‘Crossfire’ at 8pm on The CW. 'The Darkest Place' airs November 21.
