While "Batman V Superman: Dawn of Justice" continues production, new plot details have emerged concerning the characters in the movie. These characters reportedly have a direct link to "Suicide Squad."

A report from Badass Digest claims that by the end of "Batman V Superman: Dawn of Justice" viewers may have already seen not just Lex Luthor, Wonder Woman, Superman and Aquaman but also The Flash and Cyborg. Likewise, the assassin KGBeast and the villainous Doomsday will reportedly also make an appearance at some point in the film.

The supposed appearance of Doomsday brings to question the fate of Superman in the sequel. After all, in the DC comics the vile creature is responsible for killing Kal-El. Likewise, Doomsday's involvement in the film could mean a revisit to Superman's home planet, Krypton. Last fans saw of the planet it was blown to pieces in "Man of Steel." However, galacticnewsone speculates that instead of a mad Kryptonian scientist creating the monster, Lex Luthor creates Doomsday in his lab using General Zod's body. According to the International Business Times, a scene in "Dawn of Justice" will show how Lex managed to get hold of the general's corpse. Batman supposedly even sees Zod's corpse while raiding LexCorp for Kryptonite.

Lex Luthor may have a motive for creating Doomsday since per Badass he plans to make "his dark agenda a reality, an agenda that includes keeping an eye on all metahumans." Luthor reportedly even have agents working for him to make his agenda possible, including Anatoli Knyazev a.k.a. KGBeast. This wouldn't be the first time Batman's nemesis has been acknowledged as a character in "Batman V Superman: Dawn of Justice."

According to galacticnewsone, previous photos of the dressing rooms on the Chicago set of the movie shows one door marked with the name Knyazev. However, Faraci claims "Batman V Superman: Dawn of Justice" will show a different kind of KGBeast, not one with the cybernetic gun for a left hand. It's still uncertain how the assassin will be portrayed but Faraci confirms the name Anatoli Knyazev is on the script.

Aside from KGBeast and Doomsday, Faraci claims the Joker (Jared Leto) will have already existed in the sequel. Superman already knows about him, says Faraci, although physically he won't be in the movie. According to Movieweb, "Batman V Superman: Dawn of Justice (March 25, 2016) will likely help set up the events in "Suicide Squad (Aug. 5, 2016).
