Superboy is making his full debut on Titans this week and he's bringing some classic Superman characters with him.

DC Universe has released the official plot synopsis for the second season's sixth episode, appropriately titled "Conner," picking up from Season 1's major cliffhanger of Conner Kent and Krypto escaping from Cadmus Labs. In addition to the confirmed appearance of Lex Luthor's longtime assistant Mercy Graves, Lex's father Lionel and Superman's adopted mother Martha Kent are both confirmed to appear, portrayed by Peter MacNeill and Sarah Deakins, respectively. The plot description and cast list from the upcoming episode are below

Conner Kent escapes from Cadmus Labs and emerge into the world for the first time as a free agent. With Krypto in tow, Conner's search for the truth about his past leads him to Lionel Luthor (guest star PETER MacNEILL), Lex Luthor's father, and Cadmus geneticist Eve Watson (guest star GENEVIEVE ANGELSON). Eve informs Conner of his true heritage and sends him on a path of self-discovery, examining his own identity and inherent impulses. In a moment of question, Conner chooses to act heroically and finds himself face-to-face with the Titans.

Season 1 ended with Superman's clone breaking free from Cadmus with Krypto. The original comic book character and Young Justice adaptation also had Lex's DNA, giving him the potential for villainy. Whether this shared parentage is intact in the Titans incarnation of Conner has yet to be revealed.
